    Exclamation Best Fuel Economy

    Hi all,

    I've finally broken, the cost of petrol has finally got to me.... Im now considering all sorts of stuff. LPG conversions, Swapping to a diesel engine, etc.

    Thing is I have a 1.8i Astra Bertone Convertible and get about 33MPG.

    Anyone got any hints generally of specifically about increasing fuel economy. nomatter how menial, they all add up!

    Thanks

    Dom

    service the car regularly, reduce any excess weight in the car that is not needed, only drive with half a tank of fuel as you will be lugging around more weight with full tanks. keep tyres well inflated. i have a 1.8 coupe and average around 36 mpg using total excellium fuel. if you want to swap to a diesel, then try a Corsa. my wifes 1.5D averages 60 mpg, tiss a snail though.

    I dont want to swap as i really like my astra as it is, wondering about the logistics of dropping a diesel engine in the space.

    my average is around 20-25 but at the moment theres not much point changing as you get screwed when you trade it in or sell it with the poor state of the economy. keep it and look at the lpg conversion put if iirc some conversions dont like modded cars with remaps. think thorney had a problem with coming up with a map iirc that is. keep it and just enjoy it as the way its going only the mega rich will be able to afford petrol and running costs of cars

    Courtenay reckon (and one or two others here) on improved fuel economy from their gas flowed/ported cylinder heads - you'll gain a nice few bhp/ftlbs too

    I have a 1.6 16V Dual Fuel Elegance
    It's slower than our 1.8 CDX Petrol but with coilovers it keeps the pace about the same.

    I get about 35mpg on petrol and about 30 mpg on LPG.

    at £1.10 and £0.59 that's 14.3p per mile on Petrol, 8.9p per mile on LPG.

    That's on a par with the ECO4 1.7 CDTI but way faster and far better trim lol.

    It's also A little cheaper on road tax (£10) than the 1.6 petrol, and a lot cheaper than the 1.8 which is £215, pre 2001, or £225 post 2001.
