do you have to change the oil if u do the atf cause i just changed it less then 400 miles ago. how long before i have to change it.

 

No, the ATF shouldn't affect it. You should do it about every 2000 miles, so you have 1600 to go.

 

should you take the aging of oil into account? I don't put many miles onto the car, so how often should you change it, going by age wise?

 

I heard that some of the atf will get into the oil and you should change it. I dont remember where I saw it but do a search and you should get about a million hits on it.

 

ATF will leak past the seals, on a motor that has low compression.

But how expensive is oil to change??? $10???

Maybe $15??? whats that cost...maybe 3/4 of a tank of gas???

I'd pay $15 to make sure it is clean.
