Octanium Treat Chart

How long does unleaded VP octane booster last in its original packaging?

An unopened can of VP Octanium Unleaded octane booster will last up to five years.


Is the unleaded VP Racing octane booster safe to use in a Two Stroke engine? Specifically a snowmobile engine? It’s a Polaris 850 Patriot. I only have access to 90 and 88 octane unleaded gas and the manufacturer recommends minimum 91 octane.

Both Octanium & Octanium Unleaded are safe for use in both 2-cycle & 4-cycle applications. The exact dosage will depend on whether or not your application has emission control devices (ECDs). If it does have ECDs, you'll want to use Octanium Unleaded. Please refer to the dosage treat chart above.


Will Octanium® Unleaded leave orange deposits on my spark plugs? Will I have to change my plugs sooner?

In a word, maybe. Octanium Unleaded may cause orange deposits on spark plugs as a result of its high concentration of MMT. As a result, we would recommend adding VP Fuel Cleaner with RP21, which is formulated to clean and restore engine components. In addition, you can also blend Octanium Unleaded with gasoline at specific ratios, which will add even more protection for emission control devices (see chart above).


Can I use VP Octanium® Unleaded octane booster with every fill-up?

If you refer to our recommended mixing chart, then you can use it with every fill-up (see chart above). However, the treat rate is different depending on whether your vehicle has emission control devices, which can be sensitive to prolonged use of products with a high concentration of MMT.


Is your unleaded VP fuel octane booster safe for long-term use? Will it harm my exhaust system and spark plugs?

All things considered, there is a safe blending ratio for both emission control devices and non-emission control device applications when using VP Octanium Unleaded octane booster in every tank. Please refer to the chart on this page.
