Anti Freeze

What mileage should it be changed at. I was at dealer today looking at the 2011's & salesman said it would help fuel mileage a little to change out the antifreeze. Said it cools the EGR valve & the fuel. Dont know if this is true or not. Said when antifreeze gets dirty to change it out. Looked at mine in overflow & its definately dirty. I have 33,500 miles on my 2009. Is this BS or the truth...

Your coolant isn't due for service for some time yet, I think it might be 5 years 150,000 kms or more. Changing it isn't going to help your fuel mileage at all.

Salesman is an idiot. Antifreeze does not lose the ability to cool with mileage. It needs changed because it chemically breaks down and loses the ability to manage corrosion. Change it every 60k, and if you're serious about 2011's make sure to buy from another salesman and let the other guy know he didn't get the sale because you know he is an idiot. (Gotta do something to keep them in check)
