My average mpg continues to increase from my initial post. I am using 10w30 Mobil 1 full synthetic oil. I am maintaining a spreadsheet to calculate my fuel consumption. I consider my data to be extremely accurate.
To date I have driven 6959 miles and have consumed 292.85 gallons of gasoline since my April 1 purchase date. This calculates to 23.763 mpg. This is up from the 23.51 mpg I recorded on my initial post 2 months ago. My last 2 fuelings are in the 25+ mpg range. This is a combined city and interstate highway. I usually carry a bicycle, small Engals DC refrigerator, some tools, and misc boat stuff, weighing approx 250 pounds of stuff , plus my 200+ weight. My tire pressures are per the manufacturers recommendation. Thus, it appears my mpg continues to increase as the drive train parts wear in. The mpg figures are acceptable and above the Nissan official figures. But not excellent for an under-powered 4 cylinder engine. I wish the diesel were avaialble in the US.
