One thing you have to consider is the quality of the filers. At one time the Fram was considered the best and I used them back in the 60's on the race motors. I also used onr on my first 280 several years ago. When I crossed the lines when installing the engine in the truck. well the bearings didn't last long. I realize my stupid factor has increased over the years, but I also found out the Fram is now made offshore and is not a very good filter. Wicks is considered very good and makes allot of other name brand filters. Iy's sad that we can't trust some of the items we relied on back in the day. Quality is replaced by the all mighty buck.
