That petrol emotion

Bad pun of course, but with fuel prices at an all-time high, the economy of certain classics is coming into question on the fleet. Certainly I am finding myself commuting in the Mini more than the Land-Rover lately as the mpg figure is double that of the SIIA.

I even recently read a feature that suggested towing your Land-Rover behind something more economical in order to save fuel costs on the way to a show! That's not really our style however, so I wonder if anyone else has taken steps to improve the economy of their classic - if so, what did you do and more importantly, did it work?

LPG conversions, removing the engine fan and fitting a Kenlowe are two considerations...

As you know Mr P, I have blithely ignored the issue of fuel prices for the past four years in using the Interceptor an unhealthy amount. But now, for the first time, it is really starting to bite at 7mpg on the commute and 110 miles from a 16-gallon tank (that's 73 litres, work that out at £1.40 a litre!). So, sadly, yes the fuel price alone is now so crippling that it does effect my commuting car choice, but i consider myself very fortunate that all it means is that I have to choose instead either 14mpg (in town) Triumph (blame the sprint metering unit), 20mph Lotus Elite or 25mph Lotus Elan. The others are certainly benefitting from the extra use.

If anyone wants to demonstrate the wonders of an LPG conversion on my Interceptor (free of charge, of course, all in the name of research), they are very welcome.

LPG is one possibility on the Land-Rover, but with it being an 88", space is at a premium without having to find room for a large LPG tank!

Of course, a 200TDI conversion mades the most sense for me, but I don't think I could stand opening the bonnet if that lovely original petrol engine went.

 Guys.Talking about fuel, I am currently experiencing problems with modern fuel,soon as my car gets caught in traffic the old girl breaks down and will start until the engine is cool.I know Ethanol has now been introduced to help reduce CO2 emissions.Is anyone experiencing similar problems and if so come up with a solution .I would like to hear from fellow classic car owners.

The only problem I have is with fuel going off if it isn't used and sits in the car for a few weeks or more.

I now regularly end up draining the old car of fuel and putting that into the modern car and putting fresh fuel in.

Fuel vaporisation is always an issue with classics, get around it by either fitting a return line so the fuel is always circulating to avoid hot spots, or fit an electric pump.

Cheers, Eddie

The answer for those of us silly enough to own V8 powered classics is to spend far more time on a bicycle - classic bicycles are as much (if not more) fun than cars in (ahem) countries with good weather.

Regardless, the 25l/100km "economy" of a proper U.S. four wheel drive (sorry, 9mpg) does get a little much sometimes - although my vehicle was improved somewhat by replacing the original Motorcraft carburettor with a modern Edelbrock 4130.  Fuel vaporisation in hot weather, the suggestions about fitting return lines are excellent (although most cars that were US market bound usually had them anyway).  Other tricks like phenolic spacers between the carbs and inlet manifold are also pretty effective.

I'd be genuinely surprised if a Kenlowe electric fan really was more efficient than the viscous coupled fans, especially when you want the fan to actually pull air through the radiator and not just have a shiny black plastic toy under your bonnet.

Thanks Drubie.I have tried all these methods over the last 3 months and still no joy,I hear the EU want to introduce 9.2% Ethonol so when this

happens all classics will be stationary.

What sort of car is it jagnut12?  I'm gonna guess a 12 cylinder jaguar :-)  They used to be notorious in Australia for overheating problems, when I was a kid we snuck up on a fellow traveller at a caravan park in mid summer as he tended to his XJ V12 and were astonished we couldn't see the ground through the engine bay, and gobsmacked by the tiny radiator.  We used to take bets in summer during the late 1970s that the car broken down holding up traffic in Summer was a new Jag with fuming owner standing next to it, steam boiling from the radiator cap.  Beautiful as they are...

I'm not sure the the ethanol based fuel is any worse at evaporating / vapor lock as the ordinary unleaded stuff.  It's demonstrably worse for fuel economy here though - and there have been warnings that the local brew is incompatible with some of the older fuel components made of steel.  It's a completely stupid idea.
