Lets talk oil filters... OEM VS Aftermarket
Anyone else have problems with aftermarket oil filters? I was using Fram oil filters with 5-20 Valvoline oil & once temps started dropping, when started it would whine for 15 seconds & oil pressure light would stay on then would shut off & whine would stop.
I switched to a OEM oil filter & problems went away.
Comparing the OEM Vs Fram was a difference. Fram was smaller, didn't look like it could handle vs OEM. I noticed it ran better on OEM. Iv6e been using OEM for over a year & the problems haven't came back.
I have switched over to 5-20w Castrol GTX Magnetic. Pleased with results. My brother who owns a trailblazer switched over to Royal Purple & swears by it but feeling how thin it is & reading online on the battles of cons/pros of RP i wasnt switching over.
