I would agree that the car does not come with synthetic oil.GerryL said:
I agree, having several times in hot conditions deen the temp guage raise above normal in just three months ownership. This engine seems as good a candidate as any when one considers working under difficult conditions.big bear craig said:I have also switched to synthetic. This engine has a big job to do as far as moving the 5000 pound car around which generates a lot of heat. I think synthetic might just add a little extra insurance to the longevity of the power plant. Time will tell.
What have you seen to indicate that Amsoil is better than Mobil 1?gig229 said:Folks,
I have a Firebird with 141,500 miles that runs like new. You know why? I use synthetic oils in my engine (mobil 1), transmission (royal purple trans fluid), and differential (synergyn diff fluid). I also use premium gas (92) too. Many may think I'm wasting my money, but I keep my cars 10+ years and take them 120,000+ miles or more. My cars do not eat or burn any oil and the engine runs as good as the day I bought it. Seriously.
For $19, the dealer is using cheap oil. Do yourself and your Acadia a favor and change the oil yourself (or have someone do it) to full synthentic - Mobil 1 or Amsoil. It's worth it.
By the way, I use Amsoil in my wife's car and change it once per year (I use a longer lasting oil filter). Amsoil is even better than Mobil 1 in my opinion.
