Gas Mileage

[oilmpg]

I learned that even slightly larger tires make a big bite out of milage. The stock 275/65 18 tires gave me an averrage of 20.1 over 6500 miles. I drive almost all highway or 55mph back roads.

I put 275/70 tires on it and the milage dropped to 18. You need to check your odometer against a GPS or just do the math. These tires are 33.2" so when the odometer says you drove 300 miles you actually drove 309 miles...a 3% difference which is worth an extra 1/2 mpg. Those with 35" tires are driving alot further than their odometer or computer indicates so the milage may not be as low as you think.

Well crap, I was expecting to be in the low teens highway, and mid teens city. But I'm averaging 16city/23 highway. Dunno cause I haven't done any mods to the truck. But every vehicle I've owned has always got better gas mileage than the window sticker states.

WTF are you complaining about? Those are incredible numbers.

Anyhow, just recently I loaded my bikes, gear, accessories, etc. onto the bed (over 850+ lbs) and managed a 16.5 mpg traveling 80-90 MPH on the highway. That ain't bad is it?

Oh I wasn't complaining I was been sarcastic. I only could average about 9mpg in my 88 F-250 4x4 x-tended cab long bed truck. If I towed anything I was lucky to get 6mpg.

I have an 08 DC TRD 4x4 5.7 and my last fill up showed 18.4 I was driving 65-75 on the highways & some in town driving as well. I haven't pulled anything for an extended period of time so I don't have a good number when towing.

What kind of truck to you have? DC, 4.7, 5.7, 2wd, 4wd???? Those are excellent numbers.

When you get the 23hwy economy is that at 55-60 mph speeds?

Thanks for the info, great job with the fuel economy.

In this age of high fuel costs, the truck manufacturers are producing vehicles that routinely operate in the 18 to 20mpg range. With Toyota's 5.7 V-8 engine & 6-speed, you get one of the most efficient systems out there...without shutting off 4 cylinders occasionally (GM trucks). This engine has the power but if you use all 381 horses, you better have the feed-bag full. If you drive like you're about to run out of gas, you can squeeze impressive milage out of this truck...like 20.1mpg over my first 6500 miles (very little city & no towing). No mountains up here...a few hills and I run between 60 & 70 on the highway depending on the grade. Cruise control hurts milage in my case.

This truck is way more efficient than my F-250 diesel 6sp. manual. This shocked me. Even when towing a large 8000# box trailer, the price difference between diesel and gas makes the Toyota a cheaper vehicle to operate.

I drive 1000 miles a week on business and reimbursement is by the mile. Good milage is money in my pocket. The Tundra will get 20mpg if you allow some extra time and drive 65mph. The larger Nittos I put on dropped the milage down to 18. If I drive 40K miles on the Nittos I will spend $600 more on gas than if I stayed with the stock BFGs. But the truck looks better and I gained 1/2" of clearance. I still love the Tundra. No issues after 12K miles. I sold my diesel F-250 and my work car to consolidate down to one do-all vehicle. It tows my 8000# box trailer with ease and this wiinter will be the test. If I can squeeze 10mpg while towing then the Tundra will fill the bill because the F-250 got 12mpg towing and 20mpg empty based upon 8 years of use. Gas is $.60 to $.70 more expensive than diesel fuel so the Tundra should be a bit cheaper to run.
