I was wondering if any of you recommend using Mobil 1 or other synthetic oils in your Versys?
unless the owners manuel calls for it ,no, I run it in my Triumph as it calls for it , but use Valvoline or Pennzoil MC oil in my Versys,it is more than up to doing the job.Ps this thread is gonna get like all other oil threads so i will not return :blah:I was wondering if any of you recommend using Mobil 1 or other synthetic oils in your Versys?
:thumb:My experience has been if you use a good quuality petroleum based oil (i.e. GTX, Valvoline, etc) and change your oil every 3000 miles, you'll be just fine. The synthetics are good oils to use if you are going to run the snot out of the bike or are in an area of extreme heat. Just my 2 cents.
Only engine oils of up to W-30 viscosity can be energy conserving rated. Friction modifiers which are not wet clutch compatible are still found in some automotive W-40 and higher viscosity oils. Motorcycle specific oils are JASO MA certified for high friction applications, as recommended by Kawasaki.I use Castrol Synthetic 5-40 automotive because I bought a bunch on sale for my VW diesel. Basically any automotive oil will work as long as it does not have the energy saving logo on the bottle. The friction modifiers they add to make it "energy saving" don't work well with the wet clutch most bikes have.

From Castrol; "Note: The low friction characteristics of Castrol Edge 0W-40 make it unsuitable for most motorcycles that incorporate wet clutches in combined engine and transmission systems. Castrol’s prime recommendation for this application is Castrol R4 Superbike."
"Castrol does not recommend using automotive oils in motorcycles. In 1996, the American Petroleum Institute (API) upgraded the performance standards of automotive oil from SG to SJ (currently SM). This upgrade impacted the friction modifiers and zinc and phosphorus levels, to address the fuel economy, catalytic converter and pollution issues of passenger car owners. For motorcycles, the additional friction modifiers can affect wet clutch performance, and motorcycle engines appreciate a higher level of the anti-wear ingredients of zinc and phosphorus. We have formulated our line of Castrol Motorcycle oils to be API SG. This allows us to optimize the formula specifically for motorcycles without being constrained by the specification demands for passenger car engines, which our passenger car oil must meet. All Castrol Motorcycle oils have low volatility to reduce the effects of oil evaporation, and they can be up to 50% lower than many API SL/SJ passenger car engine oils. API SJ engine oils have a minimal shear stability requirement; therefore, some types may lose their viscosity more quickly when used in a motorcycle, due to the stresses of these bike engines."
There's also Shell's excellent Rotella T6 synthetic 5W-40 that's available for less as it's not JASO MA labeled, but still passes the tests. According to Richard Moore, Staff Engineer at Shell Global Solutions (US) Inc., Westhollow Technology Center, Houston, TX (800-231-6950):
"We recently ran the JASO MA friction test on Rotella T with Triple Protection 15W-40, Rotella T Synthetic 5W-40 (CI-4, discontinued) and our Rotella T6 Synthetic 5W-40 CJ-4. All three oils passed the wet clutch friction test. Rotella T Synthetic 5W-40 (CI-4) has more than 1.2% ash (JASO MA spec limit) so it can not be classified as JASO MA. However, Rotella T with Triple Protection 15W-40 and our Rotella T6 Synthetic 5W-40 CJ-4 do meet JASO MA."
Shell's Rotella T5 semi-synthetic is also a good choice.
