I just bought some amsoil 0w40 synthetic for use in my Eiger. Just wondering if anyone else uses there products and there impressions of it.

 

Ive used alot of different products from amsoil, never had a problem or issue with any of them.
Im not sure id use the 0w weight oils though...the service and shop manuals dont ok their use, at least on my quads...the minimum ratings are 10w for almost all air cooled motors. And even if they were water cooled, i dont think id use 0w oil.
Mine start just fine down to 10F, as long as the oil is synthetic. I use 10w 40 synthetic, in the winter and regular oil in the summer.

 

actually the 0w-40 covers the 10w40, atleast that what it says on the back of the bottle. I've used amsoil in my quads for ever and will use nothing else, (eccept during breakin). my o' 89 Lt250S has never givin me a bit of trouble and recently I checked the clutch plates just outa curiosity and they looked and measured like new and they are the factorys. That goes to show how well amsoil works in these bikes!!

 

yes i use 0w40 Amsoil in the winter in my Eiger...it made it shift a lot better (smoother) and the 0w rating got it warmed up faster

 

Amsoil and Mobil 1 are PAO synthetics. PAO's have many advantages over petroleum oils, but ester synthetics have advantages over the PAO's. My pick is Maxima Extra or Ultra.
