How important is an OEM oil filter?

One thing to be concerned about is flow rate. I'd hate to use a filter that had a slower flow rate than factory. Good filtering is great but if it restricts oil flow pressure. Not knowing this I generally prefer to use OEM.

How do you know it would hurt the oil volume flow rate to the engine when the oiling system uses a positive displacement oil pump? Lots of data shows aftermarket oil filters flow and filter really well, probably better than most OEM filters.

If you order several of them or order other genuine parts as well, it would be pretty cheap. You can also look at what other dealers are charging at this official Toyota Parts website.

I've been using the least expensive aftermarket filters of various brands for the past 46 years and have ran a few cars to over 200K miles and one to over 500K without any issues. As for oil I've used everything from major branded oil to store branded oil mostly of the conventional variety. The only engine I've ever had that wasn't still running when I quit using the car was because of a dropped valve seat and had nothing to do with oil/filter.

No the dropped valve is absolutely related. A non oem filter created enough negative hydraulic pressure because of the incorrect silicon bypass valve pressure, this in turn deactivated the Knudson valve which caused a spun muffler bearing, the spun bearing created a 10000 psi back pressure which forced the valve seat out of the pocket. If you would have used an OEM filter that wouldn't have happened. And you call yourself a car guy, shame on you sir!

They most all have had free shipping with $75 online, and have 10-15% off sales at times. Toyota air filters are well priced too. I was buying everything from one place, even spark plugs.

The dropped valve seat came from Ford cheaping out and using inferior materials for valve seats in the 1.9 and 2.0L SOHC engines used in the Escort from the '90's until they they stopped production of the Escort in the early '00's. In my case the engine was still in good shape at about 220K miles. I'm not sure but I think some of the early Focus were also included.

Now I see the Oreilly “OEM” is made by Premium Guard. So it’s not really OEM?

I'm using Parts+ filters that were made by Premium Guard on my '16 Nissan. When I bought the car in '19 I ordered a dozen filters for it from Rock Auto at a final cost including shipping of about $2. each.

Wow dude it's a JOKE!!! Knudson valve? Muffler bearing?
 
It’s a mass produced Toyota four cylinder power plant, you’re going to be hard pressed to find something that won’t work well. You could pick a different filter at random every time and still not have issues.

That said the OEM filter from a dealer is the “best” for this vehicle I’m my opinion cause it’s inexpensive and it’s one less thing to have to worry about.
