No Ethanol vs Ethanol gas

[ht_addict]

Title pretty much says it all. Local CT sells Premium 91 with No Ethanol, everyone else has Premium 91 with upto 10% Ethanol. Price is pretty much the same give our take a few pennies. Which way would you go

The Stinger won't care, your lawnmower might.

Ethanol has higher octane but lower energy density than gasoline, so you might get slightly better fuel economy with the no-E fuel (ethanol gas is usually cheaper, so whether the price breaks even I can't say). There will be no performance difference.

Use non-ethanol in anything that has rubber fuel plumbing or gaskets more than 20 years old (or a carb that hasn't been rebuilt in the past 20 years). Also useful for anything that will sit for months at a time.
Just throw some stabilizer in ethanol fuel in anything that will sit for more than 3 months and/or drain the fuel.

Otherwise, no big deal for anything modern.

CT as in Canadian Tire? Shell, Costco, and one other brand (that I don't remember) has zero ethanol in their premium fuel as well

This right here. It truly is that simple.

 

[EClapp3]

Yeah, like others said the ethanol content wont hurt anything halfway modern now.

If it is nearly the same price, I would go for the non-ethanol gas.

Non-ethanol, assuming they are both honest at 91, will give you better mpg/mileage/ L-100km, whatever your measure is.

Gasoline has more energy per volume than ethanol. If they are mixing in 10% ethanol, you're losing like 20-25% of 10%, or maybe 2-3% overall mpg, if it matters to you. Could be the difference between 30 and 31 mpg, just roughly.

Plus, if you're planning on mixing E85 to raise octane, you can get to a higher total octane if you start with pure gas than E10. E10 likely means they started with like 89-octane and boosted it 2 points (not sure if that's the right word, I've seen points mean 0.1 instead 1.0 for octane) already using the E85. You will have a slightly lower injector duty cycle with G91 than E10, so you can flow more overall fuel, if you're into tuning, as well.

All things being equal, choose pure gasoline over E10.

I mix ~E30, because I can only get 91 octane from the pump (E10, I believe). If I could buy straight G93 at less than $6-7/gallon, I would.

I experimented with this just last week; pumped 6 gallons of non-ethanol 92, which turned out to be $1.20 MORE per gallon than 93 octane. It was awful and I definitely won't be trying that again. The engine really seemed to struggle, whereas on 93 acceleration is always effortless.

Gas mileage seemed a tad better, but personally, it's just not worth it, since performance took a hit.

Just run some 91% isopropyl alcohol from the shelf at Walmart

As an FYi, my understanding is that not all Petro Canada gas stations have ethanol in their premium gas. Those that were Sunoco stations (with 94) have ethanol blended grades. Those that were originally Petro Canada stations do not have ethanol blends. This is because the gas comes from different refineries.

 

[ht_addict]

Damn goverment regulations. Now CT has Ethanol in all blends.

Ethanol gas notoriously goes sour much faster than non-ethanol. I only use non-ethanol gas in my 5000 mile 2009 G8 GT garage queen, and my seldom-used outboard boat. For two-cycle yard equipment nothing is cheaper than $25/gallon Trufuel.

….. Which way would you go

Well, how did it go? Assuming you had to find out for yourself. I’m curious what your experience was.

I have gt-line with 1.6TGDI and find 0ETH to be more responsive and snappy on the peddle.

If the prices are similar, and this is your daily driver, either is fine. Its more important to get your fuel at a busy gas station. This is especially true for premium gas, which doesn't get pumped as much as regular gas. Fresh fuel is always better, especially if it has any ethanol, which is hydroscopic and will absorb moisture from the air over time.

Old gas is like free water injection!

The local costco here gets at least 3 deliveries per day. Whether those 3 include premium is uncertain, but definitely busy.

One here is too busy. I would gas up there, if there aren't always 3 cars lining up at every pump.

Last time I looked up regular vs. Premium sold, it's like around 88% vs. 11%. That ratio might be even higher at price conscious vendors like Costco.

I live in crook (cook) co. There's another costco in lake co. Generally prices in lake county are cheaper overall than cook (crook) including taxes. Over the last few months, comparing fuel prices between these 2 stations has indicated an anomaly. Specifically, lake co is more expensive than crook (cook) for premium. In fact, i track the page daily. Niles just jacked it up by 10¢ as of yesterday (friday). Come tuesday, it will drop 10¢.
