As far as my MPG, since I use this vehicle for 4-6 hour work commutes and travel, I avg. 36-37 mpg driving in hilly/mountain terrain (75-78 mph). I believe I could hit 40 mpg on flatter roads, driving lower speeds. With that said, I'm happy with my performance but always looking to increase mpg. I'm planning on changing the spark plugs and cleaning the fuel injectors. Maybe that will increase my gas mileage.

My average MPG is between 28 and 32, with a constant mix of city, hills, and highway miles.

The lowest I have ever gotten is 21, and the best I ever get is 36.

This is in Northern California.

Winter just began in Germany. I usually get around 35 mpg in the summer. In the winter I get around 31. There is lots of city driving in my mix thought. Like 90%.

Went from 34mpg mostly highway to 28-30mpg mainly city driving. 34mpg was with 12 mile one way routes and 28-30mpg is with 5-6 mile one way routes. I had purchased some Denso spark plugs off ebay a couple years ago when I also changed my route, so I'm not sure if it's done anything to my mpg since I recently read that many spark plugs on ebay are actually counterfeit. I'll need to put my old ones back in and see if there's a difference in mpg.

However, driving like a granny from San Francisco to Los Angeles (400+ miles), I'm able to get 40+ mpg. Keep in mind that this includes drafting behind as many trucks as I can find and filling all my tires to above 40 psi with zero braking. Consistent 50-55mph on the freeway. If I drive normally from San Francisco to Los Angeles, I'd get about 30-35mpg (65-75mph). Not sure if there's something wrong with my car as it seems that my car is doing 20-40% worst than everyone else in this forum...

I haven't read all 18 pages. And I'm aware I'm not the first to address this.

I'm shocked that a sticky in the OP encourages people practice not only dangerous (as pointed out) but a costly method of raising mpg. Over inflation of tires. NEVER inflate your tires to what the side wall says. Your tire is designed to fit multiple vehicles with varying air pressures. The sidewall is simply the max the tire can handle. Inside the driver door jam it tells you what Toyota says your tire pressure NEEDS to be. Shockingly, the engineers knew what they were doing when they designed the car.

I've spent 2 years as a tire tech before I was 21.

Not only as someone said there is higher risk of separation. But if you over inflate your tires you are GUARANTEED to wear out your expensive tires prematurely. Since you are putting most of the rolling pressure on the center area of the tread your tires center will go bald fast. Is saving a few bucks at the pump worth spending hundreds more on your tires? Economically it doesn't make sense. And we love better mpg cause of monies. So this just doesn't make sense.

Safety. Since you aren't putting even pressure on your tires footprint you are drastically reducing traction. Your stopping distance is increased. Which may just be the difference between a near miss or a fatal accident in an emergency. Once again, I'd like to point out that the engineers at Toyota knew what they were doing. Shockingly.

If you do want to ignore all the economical and safety reasons not to over inflate your tires here is one more thing to keep in mind. It improves mpg by reducing rolling resistance. Which ONLY in the city. This has been studied. Somewhere between 30-40 mph rolling resistance has a negligible effect on mpg and the only resistance that matters air resistance.

On that note I'd like to encourage forum mods to alter the OP to no longer encourage drivers to practice dangerous and expensive methods just to save a few bucks in the short term.

Greetings from SF! We have similar driving habits, it seems. I probably do ~ 60% of my driving city (SF) & ~ 40% highway.

The worst tank I ever had was 21 MPG, while driving for Lyft in SF, in the winter. (Hope I never hafta go back to that side-gig!)

The best tank: 37 MPG, en route to either LA or Joshua Tree. I was happy as a pig in shit. Also: I drive between 65 & 80 MPH on the highway.

Although I do a mix of driving, I usually average 27 in SF, & 33 highway.

I'd call it ~ 30 MPG overall.

No clue how these lucky bastards on the forum are **averaging** 42 MPG haha!

Hello all, this is my first post. I'm about to but a 1.3 hatch t-spirit. I have experience of the Yaris. I like them a lot but I like all Japanese machines. Having just glimpsed through this thread, I'd thought I'd tell you of an experience I has with a former car, a Ford Mondeo 1.8 diesel (manual transmission). This is a euro car, not the one sold in the USA with the same name.

When I bought it, it became apparent that the dual-mass flywheel was giving up the ghost (with a mere 50,000 - not impressed). The reason why seemed clear - the 1.8 litre engine was a gutless POS and needed a big boot to get anywhere, and the drag starts had killed the flywheel. So did I change the car? No, I changed the flywheel. Obviously.

I drove the car within its limits for another 300,000 miles - painful, boring miles - but my sedate careful pace returned easily 60mpg on the motorway and easily 50mpg around town.

The car eventually expired at 350,000 miles when something called a 'wet belt' snapped (similar to a cam belt but since it ran in an oil bath Ford decided it didn't need maintenance and thus didn't mention it in the service list - curse them). The clutch and flywheel were still good.

I checked tyre pressured when I thought of it. I kept the boot (trunk) mostly clear of junk. I made nice smooth gear changes and didn't rev the tits off it - no point, it had nothing to give - and tried to anticipate braking. I drove everywhere and in all conditions.

Conclusion - your right foot is the biggest factor in achieving high fuel economy. For some this is a an unacceptable truth. Even 30 mph is a lot faster than walking, folks. Also, auto transmissions suck up power and use more fuel than their manual shift equivalent and are used chiefly by lazy witless idiots who can't drive properly.
