Castrol 4 stroke 20-50 motorcycle engine oil
My bike is a 1991 FXSTS ( I know this not the sioftail site ,but there's more people on here )
Today I was at the auto store buying oil . I always buy castrol 20-50 4 stroke motorcycle engine oil, but today I noticed the picture on the container was that of a crotch rocket bike , very likely liquid cooled .
Would the one oil be designed for both liquid cooled and air cooled motorcycle engines ?
Since they dont mention either on their website ,or container the oil is probably to be used in both .
Can anyone give me any information ?
Thanks , Neil

Rice bike oil is usually JASO MA or similarly rated, low molybdenum content so it does not muck up a wet clutch
What you are looking for is something with high zinc to keep the cams happy
Is this what you saw? It says on the website good for high heat air cooled engines,
personally I'd use the stuff in the second link I posted below

There`s probably some guy on a Kawasaki forum worried about using this oil because he thinks the drawing looks like a Honda...
It`s a drawing of a motorcycle on an oil bottle, to depict the fact that they sell it as motorcycle oil...
You are way over analyzing this...
The Castrol will work fine.

Every one of the numerous owners manuals Ive had recommended a specific Diesel rating compliance 20W50 oil which the original H D oil has!
I still use this on all my older Harleys,but switched to Syn 3 on the Milwaukees.
