I also went from a 4Runner to a Sequoia. My mileage was around 14 city / 17 highway. I kept hearing about synthetic oils and their benefits on mpg's.After a lot of reading and searching the internet,I decided to give it a try. Mobil 1 was my oil of choice,that,along with the Mobil 1 oil filter.I changed the oil on a Wednesday evening,filled up with gas Friday morning and left for Chicago from St. Louis.With the cruise set at 70 all the way with one stop for food,I filled up when we got to our hotel.My figures ,checking them twice,came up to 20.6 mpg.I filled up again on Sunday for the trip home,same speed and again only one stop,this time was 20.5. I have been checking it the last 5 or 6 fill ups,driving around town and 9 miles to work, I have been getting around 16 1/2.I'm sold on fully synthetic oil.
