Any updates on this thread? I need to change my oil in about 100 miles so im looking on what my best option might be.

 

im using Castrol Syntec, so far so good! No oil consumption or burning issues.

 

Nice. I'm particularly curious what the 6mt rev-ups are using. Anyone?

 

I was using Motul 8100 5w30, but after looking at the uoa thread on 350z, I have recently changed over to Mobil1 0w40

 

Updates. I'm changing it today or tomorrow

 

Bueller....?

 

I used to use mobil 1 5w-30 but now im using castrol syntec 5w-30 and it runs great.

 

Any difference on how the car runs?

 

recently switched from mobile 1 5w30 to 0w40.

 

Runs smoother during acceleration but that might be because its fresh oil. Ive heard that mobil 1 isnt truly synthetic but Im not sure how much different it is than the castrol oil. Mobile 1 is a lot cheaper though from what Ive seen. About $23 at walmart for 5 quarts i think

 

Well im told that I should be using 5w-30 and een that some of you are using 0w40. Why? Im still torn on which oil I should get

Based on these oil analyzes, I switched to 0w40. Again, based on these results, royal purple has mixed reviews, and German Castrol 0w30 and 5w30 and Mobil 1 0w40 seem to have more positive results than negative ones. I also feel that my fuel efficiency has improved a tad, just a tiny bit.

 

So what should I be using. I have a rev-up 6mt with 38k?????????????

 

I am not sure what your preferences are, but the general consensus seems to be German Castrol 0w30, 5w30 and Mobile 1 0w40.
