No apology needed. I am the kind of guy who just follow the manual. And for engine oil, I usually pick the cheapest ones but satisfy the requirement (standard) set by manufactors; and I don't use gasoline that is more expensive than the one suggest by the car manufactors. They make the car, so I guess they know the car the most. I guess in a certain way, we are both the same.
As for civics drivers, I just thought there are more honda civic drivers that are more into cars than those who own MB/BMW's.
