Hooks Lincoln

My 2006 MARK LT Lincoln Truck ran out of oil with no warning,period ! until it was to late.Service Manager said the truck was'nt designed that way (his words). Even though the (check engine ) dash comp warning,period ! until it was to late.Service Manager said the truck was'nt designed that way (his words). Even though the (check engine ) dash computer told me every day every thing is OK ! Tap the button all it every said is engine OK- temperature OK- oil pressure OK. I should have went by the oil change sticker, (his words )you can't trust the computer ! I thought all vehicles, (dumb me !)had a mechanism like cars from the 50s-60s-70s-80s and so on had a oil light come on that said CHECK OIL, and the temperature gauge needle would show if you had low oil pressure ! NOT this 50,000 dollar SMART truck (there term ) its not designed that way.Then the computer is there for SHOW,very{ deceptive} I don't mind taking responsibility for not changing my oil when i should,but i never dreamed it would run out of oil with no warning,here in the 21st century ! Whats so hard about a oil (low) warning light,we've had it in all the older cars and trucks since the Fifties. I think HOOKS or FORD should have met me half way on the monies If i knew the computer didn't work i would have check the damn oil! P.S of course if the Dealer-ship would have told me all this up front (THEY) would not be receiving over 8,000.00 dollars would they ? More
