Hey guys!
Just curious to see if everyone out here uses 93 Octane gas for their TLs. I have an '03 TL-S w/44K miles. I have used 93 octane from the very beginning. But if it is ok to use 87 or 89, I would rather do that since it so much more cheaper.
Thanks!

 

its ur choice, but I heard it can be harm the engine in long term.

 

well buddy.. if you chose to go down about 10k later your engine might start to ping and then you might be facing a more serious problem down the road..

 

The manual says it is ok, but performance will be affected. Also I have heard a bunch of guys regretting using the lower octane gas because it has killed some part of their engine. My advice, just playing it safe and use the recommended octane rating and you will probably save yourself some headache in future.

 

yeah dood you can totally end up spending wayy more in the end.. the reasons why you have to use high octane is due to the compression. you dont want to mess with it. i fill with 93 and i still supplement with an octane booster ever other fill.

 

ive been using 91 octance since i bought the car and i wouldnt go use anything lower as i have heard that it can cuase several problems in the long run!

every so often i fill up with 94 octane from sunoco... not sure if it actually does anything for my car but it cant hurt anything except for my wallet!

 

With a Type S's compression, I'd stick with premium. On the base model, I've run 87 octane on cross country trips with no problems and nearly 33 mpg most of the time

 

in most cases you are looking at 15 cents a gallon extra from using 87 it adds up to about 3.00 more than 87, thats just like buying a pack of cigs. i guess people don't look at it that way i use 93 in every vehicle i have except my gsxr i use 94 all the time with octane booster keeps the injectors clean.

 

you have a $30k+ car with a pretty powerful engine, give it what it needs. I figure it this way, if I wanted to save on gas, I would have gotten an Accord.

 

Sure, you can use either octane. However, when you use 87 you'll notice a reduction in power. The computer in your car resets your engine for the lower octane.

 

91 and above is required for a reason, man. I don't know why people buy these cars and get cheap over a few cents per gallon at the pump.

The computer will retard the timing to compensate for the lower octane, should you choose to save a couple of bucks at the pump each time. But mechanical parts can only take stress for so long. By using lower octane than required, you're making your car work overtime to compensate for it, not to mention sacrificing performance and efficiency.

If you wanted to save money on gas, you should've checked the EPA rating on the window sticker before you bought the TL, and should have opted for the Accord.

 

i like it cus it gives me peace of mind knowing that it keeping me lubricated

 

I've used Sunoco 94 Octane...the only diff was that it ate the gas faster...i went back to 91....I've used 89 octane..used less gas nad same performance...but was not good for engine..just using 91 for now on.

 

For a couple of cents extra give yourself peace of mind and use the recommended octane rating (91). Higher octane than 91 will give you unnoticeable performance increases. Unless you race on the track, 91 octane is really all you need. In the long run, the money you think you saved by getting the cheap gas is really not worth the aggravation, and will probably cause you grief (besides the decreased performance).

A friend of mine with an I35t thought of the "money" he will apparently save by using lower octane gas began experiencing pinging (rattling noise) while accelerating/ under load. After a tankful of the crappy gas, he switched back to the higher octane, but could not get rid of the pinging. It took him 3-4 tankfuls before the car actually went back to normal. Money saved? Don't think so.

Also, lower octane WILL increase your gas mileage, so if you're thinking saving money, think again.

 

Sorta, it doesn't "reset your engine" it will pull ignition timing to prevent detonation. High compression + high RPMs + low octane gas = knock aka detonation. Retarding the engine timing will decrease performance but it is done as a safety precaution. The ECU will pull enough timing so that it will not harm the engine. Maybe if you ALWAYS used 87 octane tens of thousands of miles down the road you might run into internal engine problems but it is not "bad" for the engine if it is used every now and then.

 

Pinging indicates a lean condition. Lower octane gas could definitely cause this in an engine with a high compression ratio that is designed for 91 octane. On the East coast we get 93 octane and on engines with high compression, advanced timing via ECU or ignition control, or even more so with forced induction there will be an increase in performance.

 

I've had my car for over 2 years.. and I've never used anything less than 93 Premium.. but here's the thing guys.. one time .. about 6 months ago.. I went to a full service station.. and I told the guy Premium gas.. and he accidentally put in regular.. the result: MAJOR pinging !!! so I had to go through 2 bottles of fuel injector cleaner, and then it stopped. So.. it goes to show you, DON'T use regular gas.. Stick with 93 octane. To save $3.00 for an entire tank of gas.. is it really worth it??? Probably not.

 

Don't you hate getting gas in Jersey :o

 

The recommended octane rating of 91 is what is supposed to be used, using anything other than that is a waste of money and/or could harm your engine. Some places don't have 91 octane, but 93, that is what I am running in my car because you don't get 91 here in Texas (or atleast I have not been able to find it).

Using a lower octane will screw your engine up.... I am not going to risk that to save a few cents at the pump... at year end, you may save a couple hundred, but is it worth it when it might cost you a few grand to fix your engine or get a new one???

 

Let's check what is the advantage of 87 vs. 93. Gas price - $.20/gal, power loss - definite. Say you run 20,000 miles/year at 20 miles/gal. That makes "whopping" $200/year difference. I would not risk either my car engine longevity or performance over $200/year.

 

91 octane is recommended in the manual , to use greater octane rating is a waste of money
gas costs enough as it is

 

Not everyone can get 91 octane. Infact most people's premium is 93 octane and the mid-grade is 89 octane. The reason for saying 91 octane in the manual is because in California that's the best you can get.

 

^Game, Set, Match....

 

Just buy the good stuff (91 or HIGHER)....its all about performance. Why have a TypeS and then put crap fuel in it???

PS: in Canada, Ultra94 is about 20cents/litre more than regular 87 octane....its still worth it!!!

 

hey dood in canada..just to let you know ultra is bad for you engine. it has a product called mmt, that messes up your acura. Well atleast the ones in america i am 80% sure its the same in cananda.

 

Case in point: Two identical model Hondas bought almost months apart, mine and my cousin's. I used nothing less than 89 octane as opposed to the recommended 87, my cousin stuck to regular. Three years down the road, my cousin drove my car (probably got used to the pinging on his) and could not believe how the same car with the 89 octane could be so smooth and more powerful compared to his. No additives, no synthetic oil, just higher octane gas. Was the couple of bucks I spent extra gave me peace of mind, most definitely. Now he has forced himself to "rejuvenate" by filling up with Premium 91/93 octane when the prices are low, but then gets used to his pinging when he swithces back to regular. He not me gave the impression that his car had less performance than mine.

As for the US/ Canada gas, I'm pretty sure the gas refined here makes its way to the States and vice versa. I don't think there is a difference since the auto markets are nearly identical. Besides gas, oil and other fluids, except for the speedometer, everything is pretty much the same.

 

not the gas in general just the super premium.. take a look next time you are at the pump, there is a mmt additive.. read your manual it says that mmt is harful to your engine.. however it is kinda fun~!

 

no its not dumbfuck project

stfu if you dont know what your talking about nublet

 

watch your mouth look and read this its out of the manual...
:fingerfawk:

 

Broly, I'm sorry to say, your dumb 16yr old ass got OWN3D!



Open mouth, insert foot.

 

if i lived in canada i would show you a picture of a pump with super premium.. it shows mmt on there.

 

You have a $30K car, don't be a cheap skate ... just spend the extra 4 bucks on the high octane gas. If you could not afford it, you should have gotten a civic DX.

 

Broly just got pWn3d!!


Nice one, Project.
