ok question i bought my car used...well when i drove it off the lot i didnt pay any attention to the digital settings....well the next day i was playing with them and i noticed the oil things said less then 100%...now im thinking "why is this not at 100 when i just purchased the car and everything should have been checked, changed, cleaned, etc"...well i took it back to the dealership and asked them why was the gage reading less then 100 and it was suppose to have been a fresh oil change the day before...well he did the 3 pump thing and the gage reset...now my question is.....does the gage detect what the actual oil level is when reset or does it automatically reset to 100% irregardless of what level the oil is actually on? (did that make sense?)
