[QUOTE="ionbeam, post: 1236365, member: 277"] Since this thread now has oil information in addition to tips for trip oil changes I'll add something here. High Mileage oil normally contains seal swelling agents which helps CAR engines with crank seals and valve stem seals. It is worth noting that the original Gen I engines had some rare instances of excessive valve guide wear causing the valve stems to rattle in the worn guides (Forum named "Tickers"). The root cause was valve stem seals that were too tight and starved the valve guides of oil lubrication. The fix was for Yamaha to install slightly looser stem seals. I'm not sure that a seal swelling oil would be a good thing. Just an observation, we are big boys and can make our own decisions. If you start the trip with any name brand oil and a new oil filter there should be no problem going 7.5k miles. Motorcycle engines share the oil with the transmission which does shear the oil's polymer chains causing oil which goes in like syrup to go out like water. Synthetic oils take heat better than pure mineral based oil. Most brand name oil's additive package should be good for at least 7.5k miles. An air filter that lets in fine grit is probably more harmful than an extended oil change. [/QUOTE]
