The Truth About 93 Octane
Why "Premium" gas might still be causing your ECU to pull timing.
Do You Actually Need a Booster?
Not everyone needs race gas. Here is our simple guide to when additives make financial and mechanical sense.
| Stock Engine (Daily) | Usually No. Unless you have bad gas in your area, factory ECUs are fine on 91/93. |
|---|---|
| "Stage 1/2" Tune | Recommended in Summer. Hot days cause heat soak, and a booster restores lost timing. |
| Big Turbo / Dyno | Required. You need the safety margin to prevent catastrophic knock at high boost. |
Our Testing Criteria
- Knock Resistance: We look for products that actually reduce ignition corrections in datalogs.
- Mixing Reality: Can you actually dose it accurately at the pump?
- Cost Per Point: We calculate the real cost to hit 98 or 100 octane.
