Re: I got 35 mpg today on the 88 Si (91_hatch_si)
I got 425 miles on a tank of gas with my old DX motor once. Mostly highway miles...
With my B16 I've only gotten over 325 miles once...

Re: I got 35 mpg today on the 88 Si (SeaBass)
After buying my 89 CRX Si and driving it almost 750 miles home, I had gotten 42, 45, 39 for mi/gal. Most of that time was drafting the big trucks at 80-90 mph, but that counts too, right?
Drafting is so efficient.

Re: I got 35 mpg today on the 88 Si (sinful)
I got once 413 miles on my '88 HF before it crook on gas, lol. I did this to see how much I can get out of a the tank. The norm is around 385-400 per tank.
This is what 93 octane fuel, gutted out cat, high flowing exhaust, 13 VX wheels.
Hit 200,000 last month and doesn't burn no oil, car runs like a champ.

what???....
The fuel , reacting with O2 in charged air , makes the heat that creates cyl pressure that makes HP.
All the compresssion ratio does , is heats things up.
The fuels resistance to detonation its called its octane rating.
A gasolines resistance to detonation is knows as its antiknock rating or its octane value. The trick to making big HP is to getting the fuel vaporized. The rate fuel vaporizes is the key to how much power u can create.
Most people think that octane is an indication of how quickly or slowly fuel burns, that is not correct. The hydrocarbons used to make gasoline will oxydyze, or burn, at virtually the same rate, given the same conditions.
making more Hpm makes it easy for the engine to move the specific object at a constant speed for a period of time. The more power the engine makes, with the sam amount of fuel , will create less power loss, in wich will give u a better mileage.
another confusing concept about making power with gasoline it is energy or heat content.
what we need to talk about its releasing the energy in a specific amount of gas. The primary method of releasing the BTU content of gasoline is to vaporize it first> use gasoline with the highest "calorie" or BTU contebt per unit of measure that will vaporize in your engine with the ambient temperatures...
this is what tells us in ghetto words that higher octane gas, its cleaner and gets better mileage...

Re: (SecretAgent)
I've never bothered with testing it out in real life (too many variables) but my honest opinion from 7 years of full time driving experience is that 93 does not improve fuel economy whatsoever for a car designed to run on 87.
93 burns at a higher temperature, so engines designed to runon 93octane can take advantage of this and run higher compression...etc to extract more power. For cars designed to run on 87octane (95% of cars on the road) you will not see any performance gains because there simply isn't any more "power" in 93 than there is in 87. If anything, you should see some power loss and sluggish throttle response
As far as 93 burning cleaner, I thought that was just some lie the Gas companies tell to make you shell out the dough on premium unleaded for your shitbox Ford Festivaaaah

Re: (SeaBass)
A gallon of 87 has the same energy that 93 has if not more(the anti knock additives have less energy that gas) so unless you are getting ping from the 87 and no ping from the 93 you are wasting your money

Well, I know that all new vechicles are needed to have 93 octane to burn more effecietly, which is another topic.
But I experiment it with my '88 HF to prove one of my master tech of 15years that I did not think he was right. Well, I was wrong.
It was a mere 2 month experiment that I did this. He told me tried the 87 or lowest octane and keep a record for upcoming weeks. He suggested using Amoco or Shell gas. Why? He didn't argue but to tired it? After 3 weeks and 2 full tanks, I switch over to 93 but had the Chevron fuel treatment that he recommand to clean out. After a full tank with the fuel treatment gone, I re-fuel with just only 93 octane alone and tried it for 2 full tank full. Believe it or not, he 87 octane I was only able to get average of 325 a tank. Whereas the average for 93 octane was 375.
Now many agrue about this since this experiment I did became a hot topic where I work at. I guess I had over 50 techs going arguing about this. (I work at a supercenter dealership that house all Import dealerships in one lot, sorta sucks, lol)
A lot of the Nissan and Subaru tech concluded that the '88 HF was not designed to run 87, keep in mind that all pre-90's Honda was designed in JAPAN and built in Japan, not US like about 75% of all Hondas are now made.
Also, as one tech mention, Japan doesn't have 87 octane now nor did back then, I believe that someone of this board told me once it lowest is 93 octane available in Japan. Maybe it was designed for a 93 octane, I don't know. All I know, from what I experience (I thought the same way at first) that it did help alot.
Not that I'm saying your 7 years of knowlegde in cars is any differ than a 15 year Honda master tech that went to school for Honda is differ. But keep in mind, master tech can really impress you with what he knows through the years of training and on-hand experience.
If anything, give it a tried. I was in the same boat when I didn't believe.
Now keep in mind, I did this on the old car, the newer cars does affect with the 87 and 93 octane. I used to get complaints about people not getting enough gas mileage but finds out they used 87 rather than 93, newer cars does affect on this.
