Now to my issue, Im unsure of what oil I should be using in my 97 3.1td trooper, I live in Tasmania so average winter temps are about 0-14 and summer can be 14-30s. So what are your experiences and thoughts on the best oil to use for these engines. Also I intend to wind a little bit more than stock boost into the turbo, dunno if thatll effect it as far as viscosity goes.
Cheers,
