110 octane gas in a stock DSM SAFE?!

[DSMnOOb00]

i found a place that sells 110 octane gas in my area, but is it safe for me to run that in my stock 97 gsx? what upgrades will i need to make it 100% safe?

If you have no knock and are 100% stock, the only harm 110 octane will do is empty your wallet. The only good it will do for you is...nothing.

Octane just decreases the chance of knock, so if you're not knocking on 91 octane, that'll do the same thing at less cost.

There is no benefit on using 110otc fuel if your car in 100% stock, you won´t gain HPS you will be running safer,there ins´t any danger at all

get a logger, a mbc and turn up the boost till you knock. I bet you get some good boost out of the stock fuel system with that octane in there.

It might foul up your o2 sensor because 110 is leaded if you run it straight or dont dilute it enough with pump gas, if you do you happen to run it, put some lube in it (marvel mystery oil, atf, fuel lube etc...)

IIRC you can get 110 or something in similiar range unleaded. leaded i think is cheaper though.

but yeah kiss any emissions equipment that sees exhaust gases goodbye. EGR will hate it too.

DO NOT use 110 octane if you have a Catalyic converter. it WILL mess up your motor. i had a friend use some in his Celica (mildly modded) and he motor just crapped on him...spent about 1500 to buy a whole new engine and start all over again with mods. When he asked how come it didnt with my car, i said "one i have a DSM and it knows not to crap on me, and two because i have no cats"

from what i know from 110 octane (without a logger and just "feeling" my car), my idle was a hell of a lot smoother, i gained more low end torque, could boost more and built boost faster, and my car was quieter...other than that, that's it...

Running 110 leaded in a stock car will result in issues only due to the fact that the catalytic convertor is still on the car (if it is). It will slowly take wear on the O2 sensors also.

It is more in your interest to have a good fresh set of NGK BPR6ES spark plugs gapped at 0.028" in your car.

You are better off running unleaded gas, and your car will like you alot more. Run at least 93 octane if possible.

Look to see if you are near any VP, Sunoco, Turbo Blue or Rockett dealers for more information. VP makes 100, 101, 103 and up to MS 109 unleaded, Sunoco makes 96, 98, 100, and 104 unleaded. Turbo Blue makes a 100 and a 104 unleaded, and Rockett makes a 100 unleaded (in ethanol base or MBTE base). These fuels are in your interests if you plan on modifying your car, and keeping emission equipment on the vehicle. Please if you do use these fuels, have your car tuned properly by a professional.

Only run it if you don't have a cat...as stated above. I've been running it for almost 3 yrs with no o2 sensor failure. It is safe depending on your mods and tune. The general rule of thumb is if you're running over 25psi, you'll need to upgrade the HG and studs. Of course, you'll need to master tuning. Oh yea, let there be lead-coated tailpipes.

That's not completely correct.
Leaded fuel is what hurts catalyic converters, not any specific octane rating.


DSMnOOb00 - You aren't going to benefit from a higher octane unless you specifically tune for it. So, dont waste your money. Also, if this 100 octane that you're looking at is leaded, you will cause premature failure your your O2 sensors and your catalyic converter.

ah, i was in a rush when i wrote that...i meant 110 Octane LEADED fuel....

cool, thanks guys for all the help! i guess tuning is the way to go after some upgrades!

Save your money on buying 110 oct and put it into some upgrades. I think your confusing 110 oct with nos
