To protect your engine from damage caused by ethanol blends, first check your vehicle’s compatibility with the specific ethanol blend (e.g., E10, E20) by consulting your owner’s manual or fuel cap. If your vehicle is not compatible, avoid using blends with higher ethanol content or use them sparingly. In compatible vehicles, perform regular fuel system maintenance to prevent corrosion and sediment buildup. If you must store your vehicle for an extended period, drain the fuel tank to prevent water absorption and separation.

Steps to follow:

1. Check fuel compatibility:

Consult your owner’s manual or fuel cap to find the maximum ethanol blend your vehicle can handle.

If you are unsure, contact your dealer to confirm compatibility.

2. Use the correct fuel:

If your vehicle is compatible with E10 or E15 fuel, you can use these blends without modifications.

If your vehicle is not compatible with E20, avoid using blends with higher ethanol content.

3. Regular Fuel System Maintenance:

Maintain the fuel system by checking the lines and filters.

Identify and resolve issues such as rough idling, which may indicate a problem.

4. Address Extended Storage:

If you plan to park your vehicle for an extended period, drain the fuel tank to prevent water separation and possible damage.

5. Consider Additives (with Caution):

For vehicles that need a boost or to offset effects such as decreased efficiency, you can use additives that improve combustion or stabilize the fuel.
