After running out of fuel recently I have decided to keep track of my actual MPG for practicality sake and for curiosity. I am in the process of repairing and making my Fuel level gauge accurate as well. My first refill since recording the mileage after the previous top up has me getting 28.8 MPG in my Special Edition suby converted Fiberfab Speedster. The engine and ECU are the same as the 2007 Impreza, the official fuel economy shown for the Impreza is : City 19-23 Hwy 25-29. My car is lighter of course and not powering all 4 wheels and an extra transfer case so it seems reasonable for me to be getting 28.8 MPG. All the driving during this time was on rural Hwy. and light city, no expressway, Just thought I would share this info. and a few pics of my car for the one or two newer members that haven't seen it,,LOL.

Very cool Jimmy. After I ran out a couple times in my original Spyder, I carried a 1 gallon can in the frunk, full of course!

In a Spyder with the stock Bug tank, you can't fill it all the way with the center cap. I get about 160 miles on a tank on the highway. I get about 130 miles around town and doing a lot of "brapping".

I think one ride to Carlisle maintaining 80 I calculated 32mpg. But it usually ranges around 22-25. It will go down to 18 if I'm really on it, banging off the rev limiter at every shift.

I have an EJ255 turbo in my coupe, with a (supposedly) 16-gallon fuel cell, which physically measures 14+ gallons.  On a road trip, I get low 30's (32-33 mpg), low-mid 20's around town.  When I first got the car, I would routinely travel with a 1-gallon plastic gas container, secured in the frunk, until I learned how to read the fuel gauge.  I never felt comfortable with a portable fuel container, and stopped carrying it within a few weeks.   

I notice a few people carry some extra fuel with them in case of emergencies. Has anyone tried the engineered fuel available from Home Depot in their cars? When you click the link disregard the $71.00 four pack price. It is available by the single gallon. I use it in all of my lawn equipment that isn't 2-cycle and the stuff works very well. Equipment starts easier than with pump gas. I also use the TruFuel 2-cycle stuff and that also works extremely well in my 2-cycle equipment. Especially since it can sit for weeks between uses.

As you know @Robert M, I'm a Midwestern hick-town hard-head.

The idea of paying nearly $20/gal for gas has always stuck in my craw, and I refused to do it-- even when the best man in my wedding (who now owns outdoor power equipment centers in 4 towns) recommended it for my 2-stroke Stihl trimmers, tillers, edgers, blowers, etc.

Instead, I'd buy a freaking carburetor for at least 50% of my eleventy-billion little engines every single year. Finally, a couple of years ago, I relented and bought a couple of gallons of 2-stroke "snooty-gas". I've not replaced a carb since. I steel myself and buy it whenever I'm feeling rich and famous now.

I don't do it for the 4-strokes though. For the mower, snow-blower, pressure washer, etc. I get gas from the one local ethanol-free station-- I buy 93 octane and add Sta-Bil, whether it's winter or not. And do you know what? I don't have any carb problems with those either.

If I were carrying an extra gallon for emergencies (and I don't, because I have a working trip odometer), it'd be a gallon of the same elixir, because I'm a tightwad and the $10+/gallon would really stick in my craw. What would invariably happen would that gallon of gas would ride up there for 5 years... and by the time I really needed it, it'd smell like turpentine and have the consistency and color of rancid honey.

What you're proposing has merit, should one feel the need to carry emergency gasoline.

I’m with you on all that Stan but here in Kommie-fornia ethanol free isn’t an option unless we buy race fuel and that’s a lot more money. I offered this as an option because being engineered fuel it’s supposed to last a long time without going bad. I use my trip odometer as well but I’ve pushed it a few times and guessed wrong. Lol

We're lucky here re: ethanol. We live in the southernmost part of the county. It still allows ethanol-free gas, albeit 91 octane. I run this in ALL my lawn equipment and in my Bimmer bike. They ALL get Stabil in the fall. 

The Spyder gets 93 octane Sunoco with the unfortunate ethanol, and also Stabil in the fall.

I've replaced exactly zero carburetors and had exactly zero problems.

Unless you want to count the 24 year-old chainsaw that eventually ate it's lines. I replaced the lines($7 lines, filter, clunk, air filter foam, and a spark plug). I got no joy, then tossed it. It had a LONG and hard life of occasional use and putting it away wet. The replacement is fancy, it has rubber engine mounts, to keep me from shaking I guess.

There is zero chance of me buying a $20 gallon in a can.

I am able to buy Shell premium up here, with zero ethanol.  I use that in the Speedster and my leased Subaru STI.  If there were a station closer, I would also use it in all my lawn equipment. 

So far, no issues with lawnmowers, weed eaters, chain saw, etc. using ordinary premium fuel.  I drain the fuel out of these items each time they are put away for the winter.
