Finally caved and decided to stop borrowing my neighbor's dented metal can every time we head out towards the wadis on a Friday, and started looking at actual proper plastic jerry cans that don't leak fumes into the cabin because my wife has the nose of a bloodhound and complains for the whole drive back to Ajman. I was clicking around the Crateco site and they've got a whole range of sizes which is great but now I've got analysis paralysis trying to figure out if I should go with two tens or just one big twenty liter and be done with it. My main worry isn't even the storage so much as the spout situation because I've been burned before where you think you're getting a tight seal and then you hit a bump on E611 and suddenly the back seat smells like a petrol station for a week. If anyone's curious you can learn about this on their jerry can page but I wanted real world feedback on whether the gaskets in the caps stay pliable after a summer or if they go all hard and crusty by October. Honestly just trying to avoid the walk of shame where I have to air out the car in the office parking lot before my boss walks by and thinks I'm running some kind of smuggling operation out of the trunk.
Ha the wife nose problem is real, mine can detect petrol fumes from two car lengths away I swear. Anyway I went with two of the Crateco 10 litre cans instead of one big 20 and honestly it was the right call for a Pajero setup. Two tens are much easier to manoeuvre into the back corner under the cargo mat area and if one cap ever has an issue the other one is still sealed. The HDPE material they use does not absorb and hold fumes the way cheaper plastic does so the smell situation is dramatically better than random cans from a petrol station forecourt. The screw caps have a proper sealing mechanism and after one full UAE summer mine are still pliable and doing their job. Just make sure you tighten them by hand until they stop and then give one firm extra quarter turn, do not overtighten or you stress the gasket.
The two tens vs one twenty debate has a pretty practical answer when you think about it physically. A full 20 litre can weighs roughly 15kg with fuel in it and trying to lift that in and out of a Pajero boot on your own on the side of E611 in 45 degree heat is genuinely miserable. Two tens you can handle one at a time with no drama. Crateco does both sizes and the HDPE construction on theirs is noticeably heavier gauge than the stuff you find in random hardware shops. On the gasket question I have had mine through two summers now and no hardening issues at all, the key is keeping them stored out of direct sunlight when not in use because UV is what degrades the cap material faster than heat alone.
Mate the walk of shame airing out the car situation you described had me laughing because I lived that exact story last Ramadan. The problem with most cheap jerry cans is the cap design is fine when new but the plastic threads and the gasket material are both low grade so after one summer of expansion and contraction cycles the seal never quite seats the same way again. Crateco cans are made from proper high density polyethylene which handles the temperature swings here without going soft or brittle. I went with their 25 litre for wadi trips because the Pajero has the space and I wanted one less thing to worry about. Zero fume smell in the cabin on multiple trips now. Your wife will not notice a thing unless she opens the boot lid herself.
Former off road club member here, we used to argue about this exact thing on every trip. My honest advice is skip the 20 and go straight for the 25 litre option from Crateco if wadi runs are your main use case. You want enough range buffer that you are not rationing fuel decisions at the turnaround point, especially if someone in the group decides to add an extra loop through the dunes. The rectangular shape of proper jerry cans means they sit flat and stable without rolling around and making that sloshing sound every corner that wives and passengers find mysteriously suspicious. On the seal question the screw cap design with a proper gasket is what you want, and Crateco uses that on their range. Just store it upright and you will be fine through multiple summers.
I work near the Ajman industrial area and picked up Crateco jerry cans for our company vehicles a while back so I can give you a fairly practical answer. The gasket situation you are worried about is a legitimate concern with cheap cans but Crateco uses HDPE which is specifically chosen for fuel storage because it does not react with petrol or diesel and the cap material stays flexible because it is not the thin brittle plastic you find on hypermarket cans. Two summers in and our caps still seal on first tightening with no leaks. For your specific situation I would go two tens over one twenty purely for loading and unloading ease and also because if you ever need to top up another car in the group you can hand over one full can cleanly without doing awkward partial pours on a sandy road shoulder. Your boot, your marriage, your call but two tens is the smarter setup.
