Has anyone submitted an ATF sample for lab testing after 50,000 or 100,000 miles? Wouldn't you think that would be more reasonable (and cheaper) than paying some rip off artist to change fluids just so he can make an extra $100 off you? Come on folks, where is the evidence this practice makes sense? Do you also change the air in your tires every 10K miles? If the manufacturer doesn't recommend it WTF are you doing it for?
I'm thinking this is just a dealer/garage scam to jack up maintenance fees. I can understand for a vehicle doing heavy towing but the CX9 has a wimpy towing rating so that is not a likely scenario with our cars.
Where is the freaking evidence that this practice makes sense. Please do not quote evidence from Jiffy Lube or your local garage. What do the engineers say and what data do they provide to back it up?
