That Lucas Super Coolant is just another one of your OUTSTANDING PRODUCTS!

Dear Forrest,

I have to write you about your Lucas Super Colant. I recieved my sponsorship package and this year I ordered the Lucas Super Collant. I am amazed. I have bought a similar type additive from the shelf in the past... it never worked as stated; a waste of money.

However, I have a 73 Nova that I am about to drive from Massachusetts to Michigan next month. When it idles it tends to run hot about 220. Driving wasn't a problem, just when I sit still. I tried Lucas Super Coolant and to my amazement IT DID EXACTLY AS STATED!! I ran that car several times for hours at idle and I couldn't go get it to rise above the normal 190 temperature.

That Lucas Super Coolant is just another one of your OUTSTANDING PRODUCTS! I can't wait to tell all my friends on and off the track. It works! I am ready to drive my Nova west to my shop. Thank you.
