Got 137000 on my 97 Expy with the 5.4. The Da*n thing runs just as strong as a new one! I love it! Getting about 17/19 MPG and no problems. Oil is changed every 3000 miles with 5W30 Castrol non synthetic,just had to put front shocks on it, but it only ran about $35 for Monroe gas matics. Tow a trailer for side business remodeling houses. What more can I say, The thing is awesome!
