It's $16 for absolutely zero benefit.

My car wants premium and I always get it better never really knew why. Nice to have an explanation in this thread. 90 octane minimum.

Has anyone heard the Husky ads on the radio lately claiming to be doing you a big favor by offering premium grade ethanol blended gas at the same price as regular? Cracks me up because the premium gas will result in lower mileage for most cars, and hence more fillups at Husky to get that "discount" premium gas...

In a gasoline engine I recommend adding fuel injector cleaner every month or two. Getting a fuel system flush every tune up also is a good idea. Especially if you buy your gas from an old or shaddy gas station.

In diesel engines I suggest adding a lubricity agent to your fuel at every fill up. I use dieselkleen by powerservice. Ultra low sulphur diesel is very poor a lubricating the injectors and its one of the most expensive repairs on those motors. You can also fill up with #2 diesel but its not usually available except at a few shell stations. Some diesel guys also add half a quart of ash free two stroke oil or seafoam to accomplish the same thing.

Husky gives you 90 octane for the same price as 87 octane at most other gas stations. Fill up at Husky!

I recommend this for a good read: http://en.wikipedia.org/wiki/Octane_rating

If you really want to flush/clean the fuel system or injectors, get a bottle of the cleaner fluid from Canuck Tire and put it in your empty tank before filling. Do this a couple times a year.

Bang on

DO what your manual says. Basically says to me, use 91 octane, but 87 will do in a pinch.

I've always questioned if it really was 90 octane. I fill up at Husky regularly, but I really don't believe it actually is 90. The difference between 90 and 92 is like 15 cents, and that seems a little off to me.

I haven't really questioned it. I usually go to Husky because it's convenient for me. There's one one block away from my place.

I guess I just find it hard to believe a gas station could afford to take a 10 cent hit on each litre it sells. I think there must be another reason Husky offers 90 octane or claims it's 90 octane.

Co-op sells their fuel for 8 cents lower than the posted price if you're a member. Their posted price for 87 octane is usually the same as everywhere else so I'm not sure how they take that hit either.

Yah but 4 cents is some sort of government tax write off and the other 4 cents you get in co-op credit.

Unless of course you do the opposite and run 87 ocatane when it calls for 91.

I get about 200km a tank with 87
and about 350 with 91


Simple answer, use the octane of fuel your car recomends, most people have mentioned this but your car will be mapped for the recomended octane

I find that the occasional tank of premium makes the car seem to run a little better, and I can measure the difference in gas mileage. Sure the gas milage advantage doesn't pay all of the extra cost for premium, but some of it.

So would 90 octane be considered premium? Or is that 91 and over?

Yep. Your car's ECU is compensating for the lower than recommended octane gas.

Then you may have an issue with your car which is actually making use of the higher octane. If your car requires 87, but you put in 91 and you improve performance and mileage, then there may be cause for concern because this shouldn't happen.

Other than that, it's a placebo effect or coincidence. 91 doesn't have more potential energy in it than 87 does.

It doesn't really matter what is deemed premium. Just go with what the car manufacturer recommends.

Mine recommends Premium gas....

[Super Nintendo Chalmers]

Hmm, usually they give an octane number.

It's because Husky = Mohawk and has the highest ratio of ethanol.

High ethanol blends are more corrosive and you will also get worse fuel economy off of this stuff than anything else.

Sadly, in Calgary, it's the only option to get 93+ octane from a pump for those with cars tuned for it. I wish we would get Chevron here.
