Thankfully butane and propane are completely mix-able. We frequently used to either blend on board C3/C4 for discharge at ports that were unable to take the fully refrigerated C3 at -43 deg C. The vapour pressure, density and boiling point of the mix is a very simple straight ratio between the twoI always fill before going them I know I have 100% propane on board. I try not to come back with too much if I'm going to use the van in the winter in the UK.
I think France can be up to 45% butane and Spain is up to 65%, percentage varies on time of year and how far south.
Just bought the bag of all 3Don't forget to take an adaptor too.
& for petrol & diesel! Haven't seen that anywhere except on toll roads before last week.Don't forget many French fillings stations with you to pay before you fill with lpg.
That's good to know, I had wondered if they separated out in the tank.Thankfully butane and propane are completely mix-able.

There seems to be many more gas driven cars in France than here.Slightly related to the thread, I found on my last trip to France that both fuel stations I filled up at had a notice stating that the gas was only for propelling the vehicle and not for filling of domestic tanks. I don't know how this is going to affect us in the future?
Total station by any chance, they banned filling hab tanks a few years ago.Slightly related to the thread, I found on my last trip to France that both fuel stations I filled up at had a notice stating that the gas was only for propelling the vehicle and not for filling of domestic tanks.

But the high butane content causes gassing of problems in low temperatures also Truma Combi's often fall over on high butane content as butane can not supply the high flow rate required.Thankfully butane and propane are completely mix-able.

That is correct for pure n-butane which boils at approx -2 deg c.( IsoButane boils at -10 deg c) - however a mix of butane and propane will boil at the temperature proportional to the ratio, due to the intermolecular bonds being also the same on each.But the high butane content causes gassing of problems in low temperatures also Truma Combi's often fall over on high butane content as butane can not supply the high flow rate required.
Not a problem for LPG fueled engines as they use a liquid take off.
Have a read of the above post if you are really boredThat's good to know, I had wondered if they separated out in the tank.

Most UK supermarkets are taking £100 if using pay at the pump. Balance (if any) returned.& for petrol & diesel! Haven't seen that anywhere except on toll roads before last week.
Filled in Arras and that was pay before you fill , no specific amount but was asked how much i would be putting in and it took a deposit off the card then refunded on fill up.Most UK supermarkets are taking £100 if using pay at the pump. Balance (if any) returned.
