First Oil Change at 5k instead of 10k (1 Viewer)

The Tundra and the Lexus GX 550 use the same engine.
The Tundra powertrain also uses HV, but the engine is the same.

The V35A engine is produced in both Japan and the United States, depending on application and build year.
Primary manufacturing plants:
1. Toyota Motor Manufacturing Alabama (TMMAL) in Huntsville, Alabama, builds the V35A‑FTS for North American trucks and SUVs such as the Tundra and Sequoia.

2. Toyota’s Tahara Plant in Aichi, Japan, also manufactures V35A engines used in both Lexus/Toyota applications.
In practice, most North American truck applications (Tundra/Sequoia) use Huntsville‑built engines, while some Lexus and global Land Cruiser/LX/GX applications use engines assembled in Japan.

In the market, V35A engines at both plants have experienced failure.
Do your research, you will find that beginning Model Year 2026, there was a manufacturing change point for the V35A engine block design to strengthen the cylinder walls and main bearings design and materials.

Supply to assembly plants depends on demand, "JIT" (Just-In-Time) manufacturing.
This means Japan built V35 engines could be sent to the U.S. TMMTX plant for Tundra/Sequoia, and/or the V35 engines manufactured in Alabama could be sent to Japan for related Lexus/Toyota production for Japan domestic or Asia distribution, as well as the Lexus GX 550 to the U.S. market.

Good luck.
 
I paid my dealer to do oil changes at 1000 miles and at 5000 miles and will do them every 5000 miles from this point forward. The dealer will do my next oil change at 10,000 miles at no additional charge per the maintenance agreement.

I just choose to take this more conservative approach to oil change intervals as a relatively inexpensive insurance policy against premature engine wear.
I plan to do the same oil change interval as you.
 
The above video's sound a bit like AI slop. Not sure if any of that information is actually real or not.

I just changed my wife's Luxury plus at 1000 miles. Firs time really looking under the hood and undercarriage. I have a two post lift so the oil change was a breeze. Only issue I had was aligning the skid plate. Three different sized bolts/connectors for that one piece!
 
My 2 cents...
If your vehicle is leased, follow the owner's manual; if you purchased it, consider more frequent engine maintenance.

You can follow the owner's manual and listen to the dealer...Or change the engine oil and filter more often.
The V35A engine should have regular maintenance every 3,500-5,000 miles, which is not excessive.
Following the 10,000-mile engine oil change and not checking the oil level regularly is asking for trouble.

Check the engine oil level regularly and change the oil and filter more often.
A break-in engine oil filter change should be done at about 1,000 miles. Thereafter, every 3,500 miles.

The GX 550 V35A engine has known wear-and-tear issues with the engine's main bearings.
The twin turbochargers generate significant heat in the engine oil, contributing to its breakdown.
You decide what's best for you.
Good luck.

More misinformation.
I use SPEEDiagnostix, SPEEDiagnostix - Express Oil Analysis.
Watch the YouTube channel,
V35A engine issues,
Good luck.

Lots of misinformation bud. Get lost.

They are. Posted here to get Youtube view count.

If you don't mind me asking - where did you find info about a production change for 2026 model year V35s with stronger main bearings & revised cylinder liners? I haven't heard of that yet.

I don't doubt the information - Toyota is famous for Kaizen & continuous improvement - but I simply haven't even heard it anywhere.

It’s not based on anything verifiable. With as much of a spotlight as there has been on this engine some YouTuber would have recognized this engine change and posted a video about it with actual info instead of a weird AI voiceover with no proof of anything.

The main bearing was upgraded back in 2024 around April/may which coincides with the cutoff date on the recall. The part number on that main bearing change was noticed by car care nut a year prior to any recognition of it by Toyota/lexus, so I’m a bit skeptical of videos like the one above.

Yeah I recall seeing that video by car care nut too. If memory serves me right, he said the part number changed. Which indicates a new and improved main bearing.

There’s only one [unofficial] Toyota source I trust and that’s Ryan Gregg. He’s been tracking the V35 failures from the beginning. He’s connected and networked himself with folks, at both the corporate and dealer levels. The dude has gone as far as track part number changes in the V35.

You just sent me down a rabbit hole.
 
You just sent me down a rabbit hole.
He participated in an interview a few months ago:

If you really want to go down the rabbit hole, then watch the entire 2 hour interview. 🤓

IIRC, he may be the guy that started and maintains the Google spreadsheet of Tundra and Sequoia failures. I also know he’s in a lot of Toyota FB groups watching for any failure posts on the LX and GX.

Ye I spent about an hour reading his comments on Reddit. Haven’t heard him say much on the GX, but I’ll listen to the video.
