This is correct. Why don't you take your ministrations to this forum where there are some guys that, you know, actually drag race... giggle.

 

Sure, let's talk about racing engines and aircraft engines, because those are, you know, just like the economy engine Honda built for the Fit.

Again, can you show how there's RELEVANT improvement in using premium fuel in an engine designed for regular? Or just more insults? If you can power your car on insults go right ahead, mine runs on gasoline.

 

Save your giggles little boy I'm a 33 time NHRA class champion. LOL

And your boys are as ignorant as you but at least one knows what he is talking about Post #8

Sound FAMILIAR the EXACT same thing I posted some posts back

I believe you are correct... and if your car is computer controlled it will advance the timing gradually after a tank or two when it does not see detonation resulting in increased mileage proving your statement even though your compression ratio does not dictate higher octane. I was told years ago that you get the best power when your engine is always just short of detonation but does not detonate. Just my opinion on the subject.....





And another answer LOL thanks for proving my point with your site post 13

My 427sbc lost 5hp and 7tq when I went from 110 octane to 93 octane, we checked multiple plugs after pulls, nothing idicated detonation in the dyno rooms good spring air environment, so I was more than happy to NOT buy racing gas and just remove my subwoofer box if I really wanted to regain that 5hp/7tq back by weight reduction LOL.

 

AH Dude if you knew WTF you were talking about you would already KNOW that EVERY internal combustion 4 stroke engine operates in the same way, including,race,avation,and Fit engines.

Like I said get some knowledge and these things are SIMPLE and obvious to anyone that has had training in even the basics which you do not have.

Do your own research instead of wanting others to explain it over and over to you.

This basic theory taught in the very first weeks of any mechanics program or text books try reading some.

MAYBE if you drop the "know it all attitude" (when you clearly don't) others would be more willing to put up with your ignorant demands and try and explain what you don't understand.

 

Link please.

ahhh, now we're back to talking about computer controlled daily drivers. ok.

 

Come back for the first time in what feels like months and am immediately reminded why I don't visit anymore.

Sorry to those who have PM'd in my absence for services.

To the rest of you tards: Stay slow my friends.

 

Aaaanyway, I run regular. I do a lot of highway driving and have been averaging just above 39MPG (at 70-75MPH). I may try to run premium for a month to see if there is any difference, but I really doubt it.

 

Welcome back!.... Not much has changed

Check out the other thread with the GE Dyno pull...

 

Aw man, that's just bad timing, I haven't seen one of these threads since before you left

 

ALLLLLLL of you guys are IDIOTS....WOW. Ok kids grab your sippy cup and listen to someone who knows what they are talking about. Go to autozone, buy up all of the octane booster you can. Dump that gold DIRECTLY into EVERY orifice your car has. I'm talking gas tank, oil, power steering fluid, brake light fluid. As science will tell you, you now have a Chevy Viper powered civic....

In all seriousness I use regular and do a lot of highway driving. As long as conditions are good I get around high 30s to 40ish. My family actually had a debate about brands of gasoline, not octane. My argument was the brands were pretty much the same except for the detergent.

 

Yeah, my know-it-all attitude so far has consisted of asking questions (and one comment about aviation engines, something I do know something about) and getting rude responses in return, yet no actual data. So I'll try this again:

I understand that changes in timing (which are brought about by the computer when it senses different fuel) may affect engine performance to some degree. How about providing some information as to how much? Because obviously if the Fit's engine got 10 more HP or 3 more MPG don't you think Honda would bother to mention it?

Because repeatedly saying that engines designed for higher-octane fuel do better with higher-octane fuel really is only saying that the Fit will do better on 87 than 85. We know that.

 

Here's the only post with any empirical evidence to speak of. visual-aids mine.

This didn't get the respect it deserved a couple pages back. Sorry.

 

 

Dude how about you do your own research and get your own data.

Install scan gauge, go to your favorite fuel station fill your tank with 87, drive to empty, calculate your own fuel mileage.

Take to dyno and record the results. Repeat using 93 after one extra tank of 93 to insure it is burning 93 compare results PAY for dyno again.

Then you would have all the data you want us to provide.

 

And now you know why nobody even knew you were gone.

 

Dude we adults are having a nice discussion here. If you don't have anything intelligent to add ..well you know the rest. Like I have told Brian if you can't follow the discussion some education would help immensely.

 

Dude do you think EVERYTHING is online??? Is the web your ONLY source?

If you are that eager for information drive to Lebanon Valley Dragway (look it up online LOL), spend countless hours going through all their handwritten records since they have been open, correlate all the results for every class, determine which car won class eliminator 33 times and you will have your info and be out of our hair for a nice long time.

ps: a hint if you come across the name Joe Stella that is not me he has a few more wins then me and was my nemesis for Stock Eliminator every darn week. He is the only person I never won against.

 

You're the guy saying it's obvious, it's evident, there's all this data...
Yet there isn't any. There's only every technical source (Honda, EPA, etc.) saying use 87, period.

Actually a couple of years ago I suggested that since it's almost impossible to have enough controlled conditions to compare mileage when changing fuel using one car, how about we do a test? I asked if anybody in the area with a Fit Sport AT wanted to run a test- we take two cars, one with regular, one with premium, drive under identical conditions, compute mileage, then swap fuels and do it all over again. That's really about the best way to see what works.

Got no takers.

By the way, you can determine HP on a dynamometer but it's not the same as under load conditions when there's a ton of wind resistance like actual driving.

Oh, and my name isn't Brian.

 

LOL red herrings again. DUDE you have a user name as Brian posting a website with the same name but you expect us to know by magic or something that isn't your name???? ROFLMAO pray tell what is your name????

There is data if you want to find it but you expect everybody else to find it for you. And talking about a contrary personality .............

By the way, you can determine HP on a dynamometer but it's not the same as under load conditions when there's a ton of wind resistance like actual driving.


ROFLMAO a dyno is not good enough for you?????? We will never satisfy your endless quest for useless drivel.

And I really really can see why no one would want to hang out with you during testing.

 

Read it again. It says B R A I N, not B R I A N.

It doesn't surprise me you misread that word.

I'm not saying I don't trust a dyno, just that conditions are different from driving. The C&D article someone referenced explains it. Just like I said, you can determine HP but it's not the same as on the road.

My name is Shaun. And you clearly don't actually know what a red herring is.

I'm done. Keep posting your insults and "go look it up" stuff and someone else can read it and laugh at you. I've kept an open mind, unlike others on this site, and I've asked for evidence, and all I get is "It's there, but I can't provide it, but I swear, it's there, you're an idiot for not finding it." What I find is Honda, the EPA, other experts all saying use 87. Even the oil companies got in trouble for implying that using higher octane than recommended was somehow an improvement.

I own stock in a couple of oil companies and they make more money on the higher-octane stuff, so by all means keep buying it. While you're at it, smoke some cigarettes, I own stock in a tobacco company too.
