Review on Royal Purple 50 2017 Oil Filter by Jarom Bulles

Revainrating 3 out of 5

Check valve defective at 5,000 km.

Anti-drain valve broken after 5K. I run 10k for an oil change on Royal Purple 15-40, get honey and smooth. The need to change the oil filter in the middle of the oil life due to dry starting, fortunately the oil is so good that it does not wear out even when dry.

Pros
  • Excellent design
Cons
  • Compatibility
