GDI Engines Equal New Service Opportunity for Repair Shops

A large percentage of recent model vehicles have GDI or gas direct injection engines. In fact, these engines are found in almost half of the new vehicles sold today. As a result more and more GDI engines will be rolling through the bay doors of your shop. While GDI engines are more efficient and deliver more power, a common problem with these engines is the buildup of carbon deposits on the intake valves. This opens up some unique opportunities for automotive repair shops: You can help your customers while increasing sales.

GDI Engines

GDI engines inject the fuel directly into the combustion chamber. This means that fuel and additives never wash over the intake valves and clean them as they do in a PFI (Port Fuel Injection) engine. The result is carbon build-up on the valves, which can lead to a whole host of problems. The most common is decreased power. Other symptoms may include cold stalling and cold-start difficulties, NOX emissions test failures, and excessive ping on acceleration. In some cases, cylinder misfire codes from one or more cylinders can be caused by carbon buildup. If the buildup reaches a severe enough level, the Check Engine Light (CEL) may turn on as well.

The need to prevent and remove carbon buildup from GDI engine intake valves offers your shop a unique opportunity to sell this service to GDI vehicle owners.  Older methods of removing carbon buildup are time and labor intensive, requiring engine teardown.Newer methods use advanced chemical technology to safely remove the carbon. CRC GDI IVD® Intake Valve Cleaner is a new product that is sprayed directly into the air intake system and hits the back of the valves with PEA (Polyether Amine) detergency at 150X the concentration of any premium fuel additive.  This new product is safe and effective for all engine types, including turbos, and is especially efficient for cleaning GDI intake valves without disassembling the engine.

The regular use of a specialized valve cleaning chemical like the CRC product protects the engine valves from accumulating hard carbon deposits which can break off and cause damage to the engine and other components such as the catalytic converter.

For hard carbon, the service is very time consuming and involves removing the intake manifold to expose the head’s ports and performing a form of soft media blasting, usually walnut shells or plastic beads. The carbon is then removed using a shop vac.

You can save your customers from this costly process by offering an effective yet less time-consuming and more affordable chemical treatment, gaining their trust and encouraging repeat business. Educating GDI vehicle owners about the importance of regular intake valve cleaning will help them keep their engines running efficiently and prevent bigger problems down the road.  Suggest preventative maintenance with CRC GDI IVD® Intake Valve Cleaner every 10,000 miles, or with every oil change.

GDI is a great technology that delivers increased power and improved fuel efficiency. The explosive growth of GDI engine vehicles also presents your shop with an important new revenue opportunity.
