Carquest and MicroGuard oil filters

[vwalburn]

Premium Guard Inc (PGI) makes the Carquest Premium. They do not make the Purolator.

Premium Guard and Purolator are all part of Mann+Hummel now-a-days are they not? Would this be why they all look alike?

I know that the CarQuest and MicroGuard oil filters are considered two of the best oil filters on this forum. I understand that both are rated for 99% efficiency at 20 microns. First, is there any difference between the two filters or are they exactly the same other than the name printed on them (i.e are they constructed exactly the same with the exact same internals)? Second, I was wondering if anyone has any data on the flow rate of these two filters? The 99% efficiency sounds great but if they don't flow as good as a less effecient oil filter, you could be starving your engine of oil periodically. In other words, you can make a filter that is 99% effecient at 5 microns, but the flow rate would probably be way too slow for a engine to survive. I'm just wondering if they flow comparable to other less efficient oil filters or does the 20 micron rating cause a slow down in oil flow? Third, are there any other brands of oil filters that offer the same filtration efficiency to the CarQuest and MicroGuard filters?

Carquest Premium is 99.5% @ 20 microns but the Microguard is nowhere close in efficiency. The best basic oil filter is probably the Purolator Red can at 96.5 @ 20 microns; excellent for a basic filter. Purolator and Carquest filters are coming out of the Mann+Hummell empire.

Carquest Premium and Microgard Select are essentially the same filters made by PGI. PGI is not in any way part of M+H.

I think OP was referring to the CQ premium and MG select which, as GW posted, are PGI

When I search " who makes Carquest oil filters " it states Mann+Hummel. Has there been a change?

Nope, Purolator/Mann+Hummel have nothing to do with PGI. They are competitors. Just because one filter brand looks like another doesn't mean they are made by the same company.

MicroGard Select is advertised as 99% @ 25u - could be same as the Carquest Premium but O'Reilly chose to use the 25u spec to be conservative. The guts and media look the same between the two. So it's close to the Carquest Premium. Probably equates close to the 95.5% @ 20u if 99% @ 25u.

Old info, A.I. can't keep up with oil filters.

Those are all made under PGI. Carquest is in the upper LH corner.

CarQuest changed to PGI like 3+ years ago from M+H (Purolator)
