Same thing with our present 5th generation RAV4. I doubt there will actually be a completely different 6th gen for several years.

Tazio, what grade of oil and brand are you using for your Rav? And do you interchange w different grades or stick to just one. With your extensive readings, do you think there is any detriment to using 0-20 in a temperate climate like So Calif permanently?
Thanks

For my first DIY break in oil change at 1K miles I used a new OEM Toyota filter and quart bottles of TGMO Toyota 0w-16. I have a '21 gas model so for the last two years with the free Toyota Care I have just gone to the dealer (Toyota of Corvallis) and they claim to also use TGMO 0w-16. When I looked through the large windows in the service bay, they pulled down a hose from the ceiling and pumped in the oil presumably from a bulk barrel...so I'm taking their word on this-but who knows? They could have been using anything. In May, my Toyota Care expires and I will start to do my own oil changes again. I have already bought my oil and filter. I will use Mobil 1 Extended Performance 0W-20 with the Dexos and NASCAR certification. NOTE:This is NOT the one that says it is for "high mileage cars" and it is not the "Advanced Fuel Economy" oil. I will use the WIX 51394 oil filter which is slightly longer and slightly bigger in capacity than the Toyota OEM filter. This is the filter used on the 2021 Camry which has our same engine. I think 0W-20 is fine for California. If you have an open road and can drive fast at high revs I think it has better film strength and a higher shear factor and will protect the engine internals. If you are stuck in 100 degree F weather in the endless traffic jams on the 405 in L.A. and the oil heats up I think it will do a slightly better job than 0W-16. I have always stuck to one brand and one viscosity in all my cars. This has varied over the decades of course and with the car. Back in the early 1960s on beater Fiats, English and Italian sports cars and '50s Fords I used non-detergent straight 30W Valvoline. In the 1970-1990s I used Castrol 20W-50 in Volvos and Fords. In the 1980s I hsed Valvoline Racing Oil straight 40W in my autocross water-cooled VWs. In early 2000s I used Castrol 10W-30 in Jeeps. Here is the oil and filter I will install in MAY in my 2021 gas model XLE.

Xlnt info Tazio,
I've been a Mobil 1 synthetic oil user for probably 20 plus years on my Toyotas too. Based on your comments I will go w 0-20 instead of 0-16. I've been checking this oil out Pennzoil Ultra Platinum and am now on the fence of switching oils based on this video and user comments on the video. I also, very many years ago was a Castrol guy.

Regarding the filter, I've used Wix XP for at least 8 plus years and if its micron size filtering matches your filter I will switch to yours. I like the idea of added capacity , Hmmm. will you still be able to get an Oil Filter wrench on it as your filter is longer ? (I use a wrench which goes on the end of the filter w a ratchet wrench)

Pennzoil video

I knew I came to the right guy for advice based on your racing heritage below ..... ; )

Thanks for your response
Much appreciated

Yes -you will have plenty of clearance room under the RAV to use the cap fitting and a socket wrench. Several posters in this forum have been using the WIX 57145 filter for years on 5th generation RAVs and that one is even LONGER than the WIX 51394. Also,I just tested my new 51394 with my Walmart cap wrench attachment and it is a perfect fit on the end of the filter.

Great info, will go w the longer filter !
Great racing career !!!

The WIX XP 51394 version has SYNTHETIC medium and filters down to 21 microns. The standard WIX 51394 I'm using is cellulose medium and also filters down to 21 microns. The stock Toyota filter is also cellulose medium. Here's the deal--the cellulose medium actually does a better job filtering particles as long as you change the oil and filter every 5K miles or so. Synthetic medium is designed to trap and hold particulates for LONGER mileages like 10K. However that synthetic medium eventually allows a greater quantity of particles to pass through and escape.

Here is a video reflecting a number of charcteristics for the Wix XP vs Purolator Boss... check out just after 12 minutes for particles passing thru the filters.... in this test there is a significant difference in what passes thru the Boss vs XP... The Purolator Boss wins in this respect... I have not seen any data to contradict this finding "so far"

How does the vid tests compare to the Beta numbers published by each brand. That's what I would like to know.

Good question, you are welcome to pull the data from the internet of the manufacturers specs and post here if you would. Then, you have to "assume" the mfr tests the same way....

Actually, I find it difficult to believe that the Purolator Boss can retain particles that small and not block the filter which I would think, leads to diminished flow capacity...Perhaps someone can explain that, because it does not make sense to me.
I am using a Filter Mag to retain some metal particles so this may be a non issue in that instance (just thinking out loud)
