Well, darn it! 11/6/2020 Mobil1 15/50 - ALL other dates Mystik JT8 15/50 Diesel rated oil
As a one time experiment I tried Mobil1 15w50 as an experiment to see if a full syn would actually run at a lower oil temperature. At first I thought there maybe some reasoning based on other posts I have read but I have not been able to generate that result within any margin of error. Granted, the oil I was testing it against was a semi syn (not a full conventional) Mystik JT8 15/50 Diesel oil which I have been using exclusively until this one time test.
The Mobil 1 is a little off script in Harleys recommendation to use a CH4+ diesel oil if Harley oil is not available (and to switch back once their oil is available.) The Mobil 1 is only mentioned as a CF by Mobil.
I am in shock how low the wear was with the Mobil as the JT8 was already producing low wear numbers, granted I did not get many miles on the oil this summer but still did my run to the Smoky Mountains for a week, two up, loaded with luggage and a couple trips to the beach where the oil really heated up in traffic.
We always do a lot of interstate running 70-80 Mph GPS.
Im almost tempted to continue with Mobil 1 but I just ordered and received another 4 gallons of Mystik JT8 15/50. I did think the engine sounded a little more noisy with the Mobil and was looking forward to going back to the Mystik JT8. But, that is subjective.
The miles are low on the Mobil1 oil and it did shear down a bit for that mileage, my riding time has been limited by a new to us boat that my wife bought last year *L*
