Description
Three color 5″ x 13 1/2″ ad for their Piston Rings. The ad pictures the three Bad Guys: Oil Waste, Gas Waste and Engine Failure and claims that installing these rings can reduce or prevent these disasters from happening in your car. The text calls this “The best ring for Oil Control even in Badly Tapered and Out-of-Round Cylinders.”. It then says that the Sealed Power MD-50 Steel Oil Ring is “the only ring with FULL-FLOW SPRING” and issues the challenge that “No other ring equals the Sealed Power MD-50 Steel Oil Ring when it comes to controlling oil consumption in badly tapered and out-of-round cylinders”.
