Amsoil 15w-40 Maine Oil has ZDDP....no additives to make it slippery like molybdenum and it won't shear down to a 30 wt like conventional oil will.
Mercury and Volvo Penta make synthetic oils that you can safely run in marine engines too!
Mobil-1 V-twin is high in zddp

The best of the best for marine use!

thanks

These oils have the highest zddp...no enhancers to make the oil slick and are proven here on oso to work very well!

FYI, The regular Mobil 1 15w-50 5 quart jugs are out of stock at Walmart, except for what is on local shelves, from what I can tell.

NAPA does have quarts on sale for $5.99

Zinc level in the regular 15w-50 are still fairly high at 1300ppm. The VTwin is 1750ppm. Most other oils are 800-900

I ran into the non stock issue a few months ago. Nothing on the shelf. ​​​​​​​Went home and looked online at Walmart, in stock.​​​​​​ Got 15 gallons of mobile 1 delivered in a few days.

... if the cheapskate shoe fits, offer less for it... my advice to you is to drop this, but you got banned last time for not letting something die and starting numerous threads on it... doesnt matter to me, teasing people like you is fun. but its not fair to the moderators... your choice...

So is 15-50 the general consensus then? I don't have a 500efi or a 525 but Merc is still calling out the exact same requirements as listed above with the mercury nmma fc 4 cycle oil as the recommended etc etc.
