Default Re: Premium gas vs. regular: What's really better for your car? (CBC Marketplace)

Well, I am glad this poll was made.

As of now it sits at 75% use reg and 25% use premium.

And this is a poll done in a car forum where pretty much all of its members drive german cars that specify 93. And most of its members are also what we would classify as car aficionados.
Also, the lot of them probably are not in a financial situation where pinching to $0.20 a gallon would make a difference to their household economics.

Nonetheless, 75% uses Reg gas. I am sure that if this poll was made in any other non-german car forum the rate would be closer to 95%.

Proves my point. About +90% of cars sold in the US are going to get filled with regular gas, manufactures know that. Do you think that they gonna make a car engine that will get ruined if regular gasoline was poured in it?? especially since most have warranties for the engine to about 100k miles or at least 5 years?

According to Quora 6.1% of gas sales are premium.

Like 1015 rightfully said: go ahead and save a few cents, retard the timing, definitely nothing bad will happen.

OR you can use premium, advance the timing and get about 1.5% more hp . . . cos you know, to drive to work you gonna need all of them ponies your engine can eek out or you wont make it on time

Please reread the question in the poll.. People who voted regular did so on cars where the minimum octane rating for their vehicle is 87.
The majority of people would have voted for 91+ octane if their cars required it. Why not? Yes, I can most definitely tell the difference in performance between 87 and 93 octane fuel in high performance engines.

Excerpt from owners manual of my 2015 S550.

I just filled up my rental car last night, a Hyundai elentra with regular - first, let me say i drove nearly 300 miles from Tampa back to Miami and it was only $20 in gas (WTF?) Second, regular is 70 cents less per gallon ($2.29 vs. $2.99) - didnt realize there was such a difference. In my G wagon, I would save $14.00 per tank if it took regular. Guess ya gotta pay to be a pimp.

US sales of premium is 6% . . . do you think that only 6% of cars in the US require premium?
Also, it is a fact that you can make more hp with higher octane, so manufacturers of high end vehicles will tune their engines with 93 to make more hp and have better numbers on paper.
But the ECU will just remap and work just as fine with regular, except it'll make 2% less hp.

You are obviously a superb driver and can tell the difference. I guarantee you that its not a placebo effect. Or maybe it is.
But thats probably cos you track the car often, and its easier to tell on the track than driving down Old Georgetown road.

I guarantee you that if all gas stations in the US would put regular in their premium tanks and sell it as premium you'd be one of the only . . maybe . . 20 drivers in the US that would be able to tell that trickery happened.

Oh and about the excerpt of the manual. Most my manuals say to use only a specific brand of oil too, cos you know if you put castrol 10-30w instead of mobil1 10-30w your engine will probably seize or something . . right?

Yeah man, everytime I gas up with 93 I feel SO baller. I take selfies of me making it rain at the station paying that $0.70 a gallon and post that shlt up on worldstar yo!
Because ya gotta pay to be pimp!

No, there are many drivers of regular cars like Accords and Camrys who are putting premium fuel in their cars when they should not be. I am saying that most everyone here aside from you and maybe couple others would opt to put 87 octane fuel in their M3s.

and no, I'm just a regular guy who can tell the difference between premium and regular unleaded fuel in a high performance car.

I had never stated that using regular fuel would cause damage to the engine.

Yep, thats all I was saying too.

Regular fuel wont harm it, so why pay $14 more per tank? I doesnt make me feel pimp and I cant tell the difference.

Back in the days when I was trying to shave seconds off my lap times, I had a custom prepped engine tuned to run on 100 oct. It made sense for that application.

These days I just drive down the hwy and around town, my cars already make over 300hp, I dont feel the need to get that 1% "better performance" and I dont associate pumping premium to pimpin'.
So yeah, regular gas does the trick for me.

I'll state it then E. Using regular fuel in an engine that is designed for premium will damage your engine. chronically, not acutely. And I suspect that damage will build up quicker in a direct injection engine which relies more on the homogeneous charge.
And it doesn't take a car enthusiast to notice that pinging sound when going up a hill on a hot day or getting on the freeway. Sure, light loads and cooler weather, most people won't notice a difference of 280hp vs 300hp, but then again most of the time they are only using 100hp of the potential.

Is this for all cars? I'm pretty sure my father put regular in my Infiniti and it's been driving rough for the last couple weeks. I need the ECU to hurry up and realize the car's drinking the wrong juice because this choppy ride is driving me insane.

For my understanding, are you talking about using regular in an engine designed for regular or using regular in an engine designed for premium? This thread is regarding using regular in a regular engine, for which it shows almost everyone agrees is the right thing to do.
