We take the camry to the casino every month or so. I use this trip as a test to see how much mpg I can get. Several trips with dino oil netted me 38 too 41. Now with the 0-20w oil my high moved up to 44 and a low of 40mpg. I really dont know if there is too much difference on normal everyday driveing, my wife uses the car for work. JOE
