I don’t know how similar they are; I just know the Valvoline synthetic is a high quality diesel oil. It wouldn’t be recommended by Cummins if it wasn’t high quality.jyoutz I read that T6 and the Valvoline are
the one and same in quality and when I
run out of T6 will differently be using Valvoline
Running around looking for T6 is a waste
time and money!
