Tribological Study Of Ps-23 For Possible Automotive Applications, Roberto R. Carballo

FIU Electronic Theses and Dissertations

PS-23® is a new oil conditioner developed in South Africa by Lubrioil S.A. Chemical and physical analysis, and experimental studies were conducted to investigate the possibility of using PS-23® as an engine oil additive package. Mobil 1OW-30 is used as the engine oil. The experimental results indicate that PS-230 contains unexpectedly high levels of calcium and phosphorus, and that mixing 10% PS-23® in volume decreases the lubricant viscosity and increases its volatility. The start-stop tests using small engines were used to test PS-23® in a severe operating condition. The experimental observation suggests that under such an adverse combustion environment, the …
