Review on 🔴 Ultimate Performance with Royal Purple 40-780 Oil Filter by Tommy Russo

Bought to match my Valvoline Premium Blue Synthetic 5W40 on my 6.7 CUMMINS HO (all emissions in tact at the moment). Screwed on well and the "O-ring" seems to seal well. I haven't noticed any oil residue or leaks around the gasket or filter housing after about 1000 miles. Update: 6,500,000 miles on this oil change in all different conditions and the filter seems perfectly clean. No oil residue or leaks on the canister wall. Very happy. I will be draining the oil and taking an oil sample from the CAT over the next few weeks. That will tell me how well the filter is working. I will post the results.
