I'm thinking this may be a great product. From what Iv read about it. Know I run my boat pretty hard between 3500 rpms and 4600 all the time and gunning it
Out of the hole to jerk skiers up. And with hot AZ lake water temps. This just may be a pretty good additive. Has anyone had any luck with it. Thoughts?

Doesn't that stuff just increase the viscosity of your oil? If you want thicker oil, why not just buy a higher viscosity oil to start with? Also, if your motor oil has any beneficial additives, wouldn't you just be diluting them them by adding the oil stabilizer?

I don't think it will help much, as mentioned changing the oil type is likely best or just keeping with the current one and increasing the ratio or oil to gas.

Ok. What weight / brand do most like to go with. In my cars / trucks. Iv away just used used a the brand name that was on sale at the time. My boat manual recommend synthetic straight 30 W. But only thing I can find at auto zone is 5/10-30. Do you his thing a 10-40 would be a better choice for my engine. Thanks
