U think using Petron 20-50 in Gli Auto 1.6 is more beneficial than using other engine oil? Indus claim that Petron 20-50W runs do mileage of 5000km which i heared from oil dealer as false claim.
I cannot understand why 20w50 oil is being recommended for a brand new engine..My uncle has a gli 1.3 and i was not able to convince him that petron 20w50 is not a reliable oil + this viscosity is never recommended as standard from car manufacturers
