Well said dude. A lot of it is due marketing and etc. Recently had some full synthetic oil from a reputable company to try out. Didnt feel anything different compared to the cheapo mineral oil I have been using for the past one year. Engine performance and fuel consumption remain similar. Yes, there are some websites that claimed better engine performance and fuel consumption with synthetic oil which I find it hard to believe. And now, most mineral oils are actually synthetic in some ways (its molecular structure is modified...Castrol GTX especially)....try reading how engine oil is made.
