Just wondering how long ruffly there good for? thanks

Mine will roll over to 80 k this week with not a hiccup

I'm pushing 119,000 mi.:-X22 Left a pair of 50' black strips in the road Thursday, just because. And I took pictures!:-X03

I'm at 236,453 miles in my 97 light duty F250(5.4) and still going strong.

60,000 trouble free miles right now.

77000 and needs a head gasket. :mad:

It was such a good engine until this.

All coils have been replaced (not all at the same time), replaces o2 sensors, egr, upper control arms, lower ball joints, front calipers....just the normal stuff. Engine still runs strong.

63K on a '03 SD. Runs like a top (knock on wood)

Oh and LOTS of oil changes.
