At what mileage should you switch to synthetic oil and transfluid? I know an engine needs to run on regular oil for a certain amount of time to get a good ring seal. But can the trans fluid be changed sooner? | ||

Get ready for a lot of mixed replys. Some will tell you right away & some will say wait till you get at least 5K miles. I being old school (despite my wee 35 yrs of life) am waiting for the 5K mark to switch the crankcase to syn. I'll be switching the primary to syn at the 2500 mark. I remember long ago a friend who was phenominal with engines telling me that it was best to use dino oil till the engine was fully worn in cause the irregular shaped molecules of dino was better for ring cutting than the exact duplicate shaped molecules of synthetic. I dunno how accurate that statement is but he never had a bad engine in all the years I've known him. | ||

I think 1k is plenty, 500 miles is the break in period. And since 1k is the first oil change might as well change it to synthetic. | ||

My 12R just passed 6K and I recently changed to syn all around. WHat a difference. Shifts like a different bike and my fan said "ahhhhhhh, thanks for the break." I can't find Mobile 1 around here so I went with the Harley stuff, seems to be working good enough for me. | ||

stroke is 3.8125 inchesx2strokes (up,down) per revolution x3000 rpm (thats 65 miles per hour in top gear)divide by twelve (inches per foot)=1906 feet per minute of piston travel. times 60 minutes, divided by 5280 feet per mile=21.6 MILES of piston sliding up and down the bore per hour on the highway. consider actually dragging a piece of piston ring across a freshly honed cross-hatch. for a minute. now consider dragging a piston ring across 21 miles of freshly honed cross hatch. okay, get my point? ran your bike for an hour? your rings are seated, you can drain the oil any time now, might consider a fresh filter about now too. dont be too scared of synthetic oil. it costs more but does not contain magic. lubrication properties yes, magic-no. there aint no such thing as "too slippery" | ||

These manufacturers fill their vehicles with synthetic oil from the factory according to Mobil 1 website. If there is a problem using synthetic lubrication in a brand new engine, why would these guys do it? Manufacturers' Choice Mobil 1® is standard equipment in some of the world’s finest production vehicles. Car manufacturers rely on Mobil 1 motor oil for the first oil in a new car, otherwise known as “factory fill.” Mobil 1 is factory fill in: Aston Martin Bentley Amage and Bentley GT Cadillac CTS, XLR, SRX and STS Chevrolet Corvette Dodge Viper Mercedes-Benz AMG vehicles Mercedes SLR Mitsubishi EVO Pontiac GTO All Porsche vehicles Keith | ||

I agree 110% with Fullpower! After 1 hour of running, the fresh cross-hatch has become rounded over and the rings are as seated as they're ever going to be! I switched everything over to synthetic at the 1k service, and noticed an improvement in the way the bike runs and the fan doesn't come on as often. | ||

If the weather holds out I should be just over 500 miles by the weekend. I'll be changing the fluids to mobil 1 on the weekend. I'd just like to give a thanks to everyone who has posted. | ||

I switched at 1000 miles in engine. Trans got switched at 250 miles. Works like a charm. Mobil 1 in both. |
