CC I'm running Amsoil in my truck with what is called a bypass filter. The normal oil filter catches particles down to 15 micron say and the bypass filter will filter to 5 microns. This keeps the oil extra clean and being synthetic theoretically it will last forever. Well we don't take this for granted so when we change the filters, say at 20K miles intervals we send a sample of the oil to a lab for testing. The lab will report back in detail the condition of your oil and recommend changing if necessary.

This is the 3rd truck I have run Amsoil in and when the crank case holds 10 to 15 qt and a dealer telling you to chang it every 5000 miles it is a real $$ saver beside being good for the engine. I find it well worth the initial cost.
