Thanks the detailed write up. I had techstream running this weekend and actually ran a few tests via the tool. Everything seems to be running ok and I think I’m just gonna keep an eye on it and continue to log data along the way. I’m going to...

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...

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...

This Valvoline has NOACK (volatility loss) about twice higher than already high Mobil 1. More oil vaporizes, more of it gets into cylinders via crankcase ventilation. Though initial puff is most likely oil sipping past valve stem seals. Kinematic...

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...

I started using it about 1k miles ago in my 4.7L. Similar situation where I read all the glowing reviews and positive remarks so I decided to give it a try. No price difference from my standard Mobil 1 (synthetic). Nothing to report yet but after...

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...

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...

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...

Yes. Brand new 2019, in winter, many times. Rolling back and forth for 20 minutes on the last stretch of unpaved road, like an idiot. Replaced Toyota oil in transfer case with Ravenol, and it's gone. BorgWarner transfer case is less susceptible...

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...
