2010 silverado 260000 miles

[Mit12]

I have a 2010 Silverado 1500 with a 5.3 that has 260,000 miles on it. It only uses 1 quart of oil in 6000 miles. My question is how long can the injectors go and what would be the symptoms of them needing to be replaced?

There is no specific life time for any component in an engine. I would keep doing exactly what you are doing. Whatever it is, it's working.

I guess I don't see the correlation with fuel injectors and oil consumption, but 1 qt every 6K miles doesn't seem terribly for that mileage.

Given that many manufactures now a days say that 1 quart every 1000 miles is acceptable- I think you're doing pretty good.  The injectors are doing well, but who knows when they will start to give out.  Some go at 70,000 miles, some may go a million miles.  Put some $$$ away each pay check you get dedicated to your vehicle be it repairs or a replacement vehicle someday.

Guys have been telling me they've done injectors on '17-'19 trucks with less than 7k on the clock, so consider yourself lucky. They do fail regularly on the '07-up trucks, and usually will cause rich codes, rough idle, and hard starting. At that mileage, you could be on the 2nd - 4th set.

 

On a modern vehicle, injectors would be the last thing on my mind at that mileage. For starters, you're probably 60% through its 2nd replacement engine & transmission, and the rear differential should be close. The front end, if you live in the Northeast, has probably been overhauled 4 times (or much more) so far. Not to mention all the electrical gremlins that usually pop up much, much sooner, especially if you live in the rust belt.

If that's actually the OE engine, you'd better play the lottery!

That is the original engine only thing I have done is 2 sets of spark plugs, 1 set of plug wires and oil and filter changes.

Yours is the very first 5.3 in a 900 series that I've ever heard of making it even remotely close to that far, without major valve train repairs.

 

You bought it new?

It was my work truck and when I retired they gave it to me. The truck looks and drives like the day it rolled ohh the lot.

Nice! You got one of the few good ones.
