Originally known as Kendall and then Brad Penn in the early days, PennGrade 1 Motor Oil was renamed when acquired by D-A Lubricant Company in 2015. No matter what name it carries, PennGrade 1 Motor Oil has (and always will) be about the perfect balance. Whether your vehicle only sees the everyday demands on the road, is used as a race car (officially, or not!), or just good old- fashioned hard driving, PennGrade 1 Motor Oil provides the right protection.
PennGrade 1 Motor Oils contain high levels of zinc that provide enhanced anti-wear and anti-scuffing protection, especially in flat tappet or roller type cams. However, because of the high zinc and phosphorus additive concentration levels, PennGrade 1 Motor Oils can be detrimental to cars and trucks with catalytic converters. PennGrade 1 Motor Oils are recommended for vehicles manufactured prior to 1975 WITHOUT catalytic converters. Be sure to check your vehicle’s owner manual for proper oil selection.
