Can mix 93 octane and 89 octane make 91, I can or not?

[StageLeft]

If to mix the 93 with a 89 division says 91 this good?

--------

OK sorry, but really can a person mix 93 and 89 octane rated fuel for an effective mixture of 91? Millennium maintains that this cannot be done but I can't remember what he said about it. I find it difficult to find a 91 although 89 and 93 are prevalent, and my car needs only 91 so I don't like to waste the cash!

Nah, suck it up Skoorbie and use the real thing. I do!

 

[FrustratedUser]

No, your engine will blow up very soon.

 

[isasir]

There was a thread here on this a few months ago. I think the answer was 'Yes' it is the equivalent of the mix.

 

[CraigRT]

Just buy the high octane

but yes, if you mix the gas you will get the proper balance.

 

[woodie1]

It must work since that is what the oil companies do.

I agree. I don't want to take chances.

Yeah, the fake way you're thinking about it now is all wrong.

Regardless of whether or not it can be done, think about how you would practically do this. You'd either (1) Fill up two gas cans with the gas and fill your car at home or (2) try and estimate how much gas you need at the station and then put half of each type in, putting your credit card in twice. Seems like a lot of work for saving maybe a dollar a trip.

I'm a frigging cheapskate! I can generally estimate how many gallons are left. If I think there is no more than 10 free in the tank I'd put in the 93 first, and over-estimate, so that if I'm off the mixture is a tad over 91. It really wouldn't be too much of a hassel to save like $.70/fillup.

You are making yourself look like a fool you know.....

adding Coca-Cola to his tank..well

 

[PsychoAndy]

Last time I checked....no you cant. Just go for a long drive and buy 91 next time.

You should have bought a Diesel Skoorb

Yes, if you mix the gasoline in equal proportions.

 

[Demon-Xanth]

Since the gasoline only differs by the octane additive, yes it will mix. However, it may take time to fully mix. Oil on the other hand, just ends up being a half and half mixture and doesn't become homogenous.

 

[notfred]

Your car takes premium gas, put premium gas in it. It says 91 cause that's what premium is in california.

Really, how fvcking cheap are you? You'er willing to go through the hassle of estimating the remaining fuel and making two purchases at the gas station instead of 1 every week s othat you can save what? about $2-3/month on gas? Who really gives a sh!t about $2/month?

Where did you hear this ?

I, on a regular basis mix 80-90 w gear oil with 90-110 w gear oil.
They mix just fine.

 

[isekii]

just buy higher Octane fuel..

it'll be better for your engine in the long run and youl'l prolly get better gas mileage..

my car requires 91 or 93 i dont remember which.. I just get the best one possible..

 

[LAUST]

What kind of car are we talking about here?

To make sure everyone knows all higher octaine is good for is a higher flash rating, if your car is only 8.5:1 compression you are throwing your money away, heck I think even 9.4:1 still only asks for 87 octaine.

edit.. NM lookin at your sig Maxima.... wow 10:1 in those... thats where those output numbers come from... no forced induction for you

As mean as it sounds.... I agree.
any gas station I go to, I get the highest octane... it's a buck or 2 MAX per fill. and it's suppose to be used. Sunoco I get 94, Esso 92, Pioneer 93, Shell (shudder) 91.

my dads 2000 likes at least 89 octane, but I usually put 91 in it.

I drive like 30k/year. Saving money here lets me by furniture there. Anyway it wouldn't be two purchases. It would be two individual pumpings.

I don't know the specifics on the maxima, but I'm going to assume some things:
you get 20 miles per gallon.
midgrade costs $0.10/gal more than regular, and premium costs $0.10 more than midgrade.

you drive $30k miles.

That's 1500 gallons at 20mpg (which is probably much less than you get)

Now, only half of that is going to count, since we're only changing prices on half the gas. We've got 750 gallons, at $0.10/gallon.

So, if your car only gets 20mpg, you're going to save $75/year. $50/year is more accurate.

Since you want to use the money you saved to buy furniture, It'll only take about 15 years of saving your leftover gas money to buy a decent sofa.

And where do you live that the gas pump doesn't automatically complete your purchase when you put the nozzle back on the pump?
Put in card, take nozzle, fill car, return nozzle, card is charged. It doesn't assume you're going to use a second nozzle to continue filling the car.

Hey, stick that into a long term investment account and half my first kid's college is covered!

I can see your son now...

"dad, can I have a Bicycle?"

"well son, we have to save for the sofa fund, so you can have half a bicycle, and half a pair of roller skates."
