Fuel recommendation
Use of lower octane gasoline can cause occasional metallic knocking noise in the 
engine and will result in decreased engine performance.
Use of gasoline with a pump octane less than 87 can lead to engine damage.
Your vehicle is designed to operate on premium unleaded gasoline with a pump 
octane of 91 or higher.
If this octane grade is unavailable, regular unleaded gasoline with a pump octane of 
87 or higher may be used temporally.
The use of regular unleaded gasoline can cause metallic knocking noises in the 
engine and will result in decreased engine performance. The long-term use of 
regular-grade gasoline can lead to engine damage.

Top tier detergent gasoline
Because the level of detergency and additives in gasoline vary in the market, Acura 
endorses the use of “TOP TIER Detergent Gasoline” where available to help 
maintain the performance and reliability of your vehicle. TOP TIER Detergent 
Gasoline meets a new gasoline standard jointly established by leading automotive 
manufacturers to meet the needs of today’s advanced engines.
Qualifying gasoline retailers will, in most cases, identify their gasoline as having met 
“TOP TIER Detergent Gasoline” standards at the retail location. This fuel is 
guaranteed to contain the proper level of detergent additives and be free of metallic 
additives. The proper level of detergent additives, and absence of harmful metallic 
additives in gasoline, help avoid build-up of deposits in your engine and emission 
control system.
Unleaded premium gasoline, pump octane number 91 or higher

NOTICE
We recommend quality gasoline containing 
detergent additives that help prevent fuel system and 
engine deposits. In addition, in order to maintain 
good performance, fuel economy, and emissions 
control, we strongly recommend, the use of gasoline 
that does NOT contain harmful manganese-based 
fuel additives such as MMT, if such gasoline is 
available.
Use of gasoline with these additives may adversely 
affect performance, and cause the malfunction 
indicator lamp on your instrument panel to come on. 
If this happens, contact a dealer for service.
