This is a current Homelite product although not your saw. This clearly recommends 50:1 as do I. I find no OM for your saw, a “PS33 Chain Saw UT-10788” http://www.homelite.com/product_manual/file_url/66/UT10540_60_80_QSG.pdf Dolmar, Echo, Efco, Homelite, Husqvarna, Jonsered, Makita, Oleo-Mac, Red Max, Ryobi, Shindaiwa, Solo, Spear & Jackson, Stihl & Tanaka; all recommend 50:1 and have for a number of years. • 1 gallon of premium fuel to 2.6 ounces of quality 2-cycle oil. • 4 liters of premium fuel to 80 milliliters of quality 2-cycle oil. I suggest you contact Homelite and request an OM for your saw. Homelite/Ryobi.com (Contact Us) https://register.homelite.com/contact_us/new Please ask they prove a link to a site where ALL homelite product OMs may be accessed.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Mix 2.6 ounces of two-cycle engine oil with 1 gallon of unleaded gasoline in a container approved for gas, instructs Reference. Do not use two-cycle outboard oil or gasoline that contains more than 10 percent ethanol. Mix the fuel and oil thoroughly before you fuel the chain saw with the mixture.
Mid-grade unleaded gasoline with a minimum octane rating of 89 is recommended for your mixture. Fuel with a lower octane rating may increase engine temperatures, increasing the risk of piston seizure and damage to the engine.
Yes. All gas-powered chainsaws need gas mixed with oil in order to work correctly. The mixed gas ensures the smooth operation of the engine by providing lubrication and reducing its temperature to manageable levels. This is achieved by mixing oil and gas in specific ratios.
Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.
STIHL recommends that customers use a minimum of 89 octane fuel. If a customer chooses to use a 91 or 93 octane fuel, no damage to the engine will result. However, using an 87 octane fuel could lead to serious engine damage.
We recommend in all of our owners` manuals that you should only use high-quality brand-name petrol with a minimum octane rating of 90, but we can reassure you that petrol with an ethanol content of 10% or less, like the new E10 petrol will not cause a problem with your STIHL petrol tool.
Two-stroke (or 2-cycle) engines require a mixture of fuel and oil be added to the fuel tank. This mixture results in both engine combustion and lubrication. Operating a 2-Stroke engine on gasoline alone will result in engine failure.
The recommended 50-to-1 fuel mixture includes 2.6 ounces of a high-quality, two-cycle oil with added fuel stabilizers and 1 gallon of unleaded 87-octane gas. Homelite recommends using their brand of oils, specifically designed to work in any model with a 50-to-1 fuel ratio.
For a mixing ratio of 1 : 50 you need 5 litres of petrol and 0.10 litres (100cm³) of STIHL two-stroke oil.
Modern gasoline chainsaws run at 50:1 mixture, 50 parts gasoline to 1 part oil. Older chainsaws can require 16:1 mixtures or 32:1 (most common). Two-stroke engines are much more efficient now, as well as having cleaner combustion. At most automotive stores, pre-mix fuel can be bought in 50:1 and 40:1 mixtures.
50 to1 means 50 parts of gas to 1 part of oil. So the 40 to 1 mixture is more oily and provides better lubrication for your piston rings. The downside is it will foul out your spark plug sooner, but that`s no big deal because it`s simple to pull the plug out and clean it and stick it back in.
The 2-stroke 37cc engine is tough enough to handle all branches, firewood, and other common sawing applications.
Husqvarna two-stroke engines are designed to run on clean, fresh, unleaded petrol.
The recommended 50-to-1 fuel mixture includes 2.6 ounces of a high-quality, two-cycle oil with added fuel stabilizers and 1 gallon of unleaded 87-octane gas. Homelite recommends using their brand of oils, specifically designed to work in any model with a 50-to-1 fuel ratio.

When my chainsaw is on its side it leaks gas what needs to be replaced
