Best Answer

Best oil for any diesel is Rotella

a little higher to buy, but by far the best oil

Tests say other wise.

Shell Rotella T 15W-40

Four-Ball Wear Test

(ASTM D-4172B @ 40 kg,75°C, 1200 rpm, 1 hr), Scar, mm 0.636

Noack Volatility, % weight loss (g/100g) (ASTM D-5800) 10.86

AMSOIL Synthetic SAE 15W-40 Heavy-Duty Diesel and Marine Motor Oil (AME)

Four-Ball Wear Test

(ASTM D-4172B @ 40 kg,75°C, 1200 rpm, 1 hr), Scar, mm 0.35

Noack Volatility, % weight loss (g/100g) (ASTM D-5800) 6.8

Costs less also

Hope This Helps.

having run all size trucks from road trains to pickups i have proved that rotella is the best

i have had cummins,mack,cat,Ford and international diesels, Volvo and Detroit

the 4 ball test was payed for by amsoil,course it would say it was best

take yourself along to any truckstop in the nation and see what oil they sell, they sell rotella not amsoil. and you surely do not need heavy duty marine oil in a truck engine.
