Performance Analysis
No change in performance.

Oil Analysis
For the first time since the 5,000-mile checkup, there is no fuel dilution! All other fluids are protecting as they should be and our technicians ran another can of BG 44K® through a tank of gas for optimum protection.

Borescope Analysis
As you can see, the deposits are starting to build up again on the intake port walls and on the back of the intake valves. We expected this to happen because, in a Gasoline Direct Injection engine, fuel is sprayed directly into the combustion chamber and bypasses the intake port/valve area.
