It is fully organic and contains no metal compounds (no lead, manganese or phosphorus), and it blends readily with all petrol as well as alcohol and nitro mixtures.\u003c\/p\u003e\u003cp\u003eBy changing the burn rate and lifting the auto-ignition temperature of your air\/fuel mix, Hi-Test holds back detonation and pre-ignition. That stops the “pinging” and “knocking” that can otherwise cause damage, and lets you run higher compression ratios for more horsepower.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDosage:\u003c\/strong\u003e use one to four ounces per gallon of fuel. One ounce per gallon lifts the effective octane number by roughly four points, depending on the octane of the base fuel. Racing engines, very high compression engines or very poor quality fuel may need a stronger mix.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRaises octane level\u003c\/li\u003e\n\u003cli\u003eStops knock and ping\u003c\/li\u003e\n\u003cli\u003eIncreases horsepower\u003c\/li\u003e\n\u003cli\u003eSuitable for 2-stroke (2-cycle) and 4-stroke (4-cycle) engines\u003c\/li\u003e\n\u003cli\u003eCleans the fuel system\u003c\/li\u003e\n\u003cli\u003eCompatible with every fuel, nitro and alcohol mixes included\u003c\/li\u003e\n\u003cli\u003eGives best results when combined with Maxima engine oils\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Maxima","offers":[{"title":"Default Title","offer_id":58911024513288,"sku":"220114","price":14.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1049\/4201\/0632\/files\/maxima-hi-test-octance-booster-473ml.png?v=1790730074"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1049\/4201\/0632\/collections\/220114_1.png?v=1790635138","url":"https:\/\/apexpowersports.co.uk\/collections\/additives.oembed","provider":"Apex Powersports","version":"1.0","type":"link"}
