yes i dnt trust this oil that is y i want to switch to a better brand. but the grade of oil is still a problem for me. 20W-40 or 20W-50?
as u mention i am also not comfortable to use 20W-50 grade in brand new bike but company recommends 20W-50. now i am thinking to try 20W-40, which brand should i go for? orignal Havoline is hard to find market is full of fake 02 nmber havoline.

this question is still un-answered is it ok to change the grade i mean is it safe for engine to switch from 20W-50 to 20W-40. i dnt want to risk any thing about the engine.
