hey guys

just want to know what the highest reported mpg that a hf owner has achieved? tuned or untuned. thanks

 

I've heard of 60mpg.

 

I have an 88HF and 91HF both completely stock. My best is 58 mpg in the 88 and 53 in the 91. I don't windmill or anything, just gentle driving.

 

I get 43 on my HF...

 

I understand the hf engine is a leanburn motor?

Has there been a benefit on further tuning the hf engine for a leaner condition? If not a lean tune, any tune that produces more mpg? Thanks

 

I don't know about the lean tune. But I have achieved a 64.1 Mpg on a recent trip south. And if I was to wrap my wheels in Goodyear Fuelmax tires and run non-ethanol gas I know I could probably achieve close to 70.

The entire trip south and back was a little over 500 miles. I know cause I didn't fill up my tank until I got back and it was a little over 500 miles on one tank. Also I was trying to coast as much as possible, and I drove 55 mph the entire way. It's really fun to **** off people trying to go 70 but then they gotta hit their brakes cause I am in the way.

But I have not extensively tested the non-ethanol gas in my crx with a long road trip. But in my Kia, that I have wrapped in Goodyear fuelmax tires, and that I am now running ethanol free gas, I have seen my MPGs rise from ~29-30 to 32-33 mpgs.

 

I got 55 MPG here in florida on the intersate. My HF back then had a D16Y7 with a DX transmission and HF fifth gear. It also had an IHI RHB5 turbo at 6 psi making 150 HP and 155 lb/ft. I think I could have gotten more MPG since I was doing around 70 MPH the whole time.

 

wowzers i needa start driving like a.grandma gas prices are getting crazy

 

If its the d15b2 motor, if its the original motor, it def will be that motor, depending on if its got a tune up... and how you drive it...between 45 and 60/gallon highway.

 

the D15B2 was the DX engine. The D15B6 was the HF engine.

 

I'll make you feel better, in the UK we are paying $10.12 per gallon at the moment

 

I always hear that in Europe the gas prices are higher. But many many people in the countries of Europe don't even own a car. I have a friend over there and she told me so many people take the bus/train it is ridiculous. She doesn't even own a car. Americans unfortunately have been taught since we were very young that everybody needed their own car. Our entire countries infrastructure has been built on the 1 car-1 person ideology. We have no trains/buses or any kind of metro system.

 

Well I have 3 cars, and the majority of people down my street own at least one. Yes we have tubes and buses etc but only comprehensively in the city like the metro system in NY for example. Out in the sticks people rely on their cars just as much as you guys do, some of them are life lines for old people and the like who live in the country to get to the shops and get out and live life as in reality the one bus that may pass through their village may be a good few miles walk to get to the bus stop and not even go exactly where they wanted to get to anyway.

So its pretty much the same I'd say, just a bit smaller

 

I have gotten 65-68....staying at 60 -65mph

 

Made me LOL!
It's 'hyermiling'.... windmilling - lol!

 

The first CRX I was ever around was an 84 my boss owned. It was a 1300 motor with a 4 speed back then. He claimed 64 mpg with it.

I have an 87 HF that I calculated 57.62 with recently on a trip. (sticker on the window new was 52 city and 57 highway. (with the wind behind me I've gotten 60)

Have had a 90 to use some in the past and the sticker off it was 52 city and 55 highway. (it's fuel injected)

The 87 was the last built in Japan and the 90 and later was built in Marysville, Ohio. The 87 specified 90 octane fuel if I remember right.

(I guess you'd have to buy 5 gallons of 87 octane and 5 gallons of 93 octane
to have the 90 octane fuel...I notice my valves really rattle on 87 octane)

 

My dad had an 84 HF and he achieved 67mpg from Pennsylvania to Louisiana

 

perfect commuter car!

 

This thread made me glad I never sold my HF.

 

It's sort of a vicious cycle though. It's not like we're going to stop buying cars and wait for passenger rail to develop. Commercial rail in the US isn't even that great.

 

Did you mean "hypermiling"?

In regards to gas prices... Don't think for one second getting better gas milage will do anything. I have been around long enough to know this - the more they will require gas milage to go up (just like they are doing now) the higher the prices will get. You can put money on that one...

 

On the gas mileage subject... can anyone tell me what a fresh B series LS engine and 5 speed OBD0 or 1 will achieve city and highway... current D series is great around city (30-33) but sucks on the highway ( 36 ) in a sedan LX [90]... so why not swap if the mileage is close....I've been told the D series used to be great on fuel but now that gas is junked down with ethanol...mileage is off by probably 20% from days gone by.... amazing how they swear they want cars that are efficient but they continue to trash the fuel, cheapen it with freakin' corn but it's GREEN you know.... in 1991, during the 1st Iraq war... refinery companies said they could produce a high quality, low sulfur fuel from coal for about $2.00 a gallon and it would be GREEN... so with inflation...if it would cost $3 a gallon today....where is it?...and that was factoring in fuel taxes...
