Toyota did the service on my wifes 05 Rav 4 using Genuine toyota motor oil and Denso filters at sub 5k oCI. TOYOTA KILLED IT.

You are obviously getting self conscious in this conversation to start an unprompted pis sing contest over credentials.

This statement makes no sense and is irrelevant. I'm not Toyota poster child. I am a Honda loyalist first, and just purchased my first Subaru. But I have worked on many Toyotas in my time and they are tanks and I don't want someone spreading isolated information about a legit company.

I had an '89 Toyota truck with the 3.0L V6 ... always used Toyota filters and regular conventional oil (Quaker State, Castrol, etc). It had 145K when I traded it in for a new 2005 Tacoma. The 89 ran like it was new ... always passed emissions tests and didn't burn any more oil than it did when it had 40K miles on it.

I'm using OEM Toyota filters on the '05 Tacoma with Mobil 1 5w30. Runs like the day I bought it new ... guts of the engine are clean - like new looking.

These are good depth media filters and same as OE on the car - the toyota dealer service filters are not OE equivalent. I have purchsed JAPOn Denso from McGeorge too - I think pn90915-1004/3 but I had dealer do OCIs and they put on the Thailand denso and used Genuine Toyota Oil(?). Rav4 Engine was DEAD at 57K miles, clattering and burning oil. Something wrong here! My yaris engine will not run on the Thai denso filters either. But many think I have a TC tensioner problem. HAD tc tensioner problems on ALL my cars! Next car - no chain! I wish I had the LAB equipment to study the Thai denso filter to PROVE what is the issue with it.


I have a box of ten of the Thai Denso filters also, trying to use them up. I have one on the Prius now and it hasn't changed anything that is noticeable. Every filter acts the same on this engine so far, which is to say no action to observe. The Yaris and Prius have essentially the same engine block. There is plenty of room for the longer 90915-10004 Japan Denso. I think the Yaris, at least one year, had the best repair record in Consumers of any car.

I also use the Toyota Densos on my lawn mower engine, and it does fine. No the Prius is not a lawn mower as I have heard suggested. It seems an unsolved mystery, the filter/oil problems described.

Actually I have never had a filter problem since I started changing my own oil in days of yore, or noticed much real world difference between one or another filter.

The 05 Rav4 has a 5/60 powertrain warranty so they should fix it, especially being dealer serviced, with no issue.

I agree, Bill. They seems to both flow and filter quite well (in the used oil analysis I've seen as well as bench testing at home), and the ADBV actually work, in my experience.
Excellent filters I think.

Lowell Technological Institute - primarily a Plastics and Polymer Engineering school, formerly Lowell Textile. We "had" a working nuclear reactor on campus - but was shut down when I attended MANY years ago. The campus is now part of University of Massachusetts. I wasnt too happy with my education there - a real degree mill. Obviously, they didnt teach me about the finer points of Toyota engines

They would not repair it stating that 1qt oil usage per 1000 miles was "normal" and the engines are characteristically "Noisy". Water pump started leaking in the winter, so traded it in on the Subaru. Our cars are NOT garaged and have many unaided start at -15F deg in the winter. Thinking about getting a block/pan heater for the Subie.

Since there exist no relevant data, we rely on and relay our own personal experiences. It has been insinuated on this forum that my experience is not credible and I have been personally attacked here. There exist enough co-incidence in my experience servicing the 1nz and 2az to indicate that there are indeed issues with the filters I PURCHASED in my GEOGRAPHIC AREA. I do not have the resources to investigate further. You may choose NOT to believe me. You may truly have not experienced problems servicing YOUR toyotas. But you should NOT discount my personal experience. What is this forum for? The current Yaris runs acceptable with Castrol Syntec and a wix filter, not so with service replacement parts (Japon Denso work OK.) I would prefer even moreso to use the Purolator(bosch) in small form factor cartridges (due to wix base-mounted component bypass) but the threaded nipple on the filter mount is short and will only engage 2 threads on the purolator. I loved the rav 4 and lost a great engine way too soon. Just a word of caution - that is all.

That's a shame. Do you know what went wrong with the filter?
I've never run OEM oil in the 2TR engine, but it sure likes the Denso filters just fine.
 
No, but after an OC the TC tensioner on the rav stuck and had a shower of tappet noise that didn't go away. First suspected the oil, then thought NO WAY. Changed out the filter and all was well. I Fill my filters before installing. Not sure if this helps or not - now you have a slug of oil in between the air in the pump to filter galley and the mains galley. Possibly causes hydraulic hammer on the TCT piston. Filters LOOK mechanically fine, but I have no test fixturing or methods. I may try this one more time with the service replacement (Thai)denso(toy pn 90915-yzzf2): remove and replace the same filter (denso) after the OC, and see if the noise goes away - in the odd case there is a 'loss of prime' issue. Had this issue with 3 engines that use the SAME filter, e.g: 2.3l Suzuki Aerio SX, 08Yaris 1NZFE and 05Rav4 2AZFE. The only common factor was the filter. Suzuki had a TSB on the filter and switched OEM to an Austrian plant(!)

Are not they big bucks or same as K&N? Not a fan of champ. Guess a few dollars one way or the other does not matter over a 5000 mile OCI if you are comfortable with what you're using ...
 
They are $8 online at a Toyo dealership that sells Scion parts. No biggie for piece of mind. Plus, if there is a warranty issue, its still a Toyo part.
 
The 96 infinity G20 2.0L motor uses same filter if you want to try something different - dont know who the OEM is for Nissan service parts. May stop by dealer to see what they got. Expecting big $$ here too. I Would like to get a Japan sourced filter.
 
I've used 11 of the Thai-sourced Denso/Toyota OEM filters (both the 90915-YZZF1 & F2 types) on my Vibe and they've readily met my expectations. Since I only have one Blackstone report on the engine and I've only cut open about half of those filters for inspection, perhaps that's a bit of an anecdotal observation. However, in my experience...and that's all that matters to me

...these are well-built filters.

That said, my case of OEM's is about depleted, so next up will be a small stash of blue-can Pure One's. And then, after that, I'm off to Bosch Premiums, which when purchased on sale at Schucks/O'Reilly's, is one of the greatest values to be found (shipped), I'd continue with that regiment.
 
like the way DENSO applies plastic over open end of the filter to keep elements out and pre-lubed seal too . Nice touch .

I like denso filters. Lots of media. Thermally bonded. Some are made it Japan, and some in the US as well as thailand. I buy mine from sparkplugs.com in bulk and they sell them relatively cheap. Toyota dealers overwhelmingly use denso filters. I also buy the cabin and engine air filters in bulk from the same place. Take a look at the denso engine air filter vs factory, and they are basically identical and very nice filters. Sorry ARCO had a bad O F experience. Every company will have a product that is substandard. Quality control is not 100% perfect for anybody. I personally saw some visible defect on 3 out of 6 Bosch oil filters and 1 out of 2 Mobil 1 filters I took out of the box at Auto Zone. That got me to buy the Densos from sparkplugs.com

My local Toyota dealer uses Chevron bulk oil.

I feed our 3MZ-FE(the 1MZ's improved brother, but still prone to sludge) M1, SynPower or PP and Toyota or Wix filters exclusively. Ditto on the Prius and a 1991 Lexus.
