Q: dual sport 3.50 liters does this work for it and how do i mix that

13 years ago
2 Answers
  • A: The best way to mix it is to add it straight to your gas tank when you're filling up at the gas station. Add some octane booster in your tank first, followed by premium gasoline to achieve the best results.

Q: can I use this in my 2 stroke dirt bike?

13 years ago
2 Answers
  • A: You could, yes but usually most 2 cycle engines have a lower compression. This definitely won't hurt it but probably won't do anything. Waste of money I'd say. Simply use better quality 2 cycle racing oil and fresh gas for best results

Q: max octane level Hi there. Will this product upgrade octane level 87 to octane level 91 in a 68 litre tank with one bottle? Basically 4 point upgrade.

  • A: When OB is added to 87 octane fuel you get approximately a 1 octane number increase, depending on the particular fuel. When added to 91 octane fuel the increase is somewhat less.
