Do you use premium gas?

Are you talking about E10 vs E15, or E10 vs Pure gas?

Around here Pure gas (ethanol free) is at least $1 more per gallon, and it is a pain to find.

 

I was commenting on the e15.

But yes nonethanol is more $$$

By the same metric $15 more on a tank of fuel to have your truck make more power and not run like azzz for a week sounds like a much better proposal to me.

I didnt spend $53k on a turbocharged truck so I can nickel my way to an extra $3 per week by using the minimum required grade of fuel.

I think these engines just retard ignition or something to save the motor from crap fuel and the Toyota marketing department.

11:1 compression and 15psi is what it is. You either know or you dont.

I dont care what the manual says. It's just more marketing to help cheap people justify the purchase.

 

Problem with ethanol is long term storage, more than a month. Small engines are stored off season. People with sports car they store in the winter, same thing.

 

Dont forget, no ethanol=higher mpgs or atleast thats from my own experiences

 

How is that 6mt with the new turbo engine? Have you had any other manuals in a tacoma? I'm seriously considering moving to a new one but I need to drive one first.

 

Ethanol will make significantly more power, especially on boosted engines. It's just less power dense so you need more of it but E85 will make a ton more power than 93 and even race gas.

They can get away with high compression and boost because of DI. Its hard to have detonation when there's no fuel in the cylinder to detonate.

 

I did in my 2019 Ford Eco-Boost (Turbocharged). It made a noticeable difference. Worst case scenario it broke even with the increased cost but also increased mileage. Best case scenario, I saved a few bucks actually. Not enough to retire on or anything but hey, $5 is $5. I especially liked it for Road Trips because it extended my Fuel Stops and on the free way was where I really saw the biggest gains anyway. Also liked running that Lucas Upper Engine Lube on Road Trips but getting it in the tank was rarely convenient to when I was packing and departing so it only happened a few times when I was smart enough to buy a few bottles and keep them at the house.

Also run it in the wife's 2021 Supra (Turbocharged). It makes a BIG difference in that car. Have yet to run the Upper Engine Lube on that one. But premium really sets it off. Especially when you disable all of the nannies and squeeze that skinny pedal. Coming back from Santa Fe one Christmas, we stopped at a gas station that had a nice long down hill slope entrance ramp back to the freeway. While the wife was inside getting snacks, I went through all the menu options and turned off all of the little gizmos and widgets that control the car. I WANTED TO LIVE! And I did - going sideways down the entrance ramp. First gear put me into a little drift as I rounded the corner to get on the entrance ramp, and shifting to second or third really broke what traction I had left and it was all hells-bells from that point on. Let off the gas pedal at the last minute, car snapped back in line and we entered the free way facing the right direction and at speed.

I'm not a 4G Driver (so don't hate me) But I tried premium octane in the NA V-6 for a stretch. No consistent noticeable gain. Sometimes maybe yes, a little. Other times nope. But I think I have an issue because I'm getting like 14 to 15 MPG. It keeps falling off. Stock truck too. Coming up on 15,000 Mile Service.

So I say all that to say this. Premium or higher octane really performs well under pressure - and by pressure I mean higher combustion ratio engines. If you have a 4G Taco, then you are running a Turbo and will likely see those gains. Is it enough to offset the cost? That all depends.

 

The 6mt is great- playing with the shifter and the turbo makes 100 mph come up real fast- for a Tacoma anyway… it’s not a sports car but unlike any previous Tacoma you can drive aggressively if you want to as opposed to being a complacent driver.

I had a 2009 2.7 4x4 with the 5speed before this 24 and I’d say the shifter is comparable with an extra gear

I’d say that if you drove a new one you’ll probably buy it

 

I’m pretty sure you just have the opportunity to make significantly more power because of the higher octane making it a more stable fuel to resist detonation from higher compression.

It’s not the ethanol making the power, it’s the compression or the potentially elevated boost from an e85 tune that’s making the power

There’s less energy in ethanol than gasoline so it’s not going to work better on a stock vehicle

I didn’t think about the DI allowing higher compression because the fuel isn’t in the cylinder yet though. That’s a pretty good insight

 

It makes more power than race gas despite having a lower octane rating; especially in boosted cars. E85 contains oxygen and cools better than gas. Thats the reason its making more power, not the octane. Engine Masters has two really good episodes about it.

E85 being less power dense doesn't mean it wont work better on a stock car. You just need to run more of it... about the only thing gas does better is MPGs.

 

People often equate High Octane with High Power - They are different.

Octane is a measure of Fuel's resistance to burning, or pre-ignition.
Since high octane was used in high compression engines (where you needed to control pre-ignition clatter) people equate power to high octane.

But even Ford and Toyota provide HP/TQ numbers based on Octane Level.

Supra HP - Notice the grey box at the bottom.


* Ratings achieved using the required premium unleaded gasoline with an octane rating of 93 or higher for GR Supra 3.0.
If premium fuel not used, performance will decrease.

 

Five pages and no one posted this. Disappointing.

 

Really? I’m definitely going to try this. There’s a station near home with ethanol free gas and I’m only averaging 19.5 mpg on 87

 

Used to work in upstream and downstream industries etc...

Shell V Power. The best. The end.

Exxon Mobile sells the best regular. BP in the middle. Costco in 4th place.

It's about the amount of detergents that keep your engine clean.

 

What about Chevron with Techron - I have always heard how faaaAAAaaabulos it is. Live up to the hype?

 

I fuel at Costco………fill it with Premium for the cost of Regular at an any other station…………same money, better performance……

 

I fill her up with whatever I drive by and also the lowest. Sometimes Costco, sometimes Shell sometimes Marathon. I just don’t get worked up over fuel in this truck. When driving our high performance cars or cars that have to have premium then I would use premium but again not always from the same brand.

 

The Tacoma does run slightly better with 93 octane. Less low end rattle, too. But it’s going to cost an extra $9 per tank. Not sure it’s worth it.

 

Yeah I am sure you are correct. It is my DD and work truck so I just don't find the value. Not that $9 is going to hurt at all I just don't see that much of a difference to bother so I just run cheapest and whatever is convenient to fill up. I rarely am running low at the same place. I am also rarely "getting on it" to even notice unless I am trying to get up to speed on the interstate.

 

Fill the truck with 87 and the car with 93 from Sunoco top tier fuels.
