My 2011 Taurus V6 has 143,000 on the spark plugs-- I drive easy-can it go further?.
I am getting 35.5 MPG at 68 MPH. Great car
Not mine but pic shows it can go for a time but bad things happen. Too large gap hurts the coil/coilpack. 100K is about the end of the platinum. After that the gap opens up more quickly.Was in the upull the other day getting parts for the 98 "black turd".
On a whim, i found a random 3.0 and pulled what looked like the original
plug. There was almost NO center electrode left! yet it lived its life until
it was junked. probabaly did not run top notch, but it made it to the bone yard
