False Economy

Sir,

I find it difficult to understand the present rage for cars using Regular 2 Star petrol as perpetuated in your April Editorial. Is it not realised that such cars are less efficient?

If all cars in England needing Super were suddenly changed over to use Regular we would use between 10 and 20% more petrol.

Back to the old 10 or 11:1 compression ratios, I say.
