MotorWeek said that peolple who use synthetic oil (such as Mobile 1) still need to change their oil filter at 3K miles even though the oil won't be changed until 5K+ miles. They said oil filters are shot at 3k miles.
They also said that there are special high mileage oil filters to buy if you don't want to change the filter at 3K miles.
Either the filters you buy here in the states are absolute ****, or Motorweek is feeding you lies.
On my EDM 98 Corolla I change the oil and oil filter roughly every 9.300 miles as the service manual and Toyota say it requires, and out cars run well into the 200.000nds or more with that treatment.
Most important is to run your engine on Synthetic, if that's what it's built for. Which all 95 and up Japanese and European cars generally are.

This is what I meant. My current oil is a synthetic so I want to extend its oil capability till 3k more miles.
Decades ago would start up my engine on the front lawn...when warm opened the valve on the side of the block or at the bottom of the radiator...ran water from the garden hose untill water was clear.
Sure...oil could be changed the same way...STUPID YES but possible.
Only need is two people...a SUPER LARGE pan to catch the oil coming out the drain plug and a 2nd person pouring fresh oil in the same time. The need may be for 10-15 gals of oil...but still feasable.
Never heard of this being done...still there are some who might try it when a person has nothing else to do.
Most likely a troll. Say the OP's screen name slowly
You never know, for some these may be valid questions; leaving an engine running when changing oil, just changing a filter, etc.
To others with some sense and experience they are no brainers. But, it seems on a site like this (as opposed to a dedicated gear head site) some of these may be legitimate questions. I give credit to folks that answer them squarely.
There are regulars here that constantly give wrong info, such as: GATT requires that all cars sold in the U.S. are built in the U.S. So you never know.
