Oil Question
 

my 89 gt has 113k miles, though I'm seeing the oil pressue getting lower then it used to be... so I guess my bearings are wearing.. and that's expected, I beat the snot out of it... but my question is this:

I run 10-40 in it now... just good old fashioned oil.... I think I should try something thicker... should I go 20-50 or just straight 50, I live in California, so it's not going to get really cold or anything...

what do you all think?

u can try a 15w50 weight.. or 20w50 would be ok too.. nothing wrong with thick oil..
