amsoil/synthetic oil

Post by furnacedoc » Wed Feb 19, 2014 7:22 pm

Hello, ok I am going to open a debate on oils. Is amsoil worth the price of it or should I not use a synthetic oil in my Wing which has a wet clutch. are there any test results that are not from an oil industry or the Government.

Plenty of wet clutch compatible synth oils available.
Plenty of threads discussing oils, too.

I routinely mix at least one quart of the MC 20-50 Amsoil with Rotella 5-40 synthetic oil in my bigger bikes.
Just steer away from any oil labeled "Energy Conserving" as they have additives to make the oil more slippery such as molybdenum.
Reason why a diesel engine oil works so well as they usually have a better zinc quantity.
Some people though are claiming in very hot weather the Delo oil makes for clunky shifts, I cannot attest to hot weather, warmest I may possibly see is a couple of days in the low 80F up here in Alaska.
For the cost the synthetic Rotella T6 5-40 is the best buy, its being used by a LOT of bikers with water cooled engines.

Use the weight recommended! The Amsoil, while a good product, is overpriced, IMO.

If you use Amsoil in a wet clutch bike, make sure it is one of the motorcycle ones you use, and for wet clutch bike use. Their 10W30 and 10W40 are fine for Goldwings. The 20W50 is designed for Harleys and other air cooled engines without wet clutch, so I do not know if it is really suitable. I think not. Amsoils suggested prices aren't that bad, but dealers sometimes add a little extra to make a bit more money. Our Canadian Tire stores here in Canada carry it at $18 a quart, and that is really excessive. Normally should be between $11 and $13 a quart. I use it. I also like Rotella T6, and it is less expensive. You can save a little buying by the gallon from both Amsoil and Shell.

Just make sure the oil your are using is a Motorcycle grade oil, no friction modifiers, frictions modifiers will play hell on your wet clutch. As far as oil viscosity goes, that would depend on your climate temps, if you are living in a cold climate then you might want to choose 10W30,40,50, if you live in a warm climate such as AZ or TX you might want to go to a 20W30,40,50. The "W" in 10W30 means "winter grade". So to prevent dry start ups in cold temps you use a low viscosity number oil such as a 5,10 and as the engine reaches operating temps this oil will function like the viscosity of the second number ie; 10W40. Where I live there is no need for me to use a 5 or 10 weight oil due to the temps not really getting that cold. In my bike I run 20W50, the bike likes it just fine. I also use ZPPD in my oil, this isn't a friction modifier is just adds more zinc to the oil helps on the wear and tear of gears.
