| I recently bought a 2001 Acura MDX. The screen is showing that I am averaging 15.5 liters/100km. For the past week, it went down to 15.4 then tonight to 15.3. This is roughly 6.4 kilometers per liter. Is this normal? What are you guys getting? I am thinking that the past owner is driving this harder than me which may explain the poor mileage. |

| How many miles/km on the X? Did you check your tire pressure? Have the spark plugs been changed? What kind of driving do you do? |

| It has 74000 kms on it. The tire pressure is at 37 psi and I'm not sure if it has new spark plugs. |

| I can't tell you in liters or Kilometers, but in MPG I have been consistent at 17 miles per gallon in the city and 22 on the open road (highway). My 01 has 76,000 miles and the original spark plugs. Michelin All terrain with 36 psi of nitrogen fill in each |

How much do they charge for nitrogen fill for all 4 tires?? does it really improve mileage, thanks. |

It won't improve mileage at all directly, only indirectly. Obviously you get better mileage with proper tire inflation and pure nitrogen doesn't expand/contract at anywhere near the same rate as the air in the atmosphere does (air changes about 1 PSI +/- for each 10 degree +/- in temperature). So regardless of the ambient air temperature, if he sets 36 PSI with nitrogen, it will be 36 PSI all the time--summer or winter. And if your pressure never changes, you don't have to worry about taking a hit in fuel economy. Obviously, if you're really good about monitoring your tire pressure you can have this same benefit with regular air--it's just easier and less effort with nitrogen. |

| We use a location called Tire Discounters in this area of Kentucky. There is no additional charge for the nitrogen. The previous post pretty much said it all on the benefits of nitrogen. |
