Got my 4-2-1 kit fom Geno's last year. My oil analysis came back better at 170k than it did at 150k. Every thing dropped but chromium (rings) @4ppm. Was 3ppm @ 150k. Running Rotella T 15-40. Changing @5k intervals. The rings are working harder now than they were @150k because of a TST#6 and a heavier foot. Fleetguard and Rotella T works for Me.
