I can answer for myself..
It is getting through to me anyway. Maybe not to some of you who keeping wanting to bang the keyboard about OCI's.
I KNOW full well what the difference is between severe service and "normal" Most people do stop and go driving, which is severe service.
If one drives the Interstate a lot , then that is "normal".
But, as is the rule with other types of debates....people like to parse meanings of words.
If some in here think that soccer Mom or Dad drives in "normal" mode, more power to you.
This all came about because of some pictures. Of which was the topic of my first post in this thread. Lubeowner also agreed that the problems he saw were from overextended drain intervals. His words not mine.
Even though MANY asked him for information about his pictures, we never received much. So we are left with differing views about the pictures themselves.
We don't know the exact miles between oil changes for the pictures and total miles on the vehicle. And unless someone can point that out to me, then i'll keep reminding people of that. Even though this went on for months, we still didn't get data. Nor have we had any current pictures--with data.
Don't you think that would be a simple thing to do? Lubeowner can average out the oil changes for the 8,723 vehicles in his computer system but he couldn't tell us what the mileages are for an individual picture.
I am still more than willing to drop by Lubeowners shop any day, any time of day, between Sept 25th and 30th. Just pick a day and time 6am to 9pm. Let's cut open filters. Let's see if there is any sludge in the bottom of the can. Let's have some mileage data as well.
I don't care what brand of filter. As my contention is that overextending drain intervals leads to problems with the filter. And i'll even bring my E-core ( with the old compound gasket that doesn't leak) for him to cut open. I should change oil & filter sometime this month.
