Any one interested in the oiling mods I did?
I agree...oils have made tremendous advances. I used to run 20-50 in all my engines, now I have gone to 10-40 or 10-30.
When people talk about how long engines last now, it's always attributed to 'modern machining and QA', and it's usually accompanied by some sort of slur against older engines. The fact is....oils have been far more to thank than any other single factor.
