What do you need 110 octane for? More octane than an engine is designed to use has no benefit (except to lighten your wallet).

Sunoco 105 racing fuel is available here for a measly $10.00 a gallon... I think I'll pass! LOL

I use Sunoco non-ethanol 90 in all my carbureted engines (including lawn equipment, pressure washer, etc.). $3.25 per gallon in Panama City.

I did a little research Joe and it seems the highest "pump gas octane" offered in the USA was 102. This was back in the 1960s muscle car era.... Octane pretty much limits the compression ratio you can run as I understand it. I think the limit is about 10:1 at the current octane ratings offered. My H-D is this ratio and I can just barely obtain a very slight ping if I dog the engine high gear, low RPM running the 90 ethanol free. The bike uses a Mikuni.

Different octane rating system. RON vs. MON, etc.

In reply to a post by Steve S Different octane rating system. RON vs. MON, etc.

x2 thumbs up Because of the different octane rating system in use at time of manufacture, a current 110 octane rating would be overkill in our MGBs. In my area, I found no difference between ethanol free 92 and ethanol 92. The only thing that the ethanol free offered was a 17 mile drive to get it and it lightened my wallet a bit.

The spokesman from the Casino Tribe said 110, on the news ???? That is Indian land, regular rules are a little different I think. Besides that, it is real close to the lakes up there, and I think those HP Jet boats run race gas. ????? Yeh ???

The big thing is finding ethanol-free gas in California. Very hard to find. I am considering draining my fuel tank and running a little of the 94 octane lawnmower fuel that comes in tin cans (price, don't even ask) if my car is going to sit any length of time.

The cars run fine on ethanol, but dang, if they sit very long with the same fuel in the tank, things get ugly fast.

100+ octane fuel is available at some stations, but is not the same thing as what the owner's manual calls for. The octane ratings in the manual are RON, which are several numbers higher than the octane rating of the same fuel here in the USA.

If you use this very high octane petrol, take care. One way to achieve this is to include a lot of benzene in the mix. This is a serious carcinogen - nasty. The alternative is to add a lot of tetraethyl lead. Also nasty and probably not legal due to the pollution caused by the lead.

100 octane is - I think - used by light aircraft as the standard fuel.

I'll toss in my two cents worth here on ethanol in gas. It is a know fact that ethanol in gas accelerates greatly the deterioration of rubber hoses, fuel pump diaphrams. etc. That is why if you look, you can now buy fuel hoses that is specifically designed for use in ethanol added fuels. It's more expensive, but in my opinion, if you use fuel with ethanol in it, it is well worth the investment.
About the above comment on tetraethyl lead in gas, it was used in gas for one purpose only. And that is for lubrication of the valves and valve seats. It did increase the octane rating, but at a very minimal amount. That is why now if you rebuild the drivetrain, it is recommended to use hardened valves and valve seats. (stallite)
If you use NOS unhardened seats and valves, they will wear a lot quicker because of the absence of the tetraethyl lead.
