Dave Ward Only Recommends Lucas

I work for one of countries largest auto parts stores. Our “chemical wall” displays 100’s of products from every manufacture one could imagine. I am by nature a skeptic. I don’t believe in “magic in a bottle”. I own a ‘67 GMC Truck that had a very stiff steering gear. For many months I would need to start the truck 20 min before driving to warm up and loosen the gear box. On the advice of a co-worker I added a bottle of Lucas Power Steering treatment to the reservoir. It only took 5 minutes for the gearbox to smooth out! I have never seen a product work so fast and so well! At my work, customers rely on sound advice and recommendations regarding solutions to their vehicle problems. I ONLY RECOMMEND LUCAS PRODUCTS! That’s it. Only Lucas. Knowing that I have personal experience with 3 of the 4 Products we stock makes it easy to suggest Lucas products.
