I was wondering who here has tried out the 110 Octane gas? My gas tank is about to go empty and I am thinking about trying out this gas. There are three things though that I question:
1) Is paying 4$ for 110 (instead of 2.1 for 93) Worth it? Can you feel the difference (any at all)?
2) Is 110 supposed to give you little more horse power only, or does it "treat" your engine better using 110 instead of 93 aswell?
3) My car has 2200 miles as of now, and I have had 1 oilchange done (Manual suggests 3700 or 3 months, so I went after 3 months). Will putting this 110 octane gas damage my engine in any way? will it improove the engine in any way? Nothing will happen (other than the supposed extra hp)?

I am sure there are plenty wise people here who know the answers to these questions, and I thank them for posting in advanced.

 

Speedco (name of gas station) has sunoco 110 racing fuel for 4.1$ i think.

91 octane at 3.1$ WTF? Shell offers 93 at 2.0-2.1 here at Melbourne, FL!

wow 91 at $3.1 is a ripoff!

 

G-Pimp... do you get **** lube with that gas? You are getting butt focked my friend.

 

Im soooo sry guys and no i didnt get an **** lube, hehe. I just filled up the tank and its $2.45. I was on crack at that moment. Sry about the ****-up. I messed up. My bad.

 

HaHaHahaHaHahahahaha gdup35 you`re a funny ****
lol lol lol lol lol lol lol lol lol lol lol lol
that was funnnnnnnny!

 

You will feel the difference but it's not good for your car, usually mix a few gallons with 87 thats the best method. I wouldnt suggest using it more than just for the track, its really not good to run that high of octane in your car.

 

Whatever you do make sure it is UNLEADED gas. Here in CA I haven't seen anything above 100 Unleaded.

Personally haven't noticed much difference between 96 and 100 on auto sedan. 91 - 96 difference is substantial. Mostly smoothness and icreased mpg although I wouldn't be surprised if it made some power if the car was dynoed.

 

Thanks, if it hurts my car, then I dont want it. I rather keep my car in optimum status than ruin it for getting some extra HP. Its not like I race on track anyway. I just thought that it might be better for the engine or at least as good as 93 while giving me a little more HP.

@ G-Pimp - 2.45$ still **** **** money. Ive never seen gas over here (93 unleaded from Shell or Mobile 1) cost over $2.19 it usually costs 2.0X though.

G-Pimp try filling up at another station. Go to http://www.gasbuddy.com/ and you might find more reasonable prices for gas.

 

I feel like I've been giving my baby tap water instead of Fiji Water I just now switched from 83 to 91 and man I can tell the difference.

 

Thanx for the link G35 coupe 6MT. I am getting ripped off. Maybe I will look for another station even though in LA, its not too much less.

 

SCC magazine dynoed a 350Z with 91 octane and then 100 octane and they gained 8-10whp across the board. This only proved what I knew all along about these VQ motors, they have overly sensitive knock sensors. I think running 100 octane in an NA is a bit extreme, but I know that my Maxima always posted its' best trap speeds and ETs with ~95 octane compared to the 91/92. I plan on running some 95/96 octane when I go to the track. Any additional power I can get, the better. I see no point in running anything over 91-93 on the street, but at the track, adding some extra octane may help keep your knock sensor detecting mild or false knock.

As for 110 octane, I wouldn't do it. Chances are it's leaded. FYI, lead is an octane booster and I've never heard of unleaded 110 octane. The highest I know of is unleaded 104 octane.

 

Deffinately dont put a full tank of that in your car, the best thing to do is mix it, it can't hurt to do it occasionally, perhaps it will clean teh engine out or something but for everyday driving nothing more than 93, even when ur at the track you should put but 1-2 gall. of that in there.

 

FYI, higher octane doesn't equal cleaner fuel. Octane is a rating that describes the fuel resistance to burn. The higher the octane, the more resistant it is to burn. Many high performance engines with high compression ratios (10:1-11.5:1) or forced induction require 91+ octane fuels because high compression ratios and/or boost creates a lot of heat. Running lower octane fuel through these motors can be a problem because the excessive heat can preignite the fuel and cause what is commonly refered to as detonation. Running high octane in a motor that doesn't need is a waste of gas and can actually hurt performance because the fuel is so resistant to burning effectively.

 

You see? Thats what I meant when I said I knew people at this forum had wide amount of knowledge lol. Thnx for your help DaveB.

I have one more question reguarding fuel. Ive been told that Shell and BP are the best Gas brands. The shell station I know has 93 unleaded while BP has 91 unleaded. Is one better over the other? Which one should I get? There is a Mobile 1 with 93 closer thant the Shell 93... is Mobile 1 as good as Shell or should I just go to Shell?

p.s. Ive heard that Shell has V-Power and Optiplex types of fuel what are these?

 

Its ok to run higher octane. You just have to check if its leaded or unleaded. Gas that is not unleaded has been shown to damage oxygen sensors which in turn are used by the ECU to monitor your air/fuel and makes adjustments accordingly. If your oxygen sensor goes bad then your car runs crappy cause the ECU cannot get an accurate signal from the O2.

Most of the unleaded gas you will find is between 87-103 octane and most of the leaded are between 104-115 octane.

I use to run C16 which I believe is around a 115octane rateing in my turbo eclipse when I went to the track, but on corner store pump gas I would use 93.

If you put in 100 unleaded octane it will not hurt your car one bit and your ECU will adjust for it over a period of time. Once you go back to whatever else octane you normally use, then the ECU will adjust back to it after a while. Keep in mind that your not going to put 100 octane in and immediately feel a difference unless your tank is bone dry. The ECU needs time to adjust to the higher octane and vice versa.
