Hello, I own a 1994 Ford Econoline E150 Luxury conversion van with the 4.9 Liter Inline Six cylinder engine and the 3 speed automatic with 74,000 miles. The Ford label under the hood says the oil capacity is 5 and a half quarts. I had a oil change yesterday. The mechanic put in 6 quarts, overfilling it by a half quart of oil. I confirmed this by waiting a few hours and then checking the oil level when the engine was cold. I have heard that putting in too much oil causes too high oil pressure which causes engine oil leaks and "astronical prices" to fix the front and rear engine seals. I was just curious if anyone else has encountered this overfill problem, and whether it makes sense to take it back to the shop and have them drain the 1/2 quart of oil out of the engine. - Billl
