Today i drained my 4 months old oil with 6k miles on it and usually it comes out brown and dark but this time it was still translucent with a nice amber color. I've seen 3k miles oil way worse than that. What has changed during this OCI and possible reasons:
- 75% highway, 25% country roads, no short trips or stop and go at all.
- Hypermiling and driving slower than usual on the highway, very light throttle input.
- Only used E85 over the OCI. Not even half a tank of unleaded this time.
- Shell Helix Ultra 5W40, low Noack, GTL.
- 2x half a quart of oil added during the OCI.
- Lots of italian tune ups + many short OCIs with various oils prior to this 6k OCI and the one before, possible cleaning action.
What do you think is the main reason? I am really impressed. I am too lazy to go dip something in the used oil and take a pic now cause i am in bed but maybe tomorrow.
