(6 pack) Thermocure by Evapo-Rust Cooling System Rust Remover and Flush

My husband got this to try to help improve the performance of an older diesel tractor. This tractor is 20 years old, but it is very well maintained. There are times it tends to smoke a little, when first started after not being used for a time. By using this product his hope is to try to clean the system a bit and help the engine run more smoothly. He added this, then bushed hog for a few hours. The next time he cold started the tractor there was no smoking and the engine ran a little more smoothly. He has used several kinds of Lucas products in various pieces of equipment on a small family farm and has always been pleased with the results. Maintenance is important to us to try to avoid expensive equipment problems. For the price, this seems to be a good investment.

My engine is more quiet. I used this in my 2010 SUV 2010. One bottle and my chine is running smoother and sipping more diesel rather than guzzling. If your reading this I think you should go to Walmart yourself and experience this product

Other than posting a pic of our diesel truck which I am not sure would help I love this product. Fill your tank up and empty the whole bottle in. I use this regularly. Helps keep the motor running smooth, gas mileage up, and sounds better. Our truck is a 1994. Perfect motor condition. Recommend!

It is one of the best in class to clean the fuel system on Diesel vehicles…. Easy to use and fast acting. Just added it to my oldie PASSAT-TDi and saw big difference in improved pick on acceleration and gain of power.. I am happy that I had it.

I love Lucas products because you can always count on them. It was definitely time for my diesel to have a little help, so trying this diesel oil cleaner was great. I really can't tell exactly what it did but I do know that my truck sounds better when running it. I will definitely give this product to try it again.
