The Goods On Oils

[Rolls]

When it comes to recomended viscosities, who are you going to trust..the manufacturer (who pays for warranty claims) the oil companies? or the guy at the store.

What if your car was made 25 years ago?

Sorry to sound stupid but from the first post should I consider Motul 300v to be the best oil to use? Where can I get some?

I have a R33 RB25DET daily driver so should I be using 10w30?

Thanks in advance!

I dont think 30 is high enough, personally id go for a 10w 40, if the engine is using oil then increase it to 50

300v is a good oil , its a mixed opinion subject, but most high quality synthetic oils are good enough, i prefer to pay more and feel reassured, I found Mobil 1 Gold to be a good one, currently using Royal Purple but might switch back next change..

[Rolls]

10w40 is what you want for our weather esp if you are tracking the motor and seeing higher temps. If it is predominantly a track car 50 or even 60 might be more appropriate, especially if it uses oil.

[Rolls]

Motul 8100 or sougi is better value, motul 300v is far to expensive for a daily driver. 100,000kms of oil changes and you could have bought a whole new motor LOL

[RobertoB]

It's only got 80000kms and doesn't seem to be using much oil at all, also temp needle never over half.

Previous owner said he always ran Motul oil but not sure which one, I'd like to continue using the same one because its a nice drive feel ATM, so 300v is the best choice then?

Also does the oil filter make a huge difference? It's got a light blue one in there now, can't read the brand.

sougi bit hard considering its off the road. i got a btach of mobil1 5w30 for free from work the other day put it in seems to be ok so far but when warm the oil pressure on idle sits at about 20psi on the autometer guage

[Moodles2]

300V is probably overkill for a daily at stock power, can't get it in 10w30 without mixing anyway. Maybe if it had 300kw+ on the street, or was taken to the track I would spend the premium for 300v.

4100 turbolight (10w40 semi-synth) would be more than suitable if it's a stock rb25det, next step would be 8100 (full-synth) x-max (10w40) or x-cess (5w40), then 300v (full synth double ester)

It honestly is a complete waste of money. Get a nissan oil filter and motul 8100 xcess or the full synth sougi one if anyone still has it (probably not).

300v is over $100, if you change it every 5,000 that is $2000 over that time! you could buy a whole new motor and have change for that haha.

I think mobil Gold is my choice, i never used oil using that one, now i use a little with royal purple.. so who knows lol

Thanks for the advice Rolls, I think I'll go the cheaper option Motul, does seem to make sense when you put it in the new motor perspective.

Now... Where do I get my hands on it? Supercheap doesn't stock Motul right? I'm in Sydney.

Where do I get a Nissan oil filter?

[ARTZ]

well nissan would be the most likely place for the filter..

repco have motul so does autobahn..

Get the 8100, i just use a ryco filter but whatever u choose.

$2000 over 100 000kms

for alot of people who dont daily drive there cars thats like 10yrs +, twice a year change, so $15/month for the best oil, but lets not go into too much detail here ok, lol

You are right, but most people will keep their skylines for what ~5 years before upgrading or moving on yeah? It is just putting it in perspective, the better oil really won't make ANY difference, might as well save your cash yeah?

Its not like it is an 8 second drag car where it might means you get 20,000kms out of the motor instead of 10,000.

yeah thats right,

could really just put shell helix in , probably wont notice the difference over a few years, i just dont like to skimp, but probably end up doing the rb30/25 deal eventually cause i dont wanna sell after spending thousands on it now..

Exactly, something I keep saying, 25w50 $5 oil will almost certainly not kill your motor, probably burn a lot of it and might clog the turbo feeds eventually but it won't be instant death.

[Galois]

Might not sound/feel as nice though

Roberto, the guys above are all dead right. I've never read a bad word about motul 8100 or 300v. But you can experiment with oils, see what you like. Just change every 5000km and you're sweet (some oils may last up to 10000km, your call on that).

On filters, I seem to remember buying k&n filters for $22. k&n are a fairly well known brand, the filter is almost certainly going to be better than ryco or nissan, and for a couple of dollars more I thought it was worth it. Also, and MOST importantly, it has a nut on the end so you can use a spanner to take the filter off when it's time for a change

[RobertoB]

Awesome advice thanks guys

The k&n with the nut, what a brilliant idea! Why don't they all do that...

Also does anyone have an image of where the oil sump bolt is?

Drift do on their filters too, I once picked up 3 drift filters for $20 each from autobarn on sale, was very happy. It's worth keeping a look out for oil and filter sales and stocking up.

Oil change diy, follow this and you'll be sweet.
