Your Cobra’s heart is a specifically designed two-stroke engine. To get the most out of it, you should use self-mixing Cobra Mix-Oil, which is thoroughly tested to fulfil the high demands of the oil mix. Its optimal engine lubrication at high temperatures gives low smoke and odor from the exhaust, keeping the engine and spark plug clean.
Cobra Mix-Oil is mixed with fuel in accordance with the model specification, typically in a 2% mix for the latest models. The 1l/34 US fl oz bottle last typically about 40 hours in the Cobra Combi, and up to 60 in Cobra TT and Pro models. The smaller 100ml/3.4 US fl oz bottles make it easy to have a 2% oil mix in 5l/1.32 US gal petrol cans.
