I've used Amsoil's Dual Remote Bypass Oil Filtration System, and an Absolute Efficiency air filter on my 1997 GMC pickup since 2007. I use oil analysis, and Signature Series 0W-30 with extended oil change intervals. With oil analysis I found fuel dilution, and a coolant leak in the intake. I used a sealer to stop the leak, and Amsoil’s Performance Improver to clean the fuel injectors. Later oil analysis confirmed the leak was stopped and the fuel dilution was corrected. Because of Mr. Gratta, I was able to avoid over $1,000.00 in repairs.
