In any case, my mechanic, whom I trust greatly, said that he gets A LOT of cars brought in with engine damage due to the wrong viscosity/weight oil used.
How would he be able to link wrong viscosity with engine failures??? he can't.
So this mechanic can tell the damage on an engine when using 5/30, 0/20 or 10/30 instead of 5/20???

there is absolutely nothing wrong with using 5/30, 10/30 or 0/20 or 0/30 in the 3.0 liter duratec engine for the Escape or any other car...
That's an old wives tale and simply not truthful. About as real as mechanics saying that you should only use the exact viscosity and the same oil manufacturer and stay with it for the life of the car. Too funny.
I usually use 5/20 MC because I can get it by the 5 quart jug now at the dealer and it's still cheap. I have used mobil 1 5/30 for half the 60,000 mile life of the car so far though.
