Looking at a possible purchase of a 2010 Toyota Tundra with the 4.6 liter motor. Regular cab with topper. Auto 6 speed trans. 4.10 gears. Anybody have a Tundra with the 4.6L motor?
Mostly concerned with fuel economy, rated at 14 city, 19 Hwy., and 16 miles per gallon combined. What are your real world calculated miles per gallon that you guys are getting? I have heard Toyota's really don't get what they should in the mileage department. It would be my first Toyota truck.
Thanks for the replies.

If your going to buy a tundra, buy the 5.7, better engine, better power, almost identical fuel mileage...in my 2018 DC 4X4, With Heavy E range 33" tires - I am averaging right at 16 MPG around town. I did add a K&N filter (not sure how much this helps), but overall very satisfied. You will also get 4:30 gears - if that matters to you.

the 4.6 is a great engine but in a tundra it's under powered, also every 90,000 it's due a timing belt which gets expensive. as has been said mileage is the same

the 5.7 can be had with 4:10 gears, all with the towing package have 4:30s, non towing package are 4:10. compared to these later model trucks yes they are worse on gas but they are the most reliable 1/2 ton out there period.
the big thing they lack is a rear locker, the traction control sucks.

The 4.6 does not have a belt that needs changed, it has the chain. The previous version, the 4.7 had a belt.

The 4.6 has 310 hp @ 5600 rpm; 327 lb.-ft. @ 3400 rpm.
My 2001 Tundra had 245 @ 4800 RPM 315@3400 rpm and it felt like it had enough power for me. I never tow but if I had a full ton of wood pellets in the bed it still pulled hard. The rear leaf springs would be maxed out though, the first generation had poor springs/payload.

My current 2018 4runner is a V6 and it has 270 hp @ 5600 rpm 278 ft-lbs. @ 4400 rpm. It really needs more low end torque. My old 4.7 felt like it had twice the torque.

I test drove the 4.6 when I was deciding on the 4runner/Tundra last year. The 4.6 seemed to have the edge on the 4.7. So the engine was fine for me, but I picked the 4runner as a better dog hauler/hunting rig. If I would get a Tundra, I would get the 4.6 because the 4.7 was always competent for 180,000 miles.

I have a 2013 Tundra, base model, doublecab, 4WD, tow package, 4.6 L, 6 speed, and still running OEM-size tires. I can get the rated mileage if I want to, but that is with light loads, easy foot on the go pedal, and staying at 70 mph or below on the highway. Have even hit 20 mpg on occasion. At 75 mpg 18 mpg is more likely. Cold weather at 75 will drop it to around 17mpg.

If you run oversize and/or heavy lugged tires you'll lose gas mileage. A heavy mud/snow tire can take 10-20% off gas mileage. If you travel 75+ mph or spend a lot of time in mountains your gas mileage will suffer. If you have a heavy foot and/or brake excessively yada yada yada. I would expect that if you cruise open highways out west at 75-80 mph your gas mileage will suck. In summary - the mileage depends on your driving and optional equipment.

I also had a 2005 Tundra doublecab with the 4.7 L and 5 speed. Gas mileage for me was just about identical under same driving conditions.

Towing is a whole other ball game. A light, open, low profile, single axle trailer with a total weight below 2000 lbs might drop mileage from 19 down to 16/17 mpg. A high profile, single axle enclosed trailer around 3000-3500 lbs can drop it to 10-14 mpg highway.

I don't pay as much attention to local driving mileage. When I've bothered to calculate its been in the 14-16 mpg range.
