Default 110 octane?

Can a stock ls1 run on 110 octane and would there be any advantage?

remember octane is just resistance to detonation. If you car doesnt knock on 87 octane, 93 wont do any good. If you car knocks like crazy on 93, 110 may help. You can tune your car to get more power by using 110 but it involves timing advance etc. So short answer 110 is a waste if 93 is running fine.

But if your LS1 is knocking at 91 octane plus it's not working well. It has a knock sensor that adjusts for 87 octane but 91 should work fine other than hot and high.

Make sure the 110 you're looking at is NOT LEADED if you want to waste your money.

Many people say the see an improvement when they go to a higher octane. Now am sorry but thats a feel good thing to do.

Unless you have mods and they are tuned for that octane (ie Turbo, SC, Nitrous) the engine and the tune will not see a difference. The recommended gasoline for most cars is regular octane. In fact, in most cases, using a higher octane gasoline than your owner’s manual recommends offers absolutely no benefit. It won’t make your car perform better, go faster, get better mileage or run cleaner. Your best bet: listen to your owner’s manual.

What Are Octane Ratings?

Octane ratings measure a gasoline’s ability to resist engine knock, a rattling or pinging sound that results from premature ignition of the compressed fuel-air mixture in one or more cylinders. Most gas stations offer three octane grades: regular, usually 87 octane, mid-grade, usually 89 octane and premium, usually 92 or 93. The ratings must be posted on bright yellow stickers on each gasoline pump.

So unless you like throwing away money then by all means buy the 110 gas and have at it.

Hell the only time i use 110 octane is when I use the bottle because that is what the shot was tuned for. Anything lower than that an I can run into trouble.

Be smart use your brain and put 93/91 in the tank and be on your way.

I'm not aware of 110, I'm aware of 100LL or avgas. That's low lead not unlead. Course I live a sheltered life LOL.

As mentioned if it is knocking at 91 you've got some other problems perhaps.

A Shell station 2 miles from my house sells 110 leaded.....as has been mentioned it is a waste of $$ if your car is not tuned for it...actually may hurt performance.....and the real problem is what the lead does to your O2 sensors and cats.....friend of mine put 110 in his C4 and within 5 miles it started missing and running rough....had to replace the O2 sensors....

I agree with the above posters - no real need to put that kind of octane in C5 engine (unless it has been modified and really needs it).

Just out of curiosity, how much does a gallon of 110 cost?
