I have a 03 Escape. The Ford dealership just told me I need to follow the recommended oil (motorcraft 5w-20) or it would void the warranty. I don't prefer to use this as it is a synthetic blend and not 100% synthetic. I have read some of information regarding this. Most notably the Magnuson - Moss Act. It states that a manufacturer may not require a specific brand or type of aftermarket product unless it is provided free of charge. If your dealership continues to tell you that you must use 5W-20 motor oil and or/ a specific brand of 5W-20 motor oil, then ask them to put it in writing. Their position is inaccurate, and, in fact violates existing law.*
Has anyone else had troubles with Ford doing this type of business? And is anyone using amsoil 5w-20? I used mobil one in my 01 mustang. And had no problems with it.
Thanks, Greg
