B16A1 - Which Fuel? 95/98?

[Jaiiiwon]

ahh really?

in that case, 98 = win. ^_^

but I still woudn't mind testing it out. My mate, he's got the same car as you. He used 100, and it took him everywhere!

Acting like a moderator? Moderators are just people, they rarely act differently on forums I go to.
If that evidence is good enough for you then fine. Its not like the weather is hotter during 6 months of the year compared to the other half :|
Its your money in the end. And if you are dim enough to be swayed by a placebo effect then good on you.

[azn_k3nt]

hey hey then what do u recommend for the k-series (cu2 engines)...ive been using bp ultimate ever since picking it up at the dealer

[Jaiiiwon]

You act like a moderator cause you try imply that you have authority over others. Especially in a sense that its opinions. Thinking that your opinion is above everyone else. Get over it! its opinions! everyone has their own. Why you trying convince everyone that yours is better?!

My evidence is.. Dam well good evidence, what can be better than drivability and fuel efficiency?

And yes its my money, but it still ends up being better. what's a few cents for extra 100kms (approx) on your tank?
from empty to full tank is around $50 for me. that extra few cents a litre has no effect on me mate.. its like what? $2. You're having a massive grump to me, over a bloody $2!!

and FYI.. how is it a placebo, if its facts with evidence?
placebo effect is just something that makes you think it works. But its not only me that thinks it works.. my car also thinks it works. but you know what? the milege counter doesn't lie when measuring distances. It displays what it measures. and it measured that 98 gives out more kms in a tank more than 95. Sure i can say this and that, but my car supports that message.

and you now what? you're opinion doesn't even matter in this question anyway. LOOK AT THE TITLE. he has a B series. Not a piece of scrap H series.
OH n look! its says EM1 on my info.. meaning i have B series as well. So wouldn't that mean, whatever works for me could infact be a better comparison for him than you?

Where's all you're evidence mate? All you been saying is crap that probably came outa your ass. Do us all a favour, go sit in the toilet for an hour or two. because you're full of it!

i've put out my opinion and gave you evidence. You don't like it. well then shut up, its my opinion and i've stated why that's what i believe. And you've done you're bit. Just leave it as that. Stop trying imply your opinion on me, thinking your right, because mate, the only thing that's been a pro of 95 over 98 is the fact that's its cheaper by a few cents. And like i said before it only ends up being an extra $2.

so yeah.. if you want to save yourself $2 sure.. go right ahead.. but i'll enjoy putting my extra $2 on fuel that gives me way more kms then 95 does.

and if you still disagree, well that's your problem not mine. maybe im not such a tight ass like you.


Goodbye Mr. Grump, it was nice conversing with you.

[gumus89]

If you werent so retarded you could see that your "test" has too many variables for you to pin-point where its coming from. You think its the fuel, I say there could be a number of things which can have a much more profound effect on economy.
If you cant understand that fine, but I hope others that may read it can.

Oh and btw, your fuel gauge does lie. The only way to be anywhere near accurate about fuel economy is to measure how much fuel goes into the tank for a certain number of kilometers, not just oh, I got about XXX kms for a whole tank. How much is a whole tank? Did you go down to empty? Did you use 3 litres more before filling than last time, making it look like you got further on the "tank"?

[VT3C]

My god, what is wrong with you people? Give me a good reason to use 98 over 95?

HAHAH good ol' Ozhonda..

OK well your GEN1 B16 came from Japan.. only first gen B16's were available in Japan and some of Europe - I am not sure about the EDM spec.. JAPAN uses 100RON fuel minimum.
all aus-delivered Hondas are 'de-tuned' to cope with our lower RON fuels..

so if you have a stock Aus-delivered honda, u can run it on regular unleadded as reccomended in the service manual. however it will always run smoother and better lubrication for your valvetrain if you use a higher RON fuel.

if your motor is a swapped JDM motor then it's tuned for 100RON so using 98 is still not quite being fully optimised however the difference between being 2 RON short rather than 10 is insignificant. If you were REALLY worried you could retard you ignition timing by a fraction but generalyl if you run 98 you wont have any problems.

using 91 will definately be bad for your JDM motor and you will HEAR the difference in the valvetrain almost instantly.

over the past 15 years I have experimented with all of the fuels from all brands and my testing included NEW hondas with electronic fuel consumption meters etc. and for the extra few cents, you get extended milage from the petrol so in my opinion the extra expense doesnt exist as it works out about the same in the end but i would much prefer to have the added lubrication of my valves and cooler cyllinder temps than $2 in my pocket after filling up a whole tank LOL.

having said this, my old AUS-delivered B16A (gen2) Del Sol had an OEM decal saying to use 'Premium Unleadded Only' however in 1993 when this car was imported we ONLY had a maximum of 95 RON fuel in australia.

I even run my 23 year old Prelude on 100 and she loves me for it..

[trism]

can you explain to me how using 98ron helps the valvetrain, which doesnt even contact the fuel?

the only thing it might do is stop the combustion chamber surface of the valve from becoming pitted due to detonation...

Here is a perfect illustration of your "detuned" comment for some Domestic Market vehicles.



Although i do have a question for you. How does the engine run smoother and achieve better valvetrain lubrication from higher RON fuels?

[Ryuzaki]

i think overall, honda engines do require better octane, d-series, h-series or b-series. Ive found my d-series runs less kms on 91 than on 95 or 98 for that matter. The car seems more sluggish with 91, im not so sure why, but it does feel alot healthier on premium fuels. I do think 98 is over kill on these engines, but as pointed out, there are more benefits than just knock resistance to be gained.

As far as 100 octane goes, unless the engine was built for that, forget it LOL. Only minority ppl use it, mostly Skyline GTR owners as such. But its been proven that 98 octane can be safely tuned on cars, an making close to 600hp, so i dont see why u really need to run 100 octane.

That's what I had thought... If your engine wasn't designed for it then why...

I've read somewhere that the B16A1 was designed to run on a higher octane fuel but I wanted to get some confirmation. Where's that image from/does it have a list for B-series?

Also, BP Ultimate vs Shell V-Power? And what's the deal with E85?

[EK1 Civic]

Shell builds slime in your system and fouls your injectors over time. Its not a true 98 ron, its got added chemicals to make it 98 ron. Where as BP Ultimate doesnt.

[hmetro24]

Today I filled 98 from bp for 1.42$ for 1 litre 91 was 133.9 so it is not a big deal it least u enjoy the car, keep it clean and get a lil bit performance. just think guys that you filled 91 when the price is 1.40$+. just check the best day to refill your tank.

As far as shell goes, i remember when i filled up my brothers S15 with it, ran crap, Bp98 seems to make it better, yet some other cars, its vice versa, so its pretty divided opinion BP vs Shell
