HEAR IT FROM OUR CUSTOMERS

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.

AMAZING PRODUCT!

My family has used Lucas oil additive for years, from our vehicles to our semis. After hearing several opinions from others, as well as my own family, my boyfriend decided to give it a try. He is a die hard Lucas believer now! Earlier today he had an issue of his oil filter failing on his truck and causing most of the engine oil to spill out. We went essentially a mile before the oil pressure gauge started to drop & he coasted it onto the side of the road. The oil that was under the truck was a tackier feeling than before when he didn’t add the Lucas Oil Additive. While we sat on the side of the road he exclaimed “Lucas has my business forever. Their oil additive just saved my truck!

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.

I Added The Lucas Oil Stabilizer and There Was an Immediate Result.

I have always had a loud top end on my Harley Sportster. And ever since I started using this oil [Lucas 20w50 Motorcycle Oil], my engine is quieter and have noticed much better my motorcycle is running overall. I added the Lucas oil stabilizer yesterday and there was an immediate result. I LOVE Lucas products and as a motorcycle mechanic for Harley Davidson, I tell everyone I know with Harley’s to use this oil. -
