Hey whats up everybody?? I'm going to be getting a new R6 within the next month..i'm trying to factor in the cost of maintenance and what not with my monthly payments..I used to ride motocross and i had an 01 yz250F..i always used Rotella in that bike and it worked awesome..i rode the [censored] out of that thing for 3 years and sold it with the original clutch..Now if i get an R6, i was going to use Rotella in it..but to be honest, i'm going to change the oil every 3-4K miles..So it wont kill me to spend the extra money on the Amsoil..My main concern with using the Rotella is that since its not a motorcycle specific oil, that they may change the chemistry of the oil suddenly, and than it may not be suitable to use in a motorcycle..Is that a dumb thing to worry about? I just really want to pick an oil and be able to stick with it for the time that i own the bike..The R6 holds 2.75qts with a filter change, and yamaha recommends changing the oil every 4K miles, with filter changes every 8K miles.. I'll be doing probably 3 or 4K change intervals and changing the filter everytime. Alright well thanks for any advice you guys can give me..
