As others have said, too many variable to conclude anything. A little change in cruising speed or in wind direction on the Baltimore trips could account for that small difference.

Very possible Total Quartz is thin, in any weight.
Also possible, Kia wants purchasers of the 3.3 to use 5w30, but they may have used 5w20 at the factory.
So lets say Total is thin and possibly a 20w was installed at the factory and drained.
RGT is thick and your current oil weight is 30.
This is the only explanation I can come up with.

That may very well be the case as we don't know for certain what the factory fill was.
Maybe I'm jumping the gun here, but each day after my OC, the car's calculations were running less than before. And then the fill up was 21.7.
I had been trending upward as the engine was breaking in (my assumption). Between Jan. 15 and Feb. 12 the MPGs were 22.2, 22.9, 23.3, 23.5 and 23.4. I'm skipping the outlier of 24.5 when I did two highway trips to Baltimore on one fill up. I always fill up, and all calculations above are from Fuelly.
I'll definitely report back with after more fill ups. Hoping this was a fluke as I bought three more 5 quart jugs of RGT. If it's not a fluke I'll try to return them. I got the RGT at Tractor Supply on sale for $18. I just saw them at Pep Boys for $39 and Advanced for $42. Not in the market at those prices.

So engine is still breaking in. For the past month I was getting between 22.2 and 23.5 mpg average filling up each time and using Fuelly to calculate and keep track. All of my driving is the same. Short trips around home and once a week highway trip of 120 miles round trip to Baltimore and back.
I did my first oil change last week with 2700 miles on the odometer. I put in Shell RGT in 5w30 as prescribed. It has only been a week, but my mileage seems to be down noticeably. I first noticed it on the in-car info screen which keeps track of mileage for that trip. The numbers were down. Then when I filled up last, the calculated mileage was 21.7, with the same driving scenarios. No excessive idling or city driving. Same driving routine as usual. So the question is, is RGT on the thicker side? I assume that original fill was Total Quartz. Don't know much about that.
I'll continue to monitor but my early impression is that the RGT is considerably thicker than whatever was in there originally.
I know that I'm not driving a truck and I don't tow or haul, but the RGT says that it is suitable for use in all gasoline engines so I thought I would give it a try.
Thanks for any help.
Be careful as you will be told all sorts of things including you changed driving style. I ran into this with Havoline ProDs and got slammed as running two
different oils same grade fuel mileage changes. I went back to Valvoline and immediately fuel mileage returned. There are oils that claim to be fuel mileage oil Valvoline Daily 5w20 and 5w30 so that probably was the difference between the oils. All I know is my mileage is back so my suggestion is when you are ready for oil change go with a different brand and compare. Once your mileage is back then stick with that oil.

one fuel up is not enough to make a judgement.
What is weird is my 2018 Santa Fe with the same 3.3 allows for 5w30, 5w-40 or 10w30.
I have been using 10w30 (Delo, and 2x Pennzoil Platinum) for my last 3 changes, but my driving is to variable to really tell any difference in mileage between oils.

I don't think it was the oil. Why don't you average the MpG over a longer period, such as the entire oci, to get a better sample size. Most likely you hit some headwinds fuel variations (even at same station) happen.
With the factory fill you got a low of 22.2.mpg. With Shell RGT you got 21.7 mpg. C'mon man. Enjoy your new ride without fretting about a half mile per gallon. The difference is a mere bagatelle.

RGT is a fine oil, I've been using since sept-oct, and so far this oil has been best cold weather/all around oil were differences were not slight, but quite noticeable, and I always have same set of routines for vehicles and products on top of oil I use. You are over analyzing this slight drop of fuel and ready to return 5 jugs of one of the better oils on the market.
Wait a few weeks, and let the oil and break in do it's work before you jump the gun. Sometimes some vehicles adapt in different ways to a change in oil, and or viscosity and especially since there are so many factors at play, your next fill up try using a better fuel, or use a additive that eliminates ethanol....or the oil just needs to sort of "shear" down a bit If RGT is on the thicker side of whatever you used or was previous fill. And by "shear" I mean a slight thinning out. Either way if anything you are doing your engine a service using this oil, as I have not seen a bad UOA with this oil.

My thought is this. Fact fill likely on the thin side, but the real issue is fuel dillution. Kias are GDI, notorious for fuel dillution. When they prep the car at the factory, move it onto/off trucks, at the dealer, it is allowed to idle a lot. Idle contributes to fuel dillution. Car is new,ECU trying to find a good setup, runs on the rich aide as a precaution. Short trips, runs rich, fuel dillution.
Fuel thins the oil, thin oil drags less.

Been using RGT for the past 9 months, probably the best oil I've ever used. Gas mileage has been normal the entire time. I don't get excited about oil and I'm not "excited" in this instance either, but man my engine seems to "like" this oil. Consume less. Quieter.
Running RGT 5W20 in my police vic and it now seems a lot quieter/smoother VS the napa gold stuff that was in it from PD
Gonna run it from now on and luckily have a GOOD stash of it for next few years. Thank you AZ clearance lol

The 3.3 is not known for dilution from the few used oil analysis I have seen. It is a larger, non-turbo, lower reving v-6.
It is one of H/K best engines IMO.

You claimed a rather large fuel economy difference, it wasn't due to the oil. Outside of a laboratory where all variables are controlled you can not attribute that change to the oil.

Rather you believe it or not I seen it. 3k of one oil = loss of fuel mileage and 3k of another = fuel mileage back. My last tank was 21 mpg with some idling on Valvoline Daily Blend 5w20. Valvoline is also advertised as a Fuel Mileage oil and new oil specs have fuel mileage tests so oil companies and manufacturers believe oil makes a difference.

The amount you claimed was well beyond the realm of possibility. Actual testing by oil manufacturers have shown up to 2% difference going from a heavier to a lighter oil, your claimed gains were WELL beyond that.

Here is almost a 2% loss going from conventional oil to synthetic oil same grade. If you go to reviews on Valvoline people claimed 4 mpg increase. Not everything can be explained and why I said to run this one out to OCI then go to a different oil to see if a change. If your fuel mileage comes back then stick with an oil that works.

So you can provide data to back up your "science", where every car made was subjected to the exact same variables? Meaning every vehicle made in the last few years, was subjected to a test, where they ran X oil for 3k and then dumped and filled with oil x again to see what the outcome was? Every engine is different, every cars aerodynamics are different, everyone's fuel selection to go along with their oil is different, so show me your "science" that says It's factually impossible to gain more mpg's by switching to a different oil.
To many people like to come up with their own "science", as in if it didn't happe to me, or I never used it, but I don't believe you as "science"

You don't need to test Ibuprofen on every human being to prove it's good to reduce a fever. That's the beauty of Science.

I'm sorry but that makes little to no sense at all. What little it does make goes to support what we have all been saying that the one variable of the oil brand was not the cause of the observed fuel economy difference. The truth is that you test an oil for a fuel economy changes using ASTM D8114, not some uncontrolled seat-of-the pants daily driving method.

I'm sorry but that makes little to no sense at all. What little it does make goes to support what we have all been saying that the one variable of the oil brand was not the cause of the observed fuel economy difference. The truth is that you test an oil for a fuel economy changes using ASTM D8114, not some uncontrolled seat-of-the pants daily driving method.
