assuming I fill up at the SAME pump every time AND assuming that the pump hasn't lost any calibration---hon-day04

Silly me, it's actually a pinned topic!

Here you go.

ECU reset topic

Darn, that wasn't it (but it does help).

Here it is, boy did I have to search!

ECU thread, again.

Actually required to keep that stuff fairly accurate by law. And even between companies the stop point is fairly even, Only Murphy Oil, aka Walmart gas, has a higher thresh hold for stopping, +.5 gals more. Where i can usually get 12.5 +/- .5 gals, Walmart would usually fill to 13. These fills being from gas light on empty.

Here's some food for thought:
When your school has a major engineering program your gonna get the full physics dose at times, and this thread is one of those.

Just filled again, with what I believe is real gas:
Tank # Fuel MPG
1: ....gas 36.6
2: e10+gas 31.0
3: e10+gas 21.9
4: ....gas 31.9

Driving conditions similar for all tanks. Tank 4 has some AC time.

Amazing, the difference between horse piss and gasoline.

I have not done my civic duty in contacting my state legislators.
I have done my car duty in finding a real gas station.

Found this in Marvel Mystery oil forum...It is safe to use Marvel Mystery Oil in every tank of gasoline. In fact, we recommend that you do. Using it in every tankful helps replace the lubricity lost with the addition of ethanol to gasoline. It also improves fuel economy.

Sorry, but E10 gas is not causing your mileage drop. You have way too many uncontrolled variables.

At MOST you would see 1 mpg...more than likely about 6/10 of a mpg.

Gas is gas. Shell is Amoco is BP is Chevron is QT is Texaco is Exxon. They all make gas...put into a system and "cash out" of the system. It is all a marketing game and the FTC has allowed them allot of leeway to sell their wares...

A good analagy is taking a $100 bill and depositing in the bank. In a few days you go to that (or any bank) and withdraw $100 to have a night on the town with the wife. You wont get that $100 out...same for gas companies. BP is selling gas that Exxon refined and vice versa.

There are a few exceptions to the rule, but most of us are running "plain ole' gas".

If you are in the military, thank you for your service.


I'm sorry, but you are wrong. I don't know how you can categorically state that E10 is not responsible for my MPG drop.
This is the third personal car I've used E10 in, and it's had an effect on all three. About a 10% drop in one, a huge drop and significant loss of power in another.

Thanks for your opinion--not fact, opinion--but just because the oil companies or some fed bureaucracy say there's no difference doesn't make it so.
And the 100 dollar bill has nothing to do with anything.

E10 is junk gas, just my opinion based on hard data.

Summertime - 8.4 to 8.8 litres / 100 km.
For the past two tankfuls tried driving at 90 km/hr rather than 100. Not a significant difference.

Wintertime that's about 9~9.5 l/100k.

Cheers - Miles

I regularly receive 36-37mpg communting to and from work. I fill up my gas tank everytime I fill up and use my trip to keep track of the miles on the tank and my last couple fillups have been 37mpg. I've slowed down since tuesday because I'm curious if I can break into the 40s. I will let you know how I do.

On my 13th tank of gas.

Mileage from 22.39 to 28.81 with an average of 25.05 MPG

I live in LA with 40% highway, 60% city driving with A/C on 80% of times.

My GSL with automatic gets from 26 to 31 mixed 70/30, hyway/city. It should do 33-34 on straight hyway at 70 mph.

My 5 speed Accent gets 33 to 39.
