Is The Cheapest Oil Always The Best ?

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

OILS AINT OILS ….Sol is a old quote on TV in the 1970s

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, emissions and engine wear. Ultimately it will shorten your engine’s life.

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.

We always recommend to go back to the manufacture and see what oil they recommend . Especially if your vechile is still under new car warranty.
