That's awesome. What's the form factor, a puck or a tube on an arm?

Next step gauging might be an inclinometer, or according to Wikipedia "...or clinometer". [I guess it's like flammable/inflammable]

For my airspeed indicator, I use a small brass tube about three inches long and maybe 1/8-inch inside diameter sticking a couple inches in front of the grill to serve as a pitot tube. I connected a hose to the tube and ran it through the engine bay and the firewall to the instrument dial. The airspeed indicator also needs a second tube to compare the oncoming air with static air, and for this I ran a second hose from the engine bay through the firewall to the instrument. It all works good.

In the interest of determining why my mileage is up or down on any particular trip, I also have an inclinometer to show the degrees of up-or-down travel for the road I'm on.

It takes a lot of things to explain differences in mileage on any particular stretch of road. Only a nut cares what the differences are. Guilty as charged.

A simple manometer?

But an electrical device would allow data logging.

Yep, a simple manometer.

About the datalogging: only if they paid me.

Last week, a highly unexpected thing happened in my country. For the first time that I can remember, Diesel fuel is more expensive than gasoline, AFAIK due to the war in Ukraine and the Brazilian refineries still having a refining profile more oriented toward gasoline than Diesel.

Same reason diesel is so much more expensive than gasoline in the USA.

Shortages from war in Ukraine and Russian sanctions
A few refineries down (one in Mexico from an Earthquake, one in Louisiana from Hurricane Ida)
South America going into winter which increases kerosene and fuel oil use
Increased air travel
Increased last minute shipping due to supply chain issues.
Some South American countries are still subsidizing diesel

Until recently I had not seen diesel more than 91 octane gasoline. Today near me:

$5.35 87 gasoline
$5.65 91 gasoline
$6.19 Diesel

This might be the most relevant aspect, now that Petrobras pricing policies are in line with international practices. Regarding the war in Ukraine, another matter of concern is the urea, widely used both as agricultural fertilizer and to make DEF/AdBlue/ARLA-32.

I don't know about neighboring countries, but I usually see either wood or LPG being used more often as a heating fuel than kerosene and fuel oils in Brazil. At least since 2012, kerosene became much harder to find at regular gas stations, yet it may still be found at some and is mostly used by truckers to ease cold starts on trucks prior to 2012 model-year.

Subsidizing regular Diesel fuel may still be effectively needed, but it doesn't address the problem properly. I am still a supporter of biodiesel and other so-called "renewable" alternate fuels, yet under some circumstances even biomethane which I tended to overlook seem promising. I have already seen some big-rigs converted to bi-fuel Diesel/CNG and some dedicated-CNG Scania big-rigs and buses.

I remember when the father of a friend of my father complained about Diesel fuel being more expensive than ethanol, 19 years ago. Ethanol nowadays has been "cheap" mostly in São Paulo and Alagoas only, yet once in a while other states such as Paraná and Mato Grosso do Sul also have competitive prices for ethanol against gasoline.

How do you explain the price oil, gasoline, diesel going up months prior to the invasion?
And if you look at a price chart the invasion appears to have had little to no impact on prices. It was going up months before and it's kept going up since.
When the war is over and prices are still going up then what you going to blame it on?

I remember a year ago gas was $2.40-$2.60/gal for 87 depending on where you were in the city. Now it is $4.50-4.60/gal.
It loses correlation on price though for me. In February when a barrel of oil was $90 gas was $3.10. Now a barrel of oil is $115 and gas is $4.50
I guess losing a couple % of supply is a green flag for a 50% price increase.

The interesting part is electricity and natural gas prices are the same as when I moved into my house at the beginning of 2021.

Nat gas and electricity pricing tends to be regulated, mogas, not much at all. Make refineries do a cost plus price like regulated items and the gouging will stop. Unsure if your ears could stand the wail the oil companies would create.
