Erik de Vries uses Lucas Fuel Treatment

I recently bought my F-250. It had 260,000 km on it. The engine idled a bit roughly at stoplights when warm, was otherwise fine. I changed the fuel filter with little effect. I then tried several other "Fuel System" products, including the cleaner/anti gel I normally run in my Volvo Semi Truck in winter. There was a bit of improvement but I wasn't happy and thought I needed a new injector.

Last week I bought a gallon of your product on sale at a truck stop in Washington State. I put half in my Tractor's tanks, and then filled the bottle again with diesel fuel.

I poured this 50/50 mix into the tanks of my Ford, and by the time I'd driven 60 miles, it idled smoothly and cleanly.

I've fueled the pickup several times since then, adding your product only every second fill and it still runs smoothly.

I normally never write testimonials, but you saved me a lot of money and grief.
