How long can full synthetic oil last in a bike that hasn't been ridden much?
Last year around this time I changed the oil and filter on my '02 750 using full synthetic Silkolene. I then proceeded to ride about 8 times over the whole rest of the year thanks to a heavy work schedule and a lack of people to ride with on my few days off. Those rides only totaled about 300-500 miles.
I've now gone an bought the materials for this year's first oil change, only to notice that the oil in the level window is still almost the same color and consistency as the day I put it in. So the question is this: Since I used full synth (and have been for a few years now), hardly rode the bike at all last year, the oil doesn't seem to be showing any wear, and it's been in a garage protected from the elements the whole time, could I put off this oil change for a little while to get more out of my nearly $100 investment last year?
