Hello Everyone,
I run Amsoil signature series in my vehicles and the recommendation for my 09 Mercury Mariner V6 recently changed. Previously on Amsoil's website it recommended either their 5W20 or the 0W20. Trying to get the best gas mileage I started running 0W20, but when I went to reorder, they no longer recommend the 0W20 for my vehicle! The only recommended oil is the 5W20 and I am wondering why this would suddenly change? Am I doing damage to my vehicle by running another 10,000 miles on oil that is not recommended? (I'm 5,000 files into my 15,000 oil change)
Any thoughts on what I should do would be appreciated.
Joe
