You can even mix your own. Use to use a 5 gallon gas can, put in a gallon of E85 then 4 of E20 and would have E35 to throw in my vehicle.
Most vehicles can handle E30 fine, and even higher. Never heard of the E30 challenge?
At the gas station. Ethonol blending pumps around here if you look. Although due to the rise of E25 E30 is now a scarce option. Usually it is E85, E30, and E15 offered. Although know of one place that offered E30, E29, and E25 next to the E85
You still have not said where you are that E20 is sold or what these vehicles are that you are putting this E20 and E30 in.
Not true, can damage elastomers and the engine control computers arenāt set up for such low-energy fuels. Did someone drive a car with E30 on a Youtube? Maybe, but I bet thereās no chance they did it for a while then checked for fuel system damage.
As for mixing it up at home, why do such a messy, dangerous thing? Just pump the amounts desired (even though that is also a bad idea).
Just make sure your vehicle is equipped (factory or aftermarket) with an ethanol blend sensor that measures the percentage of ethanol in a fuel mixture or your air/fuel ratios are gonna be offā¦
My 2023 Toyota clearly states on the gas cap and warnings in the owners manualādo NOT use E15, anything between E10 and E0 is OKā¦
Also the vehicles fuel system must be able to handle higher ethanol levels or damage can/will happenā¦
With a single hose serving several blends, I have been cautioned that about a half gallon remains in the hose from the last customer. Not a big deal except when I buy non oxy for the small engines. Suppose I could run a gallon in the car first but not surebitscworthnit.
Well, been using it for almost 10 years in my 2003 vehicle. The metal if the vehicle will rust away due to the salt they put on the roads here during the winter long before I have any fuel system issues. BTW, mid 90ās pretty much all vehicles were being made with ethanol resistant seals. And yes, many electronics in cars starting with obd2 will adjust quite a ways for higher ethanol.
You still have not told what this vehicle is or where you are located that you can buy E20.
Interesting, all of the E0 (90 octane only) pumps in my area have a separate pump off to the very edge of the property for filling up boats, lawn equipment etc etcā¦
Here is one example for maybe the only remaining PB station in my area (period) that still carries E0, I have gassed up my fun car many times thereā¦ But our E0 is also all 90 octane for the top tier stations so not in with the regular E10 fuelsā¦ So no mixing of fuels remaining in the pump hosesā¦
South Dakota. Local police and the police in the town 100 miles over I grew at at use E30 in their vehicles. Believe the highway patrol do also. Know they tested it at one time in their Dodge Chargers they had at the time. American car companies pretty much made theirfuel system parts ethanol tolerant in the mid 90s. Toyota is cheap on their parts so they probably didnāt update as early.
Use to mix a gallon of E85 with 4 gallons of E10 to get a 25 percent ethanol fuel. Would use a five gallon gas can then pour it into a 93 Cadillac Deville. Then a few blender pumps appeared at stations in town offering E20 and E30 next to the E85. This was back in 2008. Before my current vehicle I had a 1995 Bonneville that ran fine in E20. The town I grew in in people were putting E30 in their non flex fuel vehicles. Somehow it caught the eye of the EPS. And someone from the EPA was at a station telling people they couldnāt use E30 in their vehicles if they werenāt flex fuel vehicles. The people told him to F off. He tried everything to shut that station down. But in the end there was no law to enforce. That town has more stations with E30 option than where I live, despite being a slightly smaller community. The University of Nebraska did tests on non flex fuel vehicles. Determined that they all operated fine using E30 and didnāt harm anything on the vehicles. Was reading that someplace that was testing different ethanol blends on different vehicles went up to 60 percent ethanol on a Prius before it effected engine performance and throwing a lean code.
Btw, my current vehicle I use E30 in is a 2003 Chevy Tracker. Just a 4 cylinder 2 liter engine. From what I have read the 6 and 8 cylinder vehicles test the same fuel mileage on E30 as E10, the 4 cylinder engines did a bit better for fuel mileage going from E10 to E30.
At least three stations where I live with the E30 option. One has E85 with E30 and E15.
Another just has E85 with an E30 option. Before they redid the place and pumps they use to have E85, E59, E39, and E20.
The third has E85 with E39, E20, and E15 option.
A fourth place use to have E30 and E15, but they rebranded and donāt think they have the E30 anymore.

Our South Dakota farmer relatives make a lot of money selling corn to ethanol plants as well as investing in them. So there is a lot of public support of the product. The Mobil station I used for 40 years was bought out by the local co-op. Just noticed yesterday that their pumps now reflect 10%. In the back of my mind I was wondering if the gas was being watered down because it seemed like my usage was up in the last month or so. Maybe this is why. Not changing anything at this point. Still top tier and premium is still non-oxy for my small engines.
If itās Top Tier gas, and advertised as E10, it will have at most 10% ethanol. Top Tier monitors retailers to ensure that the gasoline they sell meets Top Tier standards. If a station adds ethanol to the storage tank, it will dilute the Top Tier additives. If there is enough ethanol added to notice a difference in gas mileage, then it seems likely that the gas they sell is no longer in the acceptable additive range. That would get them kicked off the Top Tier list, and if they are selling a national brand like Exxon, they might lose their affiliation with that brand. Not worth it IMO.
Petroleum companies blend E10 gasoline, not the gas stations. Where would a gas station clerk get ethanol from?
As for those late arriving E10 labels for the gas pumps:
As of January 2008, three states ā Missouri, Minnesota, and Hawaii ā require ethanol to be blended with gasoline motor fuel. Many cities also require ethanol blends due to non-attainment of federal air quality goals.
E10 has been the standard fuel used in the U.S. for more than a decade.
I tried a 30% ethanol mix in my last Mustang by putting E85 into my tank with premium. It ran great, but lost fuel economy. Long term fuel trims were still in range but you could clearly see they were high.
I wanted to test it as a track fuel blend but I could not find any stations near the race track selling E85.
@bing implied that the gasoline he sometimes used had more ethanol than E10, enough that he noticed a reduction in gas mileage. I agree with you that raw gasoline has all the additives, including ethanol, blended by the petroleum company. If ethanol is added, resulting in reduced mileage, it must be by the retailer. Again, that is highly unlikely as I said above.
I miss the old days, when gas was just GAS. Especially that relatively short period in time between when lead was outlawed, and before Ethanol became an additive. Late 1970s to early 2000s?
