Default Eclipse Engine Oil Weight

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.

See thats the thing I looked up the oil in the index of the manual and it just says use API certified oil or whatever. It doesn't say anything about weight. The oil cap doesn't eaither.

5w30 is good. That's what most DSM'ers run in weight. 5w40 is "too thick" as it will run your oil pressure up a bit.....I don't mean that it's going to blow a head gasket

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.
