so for this engine it is recommended by international to run 15w40 fleetguard
I would like a synthetic but I will be using it in winter so would it be advisable to go with say a 10w or even 5w 40?
And being an older turbo diesel with 250k miles on it could I start running rotella t6? I am unsure what was used before. Could I run mobile1 extended performance instead?
any help would be great! Thank You!
