Oil Changes - Step in

[xlr8nflorida]

How many of you change the oil regardless of mileage and do it because of time period??

Reason I ask is Mobil 1 says 6 months for regular/high mileage and 1 year for extended Mobil. But what if you just start it up 1 or 2 a month, let it run for an hour and take it for some short runs. Seems kind of silly to drain it when it has a few hundred miles on it if that. Also, do you feel it makes it difference if you are up north (bad winters condensation etc) as opposed to down south.

I change mine every 6 months - cost me $60. I'm sure its overkill and pouring $ down the drain.

I know some car owners say moisture, contamination etc but if you warm the car up fully say 45-60 minutes. All the moisture would be burned off as steam no? Others don't like to start cars at all in storage.

Not really looking for debate, just curious as to what others do and why they do it.

Mobil 1 always looks dirty, its the way it is. I think its because all the "stuff" is suspended in the oil- that is why the internals of the engine stay immaculate.

not sure if that would be good for Z. I would think it wouldn't have the additive package since most racing oils are drained after a race. Also in the past, I have heard not sure if that would be good for Z. I would think it wouldn't have the additive package since most racing oils are drained after a race. Also in the past, I have heard Joe Gibbs oil is excellent and of course we have the Amsoil cult people

Oil filters - most people running the Bosch 3401?
