Also I should have noted that after a couple of thousand miles that high speed city driving is proving to be more efficient mpg wise then highway. What I mean by high speed is like 35-40 mph. 25 is decent also but mostly where I live it's 30-40 average. I will also say it's way easier to drive it efficiently in the city with how it coasts to a stop and the gearing. Highway it seems it can't decide what gear it wants to be in 5th or 6th alot of the time with slight inclines and stuff. I do believe 6th may be too much gear and not enough engine to effectively stay in it which alot of Tacoma owners will say also. to combat this I will be switching my focus to more aero then weight for now. I was looking at (when money permits) investing in a aluminum skid plate that more acts like a belly pan for at least half the truck which should clean up underneath alot. I also have been looking into adding a stealth light bar. It goes behind the lower grill and basically acts like a grill block or at least I plan on maybe modifying it so it completely blocks the air also. Currently I have an almost full upper grill block for the winter but a permeant lower that has an additional function would be way better for year round. I don't plan on towing since I got the 6 foot bed so I won't worry about adding the hitch or anything too. That's my update on my plan so far

I know this is old now. I have the same truck but a 2019. Same goals. Donít wanna do crazy aero stuff or ruin my truck being a truck.

Like another user mentioned, Iím lowered with the SOS kit. I have not done an alignment yet. Put about 600 miles on it so far. I also have a WAI with a cone filter and tires are at 40psi. Thatís about it so far. I can get 26mpg on the highway averaging 70mph. Mostly dead footing it. No cruise. No PNG.

Next step is shorter tires to lower it a bit more and effectively lower my cruising gear to reduce shifting on the highway. Then a header with exhaust wrap and a partial grill block.

Have you done anything else so far thatís helped?

I've noticed that 40-50 mph seems to be the sweet spot for any stock Toyota trucks I've driven. Although that was mostly manual transmission trucks, so could be put it in the highest gear and just cruise at low rpm.

It's probably a high enough speed that the engine still has some power in highest gear, but low enough so that aerodynamics isn't hurting too much.

Interestingly most manual toyota trucks seem to have lower mpg EPA figures then their automatic counter part, I'm guessing it has to do with final drive ratios

Old post, but I would not go smaller diameter wheels/tires, as truck gear ratios already tend to run too high RPM at highway cruise. Anything to bring the RPM down at steady cruise.
