I bought a TC [see left panel] new. Oil change interval is 7500 miles [you got to be kidding!]
A Ford mechanic once said to me, if you want that engine to last, change oil at 3000 miles. I need the TC to last to 500,000 miles!
At one point in the literature Ford says the TC can last up to 150,000 miles [at 7500 mile oil change] What do you think the engine is good for if the oil change is at 3000 miles?
Now if one gets a car and will dump it at 100,000 miles, alright go with recommended oil change interval
