Are Car Dealership Oil Filters a RIP-OFF? (Engineer tested)

Great comparison however there is an issue. You apparently purchase your filters from amazon, a place Rife with counterfeit parts especially for brands like Toyota. I would like to see you retest the Toyota filter purchased directly from a dealer. Otherwise I'm quite skeptical of the results.

This makes you think of how great Toyota's engines are to last long with these horrible filtering, I've switched to Purolator Boss 5 years ago after knowing how terrible the filtering was on Toyota's filter. But I still think that shorter drain intervals are much more important than the type of filter.

Awesome video, thank you guys for listening to your subscribers and doing an oem filter video! As a former maintenance technician of a Chevy dealership and a Toyota dealership, I can somewhat explain their reasoning of why they made their filters that way. Most AC Delco filters that I cut open actually do have a bypass valve. The PF53 is one of the very few filters that do not come with a bypass valve because the majority of vehicles they are installed on have a bypass valve internally in the oil filter housing where the filter attaches to the engine. As for the pitiful filtration quality but also the large contaminate capacity of the Toyota filter, it’s because of filter longevity. Toyotas recommended service interval is 10,000 miles whereas GM and Ford and a few other brands recommend 5,000 miles (based on full-synthetic oil). Based on your tests, it’s clear that you can’t always have (in most cases) a filter that will hold a lot of particles and at the same time filter out really small ones such as 20 microns at a 99% efficiency. Purolator Boss and a couple others are the exception but we’re discussing oems. Anyway, that’s my take, keep up the good work!

Thank you for testing the Bosch filter! I've been using them forever. It's great to see that I might have to reconsider due to the build quality issues you've pointed out. I am so happy to see the filter I've commented on being brought to the show. I can't imagine the amount of hours that goes into each one of these tests and then the video production. It is truly appreciated, thank you so much!

Good video. Just so you know in more than a few GM applications the oil filter bypass valve is in the block just above oil filter.

Cool test. Your hard work is appreciated!

This is great, I ALWAYS worried about the resistance/restriction through the filter, something no-one ever talks about. Thank you so much for tackling this issue, specially since I typically use a brand mentioned here. A BIG thank you to you!

Not having a bypass valve in the filter isn't necessarily a bad thing. I'm sure the GM vehicles that ACDelco filter is recommended for have the bypass valve integrated into the oil filter housing. In my opinion, that's the better design because I trust an OEM bypass valve that's part of the engine to not leak and to have the correct pressure setting much more than I trust whatever bypass valve is in the oil filter. Whip City Wrencher has shown that even premium filters can have significant leakage past the bypass valve. Integrating the bypass valve into the engine instead of relying on the filter also eliminates the possibility of starving the engine of oil by using an incorrect, poorly designed, or defective oil filter.

I like all this detailed analysis, thumbs up! But how does small particle filtration, capacity, and flow rate equate to engine life? That's the REAL question! It seems to me like if you change your oil & filter regularly, then dirt holding capacity shouldn't be an issue. So then you get down to the question of what does your engine need more, higher flow rate or finer particle filtration? To answer that question, you have to consider whether the engine is subjected to more short trips, or long trips. To me it would seem like a higher cold flow rate would be more desirable for short trips, while particle filtration ability would be more desirable for highway driving (after the oil is warmed up.) So maybe your test results should be recategorized to help people decide what is the best filter for short and long trips. That would be useful information.

Thanks for doing the dealership ones as requested 😂. Results were amazing.

Great video! I can tell you're getting more comfortable and confident with each video.

Earned a subscriber. Keep it up 💪🏽

thank you for your amazing tests/work. its a game changer and an eye opener

I recently switched to the Motocraft filter after years of using more expensive oil filters after watching some other videos. I’m really glad you did this one. The biggest issue is I heard you could get my filter at Wally World a year ago for $4 and some change. Now it’s $8 and some change. For 4 bucks it’s an incredible value. It’s decent for $8. I recently switched from 5,000 mile oil change intervals to 3000 - 3500 OCI as I have a GDI Turbo and do mostly around town driving. Valvoline High Mileage full synthetic for the win for my go to oil sold at Walmart. Garage Box is $58 for 12 quarts. Ford Boss Me did a video with lab results and the Valvoline High Mileage had excellent numbers. Great video, thank you for your thorough testing!

I love these videos you’re doing great. can you please test the full lineup of Purolator filters I would love to see how they all do.

The Toyota filter results are really interesting. I’d love to see a Toyota engineer explain the choices made there

The Bosch 3330 has been my go to filter for many years with no issues. I can’t find it anymore, so I’ve been using the Fram Ultra Synthetic XG3614. I have a Toyota Tacoma 4.0 V6 Trd sport that I bought brand new in 2007. It still runs great at 149,000 miles. I’m going to keep it forever. 🙂

Not trying to be to nitpicky, but if you tested and AC Delco PF63,PF64,or PF66 are the current high use gm factory filters. You would be testing the newest technology filters.

Perfect! Just what I was waiting for. Thanks guys. More automotive parts tests please.

@Brand Ranks... In a cold flow chart (final rankings) You are missing "15" and have 14 twice. I like your tests. Keep up the good work.
