#3. Tune ups. Do you know what a tune up is? Changing spark plugs, adjusting the carburator, checking the timing. Things that car technology made obsolete today.
Are you
really suggesting that technology has made changing spark plugs and checking the timing (basic preventative maintenance done on all cars) unnecessary? It's true that the computer monitors a lot of parameters and will trip a MIL if necessary, but basic prevantative maintenance is never a bad thing.
#2. Winterize is switching to a thinner oil that won't thicken as much, chaning the anti-freeze etc... Again not needed.
Not necessarily true, especially if living in extremely cold climates, such as Minnesota. Indeed, several manufacturers recommend switching to a different weight oil if the car will be operated in extremely cold climates.
The bottom line is, follow the recommendations of the manufacturer; not what a bunch of guys on a message board about shredded glutes say. Unless you're like Bay and think the manufacturer is in cahoots with oil companies and shady gas station attendants, and you can just run your car on home-made moonshine, like the kind your grandpappy made in his terlet.
