If your customer has a turbocharged engine that’s “knocking,” it could be LSPI.

LSPI is low-speed pre-ignition, also known as low-speed engine knock. It’s one of the most common problems found in today’s turbocharged GDI engines.

It typically occurs in low-speed/high-load driving conditions – for example, driving slowly and then rapidly accelerating, like you would when merging onto a freeway.

Research suggests that components of the motor oil mixed with fuel in the combustion chamber prematurely ignites the fuel before the spark plug fires. The result is an uncontrolled combustion that hammers down on the piston with massive cylinder-pressure spikes – causing severe and often catastrophic damage.

Lubegard Engine Oil Protectant for turbocharged engines is specifically formulated to reduce and prevent LSPI and protect engines and engine parts from constant knocks.
