GDI Solved!

For those interested in a short overview of the gasoline direct injection engine, you can find its history documented nicely in Wikipedia about as fast as you can type “GDI engine.”
Wikipedia’s bullet points include the fact that this engine technology has been around since the turn of the century but was not perfected until about a hundred years later. And the technology is still evolving, in both design and its required maintenance.
Wikipedia is never shy about including the bad along with the good and they do that under the heading “Drawbacks,” in which they state:

“When fuel is no longer being sprayed on the intake valves, small amounts of dirt from intake air and blowback carbon from the crankcase ventilation system cakes on the intake walls…”

Without the whole story, this drawback could turn into a reason for consumers to step back from direct injection. It’s also widely known that Wikipedia is not always accurate or up-to-date. So we’d like to give the rest of the story.

What is an ounce of prevention worth?

Every BG GDI Performance Service includes 44 ounces of prevention and that could be worth hundreds in fuel savings and repairs.

Fuel and oil system cleaners used in the BG GDI Performance Service reduce and prevent the conditions that lead to deposit formation. This service cleans nasty fuel and oil deposits on piston rings using BG EPR® Engine Performance Restoration®, PN 109.

BG Advanced Formula MOA®, PN 115, keeps carbon dispersed which keeps oil from sludging and deposits from forming. The entire fuel system is kept deposit free using BG 44K®, PN 208.

Hard fact

Once carbon accumulates on the backs of GDI intake valves, there is no pour-in-the-tank product that will remove these deposits. It’s physically impossible to use tank fuel system cleaners to remove deposits in the air intake of a GDI engine. And that’s the hard, baked-on truth about GDI.

The Cure

The BG GDI Fuel/Air Induction Service delivers the same benefit that the traditional BG Fuel/Air Induction Service delivers in port injected engines. Using BG Fuel Injection & Combustion Chamber Cleaner, PN 201, 2 cans of BG Platinum® Air Intake, Valve & Combustion Chamber Cleaner, PN 261, and BG 44K®, PN 208, together is what makes this service such a powerful solution.

BG GDI Air Intake and Valve Cleaner, PN 260, softens and removes intake deposits moving them downstream while BG Fuel Injection & Combustion Chamber Cleaner, PN 201, cleans fuel injectors and combustion chambers, restoring lost performance. With the BG 22 VIA™ Vehicle Injection Apparatus , PN E101-1178, the technician can remove harmful deposits without the complete disassembly… Or as one OEM has done in the past, a cylinder head exchange program.

After the service, further driving allows BG GDI Intake Valve Cleaner to soak in and remove the deep layers of deposits in a layer-by-layer fashion.

A BG GDI Performance Service is recommended following the GDI Fuel/Air Induction Service.

“The BG GDI Fuel/Air Induction Service is THE cure because it’s a complete service that has been tested on GDI engines to ensure the right equipment is used to disperse the exact volume of chemistry, to the specific location needed, for the most accurate amount of time required.”

Jay Erwin, R&D Manager, Tools & Equipment
Dustin Willhite, BG Technology Director, believes addressing deposits in a GDI system is tough business. “These new products are very unique. Having the right chemistry is just one part of the service. Product application and service procedure are absolute key to service effectiveness.”
This may be the maintenance that saves the GDI engine from further drawbacks and gives service facilities the chemistry and tools to offer their customers. First, the BG GDI Performance Service will protect against deposit buildup and for those vehicles who don’t use BG’s 44 ounces of prevention, the BG GDI Fuel/Air Induction Service removes deposits and keeps GDI engines running at peak performance.
Now that we cleared that up, these services may need their own Wikipedia page.
