Bad Gas

Got a hold of some the other day... It was from a place I rarely buy gas from, but I forgot to stop at my usual (for 100%) on my way home, and so filled the bike (carbureted) with 91 E10 at this alternate place, as a matter of convenience.

Well, long story short, I almost got stranded the next day on the way home, and after wondering if it was fuel selector or fuel pump, since it acted like fuel starvation (while thinking the different gas was an awfully suspicious coincidence), I drained it and it initially looked like cloudy lemonade.

I took a sample in a glass jar when I saw that. At first there was a layer near the bottom that looked like sugar, then cloudy above. The pic captures that if you look close. That eventually resolves into 2 distinct clear layers, but the bottom one does NOT look like water. The upper layer can be made cloudy again with just a little agitation.

I quickly got some good gas back into the bike, and ran it for 10min in the garage, test driving it the next day. It wasn't Ok for a bit (mid-range RPMs were spluttery), but it eventually cleared up (thankfully) after 6 or 8 tries of getting it to rev good. I don't know if there was residual bad stuff in the bowls or whatnot that just needed to be cleared out, or if some of the passages actually got clogged with some kind of precipitate, but were able to be flushed out with the clean stuff. I'm hoping no undetected damage was done to any O-rings, etc.

I stopped by the store I bought it from on the way home (from refilling it at the good place, lol), with the idea of at least coming back to show them the sample and get a refund, but also to you know, let them know they had an issue - at least on the day I bought - but the young lazy-voiced and -mannered manager couldn't have cared less, and refused any kind of refund (as a matter of policy on gas). I wasn't really prepared for that kind of a response; basically told me to get lost and don't come back (albeit in a calm way) after I argued the point a bit with her (which I should have just dropped, looking back on it). Anyway, I made an online complaint with the corporate brand after that, but don't know what'll come of that. I don't care if I get a refund or not, but I would like someone to say to me, "Yeah, that wasn't cool, and how can we prevent that, or find out what happened?" A little empathy.

Now I've got 5 gallons of cr@p gas that I don't know what to do with, lol. Idk if it's got diesel in it or what...

You can usually pour off the water and use the gasoline. Put a bit of 2 cycle oil in the mix to color the gasoline and ethyl alcohol, as the water will not change color.

In a 5 gallon Jerry can, you could dose it with an oz or 2 of the 2 cycle oil, stir a bit and wait for it to settle, and then siphon from the bottom of the gas can. When you see color, you have gotten the water out.

I have done this a few times and used it in the lawn mower that is not as temperamental. The crappy stuff I’ll pour into a shallow pan a bit at a time and let it evaporate in the sun.

My buddys girl did that to his 72 mustang.
Luckily she only put a few bucks worth in so he just filled it up and ran it through. It was a bit Smokey for awhile but all was well.

Mixing E0 and E10 is just asking for problems.

Moisture condensates and collects in the E0 tanks as well. Any residue water in the bottom of the tank from E0 would almost immediately separate when adding E10 into the mix.

If they have bad gas it’ll probably rear its ugly head to some other unsuspecting customers. It’s good you went back and complained and got on record with your complaint to corporate. There was a gas station on the news here not long ago that sold some bad gas. It was in a populated area and many cars were affected, cost them a lot of money.

Years back, I got some bad gas from a local popular fuel station. Same as you, did the glass container trick, took it to the station and they did nothing.
So I waited until 5 o'clock rush, went back and showed all the patrons waiting in line the bad fuel they were about to buy. About two dozen cars left, the manager came out and we put on a good show for all to see. Manager finally tossed a 25 dollar gift card at me and ask me to leave. Word spread quickly, it was quite some time before business picked up again....I have never been back!

A while ago a local garage ( they were arseholes but they were all there was ) any how one of the arseholes set the after hours fuel bowser to sell fuel at 14c per litre instead of $1.40.( yep , it was a while ago , 95 is now $2.70-ish ) The good news spread like wildfire and most who new filled everything they had with fuel . Well didnt it hit the fan next morn , the arsehole went ballistic calling everyone thieves and ranting on about tracing eftpos transactions . They spent about a week spewing at everyone . Banks wouldnt help ( privacy laws ? ) police didnt want to know because no crime was committed . In the end the were reduced to apologising and asking those who took advantage of their mistake to come and pay up .
Also local to me now , different end of the South Island , went to fill the lawn mower can , filled the can and went to pay and found the place was shut but someone had left the pumps on . It took me over an hour to find someone to turn them off before the township found out . I has to ring the franchisee fuel company who contacted the owners . Police didnt want to know . Difference was that they were nice peeps , lady cried when she realised I took only 5l of fuel and then hung round and got it sorted instead of filling my car and shooting thru .

I've learned some stuff over this. I had my sample tested (the state agency overseeing got right on it), and it turns out to be phase separation or some such - a likely ethanol-water mix in the bottom layer, from which it takes a good long while for the water to separate out of (I think the guy said a couple of weeks maybe).

So the next question is, did the water come from my tank or theirs? I use Reserve on every tank, and leave it there until I get home, as my normal habit after filling up (to "see if anything happens" with the new tank of gas while pulling from the lowest possible point). I've never gotten any kind of stuttering or whatnot using Reserve, which I'd think would happen if I had water; even if it was below the lowest port (part of the "unusable fuel" volume), since it sloshes around and so forth.

So if it WAS me, and the water has just stayed separated out of the 100% gas I normally use, I'm even more averse after this little fiasco, to anything with ethanol in it, and will be supporting the makers and sellers of 100% gas when I can. Regardless, whether it was them or me, the nice little "water blend" that resulted nearly got me stranded in a most unpleasant spot, and the gasoline that was left after the ethanol is pulled out is of a lower octane, which isn't good either in a high performance machine like this (obviously). And at best, even when it's not contaminated, it yields less mpg. What a great idea...

Odds are you got the bad gas from the station unless you let your vehicle set for long periods of time, ( a month or more)...Our area had fuel issues some years back due to lack if maintenance at the local stations. The locals started a co open fuel center where tanks, filters and everything us properly maintained. Never have we had a problem with E fuels since. Anything stored for 30 days or longer gets fuel stabilizer.

I have used it very regularly. It hasn't sat long at all unless it's been down for some kind of maintenance, which has been a while.

I ride it so much it's my 4-wheelers that I have to start/drive once in a while just because, to keep exercised, lol. Coming up on winter though, so...

I've told the story before, but I sold my previous one to get my boat in 2018. Didn't really plan to have one again until my son got one and got me back into it. That was 3 years ago. I have used it SO much more than the boat, mainly commuting.
