15w40 in 3urfe (2 Viewers)

[2021 LC200]

i am not am engineer and do not play one on tv

that said - 200 isnt the only thing that “revs up”
on start up. We have many other toyota/lexus products in our fleet and all do the same thing

now given we have 400-500k mile on many of these examples in our personal fleet I think people are right

toyota engineers are dummies

had they not done these engine rev up on start up - i bet we could get millions of miles instead of reliable 500k miles

Exactly

I just don’t know what I’m gunna do in 95 years when my 200 hits 1,000,000 miles and the engine fails.

Actually, I’m not sure what my grand children will do since I’m dead

Interesting enough, the body does not rust in Texas and I keep it parked at home and at work covered/no direct sunlight, so a Land Cruiser with a well running engine at high mileage in say 50 years could be quite a collectors item.

Same with mine but, when I do drive it it usually gets beat up.

OK, so the consensus here is that no one uses 15w40 oil in their LC200?

 

[2021 LC200]

I would say consensus is a big word when discussing oil viscosity for our 3UR-FE... Seems indeed no MUD 200 owners run 15W40.

What I have learned from considering oil viscosity again and by reading up on Tundra forums is that high initial cold start rpm requires thinner oil at colder conditions. Considering start up and the way Toyota manages this points to 0W or 5W and not 15 or 20W. In order to meet your interest to increase viscosity at operating condition I can see using a 40, therefore 0W40 or 5W40.

Taking oil samples with the current oil you run and monitor the trends post a viscosity change would be an option to understand any improvement or adverse effects.

Another way is to use 5W30 and not worry about it anymore.

Yeah I agree. I see no need for 15w40 or 20w50, unless you are a courier in the middle east, or wheel in death valley

 

[skrypj]

will the engine blow up with 15w-40, no. Unless you are cold starting it at low temps then maybe it will be an issue.

But I think pretty much everyone said there are better oils. 0W-40 if you insist on a 40. Even a 10W-30 would probably be a better option.

Will it be subject to the death tax?

What I do not get from an engine wear perspective is why Toyota programmed the ECU to rev high at a cold start (initial at ~1500 and settlng at 1200 rpm, then a minutes later drops below 1000) other than cat heat up and again… emissions I would think.

My 535d inline 6 starts and revs immediately at 600 to 700, like many V8’s used to do as well. I wonder with the ECU tuning now possible (would have to search for the thread), this feature can be programmed out or maybe with a lower initial rev target.

Because a quick light off of the Cat is the primary concern for US emissions testing, engine longitivtiy be damned.
