gas quality in Petro-Cnada has been reduced

KK1

This evening, I went to Petro-Canada on Burrard St just south of 2nd Ave for gas as usual but pump octane 94 has been missed. I was quite confused so drove to another one on 4th Ave just east of Cypress St. It was still the same. Now, the best quality is octane 91 in Retro-Canada. Finally, I had to fueled up in Chevron with octane 94

I remember reading some online analysis about how Esso gas used to be one of the worst because of the higher sulphur content (sulphur is a leading cause of acid rain). It was within spec of what the government mandated, but it was quite a bit higher than many of the much cleaner competitors. I believe Esso has since reduced the sulphur content in its gasoline, but they are not in the Top Tier program, so for things that I don't know enough about, I prefer the standards guaranteed by some sort of certification program.

In the past, ethanol-blended gas from Husky/Mohawk gave me some slightly better tail pipe emissions at the expense of a minimal drop in fuel economy. My engine seems happiest (smoother, more powerful) with Chevron, and both Petro Canada and Husky gas seem to work quite well as well. SuperStore gasoline was definitely the worse as far as power is concerned, but the engine never exploded either.

Different engines could also be happier with different brands of gasoline (due to their additive packages). It is best to try a couple of tanks of the same gas from different retailers, and do some data logging to determine which brand seem to work best with your particular car.

Hm...I actually think Esso is not bad...on the few cars that I drove, Esso gave me the best mileage...power?  I don't know...I care more about gas mileage right now...LOL

I don't think Petro Canada gas is that bad. Esso is the worst (as I heard).
My friend who is super "care" of his car (porshe), do fill up petro canada gas (94).

few cents a litre means few dollars a tank....one tank per week/1.5week becomes 10 bucks a month....a year will be 120 dollars...thats a lot of money (you probably think that 120 bucks is nothing...but thats a lot to me already...)

Thanks Lik, I'd prefer using Chevron

How much is too much cash? Actually, the differences between octane 91 and 94 are only a few cents in price. I think everybody driving a car should be affordable to pay for…
There are people that have too much cash but not you, how can you lend a hand to take some, prostitutes?
