Good oils for KLR 650

Does anyone have a favorite oil? And if so, why do you think it's good? I'm using Quaker State Ultimate Durability 10w-30 full synthetic. I chose this oil because it's full synthetic and it has a high pressure rating of over 100,000 psi.

Good question, glasair!

Expect considered responses, from inmates who have extensive personal experiences with a variety of lubricants, including scientific oil analyses of different oils from at least two profound laboratories.

Owner's and service manuals disclose rather broad criteria; this forum may yield the ONE TRUE OIL (as in, the ONE TRUE RELIGION).

I'll caution you about possibly using the thinner grades of automotive oils, these days. (Energy Conserving/Resource Conserving in the roundel on the back label.)
They tend to have too much of the super slippery additives which can cause not only drive clutch slippage in wet clutch motorcycle engines, but also starter clutch slippage.
The slippery additive impregnation adds up over time, so it doesn't necessarily happen immediately. But un-contaminated KLR clutches have been know to operate over 200,000 miles.

Best to use oils with the JASO MA / MA2 or MA3 rating on the back label to ensure that it is wet clutch compatible.
Most of them are 10W40 graded or higher, but there are exceptions. Kawasaki sells a 5W40 Semi-Syn with JASO MA2 grading.
The thinner grades are also intended for continuous use in ambient air temps under 40F, not 60 - 100F which is normal motorcyclist riding temps.

Here is the oil analysis thread, https://www.klrforum.com/klr-other-m...is-thread.html

Ill bite .... What PD said above ^^^^

To shorten it, basically anything other than what you are currently using ... The 100,000 psi thing is irrelevant to a KLR which is basically 1940's technology. Buy ANY motorcycle oil or diesel oil with an MA rating and dont use car oil ... Brand largely irrelevant ..

Whatever oil you run, why not order a sampling kit from Blackstone and send a sample in? Compare the results to what others are seeing, both in Blackstone's averages for KLR650s and for what others are seeing in the oil analysis thread.

What matters is how a certain oil performs in your bike, given the way you ride, where you ride, how often, all-year, vs seasonal, etc.

Paul and I use the same oil. I found that the Kawasaki oil seemed to get better analysis than the Rotella I was using, but Paul's results with Kawasaki oil are consistently better than mine. I choose to use Kawasaki oil and simply wish that my results were as good as his; perhaps one day they will be. Perhaps the differences in our bikes and the way they are set up and used mean my results will never be as good as his.

Whatever you choose, choose it based upon facts and data and not advertising hyperbole. The only thing you will ever really know about an oil as you pour it into your engine is what is in the wee circle on the back of the bottle. Everything else is meaningless hyperbole designed to sell the oil. By testing the oil after you've used it and comparing it to other oils you will have some hard data on how it performs - in your engine.

Generation 1 Owner's Manual says:

API SE, SF, or SG
API SH, SJ, or SL with JASO MA

And:



No Kawasaki caveats on "friction modifiers," or "energy conserving."

But . . . what does Kawasaki know?

(Hope image shows cleanly; Photobucket misbehaving (again)).

I'd love to read a 3000 or 5000 mile report from your bike with your preferred engine oil, in our Oil Analysis Thread.

So far there has been Only ONE that has Significantly exceeded the performance of my chosen oil, its in the thread.
