Homelite Super XLAO Loves chain oil

We cut alot of wood with the XL12's & the SXLAO's. As far as I'm concerned there's no such thing as using too much oil on the bar. This is what protects the bar & chain from heat and wear. The problem with those saws is that the oil tank is too small and must be refilled regularly. It seems I refill ours after about 10 or 15 minutes of solid cutting. I don't let it run dry or sparks will fly off the bar. If you're using (and buying) bar oil, consider using crankcase oil, expecially from diesels--that's what we do. Haven't bought bar oil in 20+ years. Our chains "stretch" sooner than they wear out and we've only replaced one bar when a tree fell on it and bent it beyond repair. Our two bow saws were bought in 1978 and are still running with the original bows.
