My bike had a drinking problem.
I know, it's tough to believe. No one ever wants to believe it, but the facts were staring me right in the eye: after about 2,000 miles since the last oil change the oil sight glass was no longer full of happy black bubbly. My bike was drinking oil.
So, I got out the measuring cup and started adding oil. One... two... three... four ounces; the oil was still not at the full line. Jeez!
Five, six, seven eight nine--oh my God--teneleventwelve!? My bike drank twelve ounces of oil in 2,000 miles?! Argh! This was not acceptable. Time for an intervention.
I rode about 500 miles to burn off enough oil to make room for some Auto-RX, changed the oil filter and added 5 oz of this amazing engine cleaner. This brought my oil level just a hair above full.
Since then I'd been keeping a casual eye on my oil level, and in the last 1,000 miles and it didn't look like it was going down any further, but I'd been really busy with work and hadn't taken the time to get the bike properly level and get an accurate measure. I finally took the time tonight to do an accurate measurement, and I'm happy to report that the oil level is now only a hair below full. I'm guessing it's about 1-2 oz down based on my previous measured adds.
Yea! The bike would have burned about 6 oz previously, so I'm pretty happy with the results. The 1-2 oz of oil were probably used right after I first added the Auto-RX, but before the Auto-RX could clean the rings up and help them seal completely. All this goodness and I still have 500 miles of cleaning action left to go, not to mention the rinse stage, too.
