Poor mpg -low mileage car
I have a 1995 Lexus LS400 done 80000 miles. I only do about 2000 miles per annum. I am getting less mpg than I used to. An item in Sunday Times motoring section advised a reader with similar problem to use a product such as PowerBoost to clean the engine which may be clogged up with carbon etc. Can this really work or should I look for other problems on my car? It is running perfectly (apart from the worsening mpg) and is fully serviced and passes mots on emmissions with no problem.

Use Shell V-Power petrol exclusively as this will clean up the combustion chambers and the engine needs 99Ron anyway. Not running it on 99Ron is what cased your problem.
Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.
Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
Our Fuel Cost Calculator shows you which will be the best choice for you.
Compare the running costs of petrol, diesel and electric cars to make the right choice for you.
