Castrol GTX 10W-40 and Shell Rotella 15W-40 are both fine oils. There is no longer a requirement to display "oil conserving" or "energy conserving" labels on oil containers.It seems like the #1 thing I want to avoid is friction modifiers. As far as I understand, oils 10w-30 and below must state if they contain them with the "energy conserving" stamped on it. However that isn't the case with 10w-40. It seems like you really have to do your research and delve i to the product sheets. That's why I ask if you guys have any go-to brands that you know don't contain them. I'm not trying to dump money on motorcycle oil when it seems like there's no appreciable effect, but I don't want to risk using an oil that could or could not contain clutch destroying components. What recommendations have ye?
In a test, motorcycle specific oils did not perform as well as conventional oils, and they tend to cost 2-3 times as much.I like to get the oil with the little picture of the cycle on it- Castrol’s 10-40 or 20-50 😀
Shell Rotella meets JASO specs.Look for oil with Jaso MA 1/ MA 2 Specification. (Oil for use with wet-clutches.)
Oil with milky caramel colour means you got water in it. Water & oil form an emulsion . It should be changed ASAP.
The oil level is checked with the bike level and the dipstick unscrewed and resting on the threads.
