I always use Castrol GTX 10W30, but I was reading on rx7.com that turbo rotaries should use 20W50. How true is this? I noticed that my car started smoking a little bit, most noticeable when pegging the gas pedal on idle, fully warmed up BTW.

Thanks

May 2004? I was expecting to come in to see a Dec 2007...

Depending on climate, a lot of FD owners use 20W-50 in summer, 10W-30 in winter.

That is exactly what I am doing, LOL, but I read the Rx7.com thing and I was like, WTF! Anyway, much appreciated.

also go for more viscous if you're leaking any, for obvious reasons

10W-30 is fine for all around weather/driving.

Hotter climates, long city driving (especially in warmer areas), track driving, 20W-50.

I run the crappiest 10W 30 I can find. Never had any issues.

Not hiding under a rock, LOL. I should've put my flame retardant suit on. Flame on, flame on.

I've had lots of FDs, they all get fuel dilution if driven under boost much. Given the fuel dilution issue I'd run the thicker oil 20W50.

BTW I never had to replace a set of turbos!
