Oil Change Interval Question.
Mechanic says I need to change my oil every 5000km, I never have (do my own oil changes).
Always do 8,000km.
Oil I buy says good for 12,000km
My car's owners manual says I can go 15,000km.
My car does not burn any oil, and I'm coming near my interval, and oil quality still looks good.
I drive over 1000km a week.
I also change my oil filter every oil change, however the Mobil1 filter I use says its good for 24,000km. Is it okay to start changing my filter every other oil change?
I use synthetic 5w30
Car is a 2001 A6.
All this taken into account? Which oil change interval should I be following, after 8000km, my oil dipstick still shows oil at the full mark as well.
