So I bought my bike 3 weeks ago now (from a Triumph dealer) and the oil when I bought it was all the way up to the top of the sight glass. I figured I would change the oil and filter to stop the leaking. I got half way through putting in the new oil and noticed I had bought Valvoline 10W-40 motorcycle oil, but it does not say anything about it being synthetic, DAMN IT! Do I have to drain this oil and start over?? Can I run this bike awhile with this oil so the wife won't kill me for "spending more damn $$$ on the bike!"
