Hi all. Just chasing comments from people who use the black plastic 20L jerries. Have used them for petrol in the past and they seem to expand quite a bit when hot. I'm wanting to use them for diesel on the roof rack. Anyone had any bad experiences ?

Used them for years, petrol and diesel, no problems. Yes they do expand (more so with petrol) but you can avoid this by not filling them too much.

If packing on a roofrack I would suggest some padding to avoid wear due to rubbing on metal.

Tony Y,
I use mine for diesel, I found the opposite with the filling of the jerries, I found that the more vapour space in the jerry the worse the vapour / expanding issue, this may be to do with the lower flash point / vapour pressure of petrol versus diesel. Not sure of the explanation. Keep the shiny side up

Hi rads

I have been using one for a long time as well. I only use mine for diesel and have no problems what so ever. I usually carry mine in the back, not outside the vehicle.

Same here - used them for a while now, no problems.
As\said above, don't overfill them, leave a bit of expansion room.

Hi there Rads,
I have six of those black 20L Rheem jerries, i actually have them inside my offroad box trailer, no leaking probs with diesel. My only complaint is that the screw capped openings (the later model has 2 identical Filling/ pouring openings) are too small to handle the HI-FLOW bowser handpiece, you need to dribble it in. These HI-FLOW nozzles are a many out west for truck filling. The orange coloured ones seem to be the go, they have a huge opening and screwcap, but dont really look sturdy enough, maybe its a perception rather than a reality. Regards Michael.

Rads, It just occured to me if you have been using them for unleaded petrol you would not have had a problem filling them as the unleaded has a small nozzle, it would only be HI-FLOW Diesel and Leaded or the new LRP petrol that has the big nozzle and thus the problem. Michael

I've carried three of the black Rheem ones during several trips in very hot conditions. Stored on roof rack and containing petrol.

You're right, they do look more like a football under these conditions, but can say that I've never had a problem with them and they would have travelled on the roof for well over 50,000kms.

Incidentally, I pop riveted an aluminium "deck" on the roof rack so the containers sat on a flat surface rather than on the bars. Used one of those ratchet tie-downs to hold them in place. Bonus is that the aluminium deck on the roof rack keeps the vehicle cool as well.

No problems with diesel or petrol over many years. I've found if you fill'em up and don't leave an air space the expansion with heat is less of a problem. My explanation for that is that its the gas above the liquid that expands when its hot, the liquid itself doesn't expand (although the vapour pressure of petrol especially would increase a bit as the temp of the liquid increased). So if you reduce the gas space, there is less expansion, and less chance of rupture. Maybe a clever person could clarify this for us.

I can see the thread has cooled down but I've been in town and thought you should consider both steel and plastic, I've seen plastic easily cut and metal rubbed or peirced thru. If you are doing any remote stuff always carry a mix, yes black does seem to expend more. Also anything on the roof is like the mast on a boat it travels further and faster as the pendulum swings. And any weight helps it swing more.

Have been using the black jerrys, both 10 & 20 L, for nearly 10 years now, and have had no problems. The spouts tend to disappear/get lost, while mustering, but we use them mainly for refuelling motorbikes. It would need a LOT of severe use to damage them. Hooroo...

Severe use or accidents. I dropped a steel jerry on to rocks and it was peirced, out of interest mate dropped his plastic one same height, rocks and all and it bounced, no probs. Different trip, vehicle we were in convoy with hadn't secured a spade and it nicked a plastic jerry. I've also seen a steel one rubbed thru on a ratchet tie down.
1st rule s%*t happens.
