What gas do you use??? this is the delema!
 

hey guys,

i own a 2000 SIR, now the minimum requirement is 91 octane!
i use 91 and up of course according to the specs!

but using this high octane fuel has come to my believe that starting your car in cold weather, it takes it a while instead of starting up right away!

i was talkin with a buddy at work.... he noticed the same thing too on his Integra, until he jumped into 87 octane!

now his car starts like nothing in cold, but when using 91 and up it would take a few seconds to start with the car struggling to come on!

anyone encounter this???

as well, i also noticed im not getting a good tank of gas, im getting a AVG of 400kms to a tank and thats driving the car 30kms to work......... if i were to run 87 octane would i get beter gas mileage then a 93, b/c it doesnt burn as well as 87???

anyone!
thanks!

I have the same thing going on with my car.
I use Ultra94 and car takes its time to start-up; especially in cold mornings.

However, the engine responce and the top end power is "MUCH" better than lower octane gas. I used 1 tank of 87 say about a month ago (after 2 years of 94) and the car was NOTICEABLY moving and accelerating slower. It also took a longer time for each gear to redline. To be brief, the car was moving like an A$$.

So then I went back to 94. Gas milage isn't that impressive. I guess as the performance improves with higher octane fuels, you tend to step on it a bit more. See, all the high revs and frequent shiftings burn a lot of gas; therefore, I believe lower gas milage has to do with the driving style and your habbits.:thumbup:

I for instance, have to visit Sunoco every other day, since I burn half a tank each 2 days (And I don't even put that many Kms on the car). However, I have alot of fun with this fuel.

Let me introduce my best new friends, Snow and the hand brake!! All we need to make love is an empty parking lot, after midnight, when no-one is around to see us!! :drivesafe

oh buddy i know what u mean about going into parking lots!

the only things is i cant gain control of my car which i usually can, the michelin XGT's make me slide like 180 degrees instead of a drifting pattern to correct my spin!

the hard starts are normal in winter... cars like to run rich in the winter, so it takes a few extra cranks to get enough gas in there to fire up.

plus, high octane is less volatile than low octane gas, so it's harder to light up.

however, the hard starts are a low price to pay to prevent detonation and ping. Esp given the cold weather, your car is very prone to pinging under load, and given the icy conditions, I bet you lug it in 4th gear around the city doing like 60 km/h. Those are the conditions that will kill an engine. Cold+load+low octane+loud music = blown up B16A.

There is a knock sensor in the engine, but I'm not sure how much ignition it can take out. Anyways, STICK TO WHAT THE MANUAL RECOMMENDS, and use always!!!! Sunoco fuel.

I have the same problem with my SiR. Bruno when should we be shifting to 4th gear. 80 and up??

Thanks,

If the car is cold (needle not yet passed the first mark) I'd try to keep my car in 3rd gear and at about 2200-2500 rpm. This is a relatively low rpm, YET load is still low, and it allows a drievable speed. Best of all worlds!

If you need to get on the highway, shift between 2800-3000 rpm.

With a manny tranny the key to longevity is balancing load vs. rpm. Key thing to remember, the car was BUILT for 120 km/h in 5th gear sustained cruizing. So the rpm at that speed should become your mean rpm for every day driving. However, the lower the gear you are in, the lower the load, so you can shift earlier. Like 1st, you can shift at 2500, 2nd by 2800, 3rd by 3000, 4th by 3500-4000... those are more or less optimal shift points for a WARM car for daily driving.

Cold car, try 3rd gear 2200-2500 rpm sustained cruizing.

so shifting at 6K+ isfor every shift is bad? :p

I agree with your assesment there of daily driver for racing though I only shift when the "shift idiot" light blinds me :p

Bruno this is very useful information. Simple.... But I bet a lot of people don't follow these guidelines.

Thanks again,

I have also noticed that my B16A doesn't like the cold weather AT ALL......I have to really crank her to get it going after a cold night.

I guess the B16's have an issue with cold weather........:cry:

ALL engines are harder to start in the cold

LET YOUR FUEL PUMP PRIME, THEN CRANK!

:dito: I wait till I know it's pressurized then turn the key

So just turn the key to accessory leave it there for a few seconds then crank!?!?!?!

Is what you mean by prime???
:shakehand

yes

thats what i do as well!!!

PRIME baby!...

past accessory, but not so that its cranking

put the key in the on position

Dont make a daily habbit of that, or your new best freinds will be the Honda parts guy and the new 200$ hub and bearing assy he holding in his hand :naughty:

werd BoOsTZex!

:haha: :haha: :haha:

Ya man! Thats for sure. Now the Honda parts guy is one person I would rather not see in my whole life!!

A little bit of fun every now and then won't do any hurm. But to make a habbit of it is gonna cost some big coin!
