Buying Guide
Choosing the right octane booster depends on your vehicle and your goals. Here are a few things to consider:
- Octane Requirement: Check your vehicle’s manual to see the recommended octane level. If your car requires premium fuel, an octane booster can help if you’re using regular.
- Performance Goals: Are you looking for a significant performance boost, or just trying to prevent knocking? High-performance vehicles will benefit from more potent boosters like Royal Purple or Torco, while everyday cars can use something milder like Gumout or STP.
- Fuel System Cleaning: Some octane boosters also clean fuel injectors and intake valves. If your car is older or has been sitting for a while, this can be a great added benefit.
- Price: Octane boosters range in price, so consider your budget. Cheaper options might be fine for basic use, but higher-end products often offer better performance and additional benefits.
- Mixing Ratios: Pay attention to the mixing ratios. Some boosters are concentrated and require careful mixing, while others are ready to use.
