#97 of 106 Re: Real-world mileage with 2000 SR-5 4WD [papychunty]
Feb 24, 2010 (11:01 pm)
With 145,000+ miles now on the odo, I am still getting the same fuel economy numbers I got once the driveline was fully broken in at around 20k miles. I have kept track of the mileage of every tank of gas since new, and the long-term average since new is about 18.7 MPG, on a 4WD version with the lower-than-standard (4.30:1) rear axle ratio that comes only with electric locking differential.The worst mileage i ever obtained was 15.78 mpg, and the best was 24.28 mpg. Tires are stock size 265-70R16, fairly hard at 35 PSI. So far, the only "failures" have been the plastic gear rack in the automatic antenna ($28 part cost + 1/2 hr to install), the HVAC blower resistor ($22 + 10 minutes to install), and 4 or 5 tail-light bulbs. Truly the best vehicle I've ever owned. Completely leak-free and uses zero oil (Mobil 1 10W-30) between 6K mile oil changes. The 2003 Gen-4 is a completely different vehicle from end to end. For 4WD use, I'd prefer a pristine, well-cared-for 1999 or 2000 Gen-3, before the electronic traction control system was introduced in 2001. The 3.4L V6 is looking to become another example of extraordinary Toyota engine reliability, with many examples going more than 300K miles without major service. I'm not sure how the long-term reliability of the later 4.0L V6 compares with the 3.4L engine. Regarding the 2003 model, as a general rule I'd never buy the first model year of a new model, even with a Toyota. There will always weaknesses uncovered that are corrected in the first two years of production, as well as detail improvements.
#98 of 106 improve MPG?

I live in Colorado and have a 2009 V8 4wd. I have two questions on saving gas:
1. Being at 5500ft elevation, is it ok to use 85 octane gas and will I get similar gas mileage/performance?
2. Will shifting into neutral while coasting down hills then back into drive at about 40 mph harm the transmission over time?
Thanks in advance. I realize this may been addressed in other posts but I could not find it.

85 should be fine at your elevation.
Shifting to neutral going downhill will burn more gas than leaving it in gear (not to mention that it can be dangerous and is illegal in most states).
Counterintuitive, but if you leave it in gear and take your foot off the gas, the fuel will shut off and the turning of the wheels will keep the engine running. If you put it in neutral, the fuel won't shut off and you'll waste gas keeping the engine idling.

I appreciate the reply. Counterintuitive is right. Especially when you see the RPMs drop quickly and are less than when in gear.
Would you address the potential engine damage question? Thanks.

People in the mountains have been running 85 instead of 87 octane for decades without issues, so I don't know why your 4Runner couldn't manage. The gas cap says to use regular unleaded I assume? The engine controls will compensate.
There may be a blurb about it in your manual too.
If premium is recommended you may get better mileage with a higher octane, but not if the engine is tuned for regular.
Hopefully an owner will pop in here with the real scoop before I stick my foot too far into it.

It is depend on the brand of the gas.. if you are using 85, make sure it is from top tier gas retailers.
from my experience, when I coasting down hills from 8000 ft - 4500 ft ), I shift it to 3rd gear. ( so thats way I don't use my brake).

Concerning braking with the engine, I have always been told that it is easier to replace brake pads than transmissions. Has the thinking changed about this?

Bought 2003 Ltd V8 new and now have 55,000 miles on it. I get 16mpg/twn and 19 mpg/hwy consistently. I am smooth on the vehicle in town coasting to stops and sometimes coasting on hills (Colorado). I use the lowest octane available since using higher makes no difference. If I do the speed limit (75) on Interstates, the mileage drops to 17 mpg. I try never to drive it over 2000 rpms which is about 62mph. Yep, other drivers hate me, but I don't care. The vehicle is great and has never been in the shop. I do my own oil changes and inspections while on the lift (Peterson AFB auto shop). I run Goodyear Wranglers (17in). I will keep this one for a very long time and I don't mind the truck ride because it doubles as my truck. I had a Grand Cherokee before this and will never buy another Chrysler product. Thanks Toyota and Merry Christmas to all. JG1

After the first 600 mi. I'm averaging 20.0 mpg with about 70% city driving w/ AC on. That's outstanding. Can't wait to see what happens when it's broken in.

Yes, I've noticed gas consumption increases rather dramatically going from 69 mph to 75 mph on our T4R V6.
