Been using synthetic in our 4 stroke out boards for years. GREAT!

and I am talking tour boats with thousands of hours.

What kind of synthetic would you use in a diesel??

I use Castrol Syntech in my diesel. It's a synthetic blend that has the
CF rating and isn't as expensive as a full blown synthetic. I think
synthetic is a waste of money if you're still going to change the oil at
the recommended intervals AND if your engine is not running at the very
high temperatures that bake dino oil.

There are only a very few straight dino oils that are rated for diesel.
In fact, off the top of my head I can only think of Shell Rotella-T.
All the normal stuff you see at Pep Boys shouldn't be used in a diesel
because it doesn't have the Cx rating.
