I generally don't run to completely E either, some people believe it's hard on the fuel pumps as the motor is no longer submerged in fuel acting as coolant for it. I don't concern myself with that, I just know where gas is cheaper and watch my range so I can make it back there.

Ethanol content can affect your MPG some, E10 has about 4% less BTU's per gallon, some cars follow the energy to mpg curve and will lose 4%. Others don't.

In that study one of the cars they used a 07 Camry 2.4 and ran different ethanol blends and recorded MPG and more. It actually got the best fuel economy running E30.

The expensive premium grades that some companies like to advertise - like Shell's V-power - have been tested here in Belgium, and while they actually do offer a slight MPG advantage, this simply doesn't offset the equally premium price for it.

(Premium petrol works better to reduce MPG, than premium diesel BTW)


If you can get the big brand stuff for the same price, go for it


In Europe, there's also little benefit when running 98 RON instead of 95 RON

Is it true running your tank all the way to empty can bring up sediment deposits into your engine & damage it?
That's what your fuel filter is there for

And there should be much goo at the bottom of the tank anyways .

What's the lowest you feel comfortable running your gas tank to?
I usually fill up whey the light comes on
Sometimes a bit earlier, sometimes a bit later

I don't mind running it down to an estimated 10-20 miles remaining range either

Unless you let it idle for ages, which an ecomodder wouldn't do, you can't run the fuel pump in a very low fuel condition for very long, or you'd run out of fuel

Temps make a big difference. From about 55F and up, my Prius makes summertime MPGs, from 55F and down, winter MPGs - and "winter MPGs" get worse and worse, the colder it gets.

Again, if you go to the garage page and look at some of the vehicles that have been updated for several years, you'll see a pretty clear relationship between fuel economy and the time of year. Warmer is gooder.

As to fuel grade affecting fuel economy, I haven't observed that. Then again I only fill up at about three different places, and always get the cheap stuff so I don't have a lot of scope for comparison.

As to the truck, I think it would run on straight Pabst Blue Ribbon so whatever pisswater fuel I can pour into the tank, it'll deliver some kind of performance.

Shell sucks(happened at several stations in town 3 of 3 stations 3 of 3 arco stations as well what a good scam) i only get 87 US out of the premium 91 octane pump as noted by the timing advancement table drop to 87 level. which is near 0 sometimes negative .

I do go to Chevron or mobil only No where else (unless it's a rental then it does not matter i get the cheapest **** i can find)

with 91 us octane I can see as high as 42 degrees advancement


it's VVT btw

it's normally on summer gas for the 91 oct so it's normally worth it(it's worth 1-2mpg more )


3.399 = 0.183cents per mile(18.5MPG)
3.859= 0.154-0.139 cents per mile (25-27.6MPG)


So regular fuel will cost $4.58-5.05 per gallon (25-27.6MPG equivalent. )


the inverse is at 2.89 a gallon at shown prices above

I only run the heat if I have a passenger, my car is overheating, or my windows are fogging up.

I used to have other problems in Phoenix.

The worst I can get is in city traffic with lots of stop & go traffic, poor traffic light sequences & heavy congestion yields sub 5 MPG. Avg overall is mid 20s mpg.

Not sure what I can do to net gains. I inflate my tires 1-2 psi above the door jam 35 PSI recommendation. Sidewall max PSI is 51. I hope to not induce premature tire wear by exceeding the manufacturers PSI rating. .

How accurate is the Toyota MPG screen?
Honestly it's very dangerous to run a 51 max psi tire at 33psi
it's under inflated

you can have a blow out


as you can see on this tire it's at 32psi Riding the side wall it wore the corners of the tire.

about 40% side wall compression Hot PSI was 36
I put it to 45PSI HOT PSI is 45 0% fuel lost to heat
