I lost my manuel for my 97 Eclipse Spyder GST and was wondering if anyone else owns one, what grade of oil do you use and how much?

 

10w-30 and 4 1/2 quartz

 

5w30 would work well also

 

10 in summer 5 in winter. Sometimes sae 30 if it is going to be a really hot summer and i know im going to be driving it hard.

 

Synthetic or conventional, on a car with 150,000 miles?

 

so, where im from this is a well debated issue... Here are some of the different opinions

Syn - pro "better because high mileage vehicles need the extra protection for stickier parts such as lifters."
con - "high mileage engines have tolerances that are much less than they used to be, and a synthetic will slip past the seals easier." This one i know. less than a day after i switched to syn my valve cover gasket started leaking.

conventional pro- thicker to stick to parts better. Doesnt leak as bad.
con - its conventional oil... syn performs better.

So since no verdict was even come to.


But i use syn only because i have a hard time gettin in at 3K im usually in @ 4k... syn breaks down slower that conven.

 

I use conventional I heard some bad things about synthetic but what I hear it pretty much evens out between the bad and good.

 

i've allways run mobile1 synthetic 15-50in all my cars.it's the only oil i wiil buy. but thats me. find out for your self?

 

Synthetic 5W 30.. 4 1/2 qt

 

So how about my car? just got it. 98 GSX turbo, 110,oooish miles. Any help?
