The Goods On Oils

[Galois]

Things like zinc additives do help add kind of a lubrication effect because of the "softness" of the way the zinc attaches to the engine parts, but this effect is dwarfed by the actual lubrication effect of the oil.

On the dark oil, birds said pretty much everything I thought of lol, he has a habit of that , but he's very right that it takes a tiny amount to stain the oil black, and that the oil absorbs the carbon into it's structure, the carbon can't really escape this to build up anywhere. The oil can take an awful lot of carbon before reaching saturation. It's not like once the oil is resting after a change the carbon all falls to the bottom of the container, it stays in the suspension because of the particular physical chemistry effects the designed additives have.

This is what Motul France recommends.

that is interesting that they recommend a 5w30.... motul aust recommend 5w40 for RB's

also the sump capacity is wrong. they state 4.5lt when it's 5.5

Haha Galois was waiting for your backup

Trying to find a clear cut answer on how much oil the gearbox takes is just as bad. In the end I just fill up oil until it's within the safe dipstick range, or in the case of gearbox and diff, fill up to the filler hole.

International recommendations = pointless. They are based on a completely different climate. France is cold as f***, it's no surprise they recommend something thin like that. Stick with the domestic arm if you're going to follow manufacturer recommendations.

Hi Guys,

I like this thread but its toooooo long for me to find what i am looking for.

I have a R31 with an Rb30/25 setup. R33 manual box and Full spool Diff.

What grades/brandes of oil is recommended for my setup? My usage will be 50% track 50% street.

I currently run penrite but going through some of this thread i didn't see Penrite get much mention, i;m more than happy to try others. I am looking to buy in bulk as well.

Engine will most likely be the same as for everyone else. Likewise for gearbox, except not so much info on that. Go with the recommended penrite syn or castrol if you want cheaper and throw in a bottle of nulon g70 additive (or is it g90, i can't remember, one is the replacement for the other).

No idea on the diff.

There is a transmission and diff oils thread in the drivetrain section but it's not quite as qualified as this oils thread haha

I have been reading this threat for a while now and can't figure it out and I'm new to the turbo piston scene, I just got my 2001 r34 GTT basically stock and want to do an oil change but not quite sure on what oil to get? Any suggestions guys? It's got 63000kms on the clock, is 10/30 ok? Street driven but I have a heavy foot haha lol.

[Birds]

You can't have been reading that long mate, that engine/car has been discussed on pretty much every page of it. Read the previous couple of pages and you'll find it there.

good god i must have been reading this thread for about 2 hours. Might as well add my 2 cents i have been using Nulon 15W-50 (street and track performance) for a few oil changes now and it seems to be ok. I was thinking of giving Motul a go and after reading all the people bagging nulon i'm leaning more and more in this direction. I havn't really seen the 15W-50 mentioned everyone seems to use the 10W-40, i was told to use a 15W-50 by the mechanic at Chasers so thats what i did ending up at nulon because it was 15W-50 and 'synthetic' and reasonably priced. Plus its good to support local companies (so i'm told).....after reading all this though my opinion hasn't really changed, when next oil change is due i will check out price of Motul otherwise keep with the Nulon.

[Birds]

No harm in trying different oils, try everything till you find something you really like

[ARTZ]

why is it mechanics always recommend 15-40/50 when car manufacturers recommend 5-30/40

[Galois]

Are these more specialised mechanics/builders, or your average falcodore servicing guy?

I've had a few mechanics who may be competent at the regular cars but I'd never take something different there.

Average...

10w40 is fine for most r34 gtt's but if yours has low kms you'd probably be right running a 10w30

i use the gulf western syn-x 3000 and have done for a while now, its good, its cheap but it just doesn't last as long as the sougi (motul 300v equivalent) did

but for $33/bottle you can't complain

its a 10w40 btw and i run it in a s2 stagea (rb25 neo with 108,000kms)

[drgtr7]

Thinking of using some different Motul 8100 ful syn. Anyone got any suggestions? It's for a standardish gtr

[drgtr7]

*then

[rehab2010]

*then

Then what - just use it. Pretty sure 8100 only comes in 5W-40, I have it in my car now for just over 2,000kms and no problems. Car runs smoothly, oil has turned dark brownish, can't notice any issues. I'd recommend 8100, either one.

[Galois]

Motul 8100 xmax is 10w40, released earlier this year or late last year

[Moodles2]

Best time to buy motul is when Repco have their Motul %20 off, I see them do this every 3 months or so
