Always flush engines (if they have over 10,000 miles on them) with AMSOIL Engine Flush when converting from petroleum oil to AMSOIL. Petroleum oils create sludge and varnish on the inside of engines. If you put AMSOIL (or most other synthetics) directly into an engine without flushing you risk clogged lifter ports and at worst, destruction of the engine. Most synthetics are very high in detergent action. They will break loose the sludge and varnish the petroleum oil made in large particles. These large particles will circulate throughout your engine, potentially clogging oil galleries and ports. No matter how good an oil is, it does you no good if it can't get to all the places it should in an engine. If a component becomes starved for oil it dies!
Amsoil has solved this problem with AMSOIL Engine Flush. Just get a can for each engine and follow the directions. You'll need an extra AMSOIL Engine Filter to remove what the flush cleans out. You'll need an extra AMSOIL Oil Filter to use the flush. Paper oil filters don't filter down to a small enough particle sizes to remove all the dirt the flush will clean out.
Once you've converted to AMSOIL you have to keep the dirt out of the oil. Eighty percent of the dirt that gets into your oil comes in through the air. Conventional paper air filters will not filter out dirt small enough and will restrict the flow of air. AMSOIL Long Life Air Filters filter down to one micron, without restricting air flow.
When AMSOIL Air Filters get dirty you don't throw them away. You wash them out with dish soap and water, throw them in the dryer at low heat or hang them up to dry. Then you re-oil them with AMSOIL foam filter oil. This special oil is very sticky to attract and hold dirt. It is also designed to break down in dish detergent for easy washing. Following washing, drying and re-oiling, you re-install the air filter for another 25,000 miles or so. AMSOIL Engine oil holds what dirt still gets in it from byproducts of combustion in suspension for removal by the oil filter. Conventional oil filters don't have enough filtering capacity for long drain intervals. They also don't filter down to small enough particles to remove all of the dirt that causes wear in your engine. AMSOIL Engine Oil filters are of a depth type design to hold more dirt, and filter down to about 4 microns to remove the dirt that would have caused wear in your engine. As you can see the secret to successful use of synthetics involves more than just the oil. Flushing and proper filtration is the key to the conversion. I know of no other oil company selling synthetic oil who has it all together. AMSOIL, with over 25 years of experience in the area provides you with the products and information you need to enjoy the greatest performance and engine longevity you can attain.
