793 miles into the OCI, the Change Oil light came on. I checked the owners manual and to my surprise, the light comes on by determining the condition of the oil instead of by the mileage.
Car is currently on 4 qts of Havoline dino and .5 qt of PP. Well really a total of 4.5qts. I'll explain: these cars normally take a total of 5 qts. This one however only took 4.5qts to get the dipstick to full. I'm assuming because there's about an equivalent of .5 qts of sludge laying around inside and on the oil pan.
How accurate can this determination be? Especially from a '95 vehicle. Maybe I have Blackstone Labs at my finger tips haha.
