Wow the otherday i found arco gas for 2.99 and i didnt want to put it in because of the name but after i put that stuff in i got an increase in gas mileage! I normall get around 30mpg mixed but this time i got 34.4 mpg. Bye bye shell/76

 

I use the cheapest **** the station has, and i get 35 on average per tank..... although i drive a crx, its got the A6 in it.... dont know but i think my mileage is pretty good

 

i use to use Ultra94 at Sunoco, but i had a b16 in there.

 

does it really matter which gas station you get your gas from anyway? like i mean the different names like arco the thrify shell and so on?

 

I use a higher octane gas, either plus or premium because I think the last time I checked the manual it said to use 93 octane gas so I just randomly decided to do that. One thing is that I noticed that after I started using higher octane gas my gas mileage actually increased! I was shocked. It wasn't a HUGE amount but enough to probabaly make it worth it.

I don't go to ARCO they are said to use 10% ethanol in their gas. I would rather pay a couple cents more for real better gas. Although I am sure that all stations use a small percent of ethanol I am sure it isn't 10%. My mom took her car to ARCO all the time, now her gas gauge doesn't work. I think the float in it went bad, and I have heard this is from sulfer in the gas, she always went to ARCO so I blame them. Oh well.

If you do the math, if gas prices never changed say you filled up twice a month.

Going to station A at 2.98 per gallon you would spend $851.088 a year

Going to station B at 3.03 per gallon you would spend $865.368 a year

Is that less than 15 dollar different really worth risking it. I don't even thinkg that really matters if you are only spending 15 dollars more a year.

I have also read the ARCO gas burns faster, maybe due to the ethanol? I dunno.


There is my 2 cents.

 

I use cheap-**** gas. I tinkered a while back...wait a minute..

Car is bone-stock 1991 Honda Civic Hatch DX
Engine is D15B2
Transmission is 5spd cable
Mileage is circa 260K
Car is lowered about 2inches all the way around
I think that's all that will actually matter in the way of my gas mileage

I tinkered a while back using midgrade, premium and low-grade for several tanks (allowing the engine to adjust itself to the different octanes) I found that at MOST I got maybe 3-5mpg difference between the low and midgrade. The premium usually seemed to have LESS gas mileage than both.

However, I know that the higher grades burn CLEANER. So my advice is if you're gonna be on the highway, use a tank of PREMIUM...then lowgrade after that.

For normal city driving...just use lowgrade. Save your money...what...2.00$ a tank?

As for companies...many people prefer certain companies due to their origin. I don't know them all, but this is what I DO know:

Chevron: Domestic
BP: British Petroleum...I'm sure you can figure where this is frong
Shell: English
Quicktrip: Private owned, I believe it's domestic

I also do know that BP uses "clear" gasoline...usually burns better for the sniffer test, and causes less deposits on the valves...same with Shells "plus" gas, or Chevron's "Techron".

Hope this helps.

My bottom line advice...use the cheap gas, and it doesn't really matter wher eyou get it. You don't NEED anything beyond cheap gas unless you're building and engine that requires it. If you're gonna hit the highway...go ahead and throw in a tank of premium.

 

amoco or chevron 93 ron

 

sunoco 94 octane ,, but recently been using 93 octane luke gas(sp?) its new gas station in nj replacing the mobil

 

I use 87 the cheap crap. I get 35-40mpg. It is also the stock 1.5DP.

 

Only Gas i pump is.

Chevron 91 Oct

 

I USED to use 91 octane from tesoro, who used to be amocco, on my 88 rex si, but on my 91 I'm using 91 from chevron, I think tesoro robs you a little

 

If you don't need to use higher octane gas then don't. You're just wasting money. Use the lowest possbile octane that you can without detonating. You guys with D15's/D16's with stock blocks shouldn't need anything more than 87.

Also, gasohol (gas with ethanol) is all we can get here in Delaware. I thought it was a nationwide thing but I guess not yet. I had no effects from it and it is perfectly safe. I can still get an avg of 35 mpg with my set-up.

 

I'll be running Sunocco 94 in my K swap. I run 87 cheap **** in my Z6 beater. I used to run Cam2 110 in my crx, but now I'm going to be using a more stock configuration.

Absolutely correct. I have the zc single slammer, and it just loves the cheapest **** I can pump into it. It runs better and gets better mileage on 85 (Im high altitude) than on 91 or higher.

its all about detonation on a daily driven street car. plus, the lower the octane, the more complete the burn is in the time the gas has to ignite.

 

E10 is now mandated to be in all gas, I believe, so you really need not worry about that. Brand difference has never been noticed by me and I monitor mileage meticulously.

50mpg crx dx/hf tranny.

 

When Texaco was still around where I lived, I would use 92 Octane Texaco (11.2:1 C/R LS-VTEC)... Now I use 93 Octane Shell

Shell is the worst gas. It has a ton of additives.

 

i think the manual says to use 86 octane for the dx, i just go to conoco, and i am aware that gas station the have a dramatically lower price then the other gas station use ethanol im not sure how much, but it really messes with you fuel system, we had to replace a fuel pump, regualotor and the peice for the guage reading because of it

 

But how many miles are on your car? Is it possible it just went out with age? I've got 261K on my 91 as stated earlier. I've been through 2 fuel relays, a fuel filter, and a set of plugs, and two cat converters...but the converters with Autozone's lifetime warranty, and the plugs were at least 60K miles old. I've had the car since it rolled 183K.

I wish instead of "quote" it would say "[TRUTH][/TRUTH]"

 

93 octane all day every day and i get abt 250 to a tank of driving hard

If this were the case all of the auto manufacturers would not certify it as 100% warranty compatible and the government would not mandate it's use, unless you think it's a conspiracy cooked up by the corn farmers.

 

you know must of you don't need that higher octane you pour in right?

I have a n/a lsvtec so I use 93.

Knock sensors are for wusses

 

what is ethanol? and what does it do to the car?

in the bay area we dont have sunuco or mobile gas station, its mainly shell, 76, chevron, arco


my car has used 76 alll of its life, it never had any problems with fuel related parts. i hope it wont start now with arco...

 

Ethanol is fuel made out of corn that is of a much higher octane but doesn't do anything to the car besides power it.

Why is that bad? The additives can help to keep your engine clean on the inside. Additives are for the most part, good for your engine. Especially on a long term basis. If you consistantly use a "good brand" gas over a long period of time then you will most likely have a "cleaner" healthier motor than using a non additive fuel. I can't say how much cleaner, but there isn't anything wrong additives, except that it might cost a little more. I like Shell and Sunoco, but will put anything in if I have too.
