turbolight is a pretty average oil. that's why it's so cheap. it's a semi-synthetic oil. the 300V oils are 100%synthetic ester.

I guess it all comes down to personal experinces and opinions, personally my car has run exceptionaly well with turbolight. Just because a oil is resonably priced (and lets face it a lot of the performance oils are marked up) doesnt make it a 'average oil' IMHO. If anything its a good buy specially when you change your oil every 5K's. A quality semi syn is a much better buy than a cheapo fully syn. Its not always clear cut as "aw its 100% syn so it must be better then a semi syn oil" (of course 300v is not a cheapo fully syn - so not having a go at you Beer baron)

The Semi Syn vs Fully Syn argument has been done to death on here and both have good for's and against reasons, but have yet to see a significant reason to use one over the other. Again, it comes down to what people have tried and what they belive makes their car run the best on. Two of the more significant things to consider are: 1, how often you change you oil and 2, what sort of set up your car is (eg daily driver, or track car). So its hard to say one oil is better then another, it all depends on what your cause is. I personaly cant justify paying $80-90 every 2-3 months for racing spec oil when i dont use my car on the track, having said that i wouldnt put any cheap oil in my car just to save a few bucks either. So again, this is why i think Turbolight is good in that, its a good performing oil at a good price.

Beefy: i think a 5W/40 might be a little too thin for a engine thats done over 120 clicks, again IMHO.

i think you should read up a bit more on oils, there are standards regarding oils which make it pretty clear cut why some oils are better than others, in relation to which others are saying turbolight is an average oil, beacuse it IS otherwise it would be specified otherwise.

how do you know your car has run exceptionally well? have you had your engine apart for inspection? have you have a used oil analysis done to see how it is wearing? just because it seems to run well doesnt mean too much.

your not knowing a significant reason for using full synthetic as opposed to a semi shows you dont really know too much about engine oils, so maybe you should listen to the guys who are telling you otherwise :D

have a read of the links posted in the thread and also have a look at

http://www.bobistheoilguy.com/

and maybe you might have a different view.

btw i am not against turbolight or anything i use it myself but not because i think its an above average oil.

Why are you considering Mobil have you read this thread?

yeah... in dribs and drabs....

ok so i have done some major research and i have re-thought my options:

1. Mobil 1 10w/30

2. Motul 4100 Turbo Light 10w/40 Semi-Synthetic

3. Motul 300V 4T Sport 10w/40 Fully Synthetic

My car is a 1994 R33 Skyline with 126,000kms on it with a rebuild performed around the 80,000kms mark.... so its only done approx 46,000kms on the rebuilt engine...

which one is best suited for me. please help me out and give me your advice, it would be much appreciated.

if you want to check what the 2 Motul oils i have chosen go here:

http://www.motul.com.au/product_line_up/4s.../4stroke01.html

I know all those oils I have tested them all. 300V is that different from the other 2 you have selected it leads me to believe you still need to read a little more but nonetheless it leaves the other 2 for dead!!

F*CK ALL THE OTHER OILS.....

PENRITE 5 FULLY SYNTHETIC 5w/60

This oil out performed all other oils in a comprehensive test carried out by "Street Commodores" including all Motuls, Mobil 1 as well as all Castrols and Valvolines etc... this oil came out on top with "Royal Purple" coming out second best...

anyone used or know anything about this oil... this is the one im getting now, all the others are very very poor in comparasin to this oil as the test showed.

what are your thoughts......

look at the pic for the oil in question

Read a post I put up on the page before, I have also tested the new SIN range from penrite and it is the bomb, especially considering the price, it outperfromed Repsoil, Amsoil, royal purple, redline, fuschs, titan in our test some of these oils are the same price for 1ltr as the SIN is for 5, it is thicker though. I read that street commodores test with interest and was glad to see there results replicated our exactly and our testing is pretty agricultural in comparsion but it is testing nonetheless. Both motuls are good oils but in the comparison beef was after i didnt consider the cost as he didnt seem to care so i stand by the fact 300v is still much better than turbolite, which used to be the best oil you could get for the price, we now have a new winner!!

yes very true, This Penrite 5 Fully Synthetic oil appears to be unbeleivabley well performing...

it is the only oil in my mind now, im going to flush out all my old shit Mobil 1 and replace it with a half decent oil....PENRITE 5 Fully Synthetic

anyone else seen this testing carried out by "Street Commodores"....?

Beef

i had a quick look at the specs for the penrite 5 oil

http://www.penrite.com.au/files/WKRXR86PLF...E%20OIL%205.pdf

i dont understand all the figures but from what it looks to me like its way to thick when cold and maybe also a bit too much when warm. (although not doubting its outright protection capabilty in terms of sheer etc.)

wouldnt this result in high wear on cold starts?

can someone explain?

dont forget there is a big difference between 100% synthetic oils. 300V is 100% synthetic ester. some others are not a synthetic ester. from my (very limited!) understanding the synthetic esters are the go.

yes it's pricey. as and for intervals of replacment that is probably hte most important thing, even more so that oil choice. i change my motul chrono 300V probably every 2000kms or less. factory interval for warm climates is i believe 3000kms, and that is for a standard car. if your car is modified past standard it is a good idea to drop that to 2500 or less depending on the type of use (track etc)>

Yeah i saw it, and came to the conclusion it didnt mean much. If you put a heavy diff oil in that test it would have shit all over the other oils from a great hight. That doesnt mean you want to use heavy diff oil in your engine... The oil manufactures do hundreds of different tests, and the big names havent gotten it as wrong at that test might indicate. Mobil runs large banks of smallblock chevs running 24x7 to verify that the theory actually works in practice. That sort of testing is far more informative that the one run in Street Commonbores.

Think about it this way - how much money do you think Mobil et al spends on R&D? Do you really think they would have missed this?

ok, obviously you are a fan of the Mobil 1, but can you explain the difference in the two products:

The Mobil1 in the SILVER 5 ltr "Jug" is $54.99 approx for 5 ltrs

the Mobil1 with "SUPER SYN" in the GOLD 5 ltr "Jug" is $74.99 for 5 ltrs approx....

what is better about the GOLD Mobil1 with "SUPER SYN" compared to the normal Mobil1?

Beef

factory interval for warm climates is i believe 3000kms, and that is for a standard car. if your car is modified past standard it is a good idea to drop that to 2500 or less depending on the type of use (track etc)>

What's considered "warm" BB?

GTR service manual says 5000kms, but does not specify climate. Thats for oil available 16 years ago. The oils now are far superior. Some say that oil is the most technologically advanced part of the engine.

IMO if you're spending $20+ per litre on oil, it would be well worth getting a used oil analysis (UOA) done rather than aribitarily changing at 2500kms. You might be throwing out good (and expensive) oil unecessarily. The UOA can also provide info on engine condition etc. I *think* there was a group buy for UOAs - $40.

FWIW I know of someone who used to do regular UOAs on his Porsche 928S4 and the oil was still recommended for use after 20,000kms, which is twice the recommended drain interval. A low stressed motor with large oil capacity, but the oil was only a relatively inexpensive Shell Helix.

I dont know if i'd say i'm a fan, but i'm currently using Delvac 1 5W-40 which is supposed to be good, probably better than some/all of the Mobil 1s. I'll look at Redline next time as they appear to be better oils based on the specs, but if there's a lot more expensive i'll stick to the Delvac, which is costing me $15/lt.

Re the different ones, i dont know - just check out their website and make sure you note the weights - that's the important bit. IMO you dont want to be running a weight of 50 or more (so Mobil 1 5W-50 is out) unless you've got a problem with oil temperature, and if that's the case fix the oil cooling system! ;-)

Rgs,

Kot

Delvac is a very good oil and always comes out good when we have tested it. Mobil is a petrol company first and foremost never forget this!!! I would always use a dedicated oil company over a fuel company. Penrite, royal purple, red line will have inconsistancy in their oils as there base oil is supplied and there are very tiny variances in the quality whereas mobil can achieve the same product everytime as they can get rid of oils that perfrom differently to their exact specs- ie sell them to another oil company, so at the very least the big company's have a good consistant product.

Getting back to your comparison diff oil would simply sheer off, over heat and not perform anywhere near what some of the other oils did, you cantssay otherwise, so that is a very misleading comment!! Also keep in mind who is doing your large scale testing- their testing their own bloody product then releasing the info of course its going to be a glowing report of themselves you think they would let it be any different! Large companies like mobil shell are driven by operational costs and getting the most they can out of the cheapest products to meet the bare requirements asked of the OEM company's they supply and thats the bottom line!!

from memory warm climate is somewhere that gets above 30 (not over 40 though) and never below minus 10. or something like that. as they print stuff for europe too. and having just checked what i can lay my hands on here atm it seems i was talking out of my arse. sorry. 5000kms is all i can see here.

the UOA is a good idea for sure. i've done it before and will do it again at the next change (will use the $40 gb too).

but this is for the GTR with a (japanese) rebuilt motor. in the GTST it's 5000kms and cheaper oil. :D

    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
