My '70 Boss 302 Mustang holds 7 quarts as well, so I'm not harboring the notion that a rogue engineer in Dearborn figured one extra quart per oil change would give a boost to his Exxon Mobil stock. Maybe I should have phrased that statement "Does anyone else think it's ridiculous........" Perhaps they figure that, with a suggested oil change interval of 7500 miles, it's a cheap bit of insurance once there are lots of Fusions on the road with 150k miles and leaky rear main seals.
