Valvoline Sytnpower 2T is an advanced 100% synthetic lubricant for 2-stroke engines in 1 liter bottle, with surprising qualities to leave no residue in the combustion chamber or exhaust systems, especially suitable for 4-stroke engines , since these, due to their high temperature in the exhaust system, tend to leave a considerable accumulation of carbon in the valve and in the exhaust manifold. The tests carried out by the best manufacturers of 4T engines in dry carter advise it as Valach, Saito, OS, Moki ect. Of course, it is completely valid for 2T engines, especially those that use canister type exhaust or resonator pipes, since they tend to accumulate more waste. Valid both for premixing and for injection dosing systems. It more than meets the most demanding regulations: JASO FD, ISO EGD, TC API. We recommend a mixing ratio of 50: 1 (never lower 100: 1).
