Best oil?
 

I have a 90gt with about 150k on a stock 302 with with the bolts ons listed in my sig. I been using Castrol 10w30 just wondering whats the best oil to use, I live in south florida so its failry warm all year long, any suggestions on something different?

At this point (150,000 miles) I don't think I'd switch brands if I were you. :D

As a side note, I run Amsoil Series 2000 0W-30.

Well I think my OD rolled over cause it just reached 50k, I bought the car at 34k so I was just assuming it rolled and I use to use Valvoline 20w-50

In the summer i usually run Mobil 1 15w-50, and in the winter usually mobil 1 5w-30. Just out of curiousity 302LX eric why do you run winter oil. I take it that you run that just when its cold out?

I've always used amsoil. I think it's great oil. and use k&n oil filters.

I run the 0W-30 because it offers great protection when it's really cold out, and yet I still get a nice 30 weight oil for when the engine is running warm/hot in the summer. Plus it's a full synthetic so I don't feel a need to step up to something as thick as a 50 weight oil.
