Lpg...cost v time

[nikroc]

I've been quoted £1700 for a conversion and am trying to work out if its worth it.

I put an average of £30 a week petrol in my car and this gets me approx 130 miles.

The cars an 03 plate,2t and got 70k on the clock and drives like a dream and still makes me smile when i drive her..so the qusetion is how long would it take to 'recoup' the outlay based on my current use.

I have no plans to get rid of her.I change the oil and filter every 6 months so im not expecting any problems,but who knows.

What do you think?...

I really don't think you do enough miles to recoup. It would take 2.5 years to break even on current prices. Knowing this government, LPG will get hiked as more cars begin using it.

£30 x 52 week = £1560 (£1.329 per litre on unleaded)
£16.68 x 52 week = £867 (£0.739 per litre LPG)

£1700 divided by £867 = 2.45 - so 2.5 years

Impressed am i at your math..thanks for replying.

I would suggest increasing the petrol price by 5p per litre each year (to take into account cost changes and the twice a year duty changes)
Equally, LPG is expected to increase in cost substantially next year, taking it to around 85p per litre

As above, I would only recommend installing it on a car with more than 60K miles if you expect to cover a high mileage
For other cars, with less mileage, then it pretty much always makes sense
The days of diesel being cheaper than petrol are long gone now

I wonder how much id 'save' in road tax?..might help offset the price. Plus I intend to up the miles next year as I have retired and will be going fishing more often.

You could buy the kit from Tinley tech for about 500ish, and fit it yourself, it's really not hard. Then once fitted have an LPG specialist certify it.
Most Land Rover owners do that.
You'd probably save yourself £1000

i think it good idear, especialy like the other poster says if you can buy it cheaper, could also possibly transfer it to another vectra should anything happen to your existing car.

There would be very little saving, if any
As a 2006 it would remain on the current Tax Band, due to emissions rating, unless it tested with a lower emissions rating (very unlikely)
Unlike older cars which could swap from petrol to dual fuel
This is also one of the reasons the LPG grant was scrapped

Shes a 2003 ...

you save a tenner a year tax iirc

also the guy who worked out 2.5 years, actually would take longer. you;ve just worked out that he will spend half as much on lpg as he does on petrol. whilst the price per litre is roughly half, you get slightly less mpg on lpg. the car will usually use slightly more lpg to go the same distance as it would petrol. not a lot more but a bit.


also if the car is a 4 cylinder you shouldnt be paying anywhere near 1700 usually 1000-1200 is more like it.
