He is talking about extreme cold here though. 0-20W oil is rated up until -40F, that is a once or twice a century even event even in here in Wisconsin. Yet he says you can skip warming the oil and drive gently, which is common sense.

Transmission heats up from friction and through the heat generated by the engine transmitting through the torque converter. Some heat may also be transferred by the trans cooler capturing heat from the radiator. It will take forever to heat the transmission by idling the engine since it takes so...

On a modern engine, idling to heat it up causes more wear than driving it off after 10-15 seconds because engine idles at a low operating temperature for an extended period of time, rather than heating up much quickly during the drive. Time it takes to back out of your driveway is more than...

Can you get injected but not burned gas in a direct injection engine? I think ECU would stop gas injections before shutting down the engine.

I think clear coats are not a new thing. But manufacturers started to switch to softer clear coats that are more resistant to superficial scratches like swirl marks. The main drawback of such clear coats is that they can easily be damaged if a wax is applied incorrectly. For example applying an...

Probably no deeper than the rear diff snorkel. Unless there are any electronics that hang lower.

Sounds like a conspiracy theory. By the way, water is a solvent. Pretty strong one as well. Don’t drive when it rains.

A nice function of the app is that you can set a destination and send it to the car.

Yeah I don't get the "they are trying to save money" argument. What is the cost of an oil change for Toyota, $50? They can add $200 to the price of the vehicle to cover 4 more extra oil changes and nobody would care.

Couple of days ago, when I started the car, I got a notification on the center screen saying something like "update installed". Since then the jerking/hesitation while coming a stop completely disappeared. I initially didn't pay much attention to the update (I assumed it is a GPS map update or...

The thread on the “other” forum that suggests the noise is coming from the injectors. Author suggests the injectors operate at a much higher pressure at startup when engine is cold and that is the source of the noise. A quick google search suggests it is common for direct injection engines to...

Looks like not letting the hybrid battery directly power the cars electronics is a safety choice. But based on the article below, some manufacturers like Hyundai integrated a “push-button” to jump 12v battery using the hybrid battery. I wish Toyota also added that as an option...

They actually advise against warming the engine.

To be honest, I am not sure. Heavier tires have an effect on MPG if you do a lot of stop and go (and need to spin up heavier wheels), but with an hybrid that energy spent to spin the wheel would be mostly recouped by regenerative breaking. What has a stronger influence on MPG is tread pattern...

The big metal box at the right back corner of the engine bay (that the orange cables connect into) is the "inverter with converter assembly" that, among other things, charges 12v battery from the hybrid battery. Video below explains this around 2.30 min mark.

Not really. It is not a design problem. Engines that they manufacture in Japan are fine. It is the US factories that have issues which historically has always been the case and the reason why people preferred Japanese made models. The issue with the turbo V6 was mainly the debris form the...

They can potentially optimize their software to run better, assuming that there is still room to grow. I don’t think hardware swap would be possible considering how integrated the electronics of the car is.

I wish they installed a faster computer for the center and instrument cluster screens. The screens are laggy, and while it is a minor annoyance, there is no excuse to have laggy screens on any device in 2024. An adequately fast computer would probably not cost more than $50 compared to what they...

You need to turn on widgets(if I am remembering the name correctly) after selecting 1-dial cluster.

They are reinforced. There is not much info on them, but they are sold in Australia for “severe” off-roading. What everyone considers severe off-roading is different though, and no tire performs great for all conditions. Like AT tires with very aggressive threads have great deep snow...

Thank you just saw it. It was hiding in plain sight :).

Anyone knows if the spare tire also has TPMS? I don’t see the spare pressure in app or in the car.

Actually it is the dealers not deflating the tires during the release inspection. Manufactures ship cars with much higher tire pressure to prevent flat spotting during transport as the car sits in the exact spot on the tire for many weeks. Dealers keep this pressure as their cars also sit on the...

Yes. Seems to get better after engine heats up.

I have these 3 set as my screens. I switch in between based on what I am interested see at that moment.

I am sure Toyota could have made an LC with 30-35 MPG if they tuned the engine and hybrid system solely for efficiency. But then people would complain that it has no "kick" and feels sluggish. So I am happy with what we got.

I am sure people will come up with mods that allow engaging 4wd low with center diff unlocked. At least in tacoma, people figures out how to engage rear diff lock in 4wd HI.
