When Mobil 1 first came out, around 1980, I put it in a new car that I had.  
It boosted my gas mileage about 15% immediately.  However about 12,000 miles 
later my camshaft went.  I remember the Mobil 1 advertising was that the oil 
was good for 25,000 miles.  The dealer told me that the oil was OK but I 
still had to change it every 3,000 miles and the camshaft went because the 
oil wasn't changed frequently enough.  I didn't believe them entirely but 
there might be some small amount of truth to it.
