The Contenders
If you are looking to run a "Race Gas" tune on your daily driver without buying 55-gallon drums of Sunoco 260 GT, you usually end up comparing two products: Torco Accelerator and BOOSTane Professional.
Both are legitimate "Race Concentrates." Unlike the $5 bottles at AutoZone that offer "points" (tenths of an octane), these two use high concentrations of MMT (Manganese) to raise octane by full numbers (e.g., 93 to 100+). But they are not the same.
At a Glance Comparison
| Feature | Torco Accelerator | BOOSTane Professional |
|---|---|---|
| Primary Ingredient | MMT + Toluene/Mineral Spirits | MMT + Proprietary Carrier |
| Max Octane | ~105 (Practical limit) | 116 (Claimed) |
| Packaging | Metal Can (Prone to dents/rust) | Plastic Bottle |
| Stability | Settles if left sitting | Suspends MMT longer |
Torco Accelerator: The "OG"
Torco has been the standard for decades. It is effectively "race gas concentrate." It works undeniably well. If you mix 32oz into 10 gallons of 93 octane, you will see a massive jump in knock resistance.
The Problem: Torco is known for "fallout." The MMT particles are heavy and sensitive to UV light. If you let a can sit on a shelf for 6 months, or let a mixed tank of gas sit in your car for 3 weeks, the MMT can settle to the bottom. This leads to inconsistent octane ratings from the top of the tank to the bottom.
Pros
- Proven track record in drag racing (decades of data).
- Excellent bulk pricing (5-gallon pails are cheap).
- Very effective if used immediately after mixing.
Cons
- Metal cans are notorious for arriving dented or rusty.
- Faster sediment fallout (must shake tank if stored).
- Pouring from the rectangular can is messy.
BOOSTane Professional: The Modern Tech
BOOSTane entered the market specifically to fix the "settling" issue. They developed a proprietary carrier agent that keeps the heavy MMT particles suspended in the solution much longer.
The Result: You get a more consistent burn. It also allows them to pack a higher concentration of MMT into the bottle without it clumping up, which is why they claim octane numbers as high as 116 (though 102-105 is the realistic target for most users).
Pros
- Stability: Stays mixed in the tank much longer.
- Packaging: Durable plastic bottle with easy pour spout.
- App: They have a great phone app for calculating mix ratios.
Cons
- Typically 15-20% more expensive per ounce than Torco.
- Very distinct chemical smell (wear gloves).
The "Orange Plug" Reality
Both products use MMT. There is no escaping the chemistry: Your spark plugs will turn orange.
This is manganese oxide. It is generally harmless to the combustion process, but it can:
- Coat O2 sensors (reducing their lifespan over 20k+ miles).
- Eventually foul plugs if you run "kill mode" concentrations daily.
- Void manufacturer warranties if the dealer inspects your plugs.
Our Advice: Use these products for track days, dyno sessions, or weekend fun. If you daily drive the car, use a "maintenance dose" (4-6oz per tank) rather than a full quart, or stick to pump gas maps.
Verdict: Which Should You Buy?
Winner: BOOSTane Professional
The price difference is negligible compared to the cost of an engine rebuild. The suspension stability of BOOSTane makes it the safer choice for modern fuel-injected engines where a momentary drop in octane can cause super-knock (LSPI). Plus, the plastic bottle is infinitely better for keeping in your trunk without leaking.
