RJB Energy supplies four products to New Jersey gas station owners and operators: regular, plus and super (premium) gasoline, and diesel. This page explains what those grades are in plain terms, so that you can describe what your station needs when you ask for supply information.
Four products, one scale
Where each grade sits on the octane scale
The octane number on a pump label is the average of two lab tests, written (R+M)/2. The bars below show the general ranges published by the US Energy Information Administration. They are not a specification of any RJB Energy product.
- Regulargenerally 87
- Plus (midgrade)generally 89 to 90
- Super / premiumgenerally 91 to 94
- Dieselno octane rating; ultra-low-sulfur, 15 ppm sulfur max

What the grades mean
Gasoline grades are separated by octane rating, which is a measure of how well a fuel resists knocking (early, uncontrolled ignition) in an engine. The number posted on a pump in the United States is the average of two lab methods, the research and motor octane numbers, usually written (R+M)/2. According to the US Energy Information Administration, regular is generally 87, midgrade 89 to 90 and premium 91 to 94.
A higher grade is not a stronger or cleaner fuel for every vehicle. Engines are designed for a minimum octane rating, and many run correctly on regular. Which grades a station stocks is a retail decision based on its customers and its tanks.
| Product | Typical posted rating | Also called |
|---|---|---|
| Regular | 87 | Unleaded, 87 |
| Plus | 89 to 90 | Midgrade, mid-grade |
| Super / premium | 91 to 94 | Premium, high-octane |
| Diesel | Not rated by octane | Ultra-low-sulfur diesel (ULSD) |
These are general public figures for fuel sold in the United States. They are not a specification of any RJB Energy product. The exact product, blend and any additive package are not stated on this site.
About diesel
Diesel does not use an octane rating. On-road diesel sold in the United States is ultra-low-sulfur diesel, which the US Environmental Protection Agency limits to 15 parts per million of sulfur. Diesel quality is described by other measures, such as cetane number and cold-weather behavior, and suppliers often adjust diesel for winter. If you sell diesel to trucks or fleets, say so in your request.
