1986 Kawasaki Bayou 300 Synthetic Engine Oil

[mmgood]

Hey people

Question for all, just picked a 1986 bayou 300 thinking of going synthetic any thoughts ?

[BradCad]

Always! I run synthetic in everything I own. Even my old antique engines. It wont fix anything but it wont hurt anything for sure.

semy synthetic is a better choice for older machines

[Kevin Jackson]

Either is fine as long as it’s motorcycle/atv oil for wet clutch 

[Frank Angerano]

The only differences between syn/conventional is the viscosity break down.  Bottom line syntheyic will hold up Better, longer etc. Can’t hurt. Only thing I can recommend is once you put it in stick with it until the end !

The only thing I've found is that synthetics will reveal any oil leaks, even those that may not be visible with conventional oil.  I think it is due to the smaller molecular structure.

Synthetic is so much better in long run

I agree with carguydave, I'm using 20wx50w Valvoline full synthetic in my 2001 350 4x4 Yamaha Wolverine. I had no oil leaks the first 3 months I owned the ATV, (acquired the unit in 2016), before I changed to full synthetic, now my cylinder head on the left side has a film of oil from top to bottom. ATV runs great sounds great, and I'm still glad I have full synthetic in my machine. But depending on how old your machine is, it may develop some unsightly leaks.

I've ran Rotella diesel oil in several motorcycles and quads with good results.

I agree with Frank Angerano on this one.
