Oil Types Used

[TADTOOMUCH]

What are most F-32 owners using for motor oil?

30 Weight or a multi-viscosity?

Synthetic or Not?

Does anyone have the oil capacity of a Chrysler 360 cubic inch?

I use Amsoil 20W-50 Severe Service synthetic oil in my 300hp 350 Chev (Mercruiser). It's expensive stuff but I only have to change it once a year and I don't worry about oil related failures. I also use it in my generator simply to keep all the on board engine oil common.

I use Rotella-T 15w-40 in my diesels.
I use Mercury 20W-50 in my 454 in my other boat.

Synthetic is great stuff - I use it in my old Vette.

Multi-Vis is best, unless you live where it stays above 80 all the time.

I use Rotella-T 15w-40 in my cummins diesels , but I also used it in my last 3 gas boats .

318 in my F28 Oil used Rotella T 15-40 these older engines need the zinc additives for the cam and lifters, reason diesel guys like this oil also for the additives. Although I may switch to Delo soon as I hear the new Rotella T is formulated with less zinc
