I was buying motor oil today, as my 11 year old car needs a quart added every now and then. I noticed that pretty much every major brand now makes a migh milage formula that they recomend for cars with over 75,000 miles on them, which of course costs a bit more than the regular oil. The all carry claims along the lines of "Restores horsepower" and "Reduces oil consumption."

So what exactly is different about the high milage oil compared to the regular stuff? Does it actually do what the label says it does, and if so, how? Will it do anything for my car, which needless to say has well over 75k miles on it?

The only real difference between regular motor oils and high mileage motor oils is that most high mileage oils contain a seal conditioner additive that is supposed to increase the life of gaskets and piston rings and may help to "fix" small cracks that have already formed. If you change the oil and replace the gaskets as required in the automobile operation manual, you shouldn't have any reason to purchase the higher priced oil.

Most of the claims made about oil superiorness are pure bullshit as long as you are not into racing (and I mean racing, not just an occasional street light showdown).

Just avoid the worst oils (the very cheapest). I have always used Quaker State, which is an excellent, yet reasonably priced oil.
