Sea Foam Testimonial

Tree work is tough and demanding work. Because every minute matters, the success of my business always depends on our engine equipment to run in top shape, from saws to heavy duty grinders and hauling vehicles.

Two years ago, Sea Foam Motor Treatment was recommended to help overcome rough idle and heavy soot exhaust problems we were experiencing with a diesel stump grinder. The Sea Foam results were immediate and caused a night & day improvement! We’ve been running Sea Foam Motor Treatment ever since.

Today we run Sea Foam in all of our equipment, from the pickiest of small gas engines to thirty-thousand dollar diesel engines. Everyday we’re reminded by minimal diesel exhaust, smooth running, and steady idles, even at below freezing temps.

Thanks for your product!

Sea Foam Testimonial

Like any careful mechanic, I always look for the cause and effect on any repairs that I do, which led me to Sea Foam Motor Treatment.

I remember going to my local NAPA store to study everything they had on the shelf. This is when I found Sea Foam Motor Treatment. Since that day, your product has proven beyond any doubt that it does what it says it can do! Nowadays, my diesel starts quick and runs better than ever, and I seldom see carb problems in the small engines that I service on a regular basis.

Why? Because I tell all my customers that Sea Foam Motor Treatment is a must use!
