+1, my oil changes cost less than $30 and i still have enough left over for the lawnmower

 

Uhhhh... the MM monitors and calculates all the different variances of the car and makes the best recommendations based on the data it collects. Way better than human guesswork.

 

In other words, your car is smarter than you are. Don't feel bad, it's smarter than most people. Have you seen the internet?

 

In terms of being able to monitor the internal operating conditions of the engine, yes my car's computer is smarter than me (and you)... since I don't own several thousand $ of diagnostic equipment.

With my Chevy truck, I know to change the oil around 5k miles, air filter when it's dirty, plugs & wires when it runs rough, trans fluid when it starts shifting hard, brakes when they squeal, tires when they're bald, belts when they start cracking, etc...

 

But not better than oil changes with Mobil1 exactly 5,000 miles after the last one.

Do you always reply twice to the same post?

BTW, OBD2 scan tools are very cheap these days, and your human critical thinking and reasoning skills are free - no need to spend thousands

 

Wasn't the same post, it was in reply to your omment.

And SURE, OBD2 scanners are cheap... but that's not what the MM does. In order to find an issue, even with the MM you'd still need the scannner.

And you can put new Mobil1 in every 100 miles if you want to, but it's a waste of money... just like changing it every 5k, if it doesn't need it. If the oil is still good until 8k, then why waste the $. You're talking about throwing several hundred dollars out the window over the course of a few years, just so you feel good. So while you waste your money on your "free" human critical thinking and reasoning skills, I'll be saving that money by following the MM.

 

Basically what you're saying is I'm not wrong, we just approach the same problem differently. Fair enough!

cheers,
