EFI, carb, B3, then modified cars with B6 (Gen 1 & 2, SOHC & DOHC, turbo), B8, BP, auto or manual trans, a multitude of tire sizes... That's quite a bit to crunch. Would you limit your info to the most produced of cars, the EFI 5-speed, or would you go for all factors to find a premium setup?
Would need about 20 data points (fill ups) from each festiva, and at least 10 Festivas in each group (auto carb, manual injected, 1.3, 1.6, etc)
Would be fun though!

Repeating:
With accurate years-long data of 10% ethanol blend use in our 3 cars, & now, 8 months of 100% pure(ethanol-free) gasoline use, have shown an increase of 8%(now up to 8.3%), 7-8% & 5% in our 3 cars.

just a ? - wouldn't adding some octane booster or ______ to reg. gas be as good as puregas? I mean if you end up paying 10-20 bucks more for a tank of gas and could ad a $5 can of addative you'd be better off maybe?Last edited by navdoc101; 06-03-2012, 06:11 PM.

Cool stuff though.......If anyone wants to help me gather data, I would gladly run the statistics for you. It would be cool to come up with a "how much does ethanol effect the gas mileage of a festiva" study. I would gladly admit I was wrong if we found evidence showing it to be so. In fact, I would be happy to say I was wrong, lol.......I love stats!Last edited by DriverOne; 06-03-2012, 04:54 PM.

The cars use different logic for mapping ignition timing and different input logic
from the knock sensor. The knock sensor only retards for poor fuels on some, and
other manufacturers have the knock sensor test the octane of the fuel and adjust the
timing up to the fuels ability to resist knocking.
With so many variables it will be hard to predict the exact outcome for each kind of car.
The Toyota o2 sensor was not able to cope with the extra o2 present with hybrid fuel
in mileage experiments.
With today's engines and technology we should have engines and computer systems
made just for CNG or/and LPG and be burning these fuels at much less cost per mile
and without the destructiveness of the alcohols and hydrogen.

Seems to be a decently run test.
I might have to dive back into my logs and see what my data actually tells me.
Would rather run trials now on 10%ETOH vs real gasoline as I'm not sure my logs from 5-10 yrs ago delineate ethanol vs real gasoline.

You don't consider that actual ethanol engines use much higher compression ratios than gasoline engines to get the most efficiency out of ethanol. Engines designed to get the most efficiency out of gasoline don't have the high compression ratios of ethanol engines. Thus, using ethanol in gasoline engines isn't getting the most efficiency out of ethanol, over & above the btu loss of ethanol compared to gasoline.
