What is a Walnut Blast?

Matipo Garage

A walnut blast typically refers to a procedure used to clean carbon buildup from the intake valves and combustion chambers of a gasoline engine. This carbon buildup can occur over time as a result of incomplete combustion and the recirculation of exhaust gases in vehicles equipped with direct fuel injection systems.

If you notice symptoms such as rough idle, poor acceleration, decreased fuel efficiency, or a noticeable decrease in engine performance, it might be an indication that carbon buildup has become a problem in your vehicle's engine. However, not all vehicles will require a walnut blast, as modern engine designs and fuel additives can help mitigate carbon buildup to some extent.

It's important to consult your vehicle's owner's manual and follow the manufacturer's recommended maintenance schedule. Some manufacturers might suggest performing a walnut blast at certain mileage intervals or when specific symptoms arise. If you're unsure about whether your car needs a walnut blast, it's a good idea to consult a qualified mechanic who can assess your vehicle's condition and recommend appropriate maintenance procedures.
