Oil Change

Postby barrymeade » Wed Nov 17, 2010 7:24 am

Greetings,

I've got a 98 Trooper 3.1D and use 10w 40 diesel oil, changed every 5k (oil filter also changed). Is 10w 40 the best oil to be using for my machine? Can I use another such as 15w 40 or even 0w 30, and what would be the outcome?

Thanks in advance

I always use 15w40, have been for years, most large trucking companys, use 15w40 in their diesel rigs and so does Ryder and Penske rental fleets.
I live in my own little world, but its OK they know me here.
Happy Trails, Wayne

More important is the grade ie CF4 CG4 etc. Dont use less than CG4 but there is not a lot of benifit going to CI4 etc on that engine. Also no point going to the 0w30 which will be synthetic unless it gets very cold where you live
Sanding your knuckles before starting work can help. That way you cant skin them
