Is it the govmt or is it Detroit and the oil companies trying to save money? Detroit dictates the spec of oil they want for their motors.
Virtually all newer stuff use the lower friction roller lifters and dont need the scuff protection of zinc (oil companies aint gonna give you nothing they dont have to--like 16 cent gasoline with lead).
I feel us hobbiests have no lobbiests therefore no hope or help from Washington, or Pennsilvania for that matter.
Now I'll step down from my soapbox -thank you.
