Stricter emission and economy regulations around the world have driven leading car manufactures to introduce newer, more powerful and more efficient engines; Gasoline Direct Injection (GDI) and Turbocharged Gasoline Direct Injection (TGDI). These engines need a higher specification engine oil in order to protect them from “Low Speed Pre-Ignition” or LSPI. In simple terms LSPI is early combustion in the engine which can lead to catastrophic engine failure. To prevent LSPI requires improvements in engine lubrication chemistry. These requirements are explained below.

 

PROTECT YOUR VEHICLE

Vehicle owners have an expectation that the engine oil used will protect their car engine and meet its’ 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.

LSPI is an abnormal, uncontrolled combustion event that can occur in modern Gasoline Direct Injection (GDI) and Turbo Gasoline Direct Injection (TGDI) engines. At a minimum, LSPI can generate an audible knocking noise noticeable to the driver and prevent the engine from operating at optimum efficiency. More severe LSPI can cause engine hardware failure, including damaged spark plugs, pistons and even catastrophic engine failure, leading to user disruption and high vehicle repair costs.

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

 

GOOD NEWS - VALVOLINE IS READY

Valvoline products with ILSAC GF-6 specifications have been available to the market since the first license date in May 2020. In November, Valvoline also upgraded numerous engine oils to API SP to ensure our customers benefit from the latest industry specifications.


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.

 

 

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