What kind of oil should I use in my 98 GT with around 100k mi.?
Its for everyday drving and the occasional hard driving on the weekends. So what kind of oil and what viscosity should i use?
Also, what kind of oil filter?


Thanks

5w30 the oil of your choice, viscosity is more important than brand

Im in Texas, so its hot most the time. Does this make a difference?
What about oil filter?


thanks

mdvaldosta

temp matters, but not alot. Maybe 10w30 in the summer. If you get a lil smoke since your high mileage then move up to 10w40.

what kind of filter would you reccomend? And how many quarts does the GT call for?

Sorry... im new to the v8's

6 quarts, always change the filter. Buy the best brand of oil and filter you can get your hands on. Don't use the cheap stuff. I used to use Castrol but alot of members said they had problems with it.

I dunno, I use Amsoil anyway.

a guy at work told me to use motorcraft oil and filter since thats the factory stuff.

My 96 GT has about 107k miles and I use Valvoline Max Life 5w30 and Mobil 1 oil filter. You'll have to get 7 quarts cuz it holds 6.4 quarts with the filter.

I like to use a semi synthetic on high mileage engines. You get the best of both worlds synthetic properties against thermal conditions and natural oil for viscosity during normal day to day driving.

Ya, I was using semi synthetic on my 240sx and i was happy with it. I used the Castrol Syntec. So I may try that.
Damn.... I cant believe it takes that much oil.. These oil changes are going to get expensive.
