So, in an effort to lower gas prices, the government in its wisdom is going to be diluting our gas with even more EtOH.
So a bit less cost per gallon but also fewer MPG. A total con job!! And at a time of global grain shortages.
So, the question is whether we will still have the choice of paying for 93 octane with ONLY 10% EtOH or will this 15% mandate apply across the board?
I know many small appliances and marine engines hate ethanol fuel, but can an F-Type get by with 15% fuel?

 

I am doubtful it will happen at all, at the most not the amounts Joe is saying. If there's a run on ethanol, the price will rise, dimming any possible savings. Name brand stations will have to hang signage and stickers stating content, etc. I don't see it as more than posturing. Does his Corvette run well on e85?

 

Joe can still drive (a Corvette)??

 

My Owner Manual says:

"ETHANOL
This vehicle is not suitable for use with
fuels containing more than 10% ethanol.
Do not use E85 fuels (85% ethanol
content). The equipment necessary for
the use of fuels containing more than
10% ethanol is not fitted to this vehicle.
If E85 fuels are used, serious engine and
fuel system damage will occur.
Fuels containing up to 10% ethanol (grain
alcohol) may be used. Make sure that the fuel
has octane ratings no lower than those
recommended for unleaded fuel. Most drivers
will not notice any operating difference with fuel
containing ethanol. If a difference is detected,
the use of conventional unleaded fuel should
be resumed."

That is for a MY 2015, dunno if it changed for later years or if so when or if it is different for MY 2021 but I very much doubt it.
So if it hasn't changed then 15% ethanol is no good for our F-Types which begs the question, what can you do if all fuel is minimum 15% ethanol?

 

Same for my MY18, Oz.

 

I live in Florida and believe it is unlikely to remove 93 Octane (or other states with 91) as E15 is basically 85 Octane but the Ethanol added brings it back up to around 88 Octane, from what my research has shown. There is no way any F-Type owner should be running this in their car.

It's bad enough here in California that we pay the nation's highest prices for gas and the highest octane available is only 91, but if E15 becomes the only choice I may as well buy a horse. My Mazda CX-5 will run on 87 octane but it gets 15 more HP on 91 octane and the owners manual also warns against using more than 10% ethanol mix. Even my snowblower warns against using E15.

But I suppose the mental midgets that make up the administration in Washington have done zero homework regarding just how few vehicles in the US will run on E15. That doesn't surprise me and I hope their poorly conceived plan is quickly scuttled.

 

 

More ethanol equals less MPG.
More grain for ethanol during a grain shortage equals even higher food prices.
None of this helps us.
Typical political smoke and mirrors.

 

I don't put any ethanol in mine, it costs more, but so be it. I realize some folks can't get real gas, that sucks.

 

I wasn't aware that any of our so called leaders have a plan.for anything.

 

Does anyone know if VAP has an ethanol tune yet, say E30 or so?

 

Not necessarily, no. However with their tunes and IF you have access to non-ethanol gas, you can mix your own ratio to get to a an E20 or E40 mix. With the E20, from the way they've explained it to me, really is going to help during hotter months to help better cool temps, however mostly is going to only help on the recovery after lets say an auto-cross run or drag run, not necessarily add any additional performance. As for running E40, @Terrance39 has a sick setup with a monitoring system to ensure that the right mix of gas is being delivered. You would NEED to have this setup, in order to run E40. I will defer to Terrance to show his setup, but if you search for a thread called, Full Send, I believe he provided details in there.

 

Prices on ethanol-free gas are all over the map...same company (QuikTrip) was 54 cents more in Bastrop than premium while their Conroe location was only a nickel more. Unfortunately, they only have 90 octane for the ethanol-free, but I did see a measured increase in MPG. From Conroe to my office near downtown put the dash indicator just north of 29MPG, and based on what I have seen across nearly 80K miles of driving since I bought this one, I know that means about 28.4-28.5 actual. That is about 3.5-4MPG more than I normally get for a 29 mile drive each way. The increase from the return leaving the Bastrop station made it a break-even sort of proposition, but the nickel difference has me wondering about altering my routine to get up to Conroe more frequently.

However, I have heard reports of a Bucee's near Katy that was pushing six bucks a gallon as recently as last week for 90 and 92 octane...THAT is a price that I would have challenges tolerating.

 

This went exactly as expected - why did I expect anything different...

If VAP is developing an ethanol tune, that strongly suggests that all fuel components in the F-Type are ethanol compliant. If that's true, then what's wrong with E15? I can only guess that it'll slightly lean out the fuel mixture, and probably by very little, assuming that ECU makes adjustments. I hope VAP pops in and explains what happens if E15 is put into a stock untuned car. I kinda lean towards nothing.

 

Hope that is true. Would be a real bummer to find out they didn't check or were wrong in assuming it was so

 

Careful folks. The mods (and most of us members) don’t have much tolerance for inflammatory BS. That’s what the rest of the internet is for.

 

Understood.

 

keep it civil folks or vacations will be granted
