I would imagine it's gf5, remember this oil was put in the car a while ago, in this case June of 2020. So, the oil that was sampled had been in the car 18 months. Was GF6 oil commonly available back then?

I went back out to the garage after you wrote this and found a couple PBL 14610's as well as 2 PBL 12222 filters - I guess I didn't get those on Amazon since I had looked already. Looks I'm set for my oil change this weekend.

I used the ACDelco Specialty Ultraguard Oil Filter specd for the Z06/LS7. UPF48R. I'm considering the Purolator Boss PBL 14610 but I can't remember if it fits, or is appropriate for this engine. I have a few of those sitting around for my motorcycles. For the mileage it was about 17 months...

I'm not as knowledgeable as most people on here, but my understanding is the wider the range, the more VI improvers and less lubricant - or something to that effect. For days I researched what oil to put into my new-to-me Vette two years ago and settled on this. Plus, Chevy calls for a 5w-30 and...

It's been awhile since I've posted on here, just thought someone else might appreciate this. This engine holds 10.5 qts and I expected I could run this oil a long time and I was right. Also, this is my daily driver. I'll be sticking with this oil. Adding a picture of the car 'cus that's what...

Thanks guys. I too decided on a Fram ultra if I don't get a replacement for my M1 filter.

Hey guys, I installed a Mobil 1 EP filter on my 2003 Mustang V8 a few weeks ago and noticed right away that the drain-back valve is junk. Any time the car sits for about 24 hours or more, upon start-up I hear those knocking sounds that I've only EVER heard right after an oil change. I've been...

Originally Posted By: hisilver How do you plan to get an oil sample for the analysis at 7-8k? To clarify, I was originally talking about installing the valve in the next week or two but would still need to wait 10k more miles before my UOA. Then at 10k miles and using the quik valve: put car on...

Originally Posted By: HangFire About 2, install the drain plug at mid-OCI UOA time, and do a "clean catch" of oil from the stream coming out of the engine before it hits the plastic pan. I think we're alike, we know something "shouldn't matter" but get all OCD about it anyway... which means...

Hi guys, I searched for some answers regarding this but didn't find anything related. I JUST changed my oil using Mobil 1 10w30 Extended Performance and their EP filter. I am planning to change the oil once a year, which should be about 13k miles. I plan on getting the oil tested at about 7 to 8...
