have tried 1 oil change with amsoil, am contemplating the next w/T6 seeing i use it all the other
motors except cars. the ? to you guys[and gals] that are running it-how many miles are you
going between oil changes? any input would be appreciated. thank you!!--irv tomsopcorn:
im an advocate for early change- mobil1 in motor vehicles changed between
3-4000 miles. the t6 in everthing else always done way early. but i see amsoil people
running 9000 miles, but the rotella people only half that mileage. dont trust it to go
farther? never have tested oil in 54 miles of driving. maybe ill try it. pure economics
say changing t6 twice as many times im still ahead. or am i?:gaah:
To the OP, do you have your oil analyzed? That's the only real way to tell how it's performing. My last analysis of Amsoil Metric 10W-40 fully synthetic at 9,300 miles showed the cSt 100C at 13.8, hands down better than Mobil 1 4T Racing at 6,100 miles. The Amsoil has proven best at the least viscosity shear-down of the three oils I've used including the Mobil 1 and BRP XPS synthetic blend.
Rotella is an oil designed for a heavy duty diesel engine. Do you think they change it at 5K miles? Not being a truck driver, I would only have to assume that they change it at extended intervals. Changing oil on short intervals is just an unneeded precaution.
Irvin48....see post #2. Keep in mind that was in an air cooled engine that is harder on oil by running it hotter at times. Therefore, T-6 is easily a 9K oil in liquid cooled engines..
Sadly, an oil analysis does not represent lubricity. Yes, it measures viscosity and contaminents.
When choosing suspension fluids, like oil for an engine, factors do play into it. One is VI or viscosity index. The oils you mentioned have published VI numbers. What I have learned and experienced is that the suspension fluids that offer the best VI numbers do last a long time, however, they also provide the worst lubrication, which can be felt by the rider as stiction or notchy suspension movement.
Having done countless oil analysis samples on aircraft engines over the past decades, the best information tends to be contamination of the oil, and less about viscosity. Contaminated oil is obviously bad, and causes wear. Poor lubricity causes wear.
I ran BRP oil for break in distance. I replaced that oil well ahead of the scheduled interval. Immediately the gearbox shifted smoother but was still somewhat notchy or tight. After break in, when I went with my current oil, almost immediately, the gearbox freed up. My point is even with new oil that has not sheared, lubricity triumphs over VI.
I have never done oil analysis on the Spyder and have no plans to. I run a premium oil, changed each 5000 miles which is approximately every 12 months.
didnt realize i had 1 oil change worth of brp oil here. used it friday. either amsoil again or rotella next change.
will only go about 7-7500 miles on it. thats what i did for my first change back in '16. thanks for all the input.
