I would if I could get it cheaper than Fram Endurance. I think I paid $12 for this filter, which was cheaper than the endurance at the time. They have now went up on these, to $17. As for the filtering I still like these, even with the waves. I’ve inspected quite a few of these with low miles...

I didn’t change the oil, so it is still Mobil 15W-50. Oil filter is Carquest Premium 85515

Same stuff. Mobil 1 ESP 5w30 and Carquest premium filter.

Yes, straight up. It’s kinda shielded so that’s why I didn’t see the dirty side.

Yes, just that one area, maybe 1/4 of the filter. I honestly didn’t notice it until I went to cut it open, so I’m not sure what direction it was on the engine… I know the bottom of the filter was clean, because I looked up at the filter before removing it.

I hadn’t seen that. However there is no way it wasn’t tight. I installed it the same way I’ve installed all the previous premium guard filters. Seat them and tighten them down tight by hand. Not that I have a super grip but it takes a decent filter wrench to get them off. I actually wondered if...

Really hard to tell, when I removed the filter oil pours out over that area.

Agree. Seems like most companies are going away from them. I believe most of the Napa gold filters are premium guard or someone else now too.

After my Mobil (M&H) filter experience, I’ll pass for anything with the name Mobil or M&H…

It’s a Hyundai so every time it starts it’s severe, right… the first engine in this car became an oil guzzler, 2 quarts every 1,000 miles and that was on 5-7.5k mile oil changes. It may not help, but I’m not pushing those again. Normally, I will be changing the oil at 3-3.5k and the filter...

Premium guard extended life PG4459EX from the 2015 Hyundai Sonata. Replacement engine has ~13,000 miles, filter and oil has ~3,500 miles. Out Mobil EP 5w30 and PG4459EX In Mobil 1 ESP 5w30 and Carquest premium 85334 filter

Again it isn’t any different from any other oil, in terms of mixing. All oils have to be compatible to mix. There isn’t some gel that is going to form. Mixing two high quality oils, will still be a high quality oil. Mixing viscosity also doesn’t matter in terms of gelling or some chemical...

Can you point to where it says it’s formulated to blend with any oil? I don’t think it is anything special for blending. I think the only reason they tell you to blend it is the fact it will clean to much to run full strength on the first oil change. it’s really not an issue. Many shops use vac...
