2-Stroke Oil is the type that is mixed with fuel, either by premixing manually before adding it to the fuel tank or, in more modern systems, via a separate tank and pump that mixes the oil with the fuel automatically as you drive. 2 Stroke Oil is burnt along with the fuel and therefore needs regularly replacing. 2-Stroke Oil is not suitable for use as a sump oil that you would typically find in car engine. This would be described as a 4-Stroke oil.

It is designed for both pre-mix or the latest generation motorcycles and scooters with oil injection systems

Some marine applications have a requirement for a particularly 2-Stroke specification that is not carried on Halfords Motorcycle and Scooter Engine Oil 2 Stroke. It would therefore be best to check in the owner's handbook or with the engine manufacturer or marine application specialist whether there are any specific requirements for 2 Stroke for your engine before purchasing the Halfords product.

Hi, thanks for your interest in Halfords products. Halfords Motorcycle and Scooter Engine Oil 2 Stroke 1ltr is made predominantly from components that are derived from the refining of crude oil and in that sense it can be described as 'petroleum' or 'mineral' based. Hope this helps. Thanks.
