Is Lucas fuel treatment safe?
I have been using Lucas upper cylinder lubricant/fuel mileage improver that comes in a 32oz bottle for about 7 tanks now. It has given me a couple more mpg but I was wondering if it is safe to use lucas fuel treatment for the rest of the life of my vehicle. Anybody else use this stuff?
