Preventing Engine Deposits

TEOST Test EngineAccording to industry experts, 38 percent of vehicles sold in North America will be turbocharged by 2019. Turbochargers push more air into the engine’s combustion chamber, providing better fuel economy and performance, but also creating intense operation conditions.

Deposits caused by high engine temperatures can lead to a host of problems. Pre-ignition and engine-knock, reduced fuel economy and power are frequently traced back to excessive deposits. AMSOIL Signature Series 5W-30 handles heat so well that it protects turbochargers 72 percent better than required by GM’s dexos1® Gen 2 specification.*
