The Car Care Nut Gen3 two year review

I agree with many here, I love my 23 Hybrid. I'm not getting all bent outta shape because I have a .1% change of the engine blowing up. Probably about the same odds as just going out and driving the Tundra and getting in an accident. A .1% chance of getting in an accident wouldn't stop me from jumping in and driving. People are so irrational.

 

.01% chance? Where did that number come from?

 

I have heard it on my 6th gen 4runner when in the garage.

 

As you can see earlier in the sentence, I meant .1%.

Of course I was just trying to make a point... in truth the chance is .3% so damn.. I was a bit off.

So lets elaborate a bit more on this for you peoplez not mathz inclined

If Toyota sold 450K Tundra's and 1350 of them have blown engines then that is .3%

Again, you probably have a better chance of getting in a wreck and dying every time you drive your Tundra then that and I dont see ya not driving it.

 

More mythical numbers.

This has been discussed numerous times.

 

At this point it almost feels like they post the mythical numbers just to elicit a response from you

 

The rear end was made by Hino, and I would assume it's shipped to Toyota dry. So I would place the blame on Hino factory workers myself. Now recently they have changed suppliers (from what I've heard anyway), so may no longer be Hino. IDK
I think a 10k mile dump is plenty early enough, so a 2k dump is not necessary IMO.
I tow with my truck quite a bit, and will do a 10k dump.
Good practice on the early oil changes, of which I've done the same. Currently 5k on the clock and it's had 2 changes.

 

Here’s the weird metal crap that came out of the rear differential of my 2019 on its first fluid change around 60k miles

 

That's pretty bad I would say. I think in most cases, the magnet has done its job. You just hope it caught everything! I mean, it is there for a reason.
Any problems with yours at all?

 

Zero problems. Many, many reports of metal on the magnet at first diff fluid change.

 

I was thinking about this while watching the TCCN video. His initial reaction was the fluid looked fine, then he spotted the 3 metal chunks stuck to the magnet. If that was manufacturing debris, and not actual gear material, chances are good it would have stayed on the magnet and never created any problems. Obviously, it's not what you want to see, but I wouldn't be too alarmed over it.

Now, if he finds similar metal chunks on his next fluid change, that would be more alarming to me.

 

My '26's engine failed @ 9300 miles... i had rattles, squeaks and all kinds of issues... They are nicknamed the TurdGen for a reason.

 

I had mine changed out early - i think around 2400 miles... for that reason as well as the gear whine i was hearing on the highway. It went away after the diff fluid and tcase fluid changes. I paid for that out of pocket because I didn't want the hassle of the back and forth. Fix the quality issues - address the V35A issue and it would be a great truck. TSS3.0 would be nice - but i'd rather they spent all their "refresh" budget on addressing quality issues.

 

It was a pretty naive statement he made for sure. I know of 3 (mine included) that have had engine failure.

 

none to me, let it grenade and they can warranty it, I’m not paying these stupid things at 5-10k miles lol

 

I just find these convos on maintenance interesting. I’ve done 3 million-mile Tundra owner videos and not a single one of them did any additional maintenance or oil changes sooner than the recommended 10k mile interval. Yet, people will make all sort of claims about how that doesn’t apply to them or some other reason.

Oh and there are thousands of examples of turbocharged engines going similar miles without issues from many other brands. Just because it has a turbo, doesn’t mean it has a drastic change to the maintenance interval.

 

But it probably should. Forced induction motors (especially turbos) create a different operating environment for the motor and its components and fluids.

 

I’ve heard that argument for 15 years now and we see hundreds of thousands of miles on turbocharged engines without issues on the vast majority of them.

 

And the funny thing is, Toyota's maintenance schedule doesn't even list diff fluid changes as normally required at any mileage. It's inspect only, unless you have Special Operating Conditions.

I've traded in 2 Tundras with north of 130K miles, and neither one ever had the diff fluid changed. LOL.

 

If your driving habits dictate longer intervals, fine but if you're short tripping then not so much. Don't expect the motor to last if you don't adjust accordingly.

 

After seeing the oil he drained out, I would be changing oil & filter every 3 to 4 thousand.

 

yards, not miles.

oil = cheap

 

So ... here's my personal view on these modern engines. I've expressed my concern and opinion on this matter before. Bear in mind this post doesn't necessarily reflect on everything, or anything, what Ahmed discussed about in the video, nor what everybody has said so far in this thread. Also, this doesn't only include the infamous and our beloved V35A engine, but many modern Toyota engines, and others for that matter. The science behind of extracting every possible millimeter-metric of power, reaching for that high thermal efficiency, delivering the most of in terms of fuel consumption and economy, and with these thinned out oil and tighter tolerances of assembled parts - you're simply asking a whole lot of demand from these engines to deliver that optimal performances in any given condition. Upon seeing how crude that oil looked as soon as he started draining, it just looked like a 10,000 mile oil change rather than a 2-3000 mile oil change. And, it being a Hybrid, it's ridiculous that it's already that black this early on. Sure, driving conditions and how he uses his vehicle is one thing, but it's still just way too early to see oil turning this hollow-deep black. I've seen what cylinder walls looked like on a really low mileage A25 engine juxtaposed to a really high mileage 2UZ engine. While one engine appeared to have light vertical lines that's clearly visible but hard to feel it with finger nails, the other still retained that mint factory finish cross-hatching like it had just rolled off the assembly line. I will let you guess which one fared better. One engine uses the 0W16 graded oil while the other uses 5W30. I think it is inevitable that it's best to not stick with these long term interval oil changes anymore, but now reduce it down to at least 5000 mile oil changes. Turbo or not, it not matters. The sooner the better. This would be my personal advice.

 

FYI the hybrids ICE starts every time the button is pushed, and considering how often the truck was only started and shutdown. I can see why the oil was so bad.
I'll bet it smelt like fuel big time as well, and leads me to believe that fuel delusion is a huge concern with most engines. Especially using a low viscosity oil.

 

I'm aware of that. It's just the running times of engine between a Hybrid and a non-Hybrid. Still, too early to see it turning dark like black coffee.

 

I cant imagine needing to pay someo

Million mile drivers are on the highway going the same speed that entire time. That isnt a good comparison for the maintenance intervals of oil changes.

 

The color of that oil was bad after the short miles he put on it. I wonder how much of that time was sitting and idling. I’m betting a bunch. That oil probably had far more running time than the miles suggest.

 

I always thought running hours/minutes were a more accurate indicator than mileage (for engine use atleast anyway).

Doesn't matter that engine is running for considerable periods of time - and they do pull over and idle them to take breaks/rest - some of that is also making it into city/in-town traffic to drop off/pickup loads. Not to mention stop and go traffic.... If you are driving those distances the vehicle is also see'ing rapid drops in temperature - from say TX heat to colder temps up north... I wouldn't down play that.

 

I remember years back - with the 3.5s people were claiming that setting up a oil seperator helped keep their oil cleaner between oil changes... not sure how true that is or not... I paid it no mine - drove mine to well beyond 200k miles .. 100% factory stock engine. I think I replaced the plugs once... otherwise - 3k miles oil changes (used only mobil 1 back then + oem oil filter (FL500S filter)) I don't think i even replaced the water pump on it - every year - full coolant replacement, don't recall if i ever replaced the serpentine belt. That was also a DI only engine - didn't have any crusty intake ports etc (atleast if it was - it didn't impact performance... etc). Turbochargers don't mean death sentence. My '12 X5 35d still has the factory sequential turbos (more like compounds) with ridiculously complicated actuators (and vaccum routing) etc - still on original turbos ... original injectors - and its hit a pothole since it had 80k miles - its coming up at around 200k miles now - original transmission/transfer case etc. Again turbochargers don't mean death sentence. By comparison my new Tacoma is a cakewalk to work on. I will say the V35As look like a massive pain in the ass to do anything other than basic maintenance on.

Whatever issues the V35A has/had - it is not because its turbocharged .... I'd suspect even if that engine was running N/A it would still be having issues.

 

It absolutely DOES matter. Hi engine oil temps are essential for extended life of the oil. Contaminants such as moisture and fuel are number one killers of the lubricating properties within the add pack.
Even though you stop with idle time, etc... the higher oil temps have already burnt off the moisture and fuel.
Hiway miles are much easier on an engine. You should know that. Come on man.
