If it is just for road use then go for 5w-40, if you do track to then go 10w-50.

Cheers

Guy.

Mobil 1 15w-50. I think that the bad press on the quality of this oil is nonsense. That being said I'll probably change to Silkolene Pro 10w-50 after the next change. Running 510 bp atw.

Thanks Oilman but which make would you recommend for it?

I won't be using it on the track!

Cheers

What are the experiences with oil-consumption on the R34 GTR?

Silkolene or Motul come out top. You shldn't be using much oil, if any, with an R34 GTR.

ok, some questions here:

the cold rating, with the "W", isn't lower better? 0W or 5W making cold starts smoother and better flow, promoting cooling? and a 50wt is a 50wt at 100 degree operating temp, no matter if it's a 0W-50 or a 20W-50?

I ask because, in lieu of Motul 300V 15W-50, which I got to use for 500km before the oil pump blew out, I'm thinking Eneos 0W-50 or Liqui Moly 5W-50? Are these crap oils that cannot sustain 50wt qualities at high temperatures?

My car is going for some fairly big numbers powerwise but is purely a street machine. It took a solid 20minutes to get up to 70 degrees with the 15W-50 and oil temps rose slow as molasses.

You are quite correct.

However.... 5w-50 and 0w-50 oils are not popular for one reason. Because of the huge viscosity gap between 5w and SAE50 the oil has to be rammed the viscosity improves to help the oil stay in grade, these are consumables within the oil so soon will go from 5w-40 to 5w-40 to 5w-30.

In short they are not as stable as a 10w-50 or 15w-50.

Cheers

Guy.

this thread is indeed invaluable. With the addition of a Greddy oil cooler, I'm trying out Castrol RS 0W-40 today. I figure so long as oil temperatures don't get too high and stay under control, there are too many benefits to thin oils to avoid using them.

In fact, if it came down to it, I'd add an electric fan to my oil cooler radiator before switching to some molasses thick oil.

And you are quite right.

Why people insist on the likes of 10w-60 in cars that don't warrant it totally baffles me. A lack of understanding of what the parameters are and the damage that can be caused by using thick oils in the wrong application.

Cheers
Simon

Castrol Edge 0w30

Just had a service, and my engine filled with this - any comments by anyone (especially Oilman - as his reputation supassed him).

My car is stage 1 - and probably around 320bhp ish (I would like to think).

I dont race it, but do give it some stick between 0 and 60, because you just have to.

Was looking to have 15w50 in it originally - what difference will this make?

Cheers

So far so good with the Castrol RS 0W-40 I loaded up with four days ago. Quicker warmup, and the car now likes to hang out around 80-90 degrees instead of 75 degrees oil temp. As summer approaches...it might be thin but my Greddy oil cooler just arrived

I'm sold on thin oil - the engine feels so much more fluid, if that makes any sense. Motul 15W-50 (the previous oil) must be honey thick. What could be gained from that??

Its a good quality oil, but really designed as a long life oil.

It should be fine, but I would be more happy with an SAE40.

Cheers

Guy.
