Not much to say, been using Mystik JT8 SEMI SYN GAS/DIESEL HEDO 15w50 for quite some time now and still getting the same better then good results. This recent oil has seen some rare but actual measured temperatures with my digital dipstick in the upper 260s and peaks in the mid 270s during some near 100 degree weather stopped in traffic. Not a big deal but the highest I ever measured. Normal high speed temperatures are not unusual on long trips, 2up, 80 MPH in the 250 degree range on super hot days, recent high speed trip was 257 degrees coming home from the mountains. Anyway, all is good, oil can take it. Harley states normal as 230 so the temps are not too high. I do now have a Lenale engine cooling fan and saw in actual use once its turned on engine oil stabilized and went down slightly. Im not promoting cooling fans, engine and oil is made for heat. I do this stuff for fun projects and I like the look of the new Lenale much better then the horn cover :o) Reports on 7/19/15 and 6/8/15 are Harley Conventional oil. Reports on 12/12/15, 8/7/16 and 7/29/17 are Mystik JT8 15w50. I am experimenting with a new oil, Mystik will always be my go to oil and I have GALLONS of it purchased. For fun I am running an experiment on another oil that I just put in. I will post UOA late fall, plan on doing 2 runs with it and then back to Mystik. Reasons for the experiment have nothing to do with Mystik, its performing great, reasons have do to with additive pack vs "film strength" .. which will be explained late fall.
