There's plenty of calculators on the Web. Last time I checked you needed to do about 18k+miles per year to get the benefit.
my mate has his vaux astra turbo on LPG he says there isn't that much of a difference in power so recommends it to anyoneWhy dont you get it LPG converted ? If you do the maths it will work out fairly cheaply over 2 years + assuming you do 10k + a year. A BRC kit (top make) costs about 1200 quid for a 4 cylinder so cant be much more and if you fancy it, you can always DIY which probably cuts the price in half.. Oh did i mention gas is 80 odd p per litre and MPG and power difference are marginal if tuned correctly.
I have just changed to diesel for a few months while i save for a new car, I had a 8L S3 that did 22 mpg ish and the diesel Golf i am driving at the moment is doing 45+mpg with no problems, I am saving over £40 a week in fuel!
I'm not really liking the way it drives but its saving me £160 a month in fuel.... Make your own mind up
On the other hand i'm saving for a 2.5L petrol turbo so my saving will be short lived...
Ha that figure makes me laugh as surely it depends on the vehicle. It would have to be a pretty boring petrol to keep up with most diesels economy wise.
If you want to save money it's simples, buy a diesel. The outlay will be slightly more but it will hold it value far better than any petrol equivalent.
It's all what you can put up with isn't it? I've had turbo diesels & just adore my S3, but quite enjoyed the peaky power delivery of the 130 bhp 1.9 PD diesel Seat Exeo (old A4 in a spanish suit) hire car that I was driving around today.
I'm trying to choose now between a new Golf GTi or a GTD as a company car. Heart says GTi, but head says GTD with its lower BIK tax costs. Test drives may beckon...
The higher initial cost of the diesel car, combined with higher costs of diesel mean you have to do a lot of miles for the benefit to make much difference.
However, on a decent Turbo car you are running super unleaded which its more expensive than diesel anyway. Do your own calculations and see the difference. To get a decent power diesel the servicing costs are usually higher as you're looking at a 3Ltr.
I did the calcs when I got mine, I do about 12000 miles a year and there was little difference in total monthly costs. Higher revving petrol was more fun for me...
LPG sounds good but I cannot see them holding their value like a Audi or BMW diesel.
Im not fussed about paying the price to run the r32, just fancied something different. I thought as it been a diesel it would work out cheaper in the long run, but i dont really do that many miles, so would i be better of sticking with petrol? i may look into the 2.0t a3 or just go for s3 instead
Your initial post suggested it was all down to expensive running costs. Anyway just do a simple calculation then..
Petrol car with 7k / year @ 25 MPG cost £1688 @1.34 / Litre
Diesel car with 7k / year @ 40 MPG cost £1071 @1.36 / Litre
LPG car with 7K / year @ 25 MPG cost £982 @ .78p / Litre
Yes if comparing to petrol, I was comparing lpg to diesel
Depends on the age of the motor too. The new 2.0T (211BHP circa 2009 on) engines quote combined consumption at around 40 mpg, whereas my 2.0 TDI (143 BHP, 2009) I actually average only 40 mpg, but then it is the multitronic.
I'm sure the 2.0T doesn't really get 40 mpg, but it will not be far off if driven sensibly. But then petrol is 8p cheaper per litre where I am, and the cost of the petrol car will be cheaper in the first place (more than likely), so overall it would probably be cheaper for me to go Petrol.
If your looking around 2003-2008 motors though, you are probably cheaper with diesel.
