While our 2007 Honda Accord's oil life monitor (OLM, a.k.a. Maintenance Minder) signals that the motor oil has 0% life left at about 7,500 miles, I wanted to try if I could extend this interval by a factor of two. Mobil 1 Extended Performance motor oil is guaranteed to 15K miles in normal conditions, within one year. This is exactly twice the OCI (oil change interval) that the Accord requests using regular, mineral motor oil.
The oil filter should already be able to handle 15K miles (per Honda it needs to be changed once in 2 oil changes). But I will use a more robust Bosch Distance Plus filter just to be safe.
Accumuilating 15K miles will take me close to a year, Stay tuned for results.
