For example, there are octane percentages of 87 and 88 which differ from each other, as with 89 and 91. So, it is no surprise if you are wondering whether using unleaded 88 will damage your car if it uses 87.
The main and only difference between unleaded 88 and 87 is the octane percentage. Due to the high ethanol, unleaded 88 burns cleaner than regular gas, improves air quality, offers an engine boost, and reduces greenhouse emissions. Many car owners tend to stick to one fuel throughout the life of their vehicle, and rightly so.
Hence, they are not very open-minded about using 88 for their 87 cars. According to experts, it is not advised to use lower-grade gasoline if you are used to the higher-grade types. Still, not many are aware of the unleaded 88 gasoline.

What Is Unleaded 88 Gas Used For?
Unleaded 88 gas is also referred to as E15 and is made of 85% gasoline and 15% octane. This gas offers many advantages compared to the regular 87. The US Environmental Protection Agency EPA declared every vehicle that was manufactured in 2001 and subsequent years and other flex-fuel compatible cars safe to use unleaded 88.
Before approving the cars and recommending the E15 gasoline for use, the EPA tested and certified them for its use. However, it is important to note that some of the higher-end cars advise sticking to premium gas and mid-grade fuels.

However, if you use it in car models that were manufactured before 2001, offroad equipment, or vehicles with heavy-duty engines, it could result in some issues such as fluid leaks or overheating.
What Vehicles Can Use Unleaded 88?
You cannot blindly use unleaded 88 until you confirm your car is certified. The EPA has certified all the vehicles that were manufactured from 2001 as safe to use unleaded 88 gas. This includes all trucks, SUVs, as well as flex-fuel-compatible vehicles.
However, you are still advised to refer to the owner’s manual to confirm if your car model is recommended for use with an unleaded 88. Most high-end cars do not recommend using gas.
All other vehicles that were manufactured before 2001 have not been approved for use of gas or those with heavy-duty engines such as delivery trucks.

Therefore, due to the higher octane content, 88 burns cleaner hence reducing greenhouse emissions. It also boasts boosting engine power and offers improved air quality.
Moreover, unleaded 88 is cheaper than its counterpart 87. This is because it has a higher ethanol rating, and there are ethanol subsidies offered by the government. Hence, the higher the octane content, the lower the price.
