Fuel Recommendations

  

sir_nasty -> Fuel Recommendations (3/9/2006 5:47:15 PM)

I know there was just recently a post similar to this one but I believe it was in referance to a 2006 V6 Accord so I didn't know if it was really applicable. Normally I just do the hit and miss type of selection for fuel by trying one at a time but I was curious about other peoples suggestions.

I live in BFE so my choice of fuel stations is limited... I've been using the 87 octane but what does Honda call for in a 94 Accord EX? Should I try some more expensive stuff for the F22 engine w/ Manual Tranny?

The manual should say 87 octane fuel should be used on your car. But there would be no real benifit of using a higher octane

lightshow -> RE: Fuel Recommendations (3/10/2006 12:19:09 AM)

your manual does call for 87 but i feel exactly the opposite of marbro. i think to start with, there is a more expensive detergent and additive package in premium fuel which will keep your fuel system, injectors, valves, and combustion chambers drastically cleaner when used over a decent period of time. also, your computer is intelligent. it can tell when you are loafin around and want to save fuel and it can tell when you want to get from point a to point b in the shortest period of time. the difference between optimal fuel efficiency and maximum power is timing, and there is only a certain amount of timing that you can run before detonation becomes present. the higher the octane fuel that you run, the more timing that can be run. make no mistake though your car will run just fine with regular fuel your car doesnt need it. and directly because of what i just said, you car will actually get better gas mileage with lower octane fuel.

That's kind of what I have always thought but for "squeeks and giggles" I put in 89 yesterday and guess what!? No noteable difference... however my plugs and wires may need changed....

accord4sroy -> RE: Fuel Recommendations (3/10/2006 11:27:42 AM)

i put 89 since out here where i live its the cheapest, usually i go with the 87 that doesn't have ethanol in it. anyways, i noticed that with the 89 there was a good response. so, lightshow makes a great point about octane! however, i think ethanol isn't good for engines. they should just put some other additive in gas. i know that in other cities they are using it in all three grades with like 10%.

that's my two cents on fuel. at least out in the east and west you guys can put quality fuel. i feel out here in the midwest we are short changed a little.

marbro -> RE: Fuel Recommendations (3/10/2006 11:33:31 AM)

There shouldnt really be any extra additives unless the gas station says otherwise. Thats part of the reason why I wish there were chevrons in the area. ^_^ If the fuel is burnt completely the force of the combustion should also help clean the valves, the dome and the pistons. In terms of actual performance going to a higher octane wont do anything for him.

Maimster -> RE: Fuel Recommendations (3/10/2006 11:39:34 AM)

I seem to switch up and both however I feel no real difference. My pocket does however.

accord4sroy -> RE: Fuel Recommendations (3/10/2006 12:06:10 PM)

yeah, i hear chevron is really good. its mostly out west especially california they say. i like mobil, shell, and bp. i would prefer mobil and shell but there are none really out here where i live.

RTexasF -> RE: Fuel Recommendations (3/13/2006 7:52:36 AM)

The higher octane fuels may contain a bit more detergent additives but the extra octane points don't do squat for a car designed for 87. At each oil change put a large bottle of Techron in the tank and fill it up. Buying premium fuel all the time for the barely measurable amount of additional additive is not healthy for your wallet......the engine doesn't benefit either.

Sendal -> RE: Fuel Recommendations (5/27/2006 5:34:58 AM)

I am usualy fill up my tank when near empty .. I put 3 times on regular and 1 time with high octane.

BMW97 -> RE: Fuel Recommendations (5/27/2006 6:14:38 AM)

go buy gas from your local airport for 10 bucks a gallon : )

19Accord97 -> RE: Fuel Recommendations (5/28/2006 1:23:41 AM)

Hey Sendal
I wouldn't recommend letting your gas go below a 1/4 of a tank because this makes your fuel pump run warmer than average. The fuel is what keeps it cool. I try to keep mine around half at minimum.
As for fuel, I try to stick with BP, Shell, and Mobil. I also think that the premium Shell gas does have better detergents...don't they call it V-power or something like that?

benjiaccord -> RE: Fuel Recommendations (5/28/2006 1:58:31 AM)

I agree with some and others i don't, with 87 octane in my 94 EX when vtec kicks in, i can hear it but don't feel it. Now if I am running 92 octane, or 93 if I shop at mobil, i can feel the difference. I do however have intake, header, exhaust that could attribute to being able to fell it with better octane.

I disagree that higher octane doesn't do anything. The difference is, that the higher octane at the pump doesn't do much difference. Look at anybody's power readouts on a tuned engine. At pump gas you make x amount of hp and torque, you put 98 or higher octane and the jump is amazing. However, your normal engine wouldn't like this too much is my guess. Thats why I say tuned engines. Anyways, thats why you see the funny cars and stuff all run on race gas, or airport gas, or pure nitro. Its all higher octane stuff, the higher the octane the easier the burn, don't believe me? Try and light malibu rum on fire, not going to happen, now light everclear on fire!! Poof, everclear gone, why? Higher octane, or in this case alcohol percentage but you get the point.

YeuEmMaiMai -> RE: Fuel Recommendations (5/29/2006 1:21:43 PM)

these are the facts:

1. ALL Accords prior to 2003 model year will not make use of higher octane fuel since the ECU does not have the means to adjust the timing based upon octane

2. ALL 6th gen V6 accords make LESS power when you use higher octane fuel (refer to C&D Nov 01 issue) you will loose 4whp and it will add .5sec to your 0-60 times due to the loss of 15ft/lbs of torqe in the low-mid rpm range. This V6 lacks a knock sensor so the engine is tuned very conservatively.

3. 7th gen accords will add 10hp/torque when you run on 91 octane fuel. It takes about 2 tanks before the full effect is noticed.


If your car runs better on higher octane fuel, you need to find the problem and fix it. End of story. Don't waste your cash on higher octane fuel unless you get your ECU retunned to run on higher octane fuel.

That is only true of the V-6 according to Honda engine designer Asaki. The four cylinder 2.4l performance is not enhanced by higher octane and it can actually retard performance.
We're talking stock engines here not dragsters.

Quote:

"The Accord V-6 ratings assume regular-grade fuel, and Honda will market it as a regular-fuel engine. But — pssst — it's good for another 10 hp and 10-plus lbs.-ft. on premium, acknowledges V-6 engineer Asaki."
