175,000 miles and still kicking

[guy99]

Off Topic sort of

My 2000 Yukon XL now has 175,000 miles (average speed 41 MPH). It's a Vortec 6000.

How much life do you suppose it has left?

It's not really a tow vehicle since our Airstream is a Classic Motorhome.

It has one lifter that is noisy when its cold.

Lots of them tick when cold, both with more and less miles.
My current truck has a quarter million on it, you should be able to get that.

I'm on my 3rd FT. sell them when they reach 200k. You should be good for at least that much more.

I run mine 300k+. The last was a 1997 F150 with a 4.2l V-6 Currently I am keeping a 1996 PSD rolling along... it is low mileage with only 114k on it Seriously in this day and age as long as you treat it nice, change the oil every 5k there is no reason for 200k+ to be out of reach. You will have to replace various ancillary components as you go, but that is a helluva lot cheaper than a payment on a new one

my 2000 Z71 silverado has a noise when its cold but i just let it idle until warm and not even worry about it. most of the people i know who have higher mileage GM's all have about the same noise or close to it.
i just keep the oil changed every 3k and grease the frontend every service.
because a couple of guys i know with about the same amount of milage on there silverado ether did not grease there frontends or were ever they took them did not do it and they have had problems with alignments and popping noises in there frontends. and most of those parts are pretty expensive if you buy OEM parts. but personally iam shooting for 200-250k on mine.

2001 4x4 suburban with 180k still going strong towing a 73 tradewind 25. at 100k dropped tranny pan and changed filter. changed out u joints for zirk fittings. drive it like you stole it. only issue is autoride disable. still working on that!

I realize that there are differences between the newer 6.0 Liter and the older 7.4 Liter GM V8s, but I wouldn't be overly worried about the number of miles on your Suburban. My '99 K2500 with 7.4 Liter VORTEC has just short of 198,000 miles. The motor has only required two significant repairs -- the timing gear and chain had to be replaced at 190,000 miles and 1,300 miles later the oil pan gasket and rear main bearing seals had to be replaced. The transmission has been trouble-free with regular 30,000 mile interval service. The only issue that keeps recurring on mine is the automatic transfer case electronic control board that likes to fail about every 12,000 to 15,000 miles.

Hey Guy, I wouldn't worry about the mileage, age will get you eventualy; brake lines, gas lines ,etc when you reach about 10 years (at least here on the East Coast) even so all that is repairable, but we usualy sell our at 10 yrs.
If you run dino oil, put in a quart of Marvel next oil change, lifters will go quiet.
I started running syn some time ago in all my trucks. But I had a 97 5.7l that I switched after 100k and that quieted it down...after that I started running syn all the time.

Hey Guy,

I have an '02 1500HD w/ the 6.0. I purchased it new and it has ticked when cold since birth. I've been told that it is piston slap, not lifter noise, that we are hearing. Our mechanic performs maintenance on several fleets of construction vehicles and tells us that the 6.0 is a GREAT motor that will last and last. The "ticking when cold" issue is just a quirk. I would bet that you still have many miles left on your TV.

I ran our '96 Sub to 200,000, and it had no tic. I am a life-long Marvel Mytery Oil user. I put a half quart in the crankcase when I change the oil and I religiously put 12 ounces in with every tank of gas. I don't really know if MMO really works, but I have never been able to wear an engine out.

Auto-Rx is a fine product. Thousands of threads on Bob Is The Oil Guy. I have used it numerous vehicles. Wish I'd been able to use it in some big-motored vehicles I had in the past. It is the one product that will clean the piston rings short of tear-down and then keep it clean.

My diesel is scheduled for some after I send in my latest oil sample for analysis.

As to Marvel Mystery Oil, well, you should look it up also at the above.

My experience is that 175k is well within the service limits of today's vehicles as long as they are serviced regularly. I have two F150's, a 1997 w/301K, 2003 w/129K, and not much maintenance on either other than regular service. Dumb luck or good old American quality...Your guess is as good as mine, but with so many of us on this forum with high mileage rides it seems that Detroit is still doing something correctly.

Keep on Trucking.

The differences:

CAD/CAM production
Electronic engine/trans controls
Unleaded gasoline
Great lubricants
Better tolerances on machined parts

(Plus: radial tires, gas-charged shock absorbers, triple-galvanized sheetmetal, better ergonomics, etc)

Modern engines seem to have an almost infinite life. My brother in law is still using a 95 Ford F350 with a 460 gas engine that I sold him in 1999 with 120,000 on it. He has 323,000 miles on it now - only service done is timing gear, radiators, starters water pums and three transmissions. It's pretty weak now but it still will pull his trailer.
