Petrol vs Diesel vs LPG vs Hybrid - pure math
Discussion
Over last 10 years of all money I spent on car depreciation, petrol and insurance, I spent roughly 60% on fuel, 30% on insurance and less than 10% on car depreciation and repairs.
Therefore I am thinking very carefully on how to reduce mpg on my next car.
Here is my question:
If I spent £100 driving a petrol car 70% in town and 30% on motorway, how much on average would I spend driving same type of car on same route but:
- with a diesel engine
- with LPG
- hybrid (and not plug in hybrid)

For diesel V LPG it's a no brainer unless you need the low torque of diesel for heavy towing - LPG is far cheaper to run
Compared to elec it starts to get complicated - as you can't buy strictly comparable cars nor can you buy cheap / old hybrids.
If you want to run a new(ish) car and can cope with the range restrictions etc - currently I'd expect elec to be cheaper although it would depend on the cars / mileage etc.

70% in town driving? Buy a bike! (pedal powered)
Well, I would bike is good for 90% of in town journeys. But the harsh reality I would still need a car for the remaining 10%.Renting a car on demand / car club /public transport etc is not really an option as it will turn up more expensive than just having a car.

The great thing with LPG is you can have a big lazy V8 with good amounts of power and still get the same cost per mile as some horrid 4 cylinder diesel.
The bad thing about lpg is that you have to pay someone in Romford with half his teeth missing a 4 figure sum to drill holes in your v8's manifold and cut up bits of your wiring loom.p0rcupine said:

What type of Hybrid Petrol or Diesel?Therefore I am thinking very carefully on how to reduce mpg on my next car.

LPG or petrol (if you dont plan to drive around much) all day everyday..
I have 2 LPG cars,
one Jazz - consumes 6litres of LPG per 100km , one litre is 50p .. do the maths, way cheaper than Diesel + ON PAR WITH Electric car! I have no reason to even wait for electric car when my old ass car already has fuel expenses as a electric car..
other big ass minivan with 3.2litre engine, consumes 12l of lpg/100km , again cheaper to run than anything diesel + way more reliable!

75 and 75? Why then everyone is hyping on hybrids if they are no better than diesels in town and worse than diesels on motorways?
If LPG is that much better why so few motorists are actually using it even in my area with enough LPG stations?
because everyone leases car nowadays and no1 wants to put on their brand new car a ''stinky''' , ''unsafe'' LPG system.If LPG is that much better why so few motorists are actually using it even in my area with enough LPG stations?
+ hardly anyone even knows what is LPG
LPG all day everyday for me...Costs of an electric car + way more reliable and way more cheaper to service than a Diesel car.
My next car probably however will be a Petrol Hybrid ( Auris or something like that) ,it does suck a bit to search for LPG stations when you are traveling abroad.

tters and then scrap them for more than i bought them for so although i'm a special case it is perfectly possablep0rcupine said:

hybrid isnt really that great in fuel savingIf LPG is that much better why so few motorists are actually using it even in my area with enough LPG stations?
drove a Auris 1.8 hybrid for about 6 months, first 2 months i done 90% motorway, i got combine 42-43 mpg which is worse than a diesel of same engine size, then 4 months with 70% city combine only slightly rise to 48.X mpg
drawbacks of the hybrid are stuck with CVT, smaller boot and not took forever to overtake a lorry in motorway
Practicalities of running a real world car aside, I wonder if anyone has tried LPGing a hybrid (perhaps Atkinson cycle) engine. You can in theory run a fuel cell off LPG too, which might make an interesting power augment.
When you are doing the mathS, you need as much information as possible, consumption, fuel costs, depreciation, repairs etc. Without knowing your particular circumstances, it is difficult to say. e.g. at one end of the scale, for someone doing just occasional local runs, then a taxi would be better. Someone doing lots of miles would possibly see more benefit from a Bluemotion type vehicle, but these are obviously newer/more expensive. The devil's in the detail.
LPG is certainly a strong contender if you are doing a fair few miles, the trade-off is in sourcing and fitting a good quality conversion.
