My 14 Mustang GT can run both but it says if you don't run premium, the engine will not make it's full power so I run premium most of the time.
For the Arteon that link advice goes against everything in the manual and gas cap slash door.Should I Use Premium or Regular Gas for Volkswagen? | New VW
Wondering if you should use premium or regular gas for your Volkswagen? Our VW dealer near Waterbury, CT, will answer all your Volkswagen fuel intake questions.www.hartevw.com
We are lucky if they have enough gas to get them into the shop.That makes sense from a management perspective too, since it is a very small amount of money to avoid dissatisfied customers simply due to the wrong gas.
Do new cars arrive with a full tank, or does the dealer have to fill them up?
Well, if you are talking to sales……duh.For the Arteon that link advice goes against everything in the manual and gas cap slash door.
Even my dealership didn't know and gave nothing but bad info.
Yeah they know nothing of what they sell..Nothing...Well, if you are talking to sales……duh.

That engine is an Atkinson cycle engine. It holds the intake valve open while piston is rising on the intake stroke, reducing the intake charge. This reduces the amount of air/fuel being compressed, thus reducing the effective compression ratio. It allows a longer power or expansion stroke as a result, relative to the intake stroke.I'm quite sure that both of my new cars were delivered with full tanks of 87. I can't prove this of course, but after I filled my 5.7 HEMI V-8 with 91 Premium, it started faster, idled smoother, and had much better acceleration as well as fuel economy.
It was pretty much the same with my 2018 Toyota Camry, and it's 2.5 L A25A-FKS 4-Cylinder, along with it's 13:1 Compression Ratio. The manual for my HEMI say's it will run on 87, but with reduced performance and fuel economy. The computer simply detunes the engine so it won't knock. I always have run 91 Premium, and will continue to do so.
The same with my Toyota. I just can't see running 87 octane fuel in an engine with a 13:1 compression ratio. Especially considering there are some Diesels out there running 16:1.
Do you run the 89 with your 1500? I *think* mine has been doing ok with 87... don't hear any pinging and seems ok. I know it's only a recommendation per the manual.Anything with high compression will be upset if it is specifically spec'd for 91. My 6.4L's have all been, my bimmers have all been, and I'm sure my M5 wouldn't have been happy with regular. These are cars where it isn't recommended, rather, it states required.
I ran my Challenger RT on 87 and never an issue but I drive easy. I don't get on them.Do you run the 89 with your 1500? I *think* mine has been doing ok with 87... don't hear any pinging and seems ok. I know it's only a recommendation per the manual.
Every Hyundai turbo in the USA, even the Veloster N is speced for 87 octane. Hyundai does not have a very advanced sensing of octane. Timing is set for 87 octane and if the knock sensor hears it it pulls back. You can't rely on that sensor too much as I have heard detonation and had to pull back on my own because it did not pull back timing. I learned it is just better to run mid level as a bare minimum on a stock tune and you have no choice but premium with a tune. 90%-95% of the people on the Kona turbo forums run 87 octane.Turbo then premium, unless you never ever use more than a 1/4 pedal on the right pedal.
Sales people never talk to the the guys in the shop...
I use the torque band, but I don't mash it either.I ran my Challenger RT on 87 and never an issue but I drive easy. I don't get on them.
My Ford 7.3 PU. didn't like 87
Idled rough.
Because we usually buy gas at Costco, it typically gets 91. If we buy gas elsewhere, it gets 89 because that's what's recommended. The SRT doesn't give that kind of leeway, it's 91 minimum.Do you run the 89 with your 1500? I *think* mine has been doing ok with 87... don't hear any pinging and seems ok.

My 20 definitely runs better with 89 than 87. It is most noticeable in hot weather.Do you run the 89 with your 1500? I *think* mine has been doing ok with 87... don't hear any pinging and seems ok. I know it's only a recommendation per the manual.
I can’t tell the difference in mine between 87 and 89…. Even driving like an ape.Do you run the 89 with your 1500? I *think* mine has been doing ok with 87... don't hear any pinging and seems ok. I know it's only a recommendation per the manual.
