Shell Rotella T 15W-40. Use it in everything. Never had an issue in 20+ years. Any heavy duty engine oil in straight 30 or multigrade 40 will suffice.

Your question is just an open invitation to get a different opinion from everyone who responds to it. How's that going to help you?

Your engine manufacturer publishes all the specs you need (weight and certification) to use any brand of oil you choose. Anything that meets those specs will be fine. If there's a particular brand you're partial to in your car, you can use that.

Oh- and read the manual

I've said this a thousand times on a thousand different oil threads (they are very common)
IF you don't want to use what the manufacturer recommends, then use whatever you want. Someone on this board has already used it and thinks it's the best thing since sliced bread.
As long as you change the oil and filter every 100 hours or yearly, (which ever comes first), as the manual recommends, you won't have any problems.
I have never seen an engine damaged due to the type of clean oil and filter they use. Water and lack of maintenance is what destroys marine engines, not type of oil.

Thats what we also use in our 5.0 Volvos. You can buy a 2.5 gallon jug at walmart for a great price. We also use Mobil 15w-40 synthetic for our 4.3L Volvo Penta.
