Should premium gas be used for GV70?

[John Baxter]

............... premium gasoline is a sacrifice I'm willing to make at the expense of engine performance.

And the warranty refusals if Genesis decide you didn't follow the manufacturers recommendations.

Just cross your fingers you have no engine issues for 5yrs...

I'm sure Genesis will find a way to deny your warranty claim if you haven't followed factory advice.

This is absolute nonsense. The manual makes it very clear that using below 91 may result in loss of power and increase fuel consumption. Below this section they explicitly discuss things that may void the warranty, such as damage to the fuel system from using 85% ethanol. If using 89 damaged the vehicle and was required, that language would be used. Where is the Ministry of Misinformation when you need it!?!?

So you are following the explicit manufacturers recommendation then??

Pretty sure that's what I said.

Follow precisely what Genesis recommends as the fuel type for your car and you will have no warranty issues, should, they arise.

Pretty simple stuff.

You are unecessarily/prematurely implying that failure to follow a recommendation (but not an explicit requirement of the warranty) will void the warranty. There is not evidence that this should be the case in any documentation you or anyone else has provided. Period. Of unrelated note, the manual also recommends to follow the speed limit (to avoid death, not to keep from voiding the warranty). In no place does it recommend using 91 octane fuel to keep from voiding the warranty. It does have other requirements to not void the warranty, namely to not use E85 fuel. I would like you to show me specifically where it voids the warranty if you use 89 Octane gas. Pretty simple stuff, huh?

In addition, if you pointed me to an area of the warranty that said you are required to use 91+ octane the same way many warranties say "you need to follow the recommended maintenance schedule to not void the warranty" then I would tend to agree with you. However, you have not provided such language.

Incredibly so, that's why I'm at a loss why you are struggling.

If you use the recommended fuel, as set out in the manual.. you will have zero chance of any warranty arguments with your 'friendly' dealer staff.

I'm strug-g-l-ing soooo hard, John. Thank you so much for enlightening all of us. Do you follow all of the recommendations in the owner's manual so you have "zero chance" of any "warranty arguments"? If so, you seem like the kind of person who has little help to offer most people on this forum who are looking for practical tradeoff recommendations instead of robotic platitudes.

Yes, that's apparent.

Good luck.

Ha ha...yes, this is a touchy subject for a lot of people for some reason - I see this continually on many forums - guess what? Nobody has landed on any long-term decisions or persuaded anyone to switch to/from regular/premium so far!

As long as Premium is recommended and not required, everybody has the latitude to make their own decisions without impacting the warranty. So...let's just make our own decisions on that front and move on!

 

[GV70@75]

I always go by the fuel door....as for effecting warranty I tend to abide by manufacturers guidelines so nothing is in question. That's just me. Know what? I miss the 60's ...$.25 a gal. Take me back.

I have not noticed any significant difference in using Regular or Premium in my GV70 . I do however use a top tier gas .

Funny the gasoline commercials talk about the cleaning benefits of premium. Why it’s more profitable . Now if you thinks it’s worth it and can afford it by all means buy premium . A top tier regular is safe for the GV70.

I will always use premium in a performance vehicle, whether it's required or if it's just recommended, but that's just me. I know these vehicles are smart enough to retard timing with lower octane, but I came from having an Eagle Talon that was tuned and had constant knock on 87, and more recently a WRX that are notoriously terrible on 87.

If you have no issues running on 87 and you're not trying to squeeze out every horse then feel free to run 87. If you absolutely need to save the few dollars a fill up you probably shouldn't be trying to pay for a Genesis anyway.

With my JB4 I don't really have a choice anyway, 91+ only. My thoughts may change a little now that I drive almost 150 miles a day, but again, what's an extra $5 a week in gas when you can afford a $70k vehicle? I'm lucky enough to get a $20 a day stipend for gas from my company since I'm so far, anyway.

What do you consider top tier gas? Based on specific gas stations...?

Does pre-ignition ever occur from low octane like older cars did.

Idk if they have it in Canadia, but in the US we have an actual sticker on gas pumps that says "top tier detergent gasoline". It's not brand specific, but you're more likely to find it on a bigger brand, like Holiday, BP, or Shell. I hope they don't mean Shell V-Power, however, that's just snake oil.

On our cars? I doubt it, they're smart enough to retard timing enough on lower octane to prevent it, though I can't speak from experience.

I think you might be referring to detonation (engine ping) and not pre-ignition. They are two different things with pre=ignition being a far more serious problem. The engine can't detect what octane level the gas is so it uses a knock sensor to detect detonation which in turn will retard the ignition timing.

Yes …engine ping. Thanks for clarifying.
