How to increase running time

That is a very vague question... what do you mean? Do you want it to get better fuel mileage? Change driving habits, tune-up engine, properly inflate tires or even go to low friction tires and fluids/oils, remove any unneeded weight, duct-tape any seems on the front of the vehicle, avoid hills and rapid acceleration...

Really, there are many factors that can minutely help fuel mileage and/or range, but the most important factor is the driver. Sensible driving (which most people don't do) is the single greatest factor in fuel mileage. Sadly, SUVs (or any vehicle) is only going to get a certain range of fuel mileage, so don't expect more than 1-2 mpg difference.

Good luck!

Whats the advantage of a cold air intake on a 2002 Chevrolet Silverado 1500 5.3L

Installing a cold air intake kit like a K&N or Airaid will actually do both, give you a horsepower gain and better fuel mileage. you will notice better throttle response and you will not need to give it as much throttle to go the same speed as before and therefore you should see an increase in gas mileage(if you dont go hotrodding around!).

Regular unleaded or Premium ?

This is a wide range of fuel types. Minimum Octane level to run decent is normally 87. Up in the northern areas and hilly states I've seen this a little lower. Typically your choices are 87 octane, 89 octane and 93 octane. I recommend using the 89 octane or mid grade to get the best mileage and consistent performance from the vehicle. You will get better mileage from the higher 93 octane or Premium but this is off set by the increased soot and build up over time and the mileage isn't that much better to justify the cost between the Mid and Premium grade fuels.

Does the fuel filter affect gas mileage

there are lots of things that can affect gas mileage. if the spark plugs and wires are worn out, the air filter being dirty, dirty fuel filter, proper inflation of the tires, O2 sensors that are contaminated and performing poorly. the first thing to do would be that the engine is in good working order, as in no check engine light, no misfire, etc. a poorly running engine will put out terrible gas mileage. then you can start with the things i listed.

Poor gas mileage


I would start with a tune up, Spark plugs , wires , new fuel filter. Then check fuel mileage . The tires believe it or not have to have correct air priessure , This also is a factor in fuel economy.
If the fuel ecomony does not get better then you should have the fuel system check. The fuel pump could be weak pressure or a throttle body cleaning service should be performed.
The next step after this would be the fuel injector replacement. Now your are talking a investing a few bucks into the car. The most cost effective is to start with a tune up and fuel injector cleaner in the fuel tank, You can pick up the parts at your local auto parts store.
