Gentlemen...
I have a ZZ502 bored/stroked to 557CI, 9.33:1 comp, mild tight lash solid roller, just shy of 700 hp @ 6000 RPMs
I used M1 V-Twin 20/50 for 4 seasons when this engine was a ZZ502/502 and changed the oil and filter every +,-20 hours. I like the VT due to the additives and high flash point/resistance to heat. The V-Twin is tough to get around here (central NY state). Think I'd be safe using M1 15/50 Silver Cap or should I stick with the V-Twin?
And no.... a few $$ more per qt. doesn't matter to me as I have a single BB with 10 qt. pan.
Thanks in advance !!

20W-50 V-Twin has 1600 ppm Zinc and Phos.
You do get what you pay for as ZDDP is quite costly.

This may be a dumb question, but why doesn't Mobile 1 and Amsoil market there best and most popular used oil on this thread for Marine use????? It seems the Mobile 1 V-Twin and the 20-50 Amsoil pass with flying colors for marine use why dont the Manufactures capitalize on this??

Viscosity question
I have a newly rebuilt 502. Fresh bore to .030 over.
I am comtemplating what oil to run, break in vs long term. I have some Mobil 1 15W-50W. Is this OK?
Boat is an 89 Checkmate 25' Convincer
Thanx,
Dave

Dave, run an oil with a lot of anti-wear additive. You have a flat tappet cam.
Most motorcycle specfic oils have high zinc.
Do Not buy an OEM brand. Mobil V-Twin, Motul, Spectro, Maxima.
Most of these are available at Metric motorcycle shops.
