Sometimes the young employees gets the milage wrong or he's doing it on purpose. I thought full synthetic oil was 5,000 miles before your next oil change?

That 3,000 mile oil change is both a myth and true. Modern oils can last 5,000 (I put 20,000 in my 2012 F150 w/V8 engine)
It does depend on how hard you drive it, if you flooring it off the line, that will cause it break down faster, use a standard filter instead of the higher dollar filter? the oil will break down faster.
I routinely use 20,000 oil with a matching Fram oil filter good for 20,000 plus Fram air filter.
The reason all the vendors want you to change oil every 3 k miles is because it adds $$$ the seller & oil companies.
Oils have gotten better since I started driving back in 1981 - then you did it every 10k miles.
I change the oil at 15,0000 and on the air filter since its a waffle style I blow it out with an air hose 1 time.
Do start keeping a notebook on these things. My late father kept 3 ring binders on every vehicle he owned starting with mileage on it when he drove it off the lot. He even jotted down mileage on it if he put it in the shop for work for comparison.
But track oil / air filter changes with mileage between them & date done.
Any maintenance done to it track when and what.
