Description

Made from soybean oil, Schaeffer’s SoyShield boosts diesel engine performance. SoyShield’s gentle solvent action keeps injectors free from deposits, gum and varnish that cause inefficient operation. SoyShield disperses existing deposits throughout the fuel system, safely removing them to the combustion chamber where they can be burned cleanly and completely. SoyShield meets DW10 specifications.
