Bro, to choose the type of engine oil is always confusing. Some people said no need use synthetic. Some said synthetic is the best.
But for me, i will always treat my car with synthetic. So far, never experienced any damage to my engine. To choose brands of oil sometimes can be confusing. My advise, just stick with established (company) brand name and follow strictly to manufacturer recommended viscosity. You wont go wrong, trust me.
Herewith, I would like to share a write-up on engine oil from one of the expert (he is a dealer actually) in UK.
