Royal Purple Max-Restore High Mileage Fuel System Cleaner
Royal Purple Max-Restore High Mileage cleaner is a highly concentrated, high performance fuel treatment that is specially formulated to solve performance problems typically found in higher mileage vehicles. It restores fuel economy, extends engine life, lowers emissions, and delivers maximum cleaning power.
