It turns out I had a lot less than 700 miles to go. I hit my target mileage and sent in the sample of Rotella T6. It started as a 5W-40, but degraded to an ?W-30 over 3000 miles. This stuff rocked in terms of final viscosity in my truck. It degraded more in the 1125, as expected, but the wear metals certainly don't look bad. I'll probably try Rotella T 15W-40 next. The updated results are on my page.

What I don't understand is why people use oil that does not have the additives you need in a motorcycle that has a trans.Do we put motor oil in our standard auto trans in a Harley(spit)Trans.IMO

Mhpalin, if you're referring to my experimentation, note that Rotella and Rotella T6 are both JASO MA certified. That means they are certified for use in motorcycles with wet clutches and integral transmissions. Compare the used oil sample result against the two other motorcycle-marketed oils I've tested so far. The additive levels are not radically different. |

Yeah everyone I know who runs the Rotella runs the 14-40. Thanks for sharing! |

Unless you know more than the guy that designed the engine, you need to run the recommended viscosity in the manual and oil is high tech stuff. The biggest issue for the folks here is clutch dust contamination of the oil and whatever you run, change it and the filter often. Remember, not all oils are compatible to these clutches. The wrong oil can induce clutch slippage further aggravating this contamination issue. The advantage of using a synthetic is their ability to maintain their viscosity over a wider oil temperature range and unless you have installed an oil temp gage, you haven't got a clue what going on there. Oil temp is not the same as cooling water temp.
As some has mentioned, at speed the engine runs cooler, the air box runs cooler, but the oil will run hotter. |
