I've been running AmsOil in near everything I've owned for the last almost 20yrs. The more I hear about how picky manufacturers are with their fluids in their new cars has started to make me think twice about AmsOil lately. This thread don't help, makes me suspicious of how the fluid is treating the Aisin trans. I've got to do my first oil change on my Cruze and not even sure which brand of engine oil to go with anymore. Although, when I called the Chevy dealer, to buy the oil they use seems to be cheaper than if I were to go to the local parts store(with my discount). I'm thinking factory fluids is best anymore...I dunno.
