Exxon XD3 ready for EGR
ExxonMobil has reformulated its Exxon XD-3 EXTRA heavy-duty engine oil to meet API's CI-4 standards, which go into effect this fall. The oil has been enhanced to handle the tougher operating environment anticipated with the introduction of exhaust-gas recirculation (EGR) engines designed to comply with EPA's stricter October 2002 emissions rules.
According to ExxonMobil, the new formulation will tolerate the high heat of EGR-equipped engines; reduce the need for make-up oil; offer stronger TBN retention to neutralize more acids for improved engine protection; and provide longer drain and overhaul intervals.
