At 1000 miles per week i wouldnt be looking at either an M3 or RS4. The B5 RS4 will suffer seious wear on the cams and the B7 RS4 will get very dirty (inlet manifold) and starve the power you think you have. The m3 just isnt practical and the rear tyres are gonna dissapear as quick as the fuel. On top of that add the RS / M-tech servicing / tyre / brake / fuel / etc costs and your gonna wish you'd bought a 335d or an A4/6 Deisel. Just my two penneth!

agreed.

a 3.0 Audi tdi or 335d BMW would be a much better bet. map them and both will go north of 300bhp and still return 45mpg on a motorway run, 35 average.

Never seen an RS4 on gas but the couple of S4s I've seen have been perfect before the install and trouble afterwards...

Unless its factory fitted (some volvo's and GM stuff from a few years ago) Gas conversion are always trouble.

The gas fitters always say, its and engine management issue nothing to do with us, take it to the dealers.

We say, the harness has all been chopped about and there is loads of non standard suff on it, it must be down to the Gas people. Very very difficult to diagnose even simple running faults.

I've driven a lot of LPG cars and most of the time they run fine, but when they don't, they are a right pain to get sorted.

Thanks guys i like the sound of those diesels and re mapping esp with 45mpg on motorways.

Thanks again

We had a rs6 on lpg .. Ran very well .. I think it made 500bhp on the gas without a remap..
