I recently changed oil on my 11 Buick Regal and noticed that Dexos1 was the recommended product to use. Partnerships in the US are limited to full synthetic higher end brands such as Mobil1 and Pennzoil. GM's publication on the use of Dexos claims to offer advantages in fuel efficiency, emissions longevity, and oil change intervals. Is it malarkey or another scientifically proven breakthrough component in motor oil? Just curious to see what members think? A 'do-it-yourself" $50 oil change on a naturally aspirated 4 cylinder powerplant seems excessive...
