I'd say no...I bought my VX new (only owner) and she's been on synthetic (Mobil 1) since I did the first oil change @ 3,000 miles. Now have 86,400 miles, and everytime its due for oil change...dipstick only shows a deficit of like 1/4th of the total length between full & add (or less).
I refer to that amount as 1/4 quart as I believe you're down 1 quart if you are @ the add line.
