High octane gas only for Hybrid 4Runner?

[Clodydeloady]

My next question is: will the i-Force Max Hybrid 4Runner take High Octane gas only like the LC ?

I don't know why the LC is 91 octane only, but it is not that way for the Tacoma hybrid. The Tacoma hybrid is 87 Octane or higher. Specifically called out in the hybrid manual. Same as virtually every other non-luxury vehicle. Very strange that it would be different for the exact same engine. There must be something specific to the tuning going on.

I would expect the 4Runner to line up with the Tacoma much more than the Land Cruiser.

LC taking premium, 91 min or higher is correct. Something about it being a luxury vehicle. I pulled this screenshot from the LC forums.

So....I am hopeful that 4R doesn't follow the same way.

Yeah, I edited my post earlier, but I had not seen your reply to it. This is just strange to me. Why would the same engine with the same power ratings (346 hp and 465 lb.-ft) require different octane gas? Tacoma hybrid clearly states 87 in the manual (pg 591 BTW). What is different?

It is all in the branding, hey I drive a LC and need Premium fuel! You are only in a Tacoma and regular gas will do!

There is a post on the Land Cruiser forum in regard to demanding premium fuel, and a response from a Toyota employee. According to this "insider", who has contacts with the engineering/design team, the LC will accommodate regular fuel, and adjust accordingly, albeit with a tad less performance and fuel economy. Sounds reasonable to me. Undoubtedly Toyota had a MPG goal in mind for the LC, and this is how it was achieved.

Was this for a 2024 LC? If it wasn't I wonder if there are design differences.

Yes, the 2024 LC. Attempting to locate the post. Possibly it was taken down, as he was sharing non-public information.

Doesn’t matter about a he said/ she said. If the door and manual say premium fuel only. Then I ain’t about to gamble my warranty. Are you?

I would probably need further corroborating information, such as how the system can adjust for fuel octane. Most modern engines have knock sensors, etc. The fuel door says "Premium Fuel", but does not specify an octane value. The owners manual recommends 91 for "optimum engine performance", but does not have any other cautions, such as voiding the warranty or causing damage.

"Select premium unleaded
gasoline with an octane rating
of 91 (Research Octane Number
96) or higher required for
optimum engine performance
and fuel economy."

It’s your dime do as you may. I for one won’t trust that argument on a warranty battle. Not for thousands of dollars for an engine replacement .
Peace and good luck.

Congrats Toyota. You got one more mpg on the highway. Same for the others.

...yes I know it isn't apples to apples.
