The Goods On Oils


PHaT MR30

Recommended Posts

New Skyline owner here, stock 1990 GTS-t Just did an oil and filter change, it needed it badly, was starting to make lifter noise and the old oil was quite black. Went into Repco to check what they had, and came out with 5L of their own brand (blended by Penrite) semi synthetic 10-40W, a filter and a bottle of Nulon engine oil flush, all for pricely sum of $49. Put half the Nulon in at the car park and drove it 4km gently home, then put the remainder in and idled for 10 mins. Drained for 30 mins screwed in the new filter and refiled with the Repco oil.

No more lifter noise, idle is smooth as and free revving, engine only has 60 000 on it and still seem nice and tight, oil pressure at idle is just above 2 and just under 4 when revved, oil consumption is next to zero.

Any opinions on Repco Semi Synth 10-40? Since this motor is quite fresh should I be looking some 5-30 for my next change, or should I stick to the 10-40 since I live Qld.

Cheers

Mike.

Can you post some specs on it? I honestly wouldn't trust something like that, they probably have developed it to undercut their other products and make a decent margin on it. Semi synth sounds av.

I would go for one of the full synths mentioned in this thread for $59, you don't need the engine flush crap.

Couldn't find a spec sheet at the Repco site, so the only information available is what is written on the package...

if its one thing ive learnt from owning a skyline, you cant go buy cheap shit like that, its generic repco stuff, you aint driving a commondor or ford anymore, these cars are performance!! I used to own a commondor and the oil was like $20 but now owning a skyline I get the good stuff $65 5litre bottle of 4100 MOTUL, you cant run cheap semi synth in ya RB, thats just a heads up, even if you do, you will probably have to change it more often

I mean even the cheapest oil out there is going to be fine for daily driving, it is only when you are out tracking it or giving it a good run through the hills that you want to better oils that don't break down and burn. However when the price difference is so tiny, you might as well get a known really good oil like Motul 8100 but don't spend more than that, eg the chrono oil etc which is over $120, that isn't value for money.

Leave it in there until next change, but next time go something a bit more quality.

The car is my new daily drive and it has an auto transmission so it's likely to never see a race track, a nice brisk run up mountain road is another story. At $36 including a free oil filter and being produced by Penrite convinced me to give it a try, if I can find the $60 full synthetic without having to travel too fare out of my way then I'll give it a go next change.

Go to your local autobarn, get the gulf western synx-3000

Probably one of the best semi synths out there and i rate it better than the nulon full synth

Will be on my 3rd change shortly

lol, motul's 4100 range IS semi-syn (that's what the "technosynthesse" on the bottle means)

not that there's anything wrong with semi syn, you need a mineral content to run ethanol based fuels like e85 and i ran my old 25 on 4100 turbolight for 3 years @ 300rwkw before it popped

    • So next year I am looking at upgrading from my VE SS bomadore ute to something more refined.  I wanted to stick with a V8 but not anything German or Australian, either a coupe or a sedan. So if I wanted anything newish that limited my options to either the Lexus RCF which I quite like. But with the price they demand and a kid on the way a 2 door coupe is probably not going to be the best idea. The next best thing would be the ISF but the newest models are 2014 and commanding over 60k and even the older 2008 models in ok condition starting around 35k is kind of bullshit. So I figured if I could not have the noise I could perhaps make do with easy power. Enter the infinity Q50 or Skyline equivalent. The price difference between the 300 and 400hp models seems a bit crazy. Right now there is 300hp Q50 one on carsales from a dealer with 61km for 27k drive away. If I wanted to get a 400hp Red or 400R car the prices seem to start at 43k From my limited research it seems that the only differences are that the 400r/Red Red runs more boost and a more aggressive tune. There are are turbine speed sensors on the turbos. Has 2 pumps for the water to air intercooler. Runs an engine oil cooler. I'm guessing that the exterior trims might look a little more sporty as well. I had a lazy look for upgrades to bridge the gap on z1motorsports They have kits that upgrade the water to air heat exchanger as well as the coolant pump which should give a non Red/400r better intercooling temps than the stock Red/400r. I added an engine oil cooler with a thermostat as well to try and make things as close as possible. Obviously the ECU is going to need a tickle. Having not done much in the way of research they also sell a ECU flashing tool with pre loaded tunes that are supposed to boost the non Red/400R by 100hp which adds 1k USD to the cost. The total cost of the parts @ the current time including shipping and taxes worked out to be $4350 AUD. Personally I would rather get the car tuned on a dyno which would probably add more cost Assuming the worst that you got a workshop to install the new parts I would guess no more than 5 hours would be required in the worst case @ 5 x $150 per hour = $750 So the total cost could be around $5100 So for easy number 5k + 27K = 32k I guess that would leave some change left over to swap out the open diff and fit a LSD Any thoughts?      
    • Right, not sure why I thought it to be a lean spike. It might be fixable with modern card-style hot film MAFs which have some design features to avoid counting reversion flow but I've never tried it myself.

    • I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.
