Best gas station for 87 octane: Shell or Esso

Topic starter

So ive narrowed down in Canada the best gas stations are Esso and Shell.

For my car i use 87, and in the video i linked it says Esso puts 20mg detergent per 100ml and Shell puts 16mg.

but for 93 Esso puts 21mg while Shell uses 31mg.

So basically if Im only using 87 use Esso>Shell? or does shell better additives as well?

 

Also does it matter if i top off my tank in the winter? Thanks

All gas is good these days... in 1st world countries anyway.  And imo, always better to have a full tank than not, less potential for condensate and your always ready to GO!

Arguably gas with techron is the best... what I use but really wouldn't be noticeable in most cars today in real world.

eome gas pumps are called toptier gas and apparently some car manufacturers recommend those:

They add some additives that could potentially help cleaning the engine and run better, although the base ingredients of gas is the same for all the gas stations.

Don't buy the hype. I don't look for particular gas stations. Just fill up where convenient.


might aswell use the best its theyre all the same price but thanks


show me experimental evidence where 20mg of some crap made an engine last longer than 10mg. And there's so many flaws in the testing they show in the video. It smells a lot like bullplop to me. I would rather have more gas in my gas. If you do maintenance, then your engine won't die from being "too dirty".


got none lol its not my field of work.


rhetorical question. It's not my field either. I think we should be skeptical when the local news tries to oversimplify complex issues like this.

What ingredients do car makers suggest?  All I've see recommended is the octane.  Otherwise no recommendations.


The ingredients are trade secrets. So no one knows. The important thing is that most gas stations sell top tier gas. No need to put in additives in your tanks.


I guess I wasn't clear. If car makers do not recommend additives then why worry about them at all? Could additives be BS and not needed for most buyers?


I believe fuel standards are regulated by the government. Auto makers can make suggestions, but they generally have to work around what fuel producers put out there.


"Top Tier" is with "cleaners" to help the motor. Can't a Italian Tune-up do the same thing? The high RPM, high temp, fast fuel flow, could do as good, couldn't it?

Little old ladies that only drove to church and the supermarket had cars fall apart for many reasons but not motors.

I had a Uncle Carl that would buy new Oldsmobile cars every year. He had a high paying government job and could afford it, so he did. Anyway, Uncle Carl would take his brand new olds and burn rubber off the dealer's lot. Back then everyone said to do a "break-in" period. He said driving slow was just to save manufacturers warranty time.


yes the old italian tune up is great for burning carbon off the pistons, cat con, exhaust valves. It won't do jack for for the injectors. Not everyone has the opportunity or confidence to do that on the regular.

There is a break in period. Uncle Carl just likes to drive fast.


i found a list of auto makers that do recommend Top-Tier fuel. Ford was one of them but I have never seen it or heard anyone make issue over it. Also, "if" drivers were to be refused warranty coverage because of using non-recommended fuel there would be news somewhere about top-tier fuel. That makes me think additives to gas are personal choices and not worthy of double thoughts.


I think so too.
