What octane are u running ?

I use Av Gas from the local airport. Runs like a Spotted Ape.

 

That article is complete nonsense. Lower "octane" requirements at high altitudes have NOTHING to do with having a carburetor vs injector. What it has to do with, is AIR PRESSURE. The higher up you go, the LOWER THE AIR PRESSURE. Computer controls do NOT change the air pressure! Lower air pressure, means less air, which means lower compression, which means lower octane.

The only place where this does not hold true is in engines with forced induction. I.e., turbo/supercharger. Forced induction engines compensate for the lower ambient pressure, and thus MUST adhere to the same fuel requirements, regardless of elevation.

 

Is 87 non ethanol better for our trucks than 91-93 ethanol?

 

Don't let your truck drink and drive.

 

Lol

 

Curious, are you getting the virgin elf to drink the alcohol before punching him in the face to extract the blood into your tank?

 

I found that by adding them separately is more efficient. That little elf bastard hates virgin blood.

 

I'm 100% convinced that you could drive 100 tacoma's and they'd drive 90 different ways. My truck is absolute garbage on regular fuel. That doesn't mean yours is as well. I'm very jealous of your truck. My truck on regular fuel at light load and light throttle feels like you are running on 5 cylinders, or driving over rumble strips. If your truck suffered the same you'd notice.

 

Aviation fuel has chemicals in it that will rot O-rings, gaskets etc... hard on injectors and pumps. Would not recommend.

 

Glad it's not just me!

 

I fill 87, also did for my 01 Taco which lasted 220k miles, still ran like a champ after selling it. If I wanna spoil her, I'll think about using 89 haha!

 

Yeah, the Vacaville Costco is $3.09 for 87 and $3.29 for 91

 

Modern fuel-injected engines could easily compensate for lower air density by injecting less fuel, thus if you're running a low-octane fuel like 85 or 86, you could be effectively running "lean of peak." Every engine these days has a mass-air-flow sensor (which would be sufficient to detect altitude air density loss) but many also have a barometric sensor.

 

If you are using a higher octane gas than the Operating manual calls for, you are wasting money.

 

YOU would be wasting YOUR money on 93. I wouldn't waste mine on 87...personnel preference FTW

 

I gave up on 85/87 and switched permanently to 91+. Get 11-22mpg, depending on whether it's 4-Low fence lines or Hwy miles. No complaints about power, shifting, etc. with premium gas.

 

Sir you are a gentleman and a scholar you said it better than I ever could

 

At that price I don't think it matters. Like others said, we pay double that in ca.

 

I was honestly surprised... I only paid $3.99 at a sinclair for 91 in Ca
First time trying sinclaire, no issues yet.

 

AVGAS still contains Lead, plus it has different Vapor Pressure Specifications.
