Yes, I plan to start at 3000k. Did a drain and fill at 500 (TGMO 0w-20) & 1500 (Mobil 1 Extended Performance 0w-20).
5000k minimum. I plan to adjust this based on UOA results.
Yeah, turbo non-hybrid.
It's not too hard. Valvoline Restore and Protect 5W-30, Mobil 1 ESP 5W-30, or Mobil 1 Euro Car 0W-40. Pick one. Be happy.
Not terrible. Mostly marketing. (Worked, it seems.)
Already at 3,000,000 miles? Impressive. What are you hoping to see this early in break-in that will give you good, actionable information? Let me guess, Blackstone too?

I'm running ultra platinum 5w30 in mine currently and no issues..I may swap to esp 0w30 when I run out of ultra platinum or I may not. Euro platinum is also good choice as well. Any of those three are fine and depends on price and availability for me at this. At 5k intervals, you're really trying to split hairs
I'm not sure about this. Pennzoil Ultra Platinum is a great oil I think, especially in the 5W-30. However we see enough issues posted here even with strict 5k changes I think it does matter. Especially in these new turbos that are wringing every last bit of power out of a 4 cylinder engine. They are hard on oil. With a brand new car, probably a loan, increased insurance, etc etc. it's not even a rounding error to go up to Valvoline Restore and Protect 5W-30 or Mobil 1 ESP 0W-30 on the total cost of ownership and ensure you won't have oil-related issues. You won't know you have a problem until 75-100k+. You don't want to be one of the ones who finds out the hard way that the new Toyota 4 cylinder turbos burn oil if you don't run a good one.

I mean splitting hairs between those oils mentioned at 5k intervals.
Ah gotcha. Yes in that instance I agree.
Hello,
I purchased a 2026 4 Runner Limited Hybrid about a month ago. I intend to drop the factory fill and send off for analysis within the next week as some mileage has accumulated. The next fill will be with 5W-20 Pennzoil Ultra Platinum with the OEM filter. I will run this oil for about 3,000 miles and retest.
I know there's a lot of debate over the 5W-20 VS 5W-30 in Toyota engines, so I want to see what the test results show. I live in AZ so there's plenty of heat to go around and with this being turbocharged and having start/stop I believe it'll be a good test. This vehicle sees both city and highway use.
If the original poster is fine with it, I'll post my results onto this thread and we can compare results.
Thanks!!!

The site is definitely not a BEST oil selection site. These types of posts were basically banned for years.
I can recommend Amsoil OE 0W-20 but is it the best? No. As good as ANYTHING mentioned in this thread? Yes. Better than any oil out there? No idea, nor do any responders here know.
I hope my post helps you think.
Generally speaking most good synthetics should be ok with your turbocharger heat and ring deposits but there are some like the Amsoil Signature Series that run very clean in the ASTM Tests
What on earth are you hoping to see and learn from sending the factory fill for a UOA?
How do you think that a UOA with 5W-20 is going to help you decide on a 20 or 30 grade oil?
Make sure you send to Blackstone so the results are 100% questionable and to fully make this a useless endeavor.

When I sampled the factory fill on my Corvette I was mostly concerned about the fuel dilution, given the fact that it is DI and I knew that the car would have been subjected to a lot of cold starts and short running time during the process of getting it through the assembly line (including the short dyno test to check the ABS and the water test for window leaks) Then it’s moved into the back parking area of the factory, then onto a truck then onto a train and then onto another truck and then finally arriving at the dealership. It did end up having 2% fuel in only 1100 miles. I also wanted a base line for all of the major wear metals, so that I could see them coming down on future intervals. But like most of us here I think it’s just curiosity driven

I would run any of the following year round 0W30, 5W30, 5W40, 0W40.
If it is mostly a grocery getter and daily driver I would lean towards 0W30 or 5W30. If you regularly hit the trails and sometimes tow I would lean towards the 5W40 or 0W40.
If it where mine I would toss Mobil 1 0W40 in it and run it year round!

I can definitely understand the curiosity. I mostly see UOAs as useful for information on extending intervals, so unless it's just for kicks, I'm not sure what actionable information you're going to get from the factory fill.
Do you think that an early UOA will be reflective of fuel dilution after break-in? You're going to be doing some early, more frequent dumps (or most here will), so I'm not sure if it will be reflective of what your normal 5k OCI will show later on after (or later on in) break-in.

In my case this was also my first DI engine and knowing that fuel % right off the bat was important to me. I also wanted to validate my decision for dumping the FF at 1100 miles. I’ve always done early oil changes on every new car I’ve owned but this was the very first UOA I had ever done on the factory fill.
It was nice to see that on the second UOA the wear metals were much less than on the first one and fuel was now down to 1%. Then on the third UOA the fuel was zero and wear metals down yet again. I wish I had continued doing UOAs after that because I would have established a good trend if I had been doing them for every single oil change from day one.
Here's the results from the first oil sample at 1,370 miles. Please chime in with any comments that may be helpful. When I changed the oil, I put in Pennzoil Ultra Platinum 5W-20.
The vehicle was driven in a mix of conditions, and the 4 Runner is a Hybrid with the start and stop feature.
Thank You

Out of grade in only 1400 miles. I would reiterate my advice above:
I would skip Speediagnostix. Too many errors and too expensive. I don't think you need UOAs frankly if you're not running a boutique and trying to extend intervals. Use Polaris, Wearcheck, or Oil Analyzers.
Run one of the above and change every 5000 miles and sleep easy. Or you can run a lower quality oil, waste money on UOAs, and keep coming back here for advice that you won't follow. I guess it's up to you.
I would use 5w-30 minimum! Oil geek just did a video on his Tacoma, same engine, he changed the oil at 500 miles, 1500 miles and again at 5000 miles. When he did oil analysis the 0w-20 had already sheared out of grade at just 3500 miles.
