Real Life MPG 5.3 / 6.2

[RST Dana]

I didn't use a casio, I used the calculator built in my iPhone, but that calc was as follows:

487.4mi/23.4gal = 20.83 MPG, my ride said 20.7, I'll chalk up the difference in the small variance in how much fuel added, and to whatever degree the onboard is not accurate.

BTW, the ECM knows exactly how much fuel is injected into the engine (knows how much fuel per injection, and counts injections), and the odometer is probably pretty accurate, so my assessment is that the onboard computer is pretty close...validated by this calculation.

My boat's ECM calculate's fuel used, and is usually within 0.1gal of what I add, on a regular basis...
Net, I think this tech is pretty well hashed out by now.

Maybe, previous models all seem to inflate the reported mileage versus manual calculations. It’s all over the interweb as well as a few other post on TYF.
Casio was meant to make the younger crowd think. Most have never used one.

Had a casio, a Sharp, and an HP growing up...and can still use a slide rule...but that is dating myself!

Zactly. Still have my slide rule too. Kids now look at it like it’s a rotary phone.

Yep, I try to focus on what my DIC tells me not what the nay sayers think.

I know how much money I pay on gas and aint much more than what I payed on my Daily driver Jeep…

I don't know if this makes sense, but feels like I get better mileage from top grade stations--exxon, mobile--than Sheetz and WaWa gas.

Definitely true is my experience. My best mpgs come from using Chevron, Mobil, Sunoco in that order.

I've been almost exclusively using Costco, its only about 7/8 of a mile from my office. Currently here it is $4.45 for 92 octane...that is what delivered that almost 21 mpg I reported. It is only about $0.20 higher than 87 at most of the other stations in town.

The other major provider here is KwikTrip, but their premium is non-oxy (which is AWESOME), but coms at a price (currently $4.999).

Haven't hit the BP, Shell, or Holiday yet, they are proud of their premium too.

One way of measuring value or efficiency is by cents per mile. If KwikTrip's fuel delivers 2 mile more per gallon it may make sense to use over the others that cost less and deliver lower mpgs.

FWIW,
Usually, big name company stores receive product from their terminals. However, tankers sometimes will pull from various terminals depending on supply/demand. Small, mom and pop stores maybe be getting Chevron,Sunoco, Exxon, etc without even knowing it.
I have delivered a few gallons of product for a few years for my father is how I know this. We pulled 99% Chevron, and only had less than 5% of the delivery locations tagged the same.
Another pet peeve, is price spread. $.””About 30 years ago, the difference between grades was no greater than $.05 when we loaded the 8900 gallon tanker. Once it hit the retail locations, boom! Anywhere from $.20 to $.40 spread.
At least I can say I pumped full service Gulf premium for $.32 in my life.

As you were…

Thats what P'd me off and I switched to mostly all diesel. Most vehicles we really liked were premium only, and paying.30 more I'm ok with.... but the spread is upwards of .80 currently in our area. When you calculate that over the lower mileage and life time you will own it, its very significant and a blatant money grab. I realize diesel doesn't look so exciting currently, but premium and diesel are only .20 apart and I'm going 40% further on it, so its still viable....

Many posts have indicated the only “real” way to check your mileage is using your Casio calculator and fuel receipt. The info screens only give you a warm fuzzy feeling, kinda similar to the feeling your salesperson gave you as you left the lot.

I'm actually getting better numbers when using the calculator than reading the dashboard... so... more than pleased with the consumption
