How to run a classic V8?

[il-mostro]

I am thinking of buying a classic Rover P6 with 3.5 V8 engine. I am wondering what is the best economical way of running the car, whilst sticking two fingers up at the Government and their Tax etc etc.

Should i go LPG, Wine (like Charles) or any other options? Your advice is appreciated.

Convert it to a diesel engine, and use red.

Most other ways still pay a fortune in tax to the government

Although LPG would be the best legal way to do it.

How many miles are you going to do in it?

Giving it a tune up and removing some of the exhaust/induction restrictions will help it to be more economical as would running some modern tech such as converting to a Megasquirt EFI setup. But it'll cost and improvements are likely to be small.

My TR7 V8 manages 22-24mpg but a Range Rover is more like 12-15mpg. I suspect the P6 will be nearer to the RR than the TR.

As for LPG, well at under 60p/litre it'll make fillups a lot cheaper. But unless you can get the parts cheap and fit them yourself count on around £2000 to buy a kit and have it installed. That means you'll need to do quite a few miles to regain the cost. £2k would buy a lot of petrol.

Scarily 2k buys less than 40 tanks of fuel now!!!

Go LPG, it's an interesting mile muncher to say the least, and unless your planning on doing about 10k a year in it I'd leave it petrol.

You need to use 80 tanks of lpg to get your 2k investment back and start being ahead assuming you get the same MPG out of LPG which you don't usually.
