Jun 3, 2026

There has been a lot of confusion on who makes the new Mobil 1 Extended Performance oil filters. Many think it's made by Premium Guard Inc (PGI) because the construction looks the same as many PGI made filters. I sent a message to Highline Warren asking them if PGI is involved with the Mobil 1 oil filter, and this was their answer. Highline Warren and PGI are not connected to each other.
