I've been using Mobil 1 oil and OEM filter for years.

I am not sure if any of these videos have been posted, but a youtuber compared all major brands of motor oil, and found Amsoil and Pennzoil to be better than Mobil 1. I have been using Mobil 1 for decades, but will probably be switching.
Here is the link to the last video in his series.

There are several videos before the one I have posted, comparing various brands of oil, Mobil 1, Amazon Basic, Lucas, etc. They are worth a watch.

So you switching to 5w-30 too?

This was cool. Thanks for posting.
My favorite part was how Amazon Brand Oil performed better overall than Mobil 1.
The Mobil 1 fanboi's are going to freak
I can already hear the excuses now.

Above info is all correct. Exxon / Mobil does make Toyota oil HOWEVER it is completely different than their off the shelf 0-20 It's a specific formulation made exclusively for Toyota. IMO, there is a reason for that. I am 2K miles away from my normal 5K mile oil change. I have used Toyota oil, Mobil 1 oil, Valvoline oil. The engine ran quietest with the Toyota oil so that's what I plan to use for the rest of the time I own this truck, which will be quite a while. Same goes for my 2019 Highlander, It'll get Toyota oil and OEM filters.

For all future visitors to this old thread, visit the Petroleum Quality Institute of America website PASSENGER CAR MOTOR OIL | The Petroleum Quality Institute of America and in the graph shown, sort the Grade column from highest viscosity to lowest.
Scroll to the 0W-20 section and select the oils you want to compare.
Mobile 1 variants have formulations with molybdenum between 79 and 88 ppm.
The Toyota OEM formulation made by Exxon/Mobile has 787 ppm of molybdenum.
There are many other differences in the formulations, but the comments made on the Bob is the Oil Guy forum point to the difference in molybdenum concentrations as significant.

The PQIA website is a good source for reference.
But realize that there’s a lot of change going on in motor oil development. There was a recent transition to API SN PLUS, on the way to API SP. They haven’t caught up with testing and reporting results of all the brands yet. The Toyota oils on their list are still API SN, but what you buy at the dealer now is API SN PLUS. And next year there will be API SP. The chemistry numbers will be different for SN PLUS when they eventually get around to test Toyota oil. So, stay tuned, hold tight, and don’t worry.

Indeed. Thanks for that comment
@ ElectroBoy
The API SN PLUS classification licensing started May 1, 2018 and the BITOG test on their website (as of today) shows they purchased the Toyota OEM (API SN) oil on 1/24/2018, so the test is now 2 formulations old (API SN -> API SN PLUS -> API SP/ILSAC GF-6A).

It seems the API S# designation doesn’t necessarily mean the oil formulation changed, it means that the oil meets the relevant API testing requirements. The Toyota SN oil could be the same formulation as the SN Plus oil.
It will be interesting to see if any SN PLUS test results are posted before they test the SP version.

Some folks need to quit obsessing over Moly content.......some oils go another route on wear additives and a lower Moly count is not a sign of a less effective oil. Most of Projectfarm's ''tests'' are irrelevant to practical use tests.

@ 83Mule
- Not obsessing, just pointing out how to find actual data for differences between oils when a question like the OP asked is asked. Toyota merely recommends TGMO or equivalent ILSAC GF-5 0W-20 (except for Puerto Rico).
@ ElectroBoy
- Correct, and also vice versa. A post on the BITOG forum from Aug 2020:
"There is a four-digit formulation number (revision number) on the back label of all ExxonMobil oils. By looking at this number, you can tell what the formulation is.
The original TGMO 0W-20 SN had RN5953. It was Group-III-based and looked liked it had a lot of polyol ester (POE) if my FTIR oxidation number was correct. It also used trinuclear moly.
Years later PQIA tested a TGMO 0W-20 SN that had RN6378. It was GTL-based with a very high amount of 787 ppm sulfurless Molyvan 855 moly. It also likely had some POE according to Russian FTIR data, but it was only a few percent if at all. TGMO seems to like to have ester.
The SN PLUS version you posted also has RN6378; therefore, the formulation hasn't changed for the last two years or so. You can see the PQIA VOA of this formulation here. Note that the PQIA version is labeled SN but it is the same RN6378 formulation.
Now, someone needs to find the SP bottle so that we can see if the SP formulation is different."

I've tried most of the mainstream oils over the last 208,000 miles and came back around to toyota OEM which the local dealer sells to me for the same price as M1 at wall mart.
I have noticed the engine stays quieter longer with Toyota oil. Every time i pull into my garage I always listen to my engine for a few seconds before shutting down. Been doing this for 8 years now and I can usually hear when something sounds different like when the ticking gets louder. I also change it every 5-6k despite the 10k recommendation. Run OEM filters and still have the plastic housing and a cheap pennzoil filter wrench with no issues so far.

In that post on BITOG:
Toyota Genuine Motor Oil - old -vs new (latest) | Bob Is The Oil Guy
Later in the thread someone pulls up a bottle of API SN 0W-16 and it also has an RN6378, same as the 0W-20. Hmmmm... Kind of makes me doubt that the RN number indicates a formulation identifier. The author’s explanation wasn’t entirely convincing.
But in any case, PQIA reports that analyzing some reports of oil manufacturers formulation of the SN PLUS oils showed they typically reduced calcium and increased magnesium. If you look at the numbers they describe, they approach the Toyota numbers for these two elements. Maybe the Toyota SN formulation already hit the sweet spot to meet SN PLUS.

I have used the OEM Toyota oil & filters on my 2010 & now on my 19' and see no reason to change. But I change my oil @ the 10,000 mile intervals (did the 1st @ 4000 miles) because if the Yota Engineers say 10,000 then they must be pretty darn confident in the oil & filter lifespan.
