Rotella

Since spring is about a month or so away I have been thinking more about the KLR.
Today at WalMart I was looking at the Rotella oils. The standard dino T4 15W40 and the full syn T6 5W40 are JASO MA certified. Does anyone know why the Semi Syn is not?
Also, for the more experienced than I , would the 5W40 be OK in warmer weather or do I need a min of 10W40?.. I'm pretty sure the 5 would be OK, but soliciting opinions anyway.
I'm confused why the semi syn is not motorcycle certified when the other two are though.

A modest proposal: E-mail Shell with your question; I'm certain you'll receive an answer!

Been there, done that, myself!

---------------------------------------------

Regardless, to the best of my knowledge and belief, you'll have an oil problem ONLY from the lack thereof! Factory recommendations/suggestions remain BROAD; basically: If it flows from a bottle or a can, fear not!

Email sent.. Hopefully they actually respond with an answer.

I have been using the T6 5W 40 in my Gold Wing for the past 50K miles without any problems. Bike shifts great and I do 8K mile oil changes per Honda. I will switch my KLR over after a few more miles.

I use Rotella T4 15W40 and buy it by the gallon (or sometimes the 5 quart jug) because it's good and "cheap" oil. I change my oil probably twice as often as most other locations due to air quality issues...and that's my dealer's standard recommendation. I can get the T4 at around $3 a quart. Having said that, I'm definitely glad to hear any issues anyone has with this oil.

The 5W and the 10W are the cold weather (W=Winter) viscosities, so I don't see what reason there would be to use a lower-than-spec (10W) viscosity. A lower "W" number would generally be called for in a colder, not warmer, environment. However, the manuals don't provide any specs of below 10W in the range tables...only 10W, up to 20W.

Still waiting to hear back from Shell as to why the T4 and T6 are JASO certified yet T5 is not. I'll probably just use the T4 as I can afford to change it almost anytime the mood strikes me. Can't believe an oil that good is priced so cheaply.

I actually question how 'good it is' (Rotella T4 15W40) or isn't for use in a unit construction motorcycle engine/transmission.

Because if I'm not mistaken the BSL Universal Averages of ppm per 2000 miles average travel are adversely affected by the popularity of its use.
Example #1,
https://www.klrforum.com/467801-post57.html

Verses the use of what I feel are Higher Quality Motorcycle Oils,
Example #2,
https://www.klrforum.com/438425-post48.html
Notice the 3000 & 5000 mileages.

Example #3,
https://www.klrforum.com/437105-post44.html
Direct comparison 2000 to 2000 mileages.


But yea I recon that it is "good enough engineering", just like the KLR.

A marked difference between the Rotella and Kawasaki oil Thanks for that.

It might not hurt to try to find more BSL reports which used the Rotella T4 15W40 or any other oils.

There is a BSL report in that thread which used one of the Mobil 1 oils 7500 miles, that even blows the Kawasaki petroleum 10W40 used in my engine out of the water!

But these are only 3 individual bikes. I wish we had access to all of the BSL reports that are used to make up the UA for KLR650's.
BSL Does Not use Abnormal reports to average into the UA. So any reports with BOLDED numbers would not affect the UA for any engine. But I for one would like to read the top 3 Highs & Lows for each type/brand of oil included in the UA for any engine of interest.

Currently, I have Motul Ester 10W40 in my KLR and have a Blackstone kit waiting for when I drain it. It needs a few hundred more miles yet though. When I get the sample tested I'll try to post up the results to see if it's actually worth $40 gallon.
