zinc oil useage?
Penn Grade or Driven is all we use. The Cosworth motors (Ford DFV, and Ford Kent block based 4bangers) my brother builds spin up past 10,000 + RPM for 20 hours with solid OHC flat tappets, during tare-down the bearing look like new and there is times he’s tempted to reuse the bearing. All I’m saying is he has been using Penn grade for 20 plus years in these motors, never had a problem from the oil. which BTW the DFV costs 60 grand for a rebuild and 150 grand for a new one, all trusted to 10 dollar a quart oil… were more worried about a part failure than which oil to run…
