4Runner Gas mileage tips
Hi there folks, I have a 95 4Runner sr5 4WD. Gas mileage is an issue of course..here are a few of my observations.
1. The 3vz an 5vz seem to like premium gasolene and preferibly a brand like Mobile or Chevron. On regular gas on my 3vz-e around town i get about 180-200 miles per tank. When i use Mobile premium it goes up to 250-260 miles per tank..a difference of about 70 miles.And this is driving around town. I have also got poor mileage using premium gas from other companies..which tells me that the gasolene is not the same. I have been using one gas station now for months and am constantly getting 250-260 miles per tank. and my car is heavy with a winch and 32 in tires. The 5VZ is a more fuel efficient engine and should do much better than the 3vze.
2.I have added a hood scoop to my 95 4runner which allows cool air to cool the large Aluminium intake manifold. This manifold gets very hot and reduces volumetric efficiency due to hot air entering the combustion chamber.Without a hood scoop one cannot hold the manifold after a drive..it is HOTTTTTT..mostly getting blasted from the hot radiator air from the fan.Mine is cool to the toutch after driving..i am sure it helps with my fuel economy. Most modern cars now use Plastic intake manifolds for this reason. If you have a 96-2002 model with a hood scoop i suggest you cut away the plastic from the inside to make the hood scoop active ..it will help alot.
3. I also have a k&n filter and Platinum+4 plugs..remember also that Tire pressure is key..If you do alot of highway driving look at your max tire press (ON THE TIRE) and pump it up to 10 lbs less than max. Freewheel hubs are a must too if you can afford them.
4. Install a vacuum gauge too..lots on ebay..Its a wonderfull tool for engine diagnosis and to curb bad driving habits (throttle). It can tell you if you have a vacuum leak or a bad sparkplug or wire..It also tells you your throttle position and if you are in the right gear for the speed you are in...Sounds like a joke..but its true..it helps me alot with gass savings....:ENJOY..MILO
