Black Sunshine 07

i know with new modular motors they last much much longer than the old style of engines but does anyone know about how many miles the 4.6 3v can rack up before it starts turning belly up? and then what to expect with a rebuild?

This is going to be a tuff question since these motors are new. I am sure the 05 owners are not going to have to much more than 50k miles tops (this is alot!!) Kind of a pointless question IMO

not at all....

i have been wondering this for a while too now. because this is my first car, i really want to keep it around for awhile.

50,000 miles???! ARe you kidding?
I drive 1,000 miles a week for my work in my 07 stang. I fully expect it to last the 130,000 or so I need til I trade. It will stay stock and I use Mobil 1. I generally stay off the pedal. Do you think I'm dreaming?

as long as you maintain it and don't abuse it a long time..

i think these motors will last forever if you take care of them, regular oil changes, stay off the limiter, obvious maintenence, etc.

Well according to the service manual, 150,000 miles! They have schedules for all the service needed up to that point!
Of course, given the mods we see here, your mileage may vary! And given the way some Mustangs were getting in no-fault accidents they may make it to the junkyard before getting that many miles!

I think my engine lifespan is not measured by miles but by hours of use lol.

Actually, and according to 5.0Mustang&SuperFords magazine the weak link in the old 5.0s are the block itself, the rotating assemblyis fine, on the other hand, the 4.6's weakness is the rods and pistons not the block.

I did not say they would last 50k miles, what I meant is if you did an average of the GT with miles on it the higher end number would b 50k miles. 25k a year most people who owned a 05 have only owned it 2 years or so.


Now the reason this is pointless, is because NO can say for sure since not many or if anyone even has 100K miles on it. I am sure they will last as long as you take care of it. But the question is pointless and premature since the cars are only on its third year of being made.

Think abou it how can anyone answer this question with out having cars with 100k miles on it to compare. TO early to tell.
