the motor purr story
​
Many expensive automotive repairs are just cleaning problems in disguise.
​
In 1967, Motor Purr started with a simple idea: many "broken" engine parts aren't actually broken. They're just dirty.
Dirty piston rings cause oil burning and smoking. Dirty VVT solenoids cause rough idle, check engine codes, and worse. Dirty intake valves reduce power, efficiency, fuel mileage, and more. Dirty catalytic converters trigger expensive replacement recommendations.
Clean them, and they work again.
For nearly six decades, we've been developing chemistry + delivery solutions that dissolve deposits, restore function, and save car owners thousands of dollars in unnecessary repairs.
