Nice to see AMZ/OIL returned to the US for it's Cummins oil filter.
Any idea who makes them?
Remember the Mexico made trucks were always better quality. So just because it was made in Mexico doesn't mean that it's inferior
I was wondering about that too.
You would more likely put a no-name filter in it Made in USA then a brand-name Made in Mexico?
Sounds odd to me. The Mexis make excellent products.
I still have a case of Donaldson filters. Amsoil filters will probably be made in Mexico again by the time I need more.
Nothing but Amsoil signature series in my truck.
I will be posting results of a friends 13 oil report at 28k on the 15-40 Sig series. Last time he went either 23 or 24k and Blackstone said to go 1 or 2k longer. He forgot so we will see!
Looking forward to that post.
I’m running 5w40 and will probably change oil around 7-8k miles. I hate to think about what the egr is introducing to the engine cylinders and oil.
Same 15-40 in my 15 at 15k samples they always said to go longer once the warranty was up.
Like I said must be a reason then quit using the Mexican supplier.
