I live in Ga. My car has 78,000 miles on it. Recently the Vcm has been more noticeable kicking in and out. I have Also been burning more oil. I was using Motorcraft synblend 5w-20 motor oil.
Recently it was recommended to try Mobile 1, 0w-40 European Formula engine oil.
I have just done a 500 mile road trip with the Mobile 1. The VCM seems much more consistent and the engine is smooth and quiet and mpg is unchanged.
I like the way it runs. Am I making a mistake with this oil in my car?
Thanks in advance.
