That's not a gamble I'd be willing to take on a $20k engine. Run the manufacturer recommended oil.That may be what I end up running if I can find it around. I'm an amsoil preffered sucker for my hemi, so I'm debating on using their euro oil even though it doesn't say ms 1299 or whatever that code is. If your running a good 5w40 synthetic, you wouldn't think they would fight you too bad if she blows up
