Heres the backstory I bought an 06 is350 2 years ago and the PO told us that the vehicle sat for a year since they never used it much. So I monitered the oil for the car (99k when bought 126k right now), and the first 3 or 4 oil changes the oil was at or near the bottom level on the dipstick and I checked it after night so I know its correct since 8+ hours of not moving.
I did use PUP 5w30 for the first two or three 5k oci which came out very dark but I personally dont think the pup caused it to stop burning oil.
I did run the car hard for the first few months and still do now but not as much as before. Could it be possible that a stuck ring was unseized from the aggressive driving?? I used the manual mode on it sometimes and it causes for the car to stick up in high rpms if you dont shift early. But normally I now drive the car right around 2100 where it shifts smoothly and I put it under less stress too.
Anyways at the end of my 5k oci before I had to almost add oil and one time I did because it was below the bottom hashmark, but now I am at 4k out of 5k on my interval and it hasnt dropped oil on the dipstick since it got changed and im honestly bewildered and astonished yet also happy.
Yes I changed it at walmart this last time and sticker says every 3k for their oil but thats a waste, since you can see my mileage is over their requirement.
