So who's go the highest mileage on a LS engine ? Anyone brake the 500,000 ?

Just changed the oil in my dads company truck today, 01 GMC Yukon XL LM7-5.3L

That would be impressive, I have had this engine out of the truck once. The oil pump started to go a 219,xxx miles. The cam bearings weren't in good shape when I started to look into things. So a new oil pump and cam bearing went in this engine, everything else was reused from the factory.

Local AMSOIL dealer has a 4.8 express van with 800k on it.

Wow, and I was worried I hit 200k on my Silverado this week.

My previous truck, 2000 Silverado 4.8L, had 315,000 when I sold it. It was all original other than an alternator, power steering lines, a wheel bearing, and a waterpump. It had about an encyclopedia of maintainence/oil change receipts too!

Current truck, 2002 1500HD 6.0L, has about 190000, and should have no problem making that too.

Thats just getting broke in

Nice, These things do seem to last forever when they are maintained properly.

315,000 on my 2000 Silverado 5.3. Two water pumps, two alternators - those are the only things changed on the motor. 10-40 High Mileage oil, doesn't burn much. I would say it's still going strong but it's actually sitting in my yard waiting for me to install my new trans. Which lasted 315,000 miles.

I've seen some local cab overs close to 600k original engine and trans. & still running like new

if you think that 359,758 number on the odometer is impressive...
- calculate the amount of gallons of gasoline it took to get there,
- and calculate the amount of money spent for that gasoline over the last 15 years

Nice work


You made for easy math with this mileage...

Truck gets 360 miles to 27 gal tank. 360,000 / 360 = 1,000. 1,000 X 27 = 27,000. Gas here is $2.34 so lets just go $2.00 for a 15 year average. 27,000 X 2 = 54,000

27,000 gallons burned
54,000 dollars


Some one check my math

I've heard some very good things about LS motors when pulled a apart. Some claims on 300K miles motors they can still see the factory honing marks on the cylinder walls.

When I opened this motor up at 219,xxx miles for the oil pump the cylinders still had very nice hone crosshatch in them.

It makes sense. These things couldn't last hundreds of thousands of miles without burning a bunch of oil if the walls and rings weren't staying fairly intact. I think they lack low end torque in truck applications, but they certainly make decent HP and last for damn near ever if taken care of. GM nailed it with these things, thank G.
