Re: Oil ratio for a Scott Atwater 16

[kerry]

Listen to Pappy. Its not the quality of oil, its the QUANTITY you need. Tolerances were larger back then, because that was what their machinery was capable of. No CNC, robotic, laser, etc. Quantity of oil was needed to keep metal from hitting metal. Synthetics keep a film of oil on parts better than conventionals, but I would not lean the ratio too much. Pennz full synth is around $27 a gallon near me, I believe the low smoke and 100% biodegradable are worth it.

If you have too many, AND not enough, you're a collector.
