I have a 06' Eiger and I've been running suzuki oil in it so far but I was thinking about changing to a synthetic oil. Does anyone have a suggestion for a good synthetic oil?

 

I RUN THE SUZUKI OIL IN MINE ALSO BUT I WILL MOST LIKELY BE SWITCHING TO AMS OIL FOR ATVS \4 STROKES ETC MY POLARIS USES A O WEIGHT 40 THATS WHAT IT CAME WITH I SWITCHED MY SONS HONDA TO THE 10 40 SYN OIL JUST MAKE SURE IT IS "WET CLUTCH COMPATABLE" IF I SPELLED THAT RIGHT. ON YOUR OIL FILTERS I FOUND THE CROSS REF FOR THE FRAM OIL FILTER IT WILL SAVE YOU ABOUT 5 DOLLARS A FILTER . RATHER THEN BUYING THEM FROM THE DEALER...

 

I use Amsoil and like it. It quited the Eiger motor down a little bit and it feels like it runs a little cooler (not so hot on the legs now).

 

I put Amsoil 0-40 in my Eiger and it runs cooler, and the gears shift easier. Seems like good stuff.

 

Rotella 5w40 synthetic makes mine run cooler as well.
