Wow, thanks for the tip, there IS a Flying J in Montreal... Yeah!!! I'm going to tank up this weekened when I go there... I paid 15 cents more a couple of days ago (1.599 two days ago)
And, as expected, we pay the HIGHEST for Diesel in La Belle Province... Je m'en Souviendrai!!!
If you pay cash you get another 3 cents/l off (see note at bottom of Flying J page). Of course at a card lock only site you can't pay cash. The usual procedure is you go into the cardlock store say and say you want a fill. I usually leave the credit card as collateral otherwise it is pre-pay. They will set you up on a pump. Once you are set-up on a pump with a credit card, you can use that pump any time. Depending on the system, you may have access to other pumps on that card reader. The easiest way is to get a cardlock card. Be careful as the high flow pumps are just that and not designed to be used on personal vehicle tanks. If you are not careful you will be getting a diesel bath. The station I have used also has a "trickle pump" which is fine for small jerry cans but too slow for a 95L tank.
