What grade amsoil is everyone using? The hvy. duty truck/marine or the regular 15w40.



Thanks

I used the 15W-40 HDD & Marine the first 105,000 miles, then switched to the HDD 5W-30 just for the heck of it. The truck now has 150,000 miles. It does have the BMK-11 (single mount) by-pass system.

I've got 55K miles on the 15W40 HD Diesel/Marine oil. But (as was pointed out in another oil thread) the Amsoil 5W30 is much closer to 40 than 30. So if I do much driving up in cold country, I might just switch over to the 5W30 sometime in the future.

I also have the dual remote bypass kit installed.

I have the 15W-40 HDD with 25,000 and a dual bypass system.
