How long does a propane tank on a gas grill usually last?

  • c

I know I should get a second tank, but generally how long does a tank last? I cook on it 2 or 3 times a week for about 45 minutes a shot. I've had it for 3 weeks. Thanks.

  1. There's really a lot of variables, including the flow rate, the BTU output of the burners, and how high you run the burners. Sorry I can't be more help, but it sounds like you're possibly almost out, maybe a couple of weeks left if you're lucky.

      It lasts until you have about ten hungry people standing around with plates in their hands. You hear a little *poof* and it's lights out. Keep an extra tank on hand.

          Thanks for the tips! I made it through my cookout last night without any problems. But I think I'll pick up an extra tank today. Hey, I'm new at th is homeowner/grill for the neighborhood kind of stuff! Thanks again.

      1. To figure out how much you have left, take a cup of boiling water and slowly pour it down the side of the tank. Wait a few seconds, then feel along the side of the tank. You'll find a spot where the metal goes from hot to cold. That indicates the level of the remaining fuel.

        By the way, I always keep one or two of those one-shot Coleman cannisters around. So if the main tank runs out, you can at least finish up what you're doing.

          The Coleman cannisters are a great idea. I'm wondering how much they cost.

          I go so far as to keep a second propane tank at the ready. If you use your grill often, it's pretty easy to justify the modest additional expense.

          There's nothing like the peace of mind knowing that when you have 8 guests over and a $60 beef tenderloin on the spit that you're not going to run out of gas half way through.

            Yep, I do the same thing. You never have any worries. Why *wouldn't* you have a spare? I bought a 2nd tank right after I got my first gas grill.

          1. My Weber has a gauge on the clamp that holds the tank that shows relative fullness.
            I would typically get 6-7 weeks out of a tank, using an average of twice per week for 30-40 minutes.
