In 2 days my steering is back to normal. Honest.

My '06 Ford Freestar was gradually getting harder to steer. No leaks and a tight belt so no slipping. I emptied as much fluid as I could and added a bottle of Lucas Power Steering Fluid and Conditioner which the bottle says eliminates hard spots.. in 2 days my steering is back to normal. Honest. It worked for me and its been 3 wks now. A garage near me gave me a price of $569.00 for a new rack installed. I lucked out. For $10.00 a bottle it was worth a try. I'm very happy.

I’ve been using Lucas Products for my vehicles for many, many years now with complete satisfaction.

I've been using Lucas Products for my vehicles for many, many years now with complete satisfaction. I came upon their gun oil many years back while at my local auto parts place while still living in California. Been using it ever since while all the other products I have collect dust.

I added this to the gas and was amazed… it stopped making the sound that I thought was a rod bearing.

My truck engine has over 200,000 miles and a knock started and I thought it was a rod bearing. I was reading the label on the product Complete Engine Treatment and the words, (stops engine knocks.) I added this to the gas and was amazed, and still am, it stopped making the sound that I thought was a rod bearing. I do have to add the treatment to each fill up, but it does work.
