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.

easy p-cheesy

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.
