It’s official, the 2023 is the Tacoma to have

You are wrong, I've had a number of turbocharged cars over the years and all of them have made it well past 150,000 miles with zero engine issues; two of them made it over 200,000 miles, and all of them were still running great when I sold them. That said, my experience is irrelevant; what is relevant is the modern metallurgy, modern engine design, modern engine controls, and high quality synthetic oils; with all of those things working in Toyota's favor, the only reason why the new engine will have long term reliability issues if they screw up big time.

 

Higher internal pressure, oil temp, water temp, and those dangerous low friction rings for mpgs have led us to…*checks notes* far better reliability than when we had engines without those things?

And by this i mean: We’re running high compression 6cyls at extremely lean mixtures with super thin oil and low tension rings at higher than ever temperatures and all the other things our parents were afraid of…and here we are proudly proclaiming our 3rd gens to be god’s gift. Maybe we can just let the thing even come out before condemning it to the scrap heap of history.

 

If referencing the video he did not say that the turbos were bad, he did not relegate it to the scrap heap of history, actually it had a few tips for those interested in ways that you can help extend the life of the turbo. He also said that the reliability gap is narrowing because of the some of the same things you mentioned.

 

I think the point you missed is the advice he is giving on extending the life of the turbo is about 40 years out of date.

 

So your saying more frequent oil changes (5K intervals) instead of the 10K recommendation that is spec'd for every toyota no matter what engine configuration it has will do nothing to help extending the life of the turbo charger? You are saying fresh oil does nothing for a turbo charger?

You are saying its not a good idea to let a turbo cool a bit before shutting it off since it doesn't matter anymore? It's interesting that manufactures actually include technology with some turbos to do just that, to keep ignorant customers from cooking their turbo's prematurely. I guess they don't need to do that anymore.

Interesting...

 

You do understand we're talking about using high quality synthetic oil and a turbocharger which features water cooled bearings, right?

 

You sure its not both water and oil cooled?....water cooled coming into play more for the after you shut it down cooling.

 

I'm not saying the guy was wrong about everything he said, but some of it was misguided or downright bad advice imo.

Change the oil however much you want, it won't hurt anything. But you can never know if changing out perfectly good oil actually contributed to longevity. Having an engine go the distance (200k+) is such a crapshoot. You could change the oil every 3k miles and an unknowable microscopic manufacturing defect can grenade the whole engine at any time.

As far as cool down goes, sure if you just pulled a heavy load up a grade and immediately came into a rest stop, might be a good idea to let it idle a bit. That would be true for a NA engine as well. For the other 99% of your driving, you don't need to be idling in the grocery store parking lot waiting for your turbo to "cool down".

In a manual transmission, I'd argue digging deep into the throttle to maintain speed vs a downshift is going to put more stress on your engine.

Bottom line is everything that was good operating practice for NA engines is also true for turbo engines and vice-versa. There really isn't anything special going on.

 

Argh, you are taking it too literally, ALL bearings of ALL turbosuperchargers since the very beginning are lubricated and cooled by oil while the engine is running, that is a given. What I'm talking about is the water cooled bearing feature added to commercially available units by Garrett Airesearch back in the early 1980s; the water cooling addition was designed specifically to keep the bearings cool (and prevent coking) after the engine was shut down and the flow of oil stopped. Like I said, the advice from the dude who made that video was easily 40 years out of date.

 

So the oil is still used, and I would assume higher temps and more strain on the oil therefore the advice to change the oil at 5K intervals is not that outrageous at all. He recommends 5k OCI on normal Toyota engines so not surprising that the turbo motor gets the same advice. He covers the water cooling on normal operation with the new technology, I don't think its bad advice to mention if you are wringing the motors neck that its not a terrible idea to give it a minute or two before shutting off the motor.

Seems to be pretty familiar with this new motor to me, This model should be pretty similar.

Volvo has been making turbo-charged engines since the early '80's and added water-cooled turbo bearings early on. This eliminated the need to allow them to spin down and idle the engine engine so the oil wouldn't cook in the bearing after shutdown and ruin it. They had oil jets under the pistons to cool the skirts, sodium-filled valves and other goodies specific to the turbo engines. All you really had to do was change the oil and filter religiously as per spec and just drive them. Turbo problems were rare.

Many aircraft engines are Turbo and Super charged (going all the way back to WWII in military aircraft) and I don't worry about a turbo exploding in flight. I worry more about bird strikes than just about anything else.

 

All of your assumptions are based upon urban legend and are utterly irrelevant. The fact is, assuming an appropriate oil capacity, the oil in a a turbocharged engine will not run any hotter than a normally aspirated engine.

 

How many people pull a hill at full throttle and then shut down immediately? Just the time spent coming into your neighborhood or into a parking lot is more than enough to cool down the turbo. It’s almost never an issue at all

 

Do you think you need to keep a closer eye on oil level

 

Ok

 

Why; turbocharged engines don't use anymore oil than a normally aspirated engine.

 

Ok,

BMW says otherwise from the NHTSA site

Might be true for BMW. dunno. But my current 5 cyl turbocharged inter-cooled Volvo S70 uses no oil between changes and it's currently sitting at 175k miles. Oil changes have been between 3-5 thousand miles it's whole life. I put 300k + on two Volvo 245's and 240k on a 745. None of them burned any oil. My Tacoma uses no oil either.

 

And the 5.2 Voodoo uses 1 quart every 1,000 miles, lacking super/turbo charger. Each engine is different.

 

Same with our cx5. Zero oil consumption between changes. Can’t say the same about my 3rz
