Premium Fuel or not?

[Nuke]

In this video the presenter mentions they found a difference in performance using 87 octane and 91 octane in dyno testing.

Also claims the factory air box on the T24A-FTS is pretty restrictive. The Tacoma uses a slightly different airbox than the LC, the LC airbox is probably even more restrictive.

More interested in economy, not performance. Would be interested in those numbers.

I've been using 87 for a while now, no ill effects at all.

Same here

Any improvements in economy from less restrictive air inlets are usually so small as to be unmeasurable.

Probably the same for different fuel grades since most of us aren’t running around demanding full power to the point octane difference is going to make much more than a small percentage of difference.

I might still end up replacing the stock airbox and boost tubes, along with some tuning. I want more power, but I have no expectations that fuel economy will improve from those efforts.

Not sure what their offering will be, but tests show that less restrictive air filter options, such as K&N, allow markedly more particulates to pass through. As many of us will be using our LC's offroad in dusty conditions, best carefully consider this factor.

At this point I wish the moderators would just lock this and all other similar topics and say "RTFM"...

100% agree. Read the manual. Don't agree? Do what you want, see what happens. Seems pretty straightforward.

Of course, the alternative is, just stop following the threads one finds repetitive or irritating. They eventually fade away. I am still hopeful the issue will be addressed by the individual who posted regarding his personal interaction with Toyota engineering.

Great advice on "do what you want"............... and I'll add....... Don't rag on people who don't agree with you as they have an opinion just as you do.

Truck cost was $70k. I’m not skimping on a few dollars a fill up.
And agree, don’t like the thread, maybe just walk away.

Agree with not censoring content. My only complaint is with redundancy. I think moderators could do a better job and have been remiss on these boards where it comes to pruning and unifying redundant threads. It detracts from the utility of the site and ease of finding relevant information when content is spread amongst 20 redundant threads instead of a unified one. Other boards do a much better job with this while also not censoring content.

 

[EOD Guy]

They should probably get a pay raise to accomplish that, so other than sponsorships, I wonder who would fund that.

 

[Alpha Puppy]

Lots of communities manage to find interested volunteers to manage that, hard to see why this one would be the exception.

I have no plans to run anything with an oiled “filter”. There are plenty of manufacturers who offer dry media filters of OEM quality material in a cone shaped filter that increase the surface area to allow greater flow without sacrificing filtering ability.

What perplexes me is why anyone still uses the oiled filters at all? If you take two well made (from a surface area and flow characteristics) filters one oiled and one dry media; the oiled filter will only out flow the dry filter by maybe 5%. Not enough of an advantage to allow in more particulate for sure.

One time I had an issue with the fuel pump and had to get the entire fuel system replaced in a vehicle. This vehicle was a BMW and required premium gas. They pulled up the history of the last 10 or 15 times I fueled up my car, and the car sensed what kind of gas I put in it every time. Due to this, and them seeing that I use premium gas all the time, they deemed that the damage was not my fault. I don’t want to know what would happen if I required this $30,000 procedure and I wasn’t using premium gas. They probably could’ve used it as a reason to say I was miss using the vehicle or whatever. So for all your cheapskates out there, I’m one of you. I like to be as frugal as possible and not spend money on unnecessary things. But I will never put base gasoline in my land cruiser because if anything ever goes wrong? I don’t want them to use that as a reason, that it was somehow my fault.

I have to imagine with all the tech in vehicles (sensors, storing of data) these days they can determine what fuel is being used. I’m with you on this.

I want to believe my LC power train is bulletproof but in the chance it’s not, and there is a massive failure, I don’t want to give Toyota the opening to wiggle out of their obligation to make things right.

It shall be premium.

Definitely something to pay attention to. That said, I drove about 90k miles with a K&N conical on a snorkel setup with my 2019 Ranger without any issues. I cleaned it and reoiled after each off-roading trip.

I go WAY back, to the oil-bath air cleaners. I wonder how efficient they were? Thing is, that was all there was...

Here’s an interesting exhibit for this discussion. The recently announced 4-Runner, with the same engine, trans, horsepower and torque has a minimum requirement of Regular fuel.
Tuned differently?

Sure wish we could get a definitive answer from Toyota! Precisely the same HP/Torque specs between the LC and 4Runner. Does not compute...

The most logical explanation I’ve seen thus far was a comment on another forum. The user said “I think it goes back to the LC being a "premium" product, and there may be some NVH targets that it won't meet on 87Reg.”

So, assuming Premium fuel will quiet the engine, then the LC would be a quieter ride than the 4Runner.

I seem to remember that the lead engineer of the tacoma (Sheldon something) said in an interview with TRD Jon something to the effect that it's a global platform and they needed to have that as the standard but that he was just speculating.
