so what have you seen out there... recently purchase a 5.4 2002 f250 and just curious on its life span. it has 34,600+ on it right now!

 

There was one on here awhile back that had about 370,000 miles on it!!

 

holy crap!

 

most will go 250k easy. there are a few members here with engines in the high 200's

 

I believe someone posted around here as having 409k on a 5.4 in a van, 90% highway miles...

 

2005 E-250 van 11,500 miles 4.6, got towed away this morning with a DEATH noise in the engine, this is used for a/c service, city mile been using 5-20!

 

My dad's E-250 Extended Turtle Top Limo Van has about 150k and still going strong. Although it uses some oil(Mobil 1 10w30) between changes. Its very reliable and he runs it pretty hard sometimes.

 

Our one truck at work is a 1997 F-250 Light Duty with the 5.4 engine. It just turned 200,000 this week. Still idles and runs like it was brand new.

 

My 97 has 183+ and still runs like new. No engine problems at all, just regular maitanance.

 

My 97 Expedition XLT work truck just turned 500,000 kms (310,685 miles).
The only babying it gets is full synthetic oil changes (Castrol)...... my
workhorse just needs "water". It's a 4.6L.

My 98 F150 4.6L extended cab with a 8ft box has 282,000 Kil. 175,000miles. Knock on wood. Oil changes every 3 to 4 thousand K and Tranny changes 50,000 K. the drivers door is rusting out on the bottom and it has the good old pistonslap for about 5 minutes on cold start ups.

 

175,000 miles. See, I knew that there was no need to worry about the piston slap, it is annoying, but doesn't hurt anything, just proves that the piston skirts were a little short allowing the pistons to slightly wobble in the cylinders until they heat up and expand.

 

wow, my 97 I just bought has 62,000 on it.

 

163,000 on a gutless1997 4.6 ... timing chain just slippe dand ruined the motor.

 

my 02 has 100,000 and she feels brandy new
