Newly upgraded Havoline. Filter some info from Paul Tan
The Caltex Havoline with Deposit Shield engine oil range, which includes the Havoline Fully Synthetic, Havoline Synthetic Blend and Havoline Formula, has been upgraded to API SN, the highest performance standard set by the American Petroleum Institute (API) to date.
According to Caltex, Havoline Synthetic Blend SAE 10W-40 goes beyond what is required of API SN and provides 30% more protection from corrosion and 30% better wear protection. The same oil is also 70% better at wear protection in extreme driving conditions, improving oil stability and increasing durability.
The by-products of combustion and breakdown of oil over time can change the oil viscosity, potentially causing poorer fuel economy. Caltex says that Havoline Synthetic Blend SAE 10W-40 is 55% better at retaining viscosity under harsh conditions.
"Sounds impressive. If lube is SN rated, I think price also goes up liao. Will have to check Caltex station".
AFAIK engine oil API grade got nothing to do with the price le..
