Stricter emission and economy regulations around the world have driven leading car manufactures to introduce newer, more powerful and efficient engines such as Turbocharged Gasoline Direct Injection (TGDI) or Gasoline Direct Injection (GDI) engines. These engines require an improved engine oil in order to protect them from a phenomenon called “Low Speed Pre-Ignition” or LSPI. Using the wrong type of engine oil can lead to catastrophic engine failure. However, many vehicle owners are not aware of this and consequently may choose the wrong oil. Managing LSPI requires improvements in engine lubrication chemistry. These requirements are explained below.

 GOOD NEWS - VALVOLINE IS READY

 IT’S ALL ABOUT EFFICIENCY

In order to meet emission and fuel economy regulations, vehicle manufacturers have made a number of changes to their engine designs. These include downsizing, introducing gasoline direct injection (GDI), turbocharging and gasoline particulate filters (GPF). Most new passenger cars and light commercials from leading vehicle manufacturers come with these new generation engines. The needs of these engines are different and require higher-performance engine oils that aid in fuel economy, provide emission system compatibility, protect against low speed pre-ignition (LSPI) and aid cleanliness by fighting turbocharger deposits.

PROTECT YOUR VEHICLE

Vehicle owners have an expectation that the engine oil used will protect their car engine and meet it’s lubrication requirements. However, it is important to note that older oil specifications such as API SN/ILSAC GF-5 and earlier will not meet all the performance needs of these modern engines. While ILSAC GF-5 addresses fuel economy and deposit control, for these modern engines, LSPI protection is also required. Engine oil needs to deliver on all three of these important performance characteristics.

 Usage of older generation engine oils (API SN/ILSAC GF-5) in such modern engines can lead to catastrophic effects. Industry bodies have recognised this and have launched the ILSAC GF-6, a new specification which is designed specifically to protect modern engines.

 To demonstrate the difference, a field trial was conducted in two identical cars – both having modern gasoline engines. One car was filled with older generation engine oil and other with ILSAC GF-6 oil. A comparison of their pistons clearly showed the impact the wrong engine oil can have on engine components.

Valvoline is ready and will be shortly launching an improved range of fully synthetic higher performance engine oils which meet and exceed the performance of ILSAC GF-6.

 A STEP-UP IN QUALITY

Valvoline engine oils with ILSAC GF-6, will be a significant boost in performance characteristics. Reformulated to pass stringent engine tests for fuel economy, LSPI, chain wear, sludge and varnish, oxidation and deposits, wear and corrosion limits. The chart below explains the benefits vehicle owners can expect over earlier generation GF-5 oils.

 

STAY PROTECTED

It is important workshops and mechanics vehicle are aware about these changes and more importantly, what they mean for vehicles. Next time you buy an engine oil or arrange to have your car serviced, make sure you choose the right quality engine oil and understand the reason behind it.
