I forgot about chevron. They make a really good Dino and awesome hdeo's.
To be honest if a person is using an API SN rated oil I don't think in real World service I doubt one oil will make an engine last longer than any other oil,when changed at identical intervals. There may be minute differences but over the long term/entire engine service life I doubt that in identical engines and oil changed at identical mileage that any oil will make the engines last longer
Now there may be specific circumstances where one specific oil is required to compensate for some form of defect or environmental issue but for everyday driving they will all work the sale as long as they are changed at a reasonable interval.
