Synth's?

[Rodslinger]

Hey have any of y'all ever run synth oil in your Bikes or Quads? I'm getting ready to change my oil on both my quads and thought I might run Amsoil. Any thoughts?

[Brian]

do the owners manuels say anything about running syn. in them?

[Rodslinger]

Sure doesn't Brian, it just says 10W40.....

I have a few buddies that run Amsoil in their 4 stroke dirtbikes (trailbikes, dual sports?) and Streetbikes. All of them have said it feels like they have more power and smoother idle. Also, it's cheaper than the manufacturer labled oils you get from the powersports dealer.

See if this helps -

We used Valvoline Syntec and Kendall 20W-50 GT1 in my 400EX when we dynoed the new engine. In my Honda, the engine oil lubricates the clutch as well, meaning synthitic coats the clutch and smokes it. The clutch was getting replaced anyways, so we compaired the 2. GT1 got me 52 Hp. @ 8200 rpm while the Syntec got 54 hp @ 9000 rpm, plus moved the redline to almost 11,500 rpm. If I could use it, thats what I would use.

I run Mobil 1 in my 4 stroke outboard and it seems to work just fine.

I have run synthetic for 5 years now in my Polaris 4 stroke and my ATV has ran great with zero problems.

I run Torco.... but remember I'm a two stroke..... I know people who run amsoil in their 2-smokers as well, but have no clue about four strokes.

All of the Amsoil Motorcycle and ATV fluids are wet clutch campatible. They won't adversly affect your clutch.
