The Fram XG7317 and Royal Purple 5W40 UOA are below. The green numbers are the Royal Purple 5W40 VOA. The VOA Sulfate By Product = 25 but was inadvertently left off the combined results sheet...
No particle count was done because with 5013 miles on the oil it was too dark for the laser to get a good read. I changed the oil and screwed on the EaO13 but decided to leave the air filter in place to eliminate that variable. Now it could be argued that leaving it in place increased the efficiency if the EaO13 shows better Si results, but I'll take my chances. I may do a 1500 mile particle count with the EaO13 to eliminate the dark oil problem and then repeat with the XG7317.
Shell 87 octane fuel with no additives, 80 miles round trip to work 5 days a week, weekend trips hit and miss lately, 5 mile trips to the grocery store and dropping kids off several times a week etc.
