Talk:What Motor Oil Should You Use?

Definitely a good course of action to say use the manual as a starting point. I'm not sure enough of this to add it to the article but I believe that the friction additives the article mentions aren't necessarily an issue with lower grade oils. I think it is possible they weren't added until the SJ specification? Quite a few Japanese motorcycles will say in the OEM service manual that anything above SE is okay, but will read "SJ with JASO MA". That's what leads me to believe the friction additive wasn't added until SJ. --Budlight 08:44, 13 March 2007 (CDT)

Example of said specifications from a 2004 Kawasaki ZX1000-C2 Manual Excerpt

Interesting. I'll have to research that more later. --Pi3832 09:04, 13 March 2007 (CDT)
If you get a chance to eye-ball some Kawachem motor oil, can you check what API grade and/or JASO grade it is? I'm curious if their own oil meets those specs. Yamalube doesn't appear to be JASO certified. --Pi3832 11:57, 13 March 2007 (CDT)
Ok, I haven't checked an actual bottle. but Kawasaki Service Bulletin - ENGINE AND TRANSMISSION OIL RECOMMENDATIONS--Budlight 14:01, 13 March 2007 (CDT)
Very interesting. I'm not sure where to further research that move to JASO grades. --Pi3832 14:24, 13 March 2007 (CDT)
It would be excellent if we could find documents like this for other manufacturers to see if Kawasaki is the exception or if this is standard. One thing I don't know anything about is oil for Harleys. I thought many of them use wet clutches. If this JASO standard is important for all Japanese bikes, then wouldn't it seem odd if Harley wanted their oil to meet a JASO (Japanese standard)? Furthermore not that Harley is the end all be all resource, but it seems like they might have an alternative view on the "Additive" since they aren't a member of JASO (I assume). --Budlight 14:37, 13 March 2007 (CDT)

Dyes and Warranties[edit source]

It occurs to me that I don't know if CycleChaos is aimed at a U.S. audience.

It is definitely a mostly U.S. site. I've started covering bikes as U.S. models first then noting any significant changes in international versions. On the Model List pages I would like to have it in parenthesis if they aren't a U.S. model. --Budlight 13:58, 13 March 2007 (CDT)

In the U.S., requiring the use of OEM motor oil in order to maintain a warranty is strictly prohibited under the Magnuson-Moss Act. Quote:

"Generally, tie-in sales provisions are not allowed. Such a provision would require a purchaser of the warranted product to buy an item or service from a particular company to use with the warranted product in order to be eligible to receive a remedy under the warranty."

Ok first, I think that does establish that they can't void the warranty in whole. Secondly, I think it might be good to actually analyze the terms of some warranties before we state that as a rule. That is an interesting law, and I can see the reason for it. It wouldn't hurt at all to do more research on this issue. One thing I would be interested in is if the law is ever applied. I definitely made a mistake putting that up without a qualifier. --Budlight 13:58, 13 March 2007 (CDT)
