5 months exactly on this oil, somewhere around 4,300 miles. 71,316 miles on the vehicle. 1 mile commutes in the morning for work M-F. I don't know what the differences are but there''s like 50 different bottles for Total Quartz 0W-20. I get it for $Free.99 at work so it's what I use in this vehicle. The bottle says exactly TOTAL QUARTZ 9000 FUTURE GF5 SAE 0W-20 SYNTHETIC FUEL ECONOMY ENGINE OIL, Made in the USA from domestic and imported materials.
