Gas Prices:Premium or Regular. Have you switched.

[DonD]

Test was stock. Read my post again. 14psi is nothing for this motor. Kia "recommends" premium. Data logs don't lie.

.. so yeah, really.

I'll use Top Tier premium, and change the oil early with Mobil 1 Extended. I want a reliable car. Don

Ive had it for a bout 10 months and only used 93. I havent been picky at all about where. Just at the cheapest place i can get it. Granted, i dont drag it much (read: at all) but haven't had any issues and am getting 26-27mpg. Thats better than i was getting on my ecoboost 4 cyl. Im not a fan of $4/gal gas (or the administration that caused it) so when it tops that, ill probably go down a notch on the octane and see if it affects the mpg any.

That fuel economy is incredible... I get like 22 average on my commute.

Are you gong by the car's estimated economy on the dash, or actual tracked with something like Fuelly.com

 

[Badal38257]

Just the dash computer. I drive 35 mile each way on the interstate with cruise set for 95% of it. On 200+ mi trips ill get close to 30.

I rarely see 20, even 22 is fantastic long less 26-27.

Interesting to read of members mileage numbers. I'm adhering to the manual break in instructions, so lots of speed changes, some quick shots up to 80-85 and back down to put some load on the engine w/o much increase in rpm but it doesn't take much for this beasty to add speed.

So, mileage numbers right now are irrelevant but according to the instrument panel, suggest that when I'm out of the break in period, the mileage will make me smile. Don

My dash computer doesn't always agree with reality - as I track it all in Fuelly.

Sucks watching the miles click away, im in the same boat. But i didn't buy mine to let it sit.

Stock 3.3 here.90% of my driving are easy highway miles. I only use 93 shell.

nice. My cluster says stuff like that too. It just doesn't always match up with reality. It's pretty close sometimes.

For this powerful engine I'm getting 27 all the time on my daily commute

I would think the on board computer is better equipped to know what the mpg is over an app on your phone. Why are you saying Fuelly is more accurate?

Eh, I'd trust my ability to add and divide over anything else.

But to answer that, yes, I would wager the app would be more accurate than the onboard computer.

The onboard computer doesn't do the math the same way we would. I use it as a ballpark and to watch for general trends, but if I really need to know more precisely I'll do consecutive fillups from the exact same pump and use the odometer / gallons used since last fillup. For longer trips that isn't possible (with any more accuracy) so the trip computer is the best guess.

... Seeing mild knock is completely normal in a stock engine, even if you run 91, 93 etc.. There is no "right" octane number. It depends on other variables such as temperature, humidity, elevation etc. I have found through JB4 logging that my car doesn't knock (pull timing) on 87 octane in Winter, Spring and Fall and most of Summer UNLESS the ambient temp is on the hotter side and heat soak starts. Let's say 80F or so... Now - even if the ECU does pull timing (knock) - it's not a bad thing.. it just means a bit less power. So again, there is no harm to the engine in any way...

There's an issue with your casual interpretation of knock and its (entirely bad) consequences. The car knock/misfire sensor is detecting issues *after* they've happened, which means the thing it's designed to help prevent has already occurred. Repeated and extreme occurrences of misfire is one path toward piston and valve issues, including potentially engine-ending damage.

Not all misfires are created equal, the more out of cycle the misfire the higher chance it can create major disruption in the timing and potentially create imbalances/damage. But no misfire is welcome. The knock sensor is there to mitigate it, not to be used as a crutch to run the engine sloppy and expect it to last as long as an engine running with little or no knock. The engine pulling timing is its only recourse for saving itself from the misfires. The ideal state is to run max power with little or no misfires. Introducing variables that can increase misfiring is suboptimal.

How did Biden do that? If we know, we can undo it right? So exactly how did anything he or the administration do that raised gas prices? Actual acts and action please.

Fwiw, those agreeing with that image are showing their outward stupid. Divide $44.66 by 14.893 gallons = $2.99 /gallon. I think we would kill anyone middle-eastern for those prices right now. Thanks Biden(?).

Posted privately in response to Deviate's message to me (they can post their private message if they want):

The last thing we need is more division and anti-fact/anti-everythingism. If you have evidence post it, otherwise consider taking down what amounts to nothing more than rhetoric aimed to further divide.

Regarding the specifics of the topic, the world was reopneing late 2020/early 2021 as the vaccine became increasingly available. Demand for many things as you might recall and see in actual forum terms (car prices) rose overnight. The stimulus (passed under the Trump administration mind you) leading to inflation on top of the higher demand. It's economics. Not politics. But you don't see me posting things blaming the coronavirus on Trump, right? Check your motives.

lol
NO

The fuelly data is ACTUAL FUEL consumed vs ACTUAL distance travelled.
The car's computer is the estimate


The fuelly website relies on your actual fuel pumped vs your actual distance travelled.

As long as you odometer is accurate - the department of weights and measures makes sure the pump volume is accurate.

Here's some raw data on the 2.5T over the last 3 months. All 93 octane. I'd say 60/40, 70/30 hwy/city driving mix. The city driving (urban too, not stop and go) really hurts the mpg. I drive very gingerly taking my time to getting to 10-20 over the limit where permitted (by traffic).
