LPG VS Petrol: Which is Safer? | Fifth Gear 

Could never understand why we weren't encouraged to use lpg instead EVs, infrastructure was in place no need digging up streets for chargers and still cleaner

2020's in Eastern Europe, LPG still rules

Here in Australia we have heaps of Duel fuel (petrol and LPG system) cars & utes in the 25 years I've been here I've heard of one LPG car fire he had adjusted the system to run rich, buggered it up and 💥 but never heard of a tank exploding in a crash but have seen petrol systems go up in crashes, I know percentages count but if they were dangerous the skippies wouldn't use them.

In Holland, LPG is less than half the price of petrol. Road tax is a little bit higher, but at 12000 km's a year and more, LPG is cheaper than petrol. And yet so few people use it.

He says "Every LPG tank is made from 10mm thick steel"! No they're not. Autogas tank wall thickness is 2.5 to 4mm depending on design factors. A 10mm thick tank would be very heavy in a car.

LPG did suffer the same problem electric cars are suffering now: distribution network and refilling.

The government needs to offer more incentives for LPG refueling stations. I run my 01 Range Rover 4.0HSE on LPG 99% of the time without issue.

Its really cool seeing the same Cedric Taxi 8 years later on Jonny's channel (The Late Brake Show) posted the same day

Main problem with LPG is the massive lack of refill stations.

You are absolutely right in your LPG report from the UK. We did the same explosion tests here at Transport Canada labs in the 1980s. Collisions and the possible explosions showed that propane is a much safer fuel in transportation. Today however, those driving on internal combustion engines who do not want or have electric cars, as an alternative, should look into this LPG autogas option.

The single walled steel tanks are not used here due to the rupture hazard. Seems to be mostly during filling somehow? At least they have to be certified here, explaining why there are so few accidents.

Such a shame LPG and other natural gas vehicles never caught on in the USA. Yeah we had some buses or the Honda civic GX but that was about it during the Great Recession when gas prices were up. I work as a door dash driver and I’d love an LPG or CNG car but they never caught on here

Just converted my W212 e300 to LPG, With a full tank, costing about $40, i can ride on average 550 km, combined city/hwy. While with $40 of gasoline I cannot get any farther than 300km. And there isn't any change in my car's performace. They installed a button on my dashboard, so I can switch between LPG and gasoline with a press of the button. Very satisfyed with the result, the investment of conversion is worth every penny

LPG is very boost friendly too. I had a ride in a turbo V8 LPG Mustang in the late 80s. Hauled arse!

My parents run LPG in there Land Rover Discovery 3 4.4 v8 and it’s almost half the price of petrol and at its MOT the emissions are the best the garage say they’ve ever seen

This actually changed my mind about LPG

In Thailand, LPG is 3 times cheaper than Benzin95. Almost all of taxis and tuktuk have used LPG here for more than 60 years, maybe more. It is wildly used before I was born.

Interesting time to post this as LPG is as good as dead as a car fuel in the UK :) was that Jonnys taxi or did he get one after this video?

It's true petrol is dangerous just imagine replacing petrol in petrol stations with only LPG and diesel

LPG in Italy is the cheapest fuel... Normally Between 0,50 and 0,60€/L ... Then comes CNG with 0,90€/Kg, Third place Diesel between 1,3 and 1,4€/L and finally Petrol with a price between 1,5 and 1,6€/L

If it’s all so good, there must be a reason why it’s not used much, I’m guessing either it might not run for as long as petrol does (say 300k mile + cars) or governments make more money from petrol

It's funny that all those years later, Jonny actually (recently) bought a Nissan Cedric LPG taxi!

Gas is okay. Apart from hard starting and the occasional backfire, also you use more of it. It does burn cleaner but also drier i was only a kid when i was around a few lpg cars but i only remember seeing one with a valve saver kit that sucked upper cylinder lube in the intake. Torque is good to but generally the converters run outta steam fairly quickly.. we had an ex taxi that had 750000km on it still ran great never seen a valve saver kit in that car.

Thats why forklifts use gas and have bottles on the back for indoor use and diesel forklifts are more for outdoor use

LPG has been a great alternative, especially for turbocharging a factory engine. With lpg liking higher compression because of its higher octane, turbocharging a 9.0:1 engine and adding gas is a great combination.

lpg ask dacia about it, you can buy a brand new dacia equipped whit a petrol and lpg tank factory installed at no extra cost.

I run my 79 Caddy 7.5 ltr V8 on LPG and it runs great and no different than petrol but it's like doubling the MPG .

And that's why there are only 2,395 Vauxhall Omegas left in the UK (August 2021).

I think the question would be: are lpg valves more or less likely to be faulty than gas systems or are they easily safe?

Big tank in boot used to freak me out 💥

LOL what? Unlike LPG, petrol takes a lot of effort for the vapor concentration to become explosive, and you will clearly smell it way before it happens. Also no way a cigarette may ever set petrol on fire (also any gas btw), as the temperature is way too low.

Poor Omega

In the Netherlands the situation is slightly different, but no all that much. The government used to have tax benefits and even grants for conversion to LPG, but for some reason they stopped. The taxing is also different, as we pay more tax for LPG than for Petrol. And there is a difference between a bog standard LPG installation, and a G3 one. The G3 pay less tax, and are really the only viable option these days. But why is the tax higher anyway? If the government wants us to be better for the environment, surely they would make it cheaper from the start? Well, now...here comes the problem. If you pay less tax, they have less money to spend....and that should be avoided at all costs... Same is going to happen with Electric Battery cars, soon they will find a way to tax the electicity and any cost advantage will be gone. So....the only reason to buy an LPG car in the Netherlands is to make yourself feel good about being good to the environment.....and as it turns out, not many people are willen to take the inconveniance for that. (The tank does take up quite a bit of space, and you have to find filling stations that sell it)

Jonnys own TAXI now

I have an lpg car and well ive never blowed up soo

The reason why petrol explosion was more violent than LPG is because explosions are caused by gases expansion. In LPG case, the car is filled with a flammable gas, that ignites. However, in case of petrol there's also air, which expands after the petrol is ignited

Having owned a number of LPG Cars and Trucks theres a few more things worth noting. LPG is heavier than air so if you do have a leak it will sink to the lowest point which can be the drainage system. LPG is hard on ignition systems, it is much harder to ignite in an engine and it eats spark plugs at twice the rate of Petrol and you need 8mm plug leads and a remapped distributor or altered advance curve, ignore the maintainence and it will backfire through the intake violently and destroy stuff. LPG component maintainence is also important because the use of LPG leaves a tar like substance in the components over time. LPG in Aus is now 0.79 to 0.90 cents per litre in Australia where fuel is currently $1.55 ish and you generally use more litres LPG per km than Petrol. Ford AUstralia was the only company to ever create a dedicated LPG system and it worked really well and brought us the Green top Barra 6 cyl engine with heavier internals on the rotating mass because of the issue with backfiring if you didnt change your spark plugs every 15 to 20 thousand km. Finally I dont have LPG on any of my cars anymore.

In Turkey, lpg is waaay more popular due to stupidly high petrol prices. Some 3rd world country problems 🤦‍♂️

How can i start lpg business in uk

WRONG ! The problem with LPG is not that your car will blow up it's that your whole neighborhood could blow up! LPG is heavier than air so it will find all the lowest places and pool there until something ignites it. Leaking LPG tanks have been known to take out entire caravan parks and buildings and entire blocks .Having a Professionally fitted systems is no guarantee that a failure won't happen but fortunately it's fairly rare much rarer than an EV fire.

here in Australia we made factory made lpg cars, ive had one since 2009, only runs on lpg, fantastic much cleaner fuel, engine internals are spotless, oil never goes black, But we also are losing the industry here, seems silly as we have some of the worlds biggest natural lpg reserves, We sell it to places like japan ,where they pay for our lpg cheaper than us aussies pay for it , go figure,

Wow, so this is where Jonny first meets the Jonnycab, and fall in love nstantly! Historic moment.

in UK to tax a LPG car is only £10 cheaper than petrol car, + lpg is cheaper than petrol

Sad that LPG never got the recognition it deserved.

Gas is always more dangerous than gasoline, like a leakage in an accident. The leakage can be anywhere, even if the tank itself is sturdy. Liquids are much safer and easier to control with no or very low pressures.

Soo much better for environment

If new cars come from the factory it won't cost no more

Upon reflection the channel name fifth gear was a little short sighted.

What about CNG ?

5:21 Why they use propane not LPG mixture? Propane is diffrent than LPG

how is engine power affected?

LPG was a flop. I was only a little kid when it came about, but I do remember bits of it. One quite appealing proposition I've encountered is hydrogen. It's derived from water in a process called electrolysis, which involves adding sodium to water and then electrifying it. Existing petrol engines need very little work to convert them to run on it, so no new technology really needs to be implemented. Seeing how the only exhaust gases you'll get are water vapours, the fact that we're not exploring it is truly nonsensical. Especially over here in Britain, which is bloody notorious for large amounts of rainfall. Water really does fall from the sky, so finding water for it ain't a problem.

The real question is can you convert a plug-in hybrid to LPG to get the ultimate cheap to drive car?

I don't know why the government does not mandate new cars to run LPG

South KOREA LPG car good. My car fuel LPG . Very nice . KIA Cadenza (K7) V6 3.0 235 Hp 28kg.💪🏻 Lpi fuel injection system Hyundai Kia technologe very good.

lpg has 104 octane number(RON)

Love the way in Japan yen is like a massive figure compared to like pounds or euros

ขอรับการยืนยันหรืออ้างอิง:

different is LPG tanks into car trunk and can leak into interior. petrol not leak to interior always isolates

Does LPG burns faster then petrol?

haaaa ..wszysko nie prawda lpg jest bezpieczniejszy niz zbiornik benzyny

Rigged, biased test: Gasoline would fill up the cab, like LP can. It will drip onto the ground & not cause a fire or explosion in the vehicle cab section. I presume the staged test, the cab was sprayed with a significant amount of gasoline. LP. on the other hand when it leaks its forms a volitile gas which can fill into the cab of the vehicle.

Petrol car explode 1000 times more rate than lpg. Maybe becos more people use petrol

Everybody scared gas bottle...

Ahh yes i drive a diesel mate no problem for me ;)

@M.I.T

I hear that it also causes more wear on the engine due to lacking the lubricating properties of gasoline. Is this true?

Diesel 😉

I absolutely love those Japanese taxis!

Have had used LPG vehicles in Australia since it came out the very old systems did burn out valves and the seats once you had them modified with hardened no problems at all the new systems of today are far safer better management systems being all new vehicles now run on unleaded fuel they have already change the valves and seats so you don't have that problem. We had in Australia 5 auto manufactures now none, FORD Australia had a 6 cylinder engine made to run LPG then GMH eventually caught on far to late the TAXI"s in Australia where all LPG most where the FORD Falcon with a 6 cylinder Barra motor that since stopped manufacturing them when any FORD Faclon is wrecked the motor removed packed into containers shipped overseas a joke. I cannot understand why the huge push for EV's being the huge cost involved manufacturing them and they do have a life span. It was interesting show both vehicles with a fire same can happen after an accident now I have seen EV's after an accident burst into flames that by the time they try to put it out their is nothing left same can happen to a Petrol vehicle LPG less likely the first tests they done was put an LPG vehicle and use 2 trains to hit the vehicle see what would happen, you couldn't even make out what the vehicle was no explosion take stayed full intact had dint's but didn't explode I wonder what would happen with the other 2 they I think would. I feel this huge push by the United Nations and climate change are deliberately missing the point Australia Burnt off millions of tonnes of this a year so why the push for electric somebody is making huge money out of this and it's not us. If you have worked on a Petrol powered vehicle in an enclosed area you eyes start to water and your not feeling to well even with the roller door open where as a LPG vehicle doesn't have the same effect at all. The big point is you don't have to change that much to vehicles of today to run LPG FORD Australia had a pour LPG vehicle in a sedan or wagon people just didn't buy enough of them with scar tactics used Government bodies that had no idea what so ever, to make batteries that have a life span up to 10 years but start losing charge before that time it takes 5 tonnes of material to make 1 tonne of usable material what and who pays for it to be recycled that would be all of us same goes with nearly all so called renewables. Is it because they cannot tax the LPG the way they do with Petrol or Diesel even the waste of water and energy used to get Hygiene is a joke you have it with LPG use it and leave the taxes on it alone.

Ты Гат почему ты взрываеш Опель омегу

Diesel 😉😂😂😂😂

It’s the rate of vaporization. Gasoline is extremely volatile due to the very nature of what it is needed for.

many wrong things about lpg and petrol

Nice propaganda.

Question: If you accidentally crash a car behind the back of the converted LPG car, does it explode or no? I do now know whether my question is real or fiction. Bear with me.

i had lpg on my second car , mazda 626 glx . it was a winter and i had a summer tyres . well , i was drifting with a handbrake on the all corners and then i crashd in to the bus . lpg tank holders on the one side hold and on the other got broken . i was lucky i had no lpg in the tank . otherwise it would be a fire ball
