Lucas Diesel Deep Clean is a new Lucas technology developed to reduce the cost and hassle of particulate filter maintenance. It is an excellent preventative maintenance product. It causes the fuel to burn much cleaner, thus eliminating a lot of particulate matter that would otherwise go into the exhaust system causing “regens.” It also cleans out much of the matter already trapped in the filter. This eliminates exhaust backpressure allowing the engine to run easier and cooler as well as lowering the aggravation and down time associated with particulate filters.
