This is off a friends 2007 Civic with 365k miles. The engine has never been opened up for any reason. The OCI was determined by the OLM and was done at 9k plus miles.
Oil changes have always been done at the dealer using Valvoline non synthetic bulk oil and a Honda filter at intervals ranging from 6k miles to 10k miles. The OLM has always been followed and the oil gets changed when the monitor gets down to 20 percent or less, Usually 10 to 0 percent. Driving is mostly highway with frequent full throttle acceleration.
If anything this has shown me that going above and beyond on maintenance isn't necessarily going to get you anything extra. Sure some engines are more prone to sludging and whatnot, but on most engines dino oil does just fine.
