No. he is not giving advice, rather promoting specific imported brands and condemning local products with out specific knowledge. Most importantly, he is suggesting drain intervals on whim.
Agreed, that this is the purpose of the forum but one should advise others if one has specific knowledge as you may lead to loss of asset.
As regards to my last statement, its generalized comment about so called gurus on PW.
Am studying oils indeed and try to spread the awareness among many gentlemen. Here majority of us have mind set of havoline or zic hiflo without knowing the actual functioning or latest characteristics or what their engine needs infact. Majority of our brothers just put the manual aside and start pouring havoline 20/50 or zic 20/50 in new cars. My brother runs oil shop and we have many examples everyday. Sometimes it feels easy to move the mountain rather than convincing someone to feed better oil to his car.
Yesterday a gentleman came with Alto 2008/09 model and was using zic hiflow & havoline since day one. We suggested him to use SIM3 which is semi synthetic oil, have same viscosity as others, has more latest grade than others, has more longer change interval than others, and has better properties/characteristics etc.etc. We gave him 15 min. lecture and after that he said plz pour havoline this time and I will try something else next time. And we know next time he will go to some other place for oil change.
Moral: You try to give right advice to the people and people start thinking -ve about you.
Hope you get the point.
