I'm running a Greddy TT now. What Oil specification (eg: 5w-30) is best for this type of application. (Let's not get into which manufacturer is best - I thinks that's been flogged to death by now.)

 

IMHO. The oil's characteristics is much more important than the weight. So unfortunately, you will have to discuss each maker's offerings.

But for FI, it HAS to be 100% synthetic. Question is which one. I'd go Amsoil and have it analyzed every 5k for wear.

 

Search the Oil Thread sticky on my my350z but I'm using Mobile 0-40, if this is good enough for GTM then it is good enough for me...

 

+1,000,000,000!!!

 

That is what im switching back to 0w40 mobil1 cause of its excellent ratings for our vq.

 

Wow a real consensus! 0w40 it is then. Thanks.

 

try red line 10w40

 

I've been using Red Line 5w30 until I got the turbos. It has Motul in it now. I'm just getting the info before I have to change it. I do like the Red Line.

 

I run Amsoil 10W40 Full Synthetic

 

Mobil 1 15-20 mmmmmmmmmm

switchin over to Motul though

 

what about castrol syntec 5w-30

 

Motul 300V 15W50....Amazing oil and in my opinion the best oil you can put in your FI, VQ engine.

 

I was running Motul 300V 5W40. I had it analyzed and I am not impressed. I had higher level than normal form Aluminum, Iron, and lead. That is pretty much telling me that I am having wear on the pistons, cylinder walls, and bearings.

Motul 300V 5W30 yielded similar results on someone elses FI VQ, too.

Right now, I am running Rotella T Synthetic 5W40. I'll see how that goes.

 

andrew, i am telling you, try some of our redline 10w40.


it tastes really good too!!

 

It's very interesting to see UOA of 300V
