I normally dont post in this thread just for an oil & filter change but....
I decided to switch my Vstar 650 from Walmart generic blue bottle $2.50 per quart 10W40 to Mobil One synthetic 10W40 (not the one in the motorcycle bottles for $2 more, the 5 gallon container for $22 at walmart in the car section). I made sure there were no mileage enhancers (bottom half of SAE lollypop is blank).
The bike just hit 43k miles and it was due for oil and filter change.
The real reason Im posting this breaking news is: the bike sounds quieter to me, esp when idling, it seems to be running smoother
and it actually does seem to shift easier.
Not that there was ever any problem shifting before.
Maybe its just the placebo effect from paying more than twice as much for Mobile 1 than the SuperTech walmart brand name stuff, but I think Im going to have to change the oil in my Royal Star now to Mobile 1 (early, its not due for a couple thousand miles) to see if it also runs better.
The last time I did an experiment like this was when I filled the 650 with ethanol free regular gas. It immediately seems to be running a little stronger which is not surprising, because removing the 10% ethanol will make the bike run a bit richer, but I got exactly the same fuel economy, so that might also have been purely the expectation of improvement influencing my subjective observations.
