Mercury DFI Oil, or Mercury Premium

[Dave Stewart]

If you have the XS model it calls for Premium...otherwise you need to use the Opti Oil.

I'm probably going to open a whole can of worms here. I went to Valvoline's HQ here in Lex this past summer. I saw piles of test data on Valvoline brands, Mercury brands, and about every other brand you can name. Amsoil, Pennzoil, you name it. I was asked not to publicly discuss who makes Mercury oil, but now that I know, if I had a opti I wouldn't run Merc oil in it. Now, don't get me wrong, i've never been a Valvoline fan but, after seeing the tests, I'd go with Valvoline and then Amsoil 2nd. Valvoline also has a biodegradable synthetic on a limited basis. If you want to know more about what I'm talking about on here, call John Webb of Marineworks at 859-509-6660. He is tight with someone at valvoline and knows far more about it than me.

Okay how about Pennzoil SYNTHETIC with an Opti? NON-XS Model.

Not sure where i seen a test on different types of oil and yama lube was the only oil that had antiwear in it so i'll run it and only it.I allso have a snowmobile and run only what its called for too.I learned too run the type they call for because of all the snowmobiles blowing up because they tryed too save a buck and run cheaper oil.Cheaper don't mean better in my book.Just me but my sled is a 2000Yamaha and has been rode every year since then even though i live in Ky.Last time i rode it was in 06 and we went for a 600mi+ trip.It had about 3000miles then.Bet my freinds grand kids have a ball on it,thats why its in Mi.I sleep better at night knowing i have the right oil(lol)Terry Adolph
