so, my van DRINKS oil.. 1 qt every other fill up... i keep adding oil

do you think it is necessary to do a full oil change on it? or just put a new filter on it and top it off...

the weird part is that i see no leaks wherever i park, at home or work, and it does not have blue smoke.

I would still change it every once and a while, maybe every 5000 miles. But I'm a maintenance freak.

My truck leaks like a sieve, change the filter every 6 months.

How many miles total is that for you with every other fill-up?

Haha, believe me. It'* a Chrysler 2.5, they burn oil, even though you can't see it or smell it, but it does. My mom'* '84 Lebaron had oil disappearing all the time, no leaks anywhere, so it had to be burning it.

How does the coolant look?

everything looks fine. the oil cap does have a milky substance on it, but the oil on the dipstick is fine. i get about 200 miles to a tank, i think.. there is no trip meter

Thats just condensation right? Nothing bad, right?

My oil used to disappear fairly quickly also (at Mobil1 prices ) So now I put in cheaper, thicker synthetic blend and I lose a fraction of the oil.

I'd still change it. Muck can still build.
