We bought the Suburban in Sep 99 and have driven it 15K miles. It seems that any highway travel uses 15 mpg whether just the 5 of us or fully loaded with luggage etc. Around town is consistently 12.5 mpg. With a 40+ gal tank, we found that Williamsburg Va is a single tank away from our home in southern Maine! Ken |

| '98 Jeep GC 5.2 avg 15.5 to Tampa and back. 12.5 around town. | |
| With mostly highway driving I ave 16 mpg. I am also easy on the go pedal. | |
|
|
| First 1,000 miles mixed city/hwy (mostly city) 18.5 MPG. Expect it to get better after break-in. | |

50% highway/50% county roads in the Sierra Foothills (going up and down + or - 2000') Only use 92 Octane. 201 miles - 14.2 mpg 428 miles - 15.9 mpg 702 miles - 16.6 mpg Trend is right. Jim |

Proper tire inflation means better gas mileage, longer tire life and reduced air pollution. A 10 percent improvement in gas mileage would keep about 13 million tons of carbon dioxide out of the air in the United States. You should check your tire pressure twice: once when cold and then after driving. The first reading is from a cold tire, and it's the accurate one, while the second is from a tire that has warmed up from rolling on the pavement. The second reading will be a bit higher than the first. The auto manufacturer has specified tire pressures for cold tires, not "warm." Also, a cold engine runs worse, consumes twice as much gas as a warm engine, and wears out sooner. Finally, I've always felt that all vehicles should use washable air filters (such as K&N). They pay for themselves in a couple of years and increase air flow for more horsepower. This (slight) increase in horsepower means the engine doesn't have to work as hard to move the vehicle, and increases your gas mileage. |

| I don't understand what you wrote (#95). What is the point of checking the tire pressure after the tires warm up? Curious. | |

Unless you have an air compressor at home, you will have to drive somewhere to put air in your tires, thus "warming" the tires. You need to check the "cold" and "warm" tire pressure to know what the difference is between the two readings. At the gas station, you'll know the amount to "overfill" the tire. (granted, this will probably be 2 or 3 psi) Checking the cold and warm tire pressures will only have to be done once a year or so: as a tire wears it will have varying differences between "cold" and "warm" tire pressures. This may only add up to .5 to 1 psi difference over the life of a tire, but if you want optimum gas mileage... |

Warm weather mixed driving is 25 - 26 mpg. Cold weather mixed driving is 20 - 24 depending on how cold it gets in Ohio. Long Summer trip on freeway with my lead footed wife driving 25 mpg. |

| 350 Vortec, 2WD . . . we get a dribble over 15 mpg consistently. No road trip yet, but will know soon. Cant complain, gets the same whether we have all 6 of us or just 1. | |
