Valvoline 20W50 Racing (mineral)

I used to use Castrol 20W-50 but switched to synthetic. Right now I'm using Mobil1 15W-50. I've also used Redline but switched to Mobil1 because it's cheaper. I think the car runs better and cooler with the synthetic. We'll see what it looks like when it needs to be rebuilt.

Mobil1 20W50 Syn. ( no OMP- premix)

Mobil 1 20W50

I run Bomdadier Synthetic Premix!

Shell Rotella 15W 40

or Castrol 20W50

castrol 20w50 all year. then again, we've used that in all our cars... except my turbo mazdas.

Looks like there are a few of us synthetic users around :)

whats with the castrol GTX
is this reccomended or something????

GTX 20W-50

Mobil 1 syn. 15w50

More or less, lol.

Seems to be one of the best non-synth motor oils around.

Also, its what quite a few of the know Rotary shops recommend.

castrol gtx 20w50 most of the year and 10w30 when it gets really cold

i feed my car castrol gtx 20w-50 :D

how come you guys dont use Valvoline Max life 10w-40?
thats what i use. should i switch? crap i just a case of it too.

i don't know... i thougth about using max life...

but the commerical specifically states, vavoline max life helps old engines feel new by reconditioning seals.

Fine i like that.

But then they said it reduces oil burn off

That is bad... rotaries inject oil during normal opertaion. So that means that the oil isn't burning away clean. That is bad.
