Best oil Filter

Have used this filter on 3 daily drivers over the last 10+ yrs. Work great/

Filter works great can tell oil states cleaner longer. Even though I have a diesel it removes a good amount of soot from oil

This filter really does the job cleaning the oil. You can actually see the difference in the oil. Much cleaner during oil changes.

Cost effective and works as advertised. Confirmed by oil analysis.

Cheap insurance.

You still haven't spoken to your buddy bob about his pathetic packing. Are you afraid to speak to him ?? Any further questions about "How'd we do ?" I will just rate one less star each time.

The filters are heavy all theses filters are heavy. Amsoil has best price. and best oils. I used on my Dixie Chopper industrial 3360 HP. I know I have a great filter for my oils.

When I started using Amsoil products, I added dual filtration. Currently I have 241K on my 2002 Superduty Truck and I hope it continues its service to us for many more years to come. It keeps the oil cleaner longer and I am not worried about longer service intervals between changes after a number of oil analysis's have shown the oil is in good shape.

Almost all of my stuff is older (Pre-2000) both Gas & Diesel, most of it with unknown maintenance history and I love these things! With some quality oil & sticking with monitoring levels & visual condition you can really cleanup the inside of things and once cleaned out they really extend oil changes. The only downside I can find is once you've got things cleaned out sometimes it's hard to see the oil on the dipstick!

Very much pleased

with the egr on these the oil is even dirtier than previous diesel engines w/o egr. not expecting the oil to look exactly like out of the bottle new, but I know this filter is catching the extra contaminants from the egr system.

What can possibly be better than Amsoil? This filter is so good it is second to none!

Packed in a manner so the product protects the paper. Shouldn't the paper protect the product ?? 🤔 Have pictures if you'd like to see. Tell your buddy Bob he needs to sharpen his pencil.

Installed on my duel 4-53’s on out Hatt LRC. Teeing into the oil pressure transducer as directed by documentation, caused too much pressure drop at the transducer. Both idle and WOT pressure reading off by at least 50%. There is a port on the front of the oil pump on front of engine I used as a supply to the bypass filter instead.

merci

I like this product & most generally have had great purport from customer service, except for with this product. They told me to run this filter for about 80k miles! This filter only last realisticly about 18,000 miles MAXIMUM!! I change mine about 16k so I'm protected.

Run this filter with bypass system and my oil has a noticeable difference in soot contamination and now can run oil intervals twice as long no problem.

The 2 micron bypass filter permits much longer oil change intervals without harm to the engine. On our diesel, we typically do 30K oil changes. But the truck is only used for highway towing. Lab reports always come out perfect. It's quite a savings as oil certainly isn't cheap.

I'm afraid AMSOILS multilevel marketing system (Ponzi Scheme) has finally run it's course. I have been using their products for many years but their dramatic price increases is going to make me an ex-customer. This is a great filter but as far as I know AMSOIL is the only one that makes it. If I can't find another source for this filter I will remove my whole AMSOIL bypass filter kit and find another kit. I've already switched to Royal Purple diesel oil. I'm sure no one will see this review.
