When fuel, especially E5 was much higher than it is now I began looking at ways to improve my mpg. Now the MX5 has never been class leading when it comes to mpg, being a convertible does not help, but as this car is my daily driver I took interest in the Xcelerate Fuel Tablets my brother had tried and was selling to his friends. As a sceptic I decided to keep a log of the mpg, which I show below.
6 tablets were £30, and these can be broken in half, as each tablet does 80 litres so half is needed per fill up costing £2.50 a time.
I was told to expect a drop in consumption initially as the tablets cleaned the engine and this was born out in the chart. The main benefit I found was improved performance , especially pulling up hills. The engine seemed smoother and pulled away with very little throttle compared to before.
If anyone is interested in learning more or trying them my brother Paul can be contacted on PM me for details
