another good tank by nippononly

I went over the Sierra to Carson City Nevada for the weekend, only had to fill up once, yesterday morning. After that I made a day trip of about 60 miles (higher into the desert), then came back today by going up the grade (about 2500 feet elevation) into Tahoe, then up the grade (about 1000 feet elevation) out of Tahoe before coming down.
 
Anyway, total was 273 miles, 11.9 gallons, which is 23 mpg. Not too bad, especially considering the temperature was below freezing the whole time, sometimes 30 or more degrees below. First time I have ever been in temps cold enough to experience the power steering system unwilling to do its job because of the cold (I've seen it mentioned in the owner's manual, but never witnessed it firsthand).
 
2000 V-6 4WD stick shift.

I recently bought a '98 4R 3.4L V6 automatic. Right now I am getting only 16 MPG in suburban and urban driving. Haven't yet had it on the open road to test HWY. I feel like this is a bit low so I am taking steps to improve. Will be putting in new spark plugs as well as flushing and replacing all fluids. Also looking at the air filtration. I want to go with K&N but have one question. Has anyone experimented with the difference between just putting in the K&N filter vs. installing the K&N FIPK Air Intake kit? I looked at stock air intake system and it doesn't seem to be that small or constricted but I don't have experience with what improvements the K&N system would bring. Is it worth the extra money to go with the full intake system replacement ($200-$250) vs. just the air filter ($50)?

Only thing about the K&N performance systems is that they tend to let more dirt through, even though they claim this is not the case. If you really want the FIPK kit, look around for less expensive alternatives. You should still buy the K&N filter, but look at a different intake pipe. K&N overprices that kit becuase of who they are.

I have been driving about 65-35 highway-city in blistering cold MN/IA winter weather. In my last 5 tanks I have averaged (by my calculations) 18.4 mpg ('05 SR5 V6 4x4). I have used the 4wd in snowy or icy conditions liberally, that's what its for. I have also done some off-roading during this time. As for my habits:
1. Warm up for 30 seconds, even in the coldest weather. I drive gently to warm up the vehicle.
2. Keep 70 mph as max speed on highways. Trucks are not meant to go much faster. The aerodynamics are parachute-like.
3. Use cruise control a lot and maintain steady speed when not using it.
4. Don't lead foot it unless necessary or I feel like it.

air intake system to improve MPG by chibearsluv

I have an '04 4runner SR5 V-6 and was wondering if anyone had put an aftermarket intake system on their 4runner to improve MPG's and performance. If so what system would be best for the price and quality, I was looking into the 77 series K&N or AEM and Injen. Any inputs would be appreciated

The aftermarket sys have been shown to allow additional larger particles into you engine. I would not use one. Just my .02.

So how can we improve Mileage? by darambo

Anyone getting higher MPG's with a K & N filter?
 
An acquantance swears that replacing the exhaust system with larger pipes would not cost much and result in higher MPG's. What do you think? Anyone try this?
 
I'm considering buying a V6 "07 because the back window rolls down to provide cross venting for my dogs and would sure like to get the mileage up to 20 combined!
 
thanks...

My sister swore by hers until I asked to see the "before" numbers. She hadn't kept track of her mpg naturally and it was all seat of the pants guessing. Then I pointed out that if her old air filter was dirty, a clean OEM paper one would also likely bump her mpg up a notch.
 
So she just sold the car.
 
Check out the K&N Air Filters, bolt-on power? discussion - opinions are all over the map, but actual data seems scarce.

I really think any alterations you make to a new car is a waste. These cars are controlled by computers. When I look for a used vehicle I first eliminate the ones with mods. Just my .02 good luck.

'06 4x4 V6 4Runner SR5 by pmschneidau

Wife and I have had our '06 4x4 V6 SR5 since April 28, 2006. We trade off driving it every week or so. I tend to get about 21-23 mpg mixed 50/50 city/hwy. My wife consistently gets 19-19.5mpg, also 50/50 mix. I have learned to coast up to red lights, stop signs, and freeway off ramps, which I think really adds up in the end. I watch my wife drive and the foot goes straight from the gas to the brake. She's not lead-footed, but she definitely is not in the habit of coasting. I've also found that about 55mph is a very efficient speed for the 4Runner. We did a day trip last summer up to the mountains around Boise. I gassed up that morning, then filled up just before my house and averaged 25.5mpg (about 5.5 hours of driving, mostly at 55mph). I had trouble believing that, at first, but I just did the same old calculation as always. BTW, I never use my computer to figure mpg. I learned on the first tank that it's WAY off (like 3-4 mpg over the true mpg).
