## Abstract

Described are preferred compositions for a motor fuel. Such motor fuels may be particularly well suited for use in the motor of an aircraft. In particular, compositions of the present disclosure may comprise alicyclic alkanes, straight or branched chain alkanes, and aromatics. In a preferred embodiment, the fuel comprises cyclopentane, isooctane, and one or more aromatics selected from xylene, toluene, and trimethylbenzenes. The present disclosure describes a full spectrum of unleaded fuels with various motor octane (MON) values to address a wide range of aviation fuel needs in the global marketplace.

## Claims

### Claim 1

A motor fuel comprising:
20-40 wt % cyclopentane, 35-40 wt % isooctane and 20-30 wt % aromatics,
the aromatics being selected from the group consisting of toluene, xylene and trimethylbenzene,
the motor fuel comprising less than 0.1 ml/gallon of tetraethyl lead, less than 0.3 vol % of MTBE, less than 0.3 vol % of ETBE and less than 0.3 vol % of TAME,
the motor fuel further comprising less than 0.5 wt % aromatic amines.

### Claim 2 (depends on 1)

The motor fuel of claim 1 in which said aromatic comprises m-xylene.

### Claim 3 (depends on 2)

The motor fuel of claim 2 in which said aromatic further comprises 1,3,5-trimethylbenzene.

### Claim 4 (depends on 1)

The motor fuel of claim 1, wherein said motor fuel comprises less than about 0.5 percent by weight of added lead compounds or octane enhancing fuel additives.

### Claim 5 (depends on 1)

The motor fuel of claim 1 wherein the motor fuel has a motor octane number greater than 100.

### Claim 6 (depends on 1)

The motor fuel of claim 1 consisting essentially of cyclopentane, isooctane and xylene.

### Claim 7 (depends on 6)

The motor fuel of claim 6 wherein the motor fuel has a motor octane number greater than 100.
