Carbon buildup is slowly and invisibly destroying direct injection Subaru engines, and professional walnut shell blasting costs $600 to $1,200 every 40,000 to 60,000 miles. Over the life of a 300,000 mile Subaru that adds up to $7,200 in cleaning services alone. But there is a free driving technique that raises intake valve temperatures high enough to burn off carbon deposits before they accumulate into hard layers, extending your cleaning interval from 40,000 miles to 80,000 miles or more. In this video I explain exactly what the technique is, the combustion science behind why it works, how to do it correctly on naturally aspirated and turbocharged Subaru models, and what to combine it with for maximum effectiveness.
