I haven't seen any teardowns show issues like that, but it hasn't been out for all that long. I did watch an interview about the the formulation of the oil and one of the biggest challenges was making sure it would both suspend the debris well so it would depsit in the oil filter and make sure...

It's a psychological problem. I don't really have any good reason not to keep using it. I still have some unfounded fear that it isn't as good of a lubricating oil. It seems too good to be true that an oil can clean the engine, not have any additional wear, and costs roughly the same as normal...

UPDATE: Just a quick update on my '16 with 5.7 and 115k miles. It's been a few months now. Have not made it to the next oil change yet. Only around 2,500 miles since using for the first time. But - I can say with a pretty high level of confidence now that the chain noise on startup has...

Throwing this out there - PCV valve stuck open could be a cause. Assuming the fuel trim is off due to the engine having more air to one bank than the ECU thinks it has. A PCV valve that is free-flowing addtional air to one bank would genreally cause the ECU to fix the lean O2 reading by trimming...

I'm sticking with 0W20 for my climate (south central Alaska). I have a lot more -20F days than 100*F days. Actually zero 100*F days. The hotest temperature it has reached since I moved here is about 73 degrees. So, I think I'm probalby better with the 0w20. But I might go to a higher viscosity...

Juste an update - it only happened once. Hasn't happened again. I've been starting it every day with the remote as I walk up after work to see if I get any smoke or smell and also listen for timing chain rattle. The news so far is all good. Have not had another instance of smoke. And the timing...

I'll pull apart the filter on my next change and put some pics on here. The 5.7 cartridge style filter is really easy to just break the ends off of the pleats and pull open to see what's in them. I didn't keep my last one, but there's usually just a small amount of visible darkenign around the...

Thought it might be worth opening a thread about this oil. My Tundra is now at about 115k miles and there's a lot of pretty good looking data coming out regarding this oil and it's ability to help break down some of the oil deposits in older engines. I have noticed over the winter that I can...

That's intersting. I've never had the dash lightup, but otherwise I'm not really sure if I'd ever know if either the ADD disconnected but the transfer case didn't or the reverse of that. I'm assuming I'd get a dash light error, but I'm not sure if that's the case or not. I changed the transfer...

I took it out of 4wd for the first time since probably November of 2025. I typically put it in 4hi sometime in the fall and just leave it there for the winter. I'm in Anchorage AK and the roads never really melt off during winter so I just run it in 4hi until spring. I'd guess about 2-3k miles...

I'm super curious to see how you like the rear helical diff with ATRAC. It seems like a perfect match, but I haven't seen anyone with that combination do any sort of review.

Got out to find some blue ice. This is a lake at the base of a glacier and in winter the lake freezes all the icebergs in place and you can get out and see them up close. Can't go safely to the face of the actual glacier though - it's moving and the ice is unpredictable. I'd usually run out in...

I think I maybe could have quieted it down by disassembly and carefully rounding the corners on the spider gear teath and maybe also polishing a bit. It's just a lot of work and down time to tear it apart. For all I know the e-locker front might be just as noisy too. Even the base SR5 4Runner...

It was quite a lot different from a typical spider gear set. The gears are still lubricated with some oil film in this video I made of it. Imagine this at 600 rpms and that noise was significant. Not a dealbreaker for a trail rig. But was a dealbreaker for a daily driver. I'd say it was maybe...

I think for the LM2 to work as a conversion motor it would need a stand alone ECU so you could adapt it to something. Thinking a little bigger - the full size Duramax have stand alone options available for software. But I think they're realistically too heavy and too powerful for the Tundra...
