Engine Oil in a 2001, Toyota Tacoma gets GREAT test results. Edmund Loughran has had NAPA test the condition of the engine oil in his 2001 Toyota Tacoma not once, but 3 times. "A great service that keeps me informed on the condition of my engine". With over 73,000 miles on his car, an oil analysis report (a service provided by NAPA) showed excellent oil viscosity with Wear Metals, Contaminants, Additives, Fuel dilution, Fuel Soot and other potential engine risk factors well within the normal and safe ranges. This incredible report provides any vehicle owner an excellent report card on the engine’s internal condition. Just like having your blood tested for abnormalities during a physical, NAPA’s Oil Analysis Report can identify abnormalities which could be an indication of abnormal wear or imminent danger to your engine. Click on the two highlighted sections below linking to his report: NAPA Oil Analysis Report and associated Oil Analysis Report Interpretation Page. The report’s interpretation page explains in detail how to read the report which is on the back of NAPA’s oil analysis report. Pay particular attention to the very first report date compared to the subsequent two - the oil went from abnormal to normal after the installation of the Fuel & Air Saver™ System.
