For the love of god use 87! Our cars our actually tuned for 86! We have no knock sensors...higher octane will do nothing.

This has been asked a thousand times, and it's a giant controversy every time.

edit: so people read it dammit

The search button is there for a reason....

the new 02 Si/SiR dosnt even require 91+. You're wasting money if you're buying anything but 87.

our cars were made to run on 87... anything more is kinda a waste of cash

its a proven fact, that unless your engine was designed for it (or if it is so old its detonating everywhere) putting higher octaine gasoline does the 3 following things

1. wastes money

2. makes the same ammount of power as the lower octaine gasolines

and

3. creates more polution.

and who said the new Si doesnt take premium? mine does, and i dont mean just because it uses N20 eiyher, thats in the manual.. then again i dont own a 02 Si...

Actually, I don't use the premiums for same reason you guys think, lol. From what I've read, they use some other chemicals in the premiums that also help keep the engine running better. I will look up the article and link it for you guys.

Your B series has higher compression. I know, I had a 99 Si and it says "Premium Unleaded Fuel Only" on the Gas door.

The 02 Si K20A3 only rev's to 6800rpm...and a compression ratio of 9.8:1. Minimum Octane rating for the motor is 87.

How many miles on your car? Auto or stick? Using 5w20 I assume...

Next oil change try this...use Amsoil synthetic 5w20. Add a bottle of Chevron Techron to a full tank of 87 octane gas. You should notice a big improvement.

BTW, using a higher octane than recommended should result in a loss of power and MPG.

actually i just got an oil change last week and i just filled up the tank right now. i can't stand to get dirty so i take my car to honda to oil changes. i figured if i asked them what was wrong with my car they wouldn't give a bleep... so i'm asking you guys. maybe i'll use some of that Chevron Techron to a full tank of 87 octane gas. it's more expensive, but well worth the try! thanx PESTLNC!

i use 87, only about $2 in my gas tank and can make it last a whole week on daily driving.

Thats pretty good... i use 87, and occasionally 91 when gas is really cheap... but i get around an average of 400 kms/tank.... it's an auto, and mainly local driving... is that good or bad?

gas additives are also a crock. techron, prothane and the rest of the made up crap are just buzz words.

JoeB16, Techron actually works.

If you're getting your oil changed by a dealer, make sure they're not putting in 10w30. I've heard stories of dealers putting that in every car they do changes on. It would definately affect your fuel economy.

 
Rep Power: 0

BTW, expect your MPG to be down while Techron is in your tank. Afterwards it will improve to above what it was before.

ditto.

I usually run around 450km before the needle dips below the 1/4 mark...

I'm yet to crack 5000 on the ride...

It's true, our cars need nothing more than 87. but when i did a test, putiing in full tanks of 87, 89, and 91, the higher ones gave me more miles. why??

 
Rep Power: 0

I don't know where you guys got your Civics but I have an '02 Veloz 5spd 5000km and can regularly get about 700km before NEEDING to gas up (gas light comes at about 600k)! [IMG]i/expressions/face-icon-small-cool.gif[/IMG] I drive about 75% hwy but if I'm playing around (revving over 5k), that number gets a bit smaller of course, but sheesh...only 400km??? WTF? Do you fill your tank all the way? How many kms? Oh, btw, I use *REGULAR* 87 octane gas -- premium gas is a WASTE of $$ that could be buying you guys mods ! Now, if you had a forced induction of some sort, then you NEED higher octane gas, otherwise, it's a big waste of $$.

Normally I agree with you but this time I'll dissagree. 10W30, while it will lower your MPG (not enough for you to actually notice), will help the reliability of your motor on the long term. You can use 5W30 also. That's what I use, either will do the trick. A 20 weight engine oil is too thin for my driving. I recommend it.

Third post, read it.

I'll find the cheapest 87 octane I can get as long as from a known name gas station. Some of those little cheap gas stations have very bad gas.
