First I have searched and read not only all I found on klr oil burning issues, but have read about other bike burning oil as well. I have a 2011 with 6600+ miles on it. I have the caribou luggage system as well as the appropriate offroad and crash protection. I'm on a trip from Colorado. With a stop in Tucson to meet my grandfather I noticed next to no oil in the site glass. I did battle head and cross winds most of the way through New Mexico and had on several occations the throttle wide open just to maintain the speed limit. So I let it cool as much as I could over night and ended up adding 2/3 of a quart to bring it up to the appropriate level. Set out to make the final trek to California. Once arriving on the 3rd, having spent 11+ hours in the saddle with LA all the way to Malibu equalling 1-1/2 hours of stop and go traffic. I again saw very little oil in the site glass. I then added the remaining 1/3 of a quart and it brought the lever to a little above half in the sight glass. Now the question. Is this an acceptable amount of oil consumption. 1400+ miles and over a quart burned? I have been running Mobil 1 10-40 motorcycle oil and changed oil every 2000-3000 miles. But if if it's just gonna burn it away wouldn't it be better to run conventional oil? I have owned the bike since new and tried to adhere to proper break in and changing frequencies. I had up till this trip used the bike for commuting and small trips around Colorado. Is there a reason synthetic would be better in this instance? $11 a quart vs $3 or so. I'm used to using synthetic in my cars and trucks but never had to add between changes. Thanks for the input.
