Whereas, the pour point determines the temperature at which an engine oil would freeze and will lose its flowing ability becoming frictionless. They also spend a lot of time going very slowly, with the engine revving quite hard, so a build-up of exhaust fumes and unburnt gunk form the engine is a topic some riders worry about. The pour point of XR77 is comparatively lower which shows that it will freeze later than its contender. Parameter

If you want a clean-burning oil that’s smokeless, or at least low smoke, then try Motul 800 or Mobil 1 MX2T. It has been tested and proven to deliver exceptional acceleration and power at the touch of the throttle.

The trouble is, with a really cheap 2-stroke oil, especially one designed for garden machinery over motorcycles, is that you’ll almost certainly run into problems. When comparing a two-stroke engine to a four-stroke, the most obvious difference is that in a two-stroke engine there are two complete revolutions for every combustion cycle, whereas, in a four-stroke, there are – you guessed it – four! Castrol POWER1 Racing 4T using Race Derived Technology based on Castrol’s long and successful racing association, flows fast and stays strong, reducing internal engine friction even under the most arduous riding conditions. The smell of burnt two-stroke oil is subjective. Some people love it, others can’t get enough of it. Therefore, for each cycle, a 2-stroke engine takes in the petrol it needs to burn and the oil it needs to lubricate the cylinder. This is known as premix or sometimes known as petroil.

On some motorcycles and garden machinery, you will add the two-stroke oil directly into the petrol tank at the correct ratio. This is often referred to as ‘premix’. On other motorcycles and – more commonly – scooters, you’ll have a two-stroke oil tank, where you pour in the neat two-stroke oil and it gets injected into the engine alongside the petrol. This is sometimes referred to as prelube. What does two stroke oil do? It’s really good to know I’m not the only one using Castrol R! And really interesting to hear your replies, so I’ll try to answer as many (or perhaps the few) replies to this topic. Another most important property of a fluid lubricant includes the friction of the lubricant liquid, the load-bearing capacity of the lubricating film, its resistance to the onset of movement relative to the moving parts, and its sealing ability.Legendarisk karting olie - testet gennem utalling sejre på banen. Anbefales til relativt varmtgående motorer - helst over 14.000 omdr. Til kartmotorer med over 20.000 omdr kan Castrol Racing R30 være et fordelagtigt alternativ med sin bedre holdbarhed ved de højeste stempelhastigheder. Til relativt koldtgående motorer - under 55-60 grader - kan Biolube 2t være et bedre alternativ, da den brænder helt rent selv ved lave temperaturer.
