I know this has been talked about alot, I did the searching and i couldn't really find an answer. So I was wondering first does mitsubishi actually reccomend a certin oil weight for the 98 GSX? I am running 5-30w full synthetic. Is that a good choice? the car has 60k on it.
anywhere from 5w30-20w50 is fine, no way is that too thick in a turbo car that makes so much heat. Basically thinner oil is going have less frictional resistance and *theoretically* give you a couple more usable hp but also burn off faster. Thicker oil will protect a little better and you wont be topping off as often. Take your pick. Id say most just run 10w30.
Thanks for all your help guys! I got this amazing coupon for Schucks auto parts. You can get a case of quaker state advanced full synthetic for only $ .99 a quart! There was an instant price reduction pluse a mail in rebate. So I had a couple of my friends buy them for me (since you are only allowed one per household) and now I have 4 cases that cost a total of $24. I bought all the oil they had. It was rad.
