My E-350 has 240,000 and my Chrysler Aspen has 250,000. We will drive them till they can no longer go.
Which will probably be for another couple of years the way they are hanging together.
You're my hero.
The drive trains were still fine, getting 2 to 4 MPG better than the factory specs.
I used Amsoil 100% synthetic oil, made in the USA in all of them, the engine oil changed at 25,000 mile intervals.
I saw an ES300 with 562k miles in it. Original engine too I believe.
