Introducing AMSOIL's High Efficiency Oil Filter

AMSOIL proudly introduces the new Super Duty oil filters for passenger vehicle and heavy duty diesel applications. Super Duty oil filters offer all-around better filtration and protection than conventional filters do.

The AMSOIL filter's rugged construction and high-tech media make it ideal for motorists who extend their oil drain intervals, drive hard, want to make their engines last or, bottom line, want the best filter available.

So What. A Filter is a Filter

The fact is, you would probably be amazed at how much engine wear could be eliminated simply by using more advanced oil filtration. In paper 881825 the Society of Automotive Engineers indicates that a joint study was performed between AC Spark Plug and Detroit Diesel Corp. The study found that finer oil filtration significantly reduced the rate of engine wear.

According to the paper, the tests regarding engine wear within a diesel engine were performed using four levels of oil filtration. They chose oil filters whose efficiency rating was very high for particles of 40 micron, 15 micron, 8.5 micron and 7 micron sizes.

The same was done for gasoline engines, except that the relative sizes were 40 microns, 30 microns, 25 microns and 15 microns.

To make a long story short, the researchers had this to say:

"Abrasive engine wear can be substantially reduced with an increase in filter single pass efficiency. Compared to a 40 micron filter, engine wear was reduced by 50 percent with 30 micron filtration. Likewise, wear was reduced by 70 percent with 15 micron filtration."

So, as you can see, any increase in filtration efficiency that you can avail yourself of will be of great benefit to your vehicle's protection and performance.

The file was not found on your file system. This means that it has either not been created or the path you have specified in $trrandom_file is incorrect. "Originally, Greg Carroll, the creator of the supercharger, specified Mobil 1 as the only lubricant to use in the engine. He hadn't heard of AMSOIL yet. After Dave Bigda, owner of Dynamic Auto, sent a sample of AMSOIL to Mr. Carroll, that decal came off."
