Except...

You still have petrol (I would image less than 5% if installs remove the tank and have a split lpg/petrol tank) so your point makes no sense what so ever in those situations.

For the 95% covered the lpg tank goes in the spare whee well (crumple zone), boot (crumple zone) or under the side of the car (maybe not crumple zone but 4 inches from edge).

So no, clearly its not safer is it?

In a car accident it has been proved (Holland independent test TNO) lpg car are safer than petrol cars.
The tank makes the structure more resistant not the other way round.
Also the tank has at least 3 safety valves.
There is nothing to discuss about safety.

Right,

So my petrol car for example with 60l of petrol remains equipped with 60l of petrol AND 40l of lpg.

Somehow taking the same vehicle with the same amount of petrol its safer when you add lpg?


I am sure you can understand my confusion.

I'm just going to join the safety debate as it's a popular "discussion" with my dad....

The LPG tanks are very strong pressure vessels so are significantly less likely to rupture in a crash than a plastic petrol tank.

However if there was to be a major leak, LPG will immediately vaporise and disperse, unlike petrol which will spill and linger. But you do not want to be within a hundred yards of it if it does burst or snap a connector off.... however unlikely that might be.

So whilst logic says a car in a crash carrying 60L of petrol and 30L of LPG is going to be less safe than just 60L of petrol, but I think the probability of there being an issue like that is very low.

Interesting watch :

Or buy a diesel which will not readily combust in an accident, offers similar mpg, is available at all service stations and works.

And makes lots of noise, clogs a DPF if used on short runs, pumps out black soot and has a lot of harmful small particles coming out of the exhaust.

Thats a real I'm fine thanks and two fingers up to the next generation attitude

Back to the fire aspect a VW I converted many years ago. A year or so I had a phone call from the owner saying the camper had caught fire. A petrol hose had started leaking causing it to catch on fire while parked. The LPG tank survived intact and the fire brigade who attended were impressed at how safely the LPG side burned. The LPG tank was still intact while the rest of the van had disapeared. The reason for the call is they had now purchased a replacement and wanted that converting. Also while we were there adding a fire exitnguisher system aimed mainly at all the petrol components just in case the same kind of thing should ever happen again. The safest thing would be to remove all the petrol system and run LPG only but regulary checked and any suspect items replaced at the first sign of problems petrol can be a fairly safe fuel. Whatever fuel you use there is always a risk
