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

Yes, that's fairly normal early on a trip, particularly suburban driving. Mine reads l/100, and the average is about 4 avg. But starting a trip, it might go up to 9+, down the next hill, back to 2 and swing back and forth for the first few kilometres, ending up between 3 and 5 - the longer the trip, the closer to my overall average of 4. Not so much with Motorway driving though which is more steady.

 

Are you paying with a credit card? If so, why do that?

FWIW, you're not alone; @bisco does the same thing.

 

Fuel gauge showing full maybe the sender is stuck ?

 

Congratulations - maybe you've made history with the first?? (at least on PriusChat)

 

Here in Socal, Arco advertises their gasoline as "Top Tier", so lord knows what the straight skinny really is. I remember when I worked for Chevron, any brand stations running out of their brand of gasoline would, as needed, get gasoline from another brand; the public was never informed. Also, oil refining and gasoline production are batch processes which can yield variations in output. I don't know how much trust you want to put in the oil industry and their statements. I can tell you stories about what I saw and heard....
All I know is the auto industry is more carefully regulated (in California at least) than is the oil industry. Someone ought to compare truth in advertising performance of these two behemoths; it would make for interesting reading!

At least you have a heart! Some in the public domain (need I mention names?), have none!

To the OP, you can always pick up an app to monitor your timing advance over time to see what the max advance is with various fuels.

 

Neighbor, I guarantee the best way to ABSOLUTELY reduce the noise in a Prius is.... wait for it.....!!! Make sure it says "Prime" on the car! No ICE running; no noise! Ahhhhhh, nirvana!
And, I recently raced a very hurried Gen4 taxi a few days ago; ate him alive! 2-3 car lengths ahead of him at 50mph. This guy was weaving in and out of traffic, trying to get somewhere in a big hurry. I love my Prime!

Smog reduction and abandonment of lead in gasoline. Cheapest way to reduce some smog components, but ethanol does reduce mileage. Also "big corn" loves the ethanol subsidies!

Ethanol is a much kinder way to boost octane.

Keep history in mind:

We got high-octane fuels ~100 years ago when automakers realized they could offer much higher engine power in small cheap engines.

When faced with the technical problem of increasing octane ratings, the petro business knew in 1920 that they could add ethanol to achieve their goal.

Their problem was that everyone knew how to make ethanol. Worse, they feared that people would figure out that they could just run the cars on straight ethanol and skip the gasoline.

The production of tetraethyl lead was much more sophisticated, and it could be patented and monetized through licensed production. (Never mind the bit about massive lead contamination in the environment)

Fast forward to the late 1960s- auto engineers realized that the only way they could hit the clean air demands coming up soon would be to use catalytic converters- but the lead in the gas would quickly clog and disable these converters. So they had to hold the lead but still maintain the octane rating.

Welcome back, ethanol.

 

Maybe. But I'm pretty sure that the mechanical tank sender plays NO ROLE in any of the MPG calculations.

 

I thought those mostly expired many years ago.
Are there really any direct subsidies for ethanol still in place ??

 

My guess is the nozzle you used had an extremely generous stop. An extra half gallon?

 

Yes, apparently they are still in place from what I've just read in Google, as of May 2017 article; several posters also mentioned Trump continuing support for ethanol subsidies, against objections by many.

That could be the problem - there's more explanation in the manual.
