Do I Have to Put Premium Gas in My Infiniti Q50?
The short answer is: yes, you should use premium gasoline in your Infiniti Q50. Your owner's manual explicitly states this requirement, and ignoring it can lead to significant engine problems and potentially void your warranty. Let's delve deeper into why.
Why Premium Gas for the Infiniti Q50?
The Infiniti Q50's engine is designed for premium fuel (typically 91 octane or higher). This is due to its high compression ratio. High compression engines squeeze the air and fuel mixture more tightly before ignition. Regular gasoline, with its lower octane rating, can ignite prematurely (knocking or pinging), leading to:
- Reduced Engine Performance: Knocking can limit the engine's power and responsiveness. You might notice a lack of acceleration or sluggishness.
- Engine Damage: Sustained knocking can cause damage to internal engine components, potentially requiring costly repairs. This can include damage to pistons, connecting rods, and even the engine block.
- Warranty Issues: Using regular gas when premium is specified will likely void your warranty, leaving you responsible for expensive repairs.
What Happens if I Use Regular Gas in My Q50?
While your car might run on regular gas for a short period, it won't perform optimally and could suffer long-term damage. You'll likely notice a decrease in power, a rougher idle, and potentially even a check engine light illuminating. The most serious consequence, however, is the potential for permanent engine damage.
What Octane Rating Should I Use?
Your owner's manual will specify the minimum recommended octane rating. While you can use a higher octane rating than recommended (e.g., 93 octane instead of 91), there's no significant performance benefit, and it's simply an unnecessary expense. Sticking to the manufacturer's recommendation is the best course of action.
How Can I Tell if I've Accidentally Used Regular Gas?
If you suspect you've put regular gas in your Q50, you might experience some of the symptoms mentioned above. However, a single tank of regular gas isn't likely to cause irreparable damage. Fill the tank with the correct premium fuel as soon as possible to mitigate any potential issues. It's always best to double-check the fuel pump nozzle to ensure you're using the correct type of fuel.
What if Premium Gas is Expensive or Unavailable?
Premium gas does cost more than regular gas, but the potential cost of engine damage far outweighs the difference in fuel prices. Consider the long-term investment in your vehicle and the avoidance of potentially massive repair bills. If premium gas is unavailable, it's better to delay your refueling until you can access the correct fuel.
Can I Mix Regular and Premium Gas?
While mixing a small amount of regular gas with premium might not cause immediate damage, it's not recommended. Always strive to use the specified octane rating consistently.
In conclusion, using premium gasoline in your Infiniti Q50 is not optional; it's crucial for maintaining its performance, longevity, and warranty coverage. Always consult your owner's manual for specific fuel recommendations and prioritize using the correct fuel type to protect your investment.
