I do. I seem to get 15-20% better mileage from BP than from Mobil/7-Eleven. At least according to the dashboard (of a 2010 Toyota Kluger). Do you have the same experience? Is there an app or site that takes that into account when comparing prices across servos?
Do You Notice Petrol from Different Servos Yield Different Mileage?

Yeah, I haven't done that, but my driving conditions/routes don't change much, and presumably the car CPU records litres and kms accurately, no?
You're also assuming the following are constant across different seasons / times of year
- head wind / tail wind
- traffic / road conditions
- your own footwork
- other driver's behaviours (tailgating, abrupt braking etc)
- traffic lights' timing / wait times at roundabouts
- ambiant temperature / AC usagePedantic: Ambient temperature and AC usage can be their own individual dot points.
@skid: Fair, and I didn’t neg you. The same can be said about traffic & road condition. I guess I grouped them into the same category to not have too many dot points.
@zonra: It'd be great to have an app that took that info from the OBD, as well as the prices at the servos around, and only asked how much you paid and what fuel you put in when the tank went up, to control for those variations, and make a fair and accurate comparison.

No they don't. The only way to check is fill to fill and Ks travelled. I use this link.

15% to 20% difference comes down to driving style, stopped at traffic lights, traffic etc
Fuel types can make a difference with milage but to be fully accurate primary data for yourself from one brand to another is time consuming and is it worth it? There are so many factors when recording fuel usage and to me it's not worth it.
Let's say you did save 10% on KMs from brand A vs brand B, you constantly looking for fuel from brand A to save 10% but also, brand A may be $2.05 per/L, where brand B is $1.70 per/L that day…. Technically you're better off with brand B.
My opinion: fill up your tank with whatever fuel your car recommends

No.
If this were the case BP would be screaming it from the rooftops!
It's all in your head.
Petrol fumes produces scents. Cheers
Lot's of empty space in the OPs if he thinks that there is a 20% difference between brands
Years ago I did, but not certain if that was the brand or that particular servo. The difference was large, but I don't recall it being close to 20% like you're seeing.
Did you fill up with E10 at one and 91/95 at another because you will get less km out of E10 regardless of brand.
Course not! I'm comparing U91 with U91 😄
L/PKM is only a guide.
BP just has great marketing.
15-20% better milage lol… If that's the case other servos would be out of business. At best 1.5% -2%
BP must have "Energy Polarizers" in their fuel pumps.
In my M135i fuel economy was give or take identical between brands (98 from all)
In saying that, I have noticed previously that some of my old cars seemed to do better from some servos, but only empirical evidence really.
It's because when the op fills up at BP, they only drive downhill
That's like when I drive from Brisbane down to Sydney I get better fuel economy. Then when I drive from Sydney up to Brisbane I go though more fuel. This is also proof the Earth isn't flat.
This is also proof the Earth isn't flat.
I think you need to go to Antarctica to prove that one
No such thing. Just a wall of ice, and an entrance to the hollow Earth.
I track fuel consumption on an app. Have done for last couple of cars. I dont generally get more than 10% variation across all fuel types and brands, even when i tried e10,91,95 and 98. I seem to get no more variation than same fuel and conditions back to back. Last 3 vehicles have averaged 8-10l/100 and generally dont get a variation outside 1l/100km - except under extreme driving conditions.
Biggest variation has always been driving conditions. Urban, highway, towing or 4wding make the biggest difference and may make 20% variation. Lately, towing a stupidly big caravan equates to 30-50% increase.
Unless you've got a spreadsheet pr app tracked usage, your butt dyno is lying to you.
Which app do you use? I wish there was one that connected to OBD, tracked mileage/fuel consumption and compared prices around… I can only find ones that do one or the other. I use FuelMap to compare prices. Fuelio compares prices (though is much less compete than FuelMap) and tracks refills, but doesn't connect to the OBD. Infocar connects to the OBD and tracks refills, but doesn't compare prices. There's clearly an opportunity here for an app that does both, and simply prompts you for what you paid and what for when it sees the tank level go up.
I use fuelio. Not interested in connecting it to the car. Just use the odometer, litres and cost and it calcs consumption.
Other things ive noticed and measured:
AC makes negligible difference on a bigger motor. Not noticable on my utes. Used slighty more using AC on a forester, maybe .2l/100Lifting a 4wd hurts aerodynamics and therefore fuel on the highway, but not around town, up to 1l/100. Bigger tyres also make a difference, but the change in diameter also affects kms registered, so less than i calculated. Fitting a bullbar also cost more fuel, .5l/100 on highway. Increased approach angle is less effective aerodynamically the factory bumper sits lower and deflects air more effectively.
Never measured roof racks on vs off because I'm usually doing something else unusual (lots of highway or towing) and take the roof racks off when not in use.
Ahhh, yes, the pinnacle of automotive testing devices… the 2010 Kluger consumption read out.
O.P. trying to save cents. Cheers.
How dare you shame my thrift! You are a traitor to our cause!!
I work in a workshop with some very very expensive electronic equipment and have access to a dyno for the sole purpose of testing things like vehicle fuel consumption… but it’s good to be able to let the boss know we can replace all of that malarkey with a 2010 Kluger dash…
Put basically, if you don’t have access to the type of equipment you would find in a lab and controlled environment, your “figures” are not worth the display they are printed on.
You would need to run the test multiple times and within set parameters. Driving around from work to home and the shops is the exact opposite of a “fuel consumption test”.
OP, wait till you find out it’s the same fuel trucks filling different servos.
Ikr! That's what puzzles me.
Is it? Really? The same fuel truck fills BP and others? Really? Wow..
I seem to get 15-20% better mileage from BP than from Mobil/7-Eleven.
Sigh.
Something something declining education system.
No, but I prefer the taste of Shell.
You're gunna need Mythbusters bro. There's variables to the enth degree. From wind, to traffic,tyre wear,radio volume,lipstick load etc, etc
BTW: You should fit one of those cyclone things to your intake. Man! you'll never need to refill ever again.
Hiclone! Had to look it up, they are still around.
Hyclone? And no mention of the “fuel/energy polerizer” from everyone’s favourite race car driver and philanderer… Peter Brock.
15-20% better
Lmao
I get 13-14L/100,000km on Mobil, and 11-12 on BP. Sometimes 10-11! What's funny?
Hot damn, 13-14l per 100,000km, you should donate that bad boy to science.
What's funny?
It's not possible, and you didn't even hand calculate it.
My old car had the engine light on about 50% of the time. I always used to fill up with Ampol because it was convenient.
My mechanic said his machine told him it was due to slight misfiring sometimes and asked what fuel I use and suggested I switch to BP or Shell to see if it made a difference
I now always fill up with Shell and now only very occasionally see the engine light.
Coincidence???
It's an old problem and a legitimate question.

It's still common to find contaminated fuel in Australia, usually related to car damage.
Although there were changes designed to inhibit the practice, the regulatory system is not transparent and related information is not released to the public. There are no reports or data about that.

On a full tank, my car delivers 600 km with U98, 500 km with U91, and 400–450 km with E10, using 7/11 fuel and driving mostly in the city. I’ve noticed that fuel type makes a significant difference. Although my car is recommended to run on E10, I find its performance is best with U98. So, I usually fill up with U98 when it’s cheaper; otherwise, I opt for U91.
If AI tried to write a post to troll @pegaxs, this would be it :)
I just read it and though… ”JFC, not this shit again…”
It’s not even worth replying to any more…
Ironically, “username checks out”.
Here’s my recorded stats from my previous car (2.5L Mazda3 SP25) recorded over approx 70,000km.

My main takeaway was they’re much of a muchness.
The higher octane might have produced slightly better efficiency but not enough to cover the higher cost. I did feel a bit better throttle response but could’ve been a placebo.7-Eleven 95 seems to have the best mileage for you?
United 91 and 7-Eleven E10 seems to fair worst for you?
Yes but please take it with a grain of salt and see I didn’t use those fuel types for much mileage so they could also be outliers.
Note: to do this I would always fill up to full for every visit to the servo so I could record the distance travelled and fuel volume as accurately as possible.
When switching fuel types, I ran the previous tank reasonably low so the next fill could be majority of the new fuel type.
I logged all of this through the ‘Road Trip MPG’ iOS app.
Yes, because some pumps are broken and don't fill accurately.
I would wager that if you actually recorded km, litres and driving conditions/routes accurately, you'd find the difference in fuel consumption between these would be no where near this
