Colorado has 85 octane gas because it is one of the highest altitude states in the country. The air is thinner at high altitudes, which means that the fuel needs to be more volatile in order to combust properly. That’s why most cars in Colorado are designed to run on 87 octane gas.
However, some vehicles require premium (91 octane) gas, so be sure to check your owner’s manual before filling up.
Why Does Colorado Have 85 Octane Gas?
Colorado has a higher elevation than most states, which means that the air is thinner. This causes engines to run hotter, and therefore, require a higher octane gas.
Some people might think that this is a disadvantage to living in Colorado, but it’s actually not. The high octane gas helps keep engines running smoothly and efficiently. So, even though it might cost a little bit more, it’s worth it in the long run.
Can I Use 85 Octane Instead of 87
If your car’s owner’s manual says you can use 87 octane gasoline, you can probably also use 85 octane. In most cases, using a lower-octane fuel than what is recommended by the manufacturer won’t have any negative effects on your car. There may even be some benefits to using a lower-octane fuel—it could improve your car’s mileage and emission output slightly.
Of course, if you’re looking for the best performance from your car, you should always use the gas that is recommended by the manufacturer.

Is 85 Gas the Same As 87 in Colorado?
Colorado has two types of gasoline: 87 and 85. E85 is a blend of 85% ethanol and 15% gasoline. It can only be used in flex-fuel vehicles (FFVs), which are specially designed to run on either unleaded gasoline or E85.
Most87 octane gasolines in Colorado are actually E10, a 10% ethanol blend. So, while they may have the same octane rating, they are not exactly the same fuel.
Ethanol is a renewable resource made from corn and other plant materials.
It helps reduce emissions of carbon monoxide and other pollutants when burned as fuel. In addition, it oxygenates the air, which can help improve air quality.
Although E85 costs more per gallon than regular unleaded gasoline, it usually works out to be cheaper overall because FFVs get better mileage on ethanol blends than on regular gas.
Can I Put 85 in My Car in Colorado?
If you’re looking to put gas in your car in Colorado, the answer is yes – you can absolutely put 85 octane gasoline in your car. In fact, this type of gasoline is often recommended for use in cars that require high-octane fuel.
So why is 85 octane fuel often recommended for use in cars?
One of the benefits of using this type of fuel is that it helps to improve engine performance. Additionally, it can also help to extend the life of your engine by preventing knocking and pinging.
If you’re curious about whether or not you should put 85 octane gasoline in your car, be sure to speak with a qualified mechanic who can give you specific advice for your make and model of vehicle.
Does Colorado Use 85 Octane?
Yes, Colorado does use 85 octane gasoline. In fact, most states in the Rocky Mountain region use this type of gasoline. The main reason for this is because the higher altitude makes it difficult to start a car with lower octane levels.
Additionally, the climate is generally colder in these states, so the fuel needs to be able to withstand extreme temperatures.
Why Do Some States Have 85 Octane?
Some states have 85 octane as a minimum fuel standard to protect older vehicles from engine damage that can be caused by using lower-octane gasoline. The higher the octane number, the greater a fuel’s ability to resist “knocking” or “pinging” during combustion, caused by the air/fuel mixture detonating prematurely in the engine.
Detonation knock can cause engine damage because it creates high temperatures in the cylinders that can melt piston rings and damage valves.
When these high temperatures occur, deposits can form on cylinder walls, pistons and valve heads, which can lead to increased wear and tear on these parts.
While most newer vehicles are designed to run on unleaded gasoline with a lower octane rating, some still require premium gasoline with a higher octane rating like 85 octane.
Conclusion
Colorado has 85 octane gas because it is located at a high altitude. The air is thinner at high altitudes, which means that there is less oxygen available for combustion. Therefore, higher octane gasoline is needed to prevent engine knocking.
