297k on a 2003 Yukon... 9k hours on run time

 

At 80k miles, My 2000 Silverado was burning 2 quarts of oil every 2k miles... Switched to Valvoline High milage 10-30 and hasn't used a drop of oil since... used a little on first oil change but by the second one it stopped. No oil leaks either almost 140K now. Noisey as hell when it sits or its really cold...

Damn Piston slap on these early ones... Still has around 60 PSI on start up and never drops below 40 PSI in the hotest conditons. Gas milage sucks could probally use a set of 02 sensors and I bet the piston rings arent in the greatest shape from it running hot and low oil...

changed
1 set of plug wires
2 sets of spark plugs
1 water pump. Turned out to be bad gaskets but already had the pump so I changed it out any way.
1 Fuel Pump
2 Main belts
1 Ac belt
1 set of rotors and pads all 4 corners
3 sets of tires
1 set of rims
1 Drive shaft bearing on the 2 peice drive shaft.
1 trans not because it went out but because it felt week esspecially after long drives and I wanted to maintain reliablity. Also didn't have a cooler on it.
1 center jump seat/arm rest cover... The lids always go bad...
Service fluids regularly or as needed if sooner

 

My buddys truck with a 5.3 has 275k miles and still loves the 150 shot. His 4.8 truck had 285k miles and was taking a 250 shot like a champ.

 

My '03 with 90k on it doesn't run "like new" anymore... I think it might have something to do with the air compressor kb racing sent me though

 

4.8, but I just passed 200,000 miles, and no engine or transmission trouble until a couple weeks ago. The engine did not use a drop of oil between oil changes (every 3,000 miles). NOW, however, I have all of a sudden smoke pouring out of the tail pipe at start up, and oil consumption like crazy.

 

99 5.3 with 279k , runs like a top.

 

How about had?... I used to have a 03 avalanche with 325k :0 i sold it a few years ago and when i ran in to the buyer i asked about her and he mentioned he was close to the 400k....

 

My old 1500 had 187k when it was totaled. Current truck has a little over 166k now and ran a best of 10.17 in the 1/8 in 4WD

Oil pressure is almost always right at 60psi sometimes gets as low as 45-50 depending on the day. Uses maybe a quart every 6k with Amsoil 5w-30.

 

379k on a 07 just traded it in. Bought it new

 

I have a buddy who sold his 03' Yukon at 285,XXX and another one who has an early 00's RCSB with 23X,XXX on it, stalled w/ factory 4L60 and still sprays it from time to time on a 100 shot. My '05 only has 48,135 on it.
