makes sense, google to the rescue

It does not matter whats at the bottom of a tank because the pump is set so when there is about 1000 liters left the gas will be below the pump and it will stop pumping. Also every gas dispenser has fuel filters like the ones you have in your car for oil to make sure the gas that goes in your car is clean. Having had a gas station for 26 plus years and 1000's of gas deliveries we have only had one gas mix up where the driver accidentally put premium in the regular tank. We knew about it the next morning when our monitoring system showed we where low on premium but the invoice showed we had it delivered and we had more regular than we ordered.

94 is a waste of money. If your car says use premium use 91.

So how often do gas station tanks get cleaned? Once a quarter? Once every 6 months? Once a year? Once in a blue moon?

I have never heard of tanks getting cleaned. Family has been selling gas for 26 years and we also know many gas station owners.

Doesn't ethanol wear your engine out faster?

The only ethanol-free gas I know of is Chevron 94 octane.

Only if you have a very old car ie 30+ years old. designed when ethanol in fuel was uncommon and are still using all OE plastic fuel lines.. even then it just wear faster, doesn't mean it melt right away.

it is just sign of the times.. with electrification coming..Bolt, Model 3, etc etc for most people fueling at a station would be in the past. Did we mourn when Blockbuster, Rogers etc got replaced with Netflix? or software aisles at Future Shop got replaced with Apple app store?

It takes a decade or so for the station to be remediated properly for the next purpose.. so it is a good time to start now.

so Shell 91 is next up under Chevron 94?

Next up for what?

Depends on company and what the inspection report states, usually it's around 10 years for smaller tanks (~8 feet in diameter), can go up to 30 years for larger ones (~120 foot diameter). That's for the actual terminals, individual gas stations have different standards.

And yes that's true, the gas stations do have filters and no the suction isn't sitting on the bottom of the tank, but when you fill a tank the settlement still gets disturbed. I'd rather drink a clean glass of water than drink out of a muddy puddle with a life straw. Yes both are safe, but I'll take the piece of mind anyday

For quality?

higher octane isn't "better" gas, look up the definition of what it actually means.

you only NEED 94 if your car is specifically tuned for it.

if you're not tuned, put in what your vehicle manufacturer tells you to put in and you'll be fine. putting 94 in a honda civic isn't gonna make it faster or last longer.

Then it settles. You will not get sand or any other contaminants in your tank.

It's all pretty much the same. No one gas is really superior.

If anybody is curious, a few RS members found interesting results between the different grades of fuels and brands.

It's an older thread, about 3 or 4 years old, but it's worth a read as it rebukes Manic's posts in this thread. As always, take this thread and the linked thread with a grain of salt.

Disclaimer: I am not calling Manic a liar or disagreeing with what he posted. Just wanted to offer a different opinion and take on the topic for others to read. Again, it is an old thread, and somewhat related.

I usually fill with Shell 91, but for my winter beater I've been going to the gas bar at Superstore instead and noticed that their 91 states that they have no ethanol. Anyone know where they source their gas from?

my Honda drinks that Kirkland Signature bulk fuel...probably just marketing

Unless you got yourself some JDM rides which were tuned aggressive as all hell.... running 91 vs 94 on any gen Impreza STI RHD and you can hear it knock itself to death. :yuno:

Gas in North America is designed for cars sold in North America. You can't expect them to make as for cars not originally sold here. 94 is pretty much only available in B.C. Most of Canada only has 91.

What about the GTR guys who made more power on the dyno 91 or 92 Chevron US vs 94 Chevron in Canada? Why do they get better fuel in states?

I got better mileage in my Prelude with Esso than with anything else, that may have been a fluke or just something to do with the local stations though. Shell I'll still never trust after that fiasco 20 years ago so Chevron is a must for my Celica GTFour.

How often do you clean the tank in your car?

Cuz they dont measure RON octane on the same scale you can thank imperial vs metric for that.

That has certainly not been my experience. When I was in Calgary for vacation last summer, every Petro Canada that I went to carried Ultra 94. Also in Ontario, from KW all the way through Toronto, many Sunoco and Chevron stations offer 94 octane gas as well. But I don't think the Petro Canadas in Montreal carry Ultra 94. At least, I haven't come across one.

So at least in Vancouver, Calgary, and GTA + a little beyond, 94 octane gas is quite readily available.

94 Octane from Chevron for the bike because no ethanol.
