I COMPLETELY AGREE ON FACTORS OF THE SLUDGE MONSTER!! NEARLY ALL PETROLEUM BASE LUBRICANTS ARE THE SAME, THE ADDITIVE PACKAGES WILL CHANGE THEM SOMEWHAT BUT NOT MUCH. SYNTHETIC BASE OILS ARE FORMED FROM ESTERS AND DI-ESTERS (WHICH ARE CHEMICALLY FORMED FROM TWO THINGS THAT WE WOULD NOT WANT IN OUR CRANKCASE, AN ALCOHOL AND AN ACID) BUT WHEN THEY ARE COMBINED MOLECULARLY THEY FORM A FINE BASE FOR SYNTHETIC OIL THAT HAS THE BUILT IN RESISTANCE OF CONVERTING BACK TO EITHER ACID OR AN ALCOHOL.
A GOOD FRAM OR HASTINGS OIL FILTER WILL FILTER OIL BETWEEN 20 AND 25 MICRON AND AMS/OIL HAS A FILTERS THAT FILTER BETWEEN 3 AND 4 MICRON, THEY ALSO HAVE A BY-PASS FILTER SYSTEM THAT TAKES THE SURPLUS OIL ON THE RETURN PATH AND PUT IT THROUGH THIS LARGE 1 MICRON SPIN-ON FILTER, WHICH ACTS LIKE A NEW OIL CHANGE EVERY 25 OR 30 MINUTES THAT IT TAKES FOR ALL OF YOUR OIL TO HAVE PASSED THROUGH THE SYSTEM, AND IT ALSO ADDS ANOTHER QUART TO YOUR OIL LUBRICATION SYSTEM, WHICH CARS AND TRUCKS HAVE SMALLER SUMPS AND HIGHER RPM AND MORE HEAT, THEY CAN USE THE EXTRA CAPACITY. A SIDE AFFECT WITH SYNTHETIC OIL IS THAT YOUR CRANKCASE TEMPERATURE WILL MORE THAN LIKELY DROP 20 TO 25 DEGREES, F., WHICH IS WHERE THE CRITICAL TEMPERATURES ARE FOR ENGINE OIL LIFE. THE TEMPERATURE DROP BECAUSE OF LESS FRICTION ON THE CRANK AND VALVE TRAIN, AND LESS FRICTION MEANS MORE POWER. I INCREASED MY FUEL ECONOMY BY 15% RUNNING AMS/OIL 5W30 TURBO 100% SYNTHETIC AND TWO AMS/OIL FILTERS, BY-PASS AND FULL FLOW.

I HAVE AN 80 GMC DIESEL WITH A 5.7 LT ENGINE IN IT, &. EVERY MISTAKE THAT A DESIGN ENGINEER CAN MAKE IS RIGHT THERE, ANYWAY I HAD AMS/OIL 15W40 DIESEL OIL IN IT A FEW YEARS AGO WHEN THE CONNECTING ROD LET GO AND WHEN I TORE IT DOWN YOU COULD EAT OF THE INSIDE OF THE ENGINE IT WAS SO CLEAN, ABSOLUTELY NO SLUDGE. IT HAD AN ASF-15 SPIN ON FILTER AND A BY-PASS FILTER SYSTEM AND A LIFE TIME LT-52 AIR FILTER. FROM GRAHAM
