I have an 02 suburban with the 5.3 that has ~220k miles on it.
I've owned it for 5 or 6 years and always do regular maintenance. No idea what previous owner did concerning oil changes but there is definitely some sludge.
I used a product like Motor Flush, or some such, out of curiosity about 18 months ago. Ever since then, my oil gets dirty much faster. I thought this would be temporary as things get "flushed" out in a change or 2.
However, since using the product as directed, I have been changing the oil every 700-1k miles. I am at like 6? oil changes now totaling maybe 5k -6k miles.
Before I get blasted for being excessive or paranoid, be aware that lifter tick at start up happens after 500 - 1k miles now on the oil. An oil change fixes this.
The oil drain plug also has sludge all over it when changing the oil. And the oil gets dark....fast. Never used to be like this.
Good grief! how much longer can this possibly go on? Lol.
Anyway, just an observation/cautionary tale
