Abstract: Use of turbochargers to improve small engine response and fuel efficiency is growing rapidly and requiring proper engine oil formulation to prevent a type of deposit similar to coke from forming after the engine is shut off. The TEOST 33C instrument and test was developed to simulate turbocharger operation and this paper is a world stud of present engine oils regarding their response to this turbocharger-simulating deposit test.
