Yes, REALLY! He's saying he could've went to 100k easily, and I agree, however, I'll buy the NGKs and do it myself, so who knows when I'll change em, won't be before the 60k mile warranty is up, that is for sure... Don't get me started on preventative maintenance...You've got fools around here changing ATF at 15k miles, and every 15-30k thereafter...Comical. I'll run mine until I trade it in at 100k most likely, not a worry in sight...Really? Preventative maintenance is considered a waste of money? Do you notice a change when changing the oil, air filter, diff fluid, coolant, etc.? No of course not.
If you do preventative maintenance and notice a performance difference, it means you went beyond the point that, that component or fluid was intended to last. Meaning you were running sub-optimally prior to the maintenance being completed.
Alfa calls for 30k mile intervals on my the 2.0T Giulia.
I have a car I change the spark plugs on at every oil change. Granted, it puts out almost 300hp p/liter to the wheels, and yes, you can damn sure tell when you don't... Cost me less than $8...lol
