Goodyear All Turbo is a high performance, heavy duty diesel engine oil. It is specifically developed for low emission vehicles to extend their engine life and oil usage. For example, it can be used in trucks, buses and off-highway applications such as tippers. It provides outstanding soot handling capability and excellent TBN retention to help in countering harmful effects from high temperature and corrosive exhaust gases. These can be caused from Exhaust Gas Re-circulation (EGR) systems.
