AVYOL has in its range wide variety of diesel engine oils suitable for use in Medium to heavy duty commercial vehicles meeting the specifications of API CF4, CH4, CI4 and CK4 and in viscosity grades 10W-30, 10W-40, 15W40, 20W-40.Read More
The main driving force since 1990 for the development of the entire API commercial "C" diesel engine oil classifications (for example, CF-4, CG-4, etc.) is the concern over the environmental impact of diesel engine emissions. Modern diesel engines are designed to be more efficient and longer lasting than previous generations, so they have tighter clearances and closer tolerances, and tend to run hotter. It’s more important than ever for engine oils to be resistant to oxidation, shear, and aeration. CK-4 and FA-4 oils, the latest evolution in engine oil technology, were designed specifically to withstand these demanding conditions.
The trend is towards lower viscosity grades to meet the needs of next-generation diesel engines and help improve fuel economy. API CK-4 and FA-4 oils both provide improved oxidation resistance, shear stability, and aeration control over CJ-4. CK-4 and FA-4 oils are a clear improvement over previous generation oils, but it is imperative for fleets to use proper oils in each vehicle. While CK-4s are backward compatible, FA-4s should only be used if the manufacturer specifically recommends it for the engine in question.
With the recent emission regulation mandate of the Indian Government to leapfrog from BS IV to BS VI , AVYOL has in its range the low SAPS oil that meets latest API CK4 performance levels, which is compatible with all after treatment devices.
AVYOL has a Low Viscosity Fuel Economy Engine oil which is expected to give Fuel efficiency when used.
