Established in 1984, Cost Effective Maintenance (CEM) provides cost effective methods to correct engine problems such as oil consumption, power loss, hard starting, smoke, poor fuel consumption, blow by and chronic overheating. In 2007, CEM were granted membership status with the Australian Government's Greenhouse Challenge Plus program, which requires members to commit to energy saving pursuits.

Founder, Brid Walker has worked extensively in the mining industry to achieve fuel efficiency benefits in large open cut mining and diesel power generation equipment. He has acted as a consultant to the large Porgera gold mine, in the Central Highlands of Papua New Guinea, where because of the high altitude, diesel smoke emissions were the worst he'd seen. His recommendations resulted in dramatic reductions. With another, a large Australian bauxite mine, Walker guided them to better engine life, by focusing on changes that reduced diesel smoke particulates.

CEM do not promote magical "cure all" products, but specific, purpose built corrective maintenance solutions to a range of common engine problems.

At CEM we are solution driven, not sales driven. Once we know what your problem is, we are in a position to offer you the best advice and real solutions, at a fraction of the cost of a mechanical repair. CEM's problem solving success rate exceeds 90%
