10 best stroke oils

Stroke oils, particularly Two-Stroke Engine Oil, are essential components for the proper functioning of two-stroke engines commonly found in outdoor power tools such as chainsaws, lawnmowers, leaf blowers, and other equipment used in the patio and garden. These oils serve several critical functions:

  1. Lubrication: Two-stroke engines require a mixture of oil and gasoline to lubricate the internal components, including the piston, crankshaft, and bearings. This lubrication prevents friction and reduces wear and tear on engine parts.

  2. Combustion: Two-stroke engine oil is designed to burn along with the fuel in the combustion chamber. It helps cool the engine and provides a cushioning effect during the combustion process, improving engine efficiency.

  3. Carbon Deposits: High-quality two-stroke engine oil contains additives that minimize carbon deposits on engine components, helping to maintain engine performance over time.

  4. Emission Control: Modern two-stroke engine oils are formulated to reduce harmful emissions, meeting environmental regulations. They contain low levels of ash and are less polluting than older formulations.

  5. Protection from Rust and Corrosion: These oils also provide protection against rust and corrosion, which is particularly important for outdoor power tools exposed to the elements.

It's crucial to use the correct type and mix ratio of two-stroke engine oil for your specific equipment, as specified in the manufacturer's recommendations.Using the wrong oil or an improper mix ratio can lead to engine damage, reduced performance, and increased emissions.

When purchasing replacement parts and accessories for your outdoor power tools, it's essential to select components that are compatible with your equipment's make and model. This ensures proper fitment and functionality. Regular maintenance and the use of high-quality stroke oils and replacement parts can extend the life of your outdoor power tools and keep them running efficiently.

Answer: The product I ordered and received in August 2015 is a synthetic blend. "Synthetic Blend" is plastered on the front of the jug (but is not in the product that is pictured). I checked the product id# wondering if the wrong product had been shipped. The model # on the jug is 27Q01 and that is what the item description says they are selling.

User questions & answers

Question: Is 6 oz ok for my 80cc bike I have a 1 gal tank and I need 20:1 for after breaking in and 16:1 for breaking in need a response fast I need oil
Answer: you can make the mix what ever you want just read the mix instructions
Question: I have never used this before. Do i need to buy anything else for my trimmer
Answer: I assume you have a 2 cycle trimmer. Read the manual on the correct oil/gas mixture. Most American built trimmers use a 40:1 or 50:1 mixture. 40:1 is 2.6 oz. per gallon. A little less oil if 50:1. Chinese 2 cycle motors still use 25:1 or 20:1 oil mixture. Use 5.1 oz. of oil per gallon of gas for 25:1 or a little more if 20:1 mixture.
Question: How many gallons will this treat if one whole 16 oz bottle is used
Answer: I use 50:1. That takes 2 oz per gallon so I get 8 gallons per bottle. It is great having the squeeze section so you can precisely measure before filling gas can.
Question: What size (oz) is the measure cup on top? Say I neeeded 3.2 oz
Answer: It has numerous markings including 32 to 1 or 3.2 oz there is a graduated scale on the side, loosen the cap and squeeze gently until the desired amount is reached. Should you decide to go with this, I used a sharpie to highlight the markings to make then easier to read

Walmart stores in my area sell this oil for about $10 a quart, so I felt I was getting a decent deal. It would have been a great deal if I would have received 3 jugs as advertised.
