The wet clutch isnt the only concern with using car oil with the energy conserving addative package. The sprag cluth fo the starter can be prone to failure with the use of this oil. As for finding a right oil for you bike the JASO MA standard is one that seems to be industry wide accepted. I do know that my bikes seem to shift nicer on motorcycle classification oil than "car oil" Im my high heat airand oil cooled racing ducati I use Motul full ester synthetic.

I believe Amsoil is a great product.

In my opinion Amsoil products are too expensive for most people.

I do not like having Amsoil links dominate a google search on oil info.

We sure don't need someone pushing Amsoil, here, in every thread.

Nothing is possible to change regarding Google search results. Thousands of Amsoil dealers have web sites and they use different techniques to be listed, to be distinguished from others, to be chosen by the prospect.

If you really think that Amsoil is too expensive for most of people – think twice. You are saving money actually with most of Amsoil products! I have to admit that upfront expense really is higher but it shouldn’t be so difficult to make some basic calculations about cost effectiveness. And, it is not solely about saving money. It is more about better protection and better performances.

Just add -amsoil to your next search string and it should get rid of most Amsoil links.

Good advice. Thanks Paul.

I have a Honda CBR 600F3 with about 25000 miles. After reading as many posts on this topic as I could and being screwed on motorcycle oil the past 10years. I decided to add car oil to my bike it's been about 600miles since I put car motor oil into my motorcycle. 10w-40 havoline. My bike rides fantastic i see no problems. From now on I'm using no "EC" car motor oil in my bike. Forget all these people on here who are trying to sell oil. I got my oil filters on ebay and motor oil on sale. I'm happy w/ my purchase.

The gears shear regular engine oil, what you need is HDEO like Delo 400 or Delvac Super. I use either on my RC45 with excellent results.

I've got some detailed comments in my oil paper (click in signature) towards the latter part..... But in the end, for a good motorcycle, I'd use two products.
