its a 1990 twinturbo
i got it from the macine shop today now just waiting to put it back together
what type of oil should i us weight?synthetic?or a blend?
any help would be great

 

I would highly recommend using any 10w-30 dino oil. As long as you change it every 2500 or 3000 miles it will run a long time. Goodluck.

 

when you brake in the motor don't use synthetic because it's to slick and the piston rings wont seat correctly and you will not get a good seal. use petrolium (excuse my spelling I don't know if I'm spelling everything right) when you start it up and after 500 mile's or more you can switch to synthetic. All the info. I just wrote is from the instruction's I recieved while attending Universal Technical Institute in Illinois.
