Full-flow filters install directly into the line of oil circulation. The full flow of oil passes through the filter as the oil journeys between the oil pump and engine. A full-flow filter must be capable of removing and holding contaminants without obstructing oil flow to the engine.

OMPARED to microscopic dirt particles, your engine is a Goliath, roaring with heat and energy as it converts fuel into raw horsepower. But despite all this power, your engine is extremely vulnerable to the threat of microscopic engine dirt. In fact, if left unchecked, this tiny menace will dramatically erode your engine's performance and can eventually cripple it completely. That's where AMSOIL SDF Full-Flow Oil Filters come to the rescue.

Most conventional filters on the market use a thin layer of porous filter paper as their filtration media, which compromises their ability to catch fine particles. In addition, these filters have almost no extended cleaning ability since their media have a low capacity for storing dirt.

Because of their limited filtering area, most conventional paper filters display good flow characteristics but are limited in their capacity and longevity. They become obstructed relatively quickly, opening their relief valve and allowing unfiltered oil into the engine. Their light- weight construction also makes them susceptible to degradation.

AMSOIL SDF FILTERS WORK BETTER -- LONGER!

AMSOIL Super Duty Oil Filters (SDF) feature an advanced fiber media offering the ready flow of oil hard-working engines demand with superior capacity, efficiency, and service life to that offered by conventional paper oil filters. In fact, the SDF offers up to 25% greater efficiency and up to 300% more capacity than other popular oil filters as tested according to the Society of Automotive Engineers (SAE) HS806 method.

The AMSOIL SDF may be used for intervals of 12,500 miles or 6 months, whichever comes first.

When you look at the big picture, the overall superiority of the AMSOIL SDF Oil Filter makes a big difference.

The AMSOIL Super Duty Oil Filter offers superior efficiency and capacity to those offered by other popular filters. While some other filters offer good efficiency, hey do not offer nearly the capacity of the AMSOIL SDF. For those who wish to extend their oil drain intervals -- or even for those who simply go too long without an oil change -- the extra safety offered by the AMSOIL SDF Oil Filter makes a big difference.
