I noticed the owners manual calls for the UPF63R oil filter. I'm going to do my own oil changes. I stopped by two different dealerships and both dont sell the filter. They told me they just throw a different filter on when doing oil changes because they dont have the right one in stock. Just thought I give you guys a heads up. I'm just going to order a couple of them from rock auto so I have the "Correct" filter according to the manual.

ADA.ACE1... I use the AC Delco PF63 oil filter... it is easy find.. .same filter as my 2018 Silverado 6.2l... even my 2010 Silverado 5.3. There is a web site for oil filter conversions... Oil filter cross reference
I order my filter by the case from RockAuto... makes it a pretty cheap oil change... CAD $4.13ea The Deal wants $12 each...
I run nothing but synthetic oil.. . easy to find deals
Also,
I put a small, rare earth magnet on the bottom of the outside of the oil filter to contain small metal particles in the filter.
enjoy

Yea but the upr filter is higher quality and also recomend as the correct filter in my manual. 6 bucks on rock auto. That website does not list upf63r or a replacement filter. The filters are different, ones inside is made of plastic, other one very heavy and made of metal.

Just bought a new RS. I took a photo of the factory oil filter.

It’s a PF-63. I have this same engine in a 2016 Impala also using a PF-63. Based on what they actually installed on the vehicle from the factory I’m going to use the PF-63s. I don’t care what they put in the owner’s manual it obviously isn’t too important.

I just did an oil change on the wifes Camaro 3.6. The owners manual states PF63E which is what I put on. I just bought a 2020 Blazer RS and the book says UPF63R.

What is the difference between these two filters? I'd like to consolidated and just use whichever is better.

The UPF filter is a thicker gauge material on the filter can which is required to keep it from bursting because the 3.6 blazer engine has a high pressure oil pump

A guy told me the Mobil 1 filter #M1-212A is a better filter to use on my 3.6 Blazer than the Delco one. Anybody else using that one? I've used the Mobil 1 filters on my Audi for many years and they seem pretty high quality.

A guy…lol…GM spends millions to engineer these components….if you want to risk your filter exploding then by all means listen to the guy.

Mobil 1 filters are quite high quality. I suspect they are better than Delco. I never had a Mobil 1 filter "explode" on my Audi or Corvette. I wish GM's engineers would have done a better job and not released the terrible 2.4 Ecotech on us. What a piece of crap that is.

like i said earlier in this thread, the Delco has a thicker canister, an improvement over the PF63E and i'm sure thicker than the Mobil1...they changed it because the PF63E canister was failing due to the high pressure oil pump....but go ahead and do what you want...i'm only trying to get the info out there

How high of an oil pressure are we talking here? I haven't heard of oil filters bursting or that 3.6s have high oil pressure (then again I can't find much info on oil pressure on the 3.6Ls). Even a relatively thin gauge can should be able to take a good amount of pressure. I would expect the seal to blow out well before the can.

btw, I run Mobile-1s on all my vehicles without issues. I measured the diameter of the Mobile1 filter on our 3.6L '21 Blazer, with about 5k miles on the filter, and its exactly the same diameter as an unused filter I have on my spare parts shelf. No bloating or deformation of any kind. So I think running a Mobile-1 is fine.

But in the end, run whatever filter makes you happy (assuming it is in spec for your motor). Its your ride after all. Just sayin'...

I agree petrock. Run whatever you want. I feel Mobil 1 filters are quite high quality. I recently compared the UPF63R to the Mobil 1 #M1-212A (spec for the 3.6 in the Blazer). I didn't cut them open because I don't have enough money for that. Both filters are quite heavy duty sidewalls/metal can. I tried squeezing them and they both won't give. I took some pictures of them.

I like the fit & finish better on the Mobil 1. It seems higher quality. Shows up pretty good in that last picture side by side. I know the Delco looks bigger diameter but that is just the picture. The gaskets match up exactly the same diameter. Must be the combination of the slightly taller Delco and my camera angle. Yes, the Delco is slightly taller. Not enough to allow more oil capacity I don't think. What, maybe 2 or3 tablespoons? Not going to open a bottle for that. Maybe the height would allow for more filtration media? Like I said, I didn't cut them open so can't confirm that. Do the extra holes make for better flow? I'll use either one with confidence. I would not say the Delco is better than the Mobil 1 though. Unless someone cut them both open and showed me the media and could prove one better than the other. I used to own a couple of Corvettes and Corvette even put a thing on the radiator shroud saying to use Mobil 1 oil and filters. That was the factory install. Not sure if they still do but pretty funny they didn't say to use Delco.

Any products listed in manuals or on stickers on a vehicle are sponsored. It's big business with lots of money involved. Just like products appearing in movies & TV. A company can't use another companies name/logo, or product names/logos, on their products or in their literature without some contracts being signed and money changing hands. Otherwise they'd open themselves up to a trademark infringement lawsuit.

All that you can really take from a specific product being listed in a manual is that it meets the car manufacturers specifications. It doesn't really mean it's better. An engineer just sets the specs for the filter/spark plug/oil/whatever, and the lawyers and managers sort out the details on what manufacturer has a product that meets or exceeds those specs. Product manufacturers pay big bucks to be listed in a manual because it means more sales/money for them in the long term from people who read the manual and think they need to use that product. Just like the OP... :)
