Burt oil

This is 2002 caravan 3.3 I notice since I bought it more than a year ago that the oil get really burnt even 3 o 4 weeks after the change. Could you give me some tips. I change the oil myself regularly every 3k.



Thanks!

What year is it,
how many miles does it have on it,
do you know anything about its history,
and how are you determining that the oil is “burnt”?

year 2002 120k on it… It gets too dark so quickly… In the other car it doesn’t get so dark so fast. Thanks

It could just be wear in the cylinders allowing more blowby. A compression test should give you a good idea.

Older cars will get their oil dark pretty quickly. How many miles between adding a quart?
