What Oil does everyone use?
 

I read that page posted by Bullzeye about buying a Supra and i was wondering what oil everyone uses in their Supra, and why if there is a reason? Please speicify if turbo or NA.

NA 10w-40 no particular brandchange it and filter about once every two months or around 3k miles

N/A, I use 10-30 but its got to be synthetic, a lot more safer at high RPM's:D and only the best for my Supra! I've also herd the Havoline and Valvoline are the best, there the least to "sludge up" no QuakerState, not sure if its true tho.

10-40. Synthetic is good stuff. I rate them like this based on my accounts:

1) Amsoil
2) Royal Purple & Redline
3) Mobil 1 & Castrol Syntec

Conventional oils are pretty equal to me, although I usually stick to Castrol.

Castrol GTX straight 40wt here year around in socal on my 89 N/A 177K mile car for the last 50K miles, Wix oil and air filters.

Geezer

Ya, Castrol makes some good oil. WHat I like to put in mine, and it consumes oil pretty well without it, is STP Oil Treatment. It's $3 and it's thick sh!t. SUppossed to protect the engine at start up. I doubt the brand of oil really matters as long as you stay consistant with the viscosity.
