Has anyone done runs on 87 vs 91 octane to see if they have any effect on mpg?

I’m starting to rethink my choices of lights for the roof rack after a quick trip this weekend.

Before the roof rack and lights I was around 22-23 mpg on 87 octane running around 75 mph on the highway.

Now with them it’s dropped to 14.9 mpg on 87 octane around 75 mph and 15.7 mpg on 91 octane around 75 mph.

I knew there was going to be a drop in mpg but wasn’t expecting that much.

I’m going pull the lights down before my next trip to see where it gets to.

I would not think it would be affected that much either. One thing, though, is that the effect will be much greater the faster your speed--it is not linear.

22.9 so far. Hand calculated. 80% highway, eco mode. My wife’s RAV4 PHEV is getting over 56 MPG.

For a heavy truck this is normal. The RAV4 is a passenger car. It serves a different purpose.

Last weekend drove 120 miles which was 100 miles on the highway. The average speed was 50 mph. At the end of the trip I got 24.1 mpg, which is my best reading so far. The truck has 1500 miles on it. Used 93 octane Costco gas…

The highest I have seen is around 28-29 mpg on a highway trip. This is with a bike rack attached which might affect aero.

Has anyone done back to back testing with higher octane gas to see what the effect is?

Um yeah, I knew that. My screenshot shows the mileage from my Frontier (traded in on the 4R) and my motorhome, both much worse than the 4R. I guess I was just sneaking in a little brag about the RAV and how well the PHEV maximizes the MPG. ;)

Got new tires installed yesterday (KO3 255/75R17), so let's see what happens to mpg.
