Do you think engine oils are all the same, and buy the cheapest

Posted by Ashley Wilson on

Many people think engine oils are all the same, and buy the cheapest.

Knowing OILS AINT OILS ....Oil quality in fact varies greatly. Lower quality oil will have a shorter working life. Its impact on your engine will be higher fuel consumption and emissions. Ultimately it will shorten your engine’s life. Perkins diesel engine oil (DEO) is the only oil formulated specifically to match the conditions in Perkins engines.

Using a good quality oil is genuinely better for your engine. Choosing cheaper oil is a false economy because it will leave you with greater costs in the long run for repair and maintenance. A good oil, on the other hand, will maximise engine life, control emissions and reduce the cost of maintenance.

Oil’s key role is to lubricate the engine and remove heat. With increasing emissions standards and demands for power efficiency, engine oil has to work harder than ever to protect your diesel engine. 

Maintaining performance and protection

As well as lubricating and removing heat, the oil reduces engine wear by preventing the build-up of deposits and sludge. With lower-quality engine oils, the levels and quality of additives can be significantly lower, dispersant levels may mean ash and deposits may not be kept in suspension, allowing them to stick to piston and rings. These deposits can attach to pistons and rings, causing cylinder wear, resulting in reduced performance, increased fuel consumption and potentially increased emissions.

Lower oil quality can also lead to problems, with lower levels or lesser quality antioxidants allowing faster oxidation and oil breakdown, producing black sludge and varnish, increasing viscosity and rust and corrosion.

The sludge can block galleries in your engine, leading to hot spots and poor lubrication – problems that cannot then be removed by an oil change.

Custom formulation

Designing an engine oil to meet the API or ACEA standards is a compromise of balancing the additives, for many different engine types, applications and operating conditions. Perkins DEO has been specifically formulated to ensure long life in Perkins engines, with additives specially selected to resist oxidation, prevent the build-up of deposits to give long lasting protection


Perkins approves and recommends Perkins DEO 15W-40 API CI-4 as the only oil to use in Perkins engines, EU Stage IIIA/U.S. EPA Tier 3 equivalent and below.

“We’ve created Perkins DEO to give you unbeatable protection and unrivalled engine performance and the results have been proven in elevated condition testing.”
