So as never to confuse it with your regular, unleaded fuel used in four-stroke engines. Get yourself a small, separate jerry can to store your two-stroke fuel in.Drain tanks and run your tool out of fuel before putting it away. Don’t leave premixed two-stroke fuel in any tool for an extended period of time.Always start by filling half the amount of the petrol to be used.Not only will it prolong the shelf life of your fuel mix, but it can also help prevent spillage, permeation and evaporation. Use a clean airtight container intended for fuel.Always clean your cap and the surrounding area before filling up to prevent dirt and debris from falling into your tank.If you do need to prolong the life of your two-stroke fuel mix, there are fuel stabilisers that can be added which may extend the shelf life up to twelve months.Avoid storing mixed two-stroke fuel for more than one month.Semi-synthetics cost less than full synthetic oils, offer good combustion properties and give you better lubrication than you’d get from a standard, low quality mineral oil. But mixed with additives and synthetic polymers to deliver a cleaner burn than a strictly petroleum based product. They’re primarily comprised of high-quality mineral oil. Semi-synthetic oil meets you in the middle. Plus additives like octane enhancers, detergents and stabilisers to help burn cleaner than other engine oils. They’re generally formed from a mineral base. With little to none of the mess that a petroleum based oil can leave behind, leaving you with a much cleaner engine. So manufacturers often mix in additives that help improve combustibility.įull synthetic oils demonstrate superior combustion characteristics on top of delivering great lubrication. Over time, you may end up with burnt carbon or gummy residue buildup on the piston which can lead to more maintenance and compromised performance. While oils made from a natural petroleum base do a fair job of cleaning and filtering engine contaminants, they can leave behind heavier deposits than their synthetic counterparts. Mineral oils usually cost less than synthetics and are great for engine lubrication. And also never use oil intended for four stroke engines. Sometimes referred to as Outboard oil (rated TCW). The formulation used in Husqvarna Low Smoke + oil also provides seizure protection, both against lean as well as carbon related piston seizures.Īs a general warning, never use two-stroke oil intended for water-cooled engines in a non water-cooled engine. It also provides a lower engine temperature which extends the engine’s life. This oil gives very low smoke emissions, especially important when used in products often run in densely built up areas. The Low Smoke+ oil is a mix of mineral and synthetic oils. Carefully selected components in this part synthetic oil gives a cleaner engine and less coating on the piston/cylinder walls, exhaust port and crankcase. Husqvarna's HP two-stroke oil is formulated to work well with low-quality fuels. Husqvarna offers two types of two-stroke oil: High Performance, HP oil: (544 0158-09, 1 litre dosage bottle) Now it’s time to make the most important call of them all - choosing the right oil for your two-stroke fuel mix. You’ve got your clean, empty fuel can and a good supply of fresh petrol. While fuel jerry cans are great, newer specialist fuel containers to the market such as the Husqvarna Combi Can have been designed to make storage safer and refueling less messy, thanks to inclusions such as the no spill valves, on-board tool storage and dedicated tank for two-stroke oil. For this reason, it is essential fuel is stored in a clean container specifically designed to carry fuel. The leading cause of contaminated fuel in Australia is dirty fuel storage containers. Starting with a safe fuel storage container A four-stroke engine needs to circulate oil throughout to lubricate these moving parts, where as a two-stroke engine only needs to lubricate the components internal of the combustion chamber, which can be achieved by simply mixing oil in to the fuel it runs on. When it comes to engine lubrication, the difference between a two-stroke and four-stroke engine is that a two-stroke engine has no valve train, timing gears, cams or pushrods, whereas four-stroke engines do. These days, you’ll find two-stroke engines in all kinds of equipment, such as chainsaws, grass trimmers and hedge trimmers, largely because two-stroke engines have fewer moving parts, generate less heat and are in many ways more efficient for their size. The first true two-stroke engines were introduced more than a century ago and used to power motorcycles.
