My 20L Jerry can has started holding only 17L
Discussion
It's possible that I am losing my mind but...
I have an old WW2 jerry can that originally belonged to my grandfather. I use it to get fuel into my race car and have done for the past 3 or 4 years. Previously it would happily hold ~20L (a little more if I brimmed it but you get the idea).
I've used it twice in the past week at an Esso petrol station on the A40 (different pumps each time) and both times it has held only 17L.
This matters because the fuel gauge on my race car doesn't really work and so I work out amounts based on fuel burn.
So, have I happened upon the only generous fuel station in the world and I actually have 20L or is there something else going on which I am missing (temperature, expansion etc etc). It's not a huge problem, I just don't want to embarrass myself by running out of fuel on track!

Maybe in the past you have been paying for 20 but only getting 17.I have an old WW2 jerry can that originally belonged to my grandfather.

Happens to steel fuel containers where they contract over winter which distorts them permanently, reducing capacity. I have one that did it. You should be able to see the thing has gone concave in shape on the sides.I have an old WW2 jerry can that originally belonged to my grandfather.

Interesting! That may be what has happened. It's been empty in my garage all winter.Gassing Station | Home Mechanics | Top of Page | What's New | My Stuff
