2009 Chrysler T&C, 3.8 engine. Vehicle was consuming oil at the rate of 1 quart per 1000 miles. Last OCI, I used Mobil 1 Synthetic HM. Consumption was 1 quart in 2000 miles. I topped off with Mobil Super HM. 3000 miles later, I was down about a quart. Again, I topped off with Mobil Super HM. About 700 miles later, I dumped the oil because I had left my oil cap off.
This OCI, I just used Mobil Super HM. Oil is down a half quart in 1000 miles. It has me wondering what is cutting the consumption, the "high mileage" or the "synthetic" portion of the oil. Previous oil changes with Mobil 1 and Pennz Platinum did not cutbconsumption.
When I am down a quart, I will top off with Mobil Super HM and see if the vehicle "adjusts" to this oil.
After that, I will reverse the oil change pattern and observe. Previous OCI was Mobil1 Synthetic HM with Mobil Super HM used to top off. This OCI will be Mobil Super HM with Mobil 1 Synthetic HM as top off. It just worked out this was because I didnt have Mobil 1 HM when I changed oil last.
