Placebo Effect? V-Power "Nitro" After 113 Miles

Wow - fairy fast!!!

 

spelling never was my strong point

 

Could just reset the whole system and see what the gauge reads than. If it's in the tank you'll know. Better than running out of gas.

Conflation at work: this just a miles per tank game.

 

Yikes another long thread.
In California, every grade will have 10% ethanol and also RFG so equal energy content (MPG) all grades (in theory).
Of course, YMMV.

 

Well as long as it is "safe", I think we as owners have the right and freedom to embrace any ownership behavior, even if the benefits are probably mostly placebo.

I didn't or rarely filled my Prius with anything but regular.
My current vehicle is rated to run on regular.
Same thing, I only full moon, rarely fill with Premium.

But there are "placebo" affect behaviors I think everyone sometimes does embrace.
For decades now, I have run occasional treatments of Techron through my vehicles, 1-3 times a year.
I'm not sure it helps anything really. But it's a old ritual, and if it's ONLY placebo affect? I can live with that.

So in short, if you feel happier running Premium? I certainly wouldn't stop you.
I'm not recommending anyone do so, but if you determine you are happier with performance doing so, and can afford the cost hit? Owners choice.

 

Just keep that can of "petrol" in the "boot"!!

If there's one thing you can count on in life, it's Toyota's propensity to BS the mpg. Starting with that 62.7 mpg and guesstimating with a 5% BS factor, that'd be 59.6 mpg (62.7*.95). Comparing that to your calculated 71.4, that's a reduction to 83.4% (59.6/71.4*100).

The one way I can see that happening is a very full fill-up with a the high octane Shell, followed by a regular (stop at the first click) fill-up this time? This is somewhat corroborated by the miles per tank. Even then, I do not know: I never see the displayed mpg lower than calculated, and that's quite a difference.

 

Ok, not significant. Strange though, that the displayed mpg is much lower, something amiss. Stay outa casinos, lol.

 

Yeah 700 miles is 700 miles. Intriguing... (in Spock voice).

Maybe the pump shut off early on that last fill up? Calculate the next one: if it's oddly low that would point to that.

 

Would have been $7.05 difference here.

 

I suspect it was a computer glitch - the one which detects that the tank is full. I'm not sure how it does it, but I suspect it's not an accurate method. Could be a one off - the time it did something similar for me was a one off - but wasn't as pronounced.
