2025 Toyota RAV4 XLE non hybrid factory fill oil samples

[Elmo Howe]

Good evening BITOGers. Wanted to share the results of oil samples taken from my 2025 Toyota RAV4 XLE non hybrid. First sample taken at 31 total miles on engine/ vehicle and second sample taken at 583 miles. I called the lab to clarify that I thought that the factory fill " should be" 0W-16 GTMO if Toyota does their factory fill with what is recommended for the vehicle owner's usage in the owner's manual. There had been some initial comments from the lab on the first sample about " additive levels different than.....identified lubricant. "
I expected a high silicon level due to a new engine / vehicle. I purchased the vehicle in the same month that it was assembled and it had a total of 7 miles on it when I drove it off the dealership lot. I had similar high silicon levels in my previous Toyota RAV4 LE that I was able to get corrected through doing 4000-5000 mile OCIs by using VRP and CarQuest Premium oil filters.
I did an oil filter change on the vehicle at 71 miles and topped off the oil level with 2-3 ounces of TGMO 0W-16 full synthetic oil.
I know that the comments regarding the induction system are meant to help with identifying the high level of silicon, but this brand new vehicle has no problems with the " induction system ". I have verified that everything is as it should be.
Just wanted to share what a Toyota factory fill looks like when lab tested.

I'm not sure how to attach files to a post, since I'm not too good with computers and electronic devices, so thus the picture of the UOA.

That’s a lot of Moly, I run the same in my Camry. Looks to be breaking in well.

The only other non TGMO oil that comes close to having as a of a dose of moly that I have used are the HPL PPPCMO 5W-30 and the HPL no VII 5W-30. I ran them in the 2023 RAV4 LE that I traded in for this 2025 RAV4 XLE.

Yeah, the si should come down after a while, just keep at it.

Iron is very high for the mileage. Once the engine breaks in, iron should be a little over 1 ppm per 1k miles. I have the same engine. You can see my numbers

TGMO needs all that Moly because their base oil is not great. Mobil and Pennzoil get the job done with 80 ppm Moly. I think their Moly is also a much more potent flavor. Don't let those big Moly numbers impress you, there is a reason why they use so much to meet the spec. I watched a video by Oil Geek where he explains the difference between Pennzoil and QS. QS loads up the oil to meet the same performance spec that Pennzoil achieves with less because of its superior base oil.

OP's engine is still "new" so it will have higher metals than yours with 200k.

My understanding is that Mobile makes the various oil blends under contract for Toyota to Toyota's specifications. And, agree that high Moly is " relative " to the type of Moly used in the blend and what is spec'ed by the " brand owner ".

Meaningless UOA. Still breaking in. Check back in 20k.

This is further evidence to me that the factory fill is not the first fill. Thank you for posting and spending the money on a new engine UOA.

I have previous experience with this same engine in the 2023 RAV4 LE non-hybrid that I used as a trade in on this 2025 RAV4 XLE. So exact same engine. I purchased the 2023 from a rental car company and it already had 12563 miles on it at the time of purchase. It still had high levels of wear metals at that time and for an additional 10-15k miles. What helped me best in getting the wear metals to start trending down was switching to a higher viscosity oil - 5W-30 VRP from the Toyota, then Amsoil, 0W-16. By the second or third 4k-5k miles OCI, the wear metals and the really high silicon levels had come down to a more " normal" level for the engine type / manufacturer.
So that is the approach that I am taking with the new 2025 Toyota RAV4 XLE.
I currently have a little over 1600 miles on the vehicle and around 900 miles since the last oil change ( which got rid of the factory fill oil ). So I will be taking more oil samples along the way to see what happens with the wear metals and silicone levels for this engine and the oil. I will post those reports as I can. For the benefit of the community and for others that have this same engine type.
The vehicle currently gets an equal combination of city and highway use in San Antonio Texas and the mild to very warm spring temperatures that we are now having here. Our consistent 100 F degree plus high dew point brutal summers are the biggest reason for my decision to boost the viscosity level up to a XX-30 weight oil. I'm one that wants the added " cushion" of a higher Hths that the XX-30 weight provides for to help with fuel dilution, mainly, and the excessive idling time of rush hour traffic in the summer heat.
So, stay tuned, as the TV people say.
Hope that this current and future UOA information is of help to the community.

My intent with the UOA was to establish a baseline data point for various wear metals and overall oil chemistry of a Toyota factory fill. So that myself and others with this engine brand and type would be better able to see what happens in the early stages of this engine types life.
I realize that it is a continuing slow process to get to the " sweet spot " of an engine break in. So I will be checking even earlier than just 20k miles.
Thanks for your response.
