I have asked a few qustions on here but I really need to go back to the beginning and ask something very basic. What oil would you guys recommend for a 1993 RX-7 1.3L Twin Turbo rotary engine? I have heard good things about both 10W-30 and 10W-40 for my car and have been recommended both by different people. I know I really need to go conventional with a rotary. I have been looking at the conventional oils from: Castrol/Quaker State/Valvoline/Pennzoil and Havoline but have been leaning towards Castrol. Any of these brands better than the other? (By the way, my car is unmodified, I do not drive crazy but do drive "spirited" on occasion and I live in Delaware.)
Thanks,
Drew
