Nitrogen gas obeys the ideal gas law, PV = nRT familiar to science/engineering people. Air does this too. The only thing about the nitrogen is it might have less water vapor amongst it. Having less oxygen is also better on the tire lining, not much difference anyway really. Air is just fine.

FWIW, I got this from carbibles.com: Quote from a 24-year man at Ford who worked with oil: "Additives are blended at the proper rate, heat and in the proper proportions by the manufactures of their particular product. Crude supplies are not all the same quality and the additives have to be...

Mummy will need to explain to the kid: "You annoyed and angered the man, so he took all the pies." Maybe the kid will think about throwing tantrums in the future anyway. Who knows if it did any good. Just freeze all those pies at home, they'll keep.

Fram ExtraGuard isn't bad at all. It uses at least some glass fibers to get a similar performance as what the wix does:

Hengst: Same comments as the Mahle. Here's a Hengst, at least it has plenty of surface area even if its probably on cellulose in there with unpublished performance specs:

The Mahle oil filter probably uses just paper cellulose, not sure, and they won't tell anybody their performance specs, but I'd use a Mahle over a Mann, choosing the best of the two bad choices anyway! Mahle:

Fram Ultra is a little harder to compare on just visuals alone, since it uses more of a depth filtration approach to get the best performance of any out there. All synthetic media does this.

Compare the two, the typical cellulose wood-chip-only oil filter for BMW (Mann), and then the Wix one that has more media surface area with glass fibers in there. I like better filtration, so I pick the Wix.

Now lets look at the Wix-napagold-Carquest oil filter which was engineered for BETTER oil filtration:

^^^ Mann (German made oil filter above) is using all-paper filter media, no glass fibers, yet is reasonably average for a filter, will work OK. Notice the pleat spacing, not bad, but you can do better. See my next post below.

Another reason to dislike Purolator. Can anybody there save that company? Jobs are at stake. Good people work there.

Thanks for the warning. Some people have been saying this for years and I think you're right. Why does Purolator oil their elements when this is a known issue? Makes no sense.
