07+ E has maintenance minder. I had always let it made decision for me on my wife's 07 CR-V. Honda recommended replace engine oil when maintenance minder reach 15% engine oil life. CR-V come out to be ~9k miles when it reach 15% of oil life. I will let maintenance minder determine for me also for my E. I am at 50% for my E, but only drive ~3k miles. I have a feeling my E will need to change oil more often.
Just got my 07-09 E service manual, here is from E service manual how 07+ E maintenance minder determine oil life & when need service:
"....Based on engine and transmission operation conditions and accumulated engine revolutions, the Element's onboard computer (ECM/PCM) calculates the remaining engine oil and automatic transmission fluid life. The system also display the remaining engine oil life along with the code(s) for the scheduled maintenance items needing service"
I like accumulated engine revolutions is also part of formula for engine oil life.
It does also mention engine oil should be change at least every 12 months, regarding mileage.
