Fuel Saving Tips
In a diesel car pour 0,75L bottle of white spirit (uk) into the tank 20-30 miles before filling up (cheapest in Home Bargains). White spirit is virtually the same as Liqui Molly Diesel Purge but for the fraction of the cost. Helps with a rough idle and improves spray pattern of the injectors if they are gummed up.
