You are probably not going to get many responses here on this
1) there is a seperate forum on this site exclusively for oil & changes
2) most (not all) fly off the handle ,get a hernia, & their head explodes any time a oil question is brought up ( I am not in any of those categories listed)
My suggestion is to go to the oil & lube forum ( just scroll down at the index of forums and you will find it). Then search the threads- or even use the search option at the top. There is a lot of good and valuable info from some very sharp cookies here.
The old saying "you get what you pay for" rarely is accurate any more. BUT if you dont pay for it - the is no chance you are going to get it-- IF you pay for it , at least there is a chance you will get it. Keep this in mind with the oil for one
