Use a 40:1
Two-stroke engine – Wikipedia
oil mix ratio. One gallon of gasoline combined with 3.2 oz of two-cycle engine oil. Unsure of the age of your equipment? Use the 40:1 mixture.
How do you make 40 to 1 gas oil mix?
For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas. For a 32:1 mixture, use 4 fluid ounces of oil per gallon of gas.
What is a 40 to 1 fuel mix?
For a 40:1 fuel mixture, use 3.2 fluid oz of oil per gallon of gasoline. For a 50:1 mix of gas to oil, use 2.6 oz of oil per one gallon of gas.
Does 40 to 1 have more oil than 50 to 1?
The 40:1 ratio has more oil compared to gas. That’s why 40:1 oil is slightly denser than 50:1 oil. This higher density helps with the lubrication of the engine. Because of that, the 40:1 ratio has better lubrication of the two.
How much oil do I need for a 40 to 1 ratio?
Use a 40:1 two-cycle oil mix ratio. One gallon of gasoline combined with 3.2 oz of two-cycle engine oil. Unsure of the age of your equipment? Use the 40:1 mixture.
How do you calculate a mix ratio?
Divide 1 by the total number of parts (water + solution). For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9).
What is the best oil to gas ratio for 2-stroke outboards?
For 2-Stroke outboards that require a 50:1 premix of oil/gas we’ve put together the following chart to simplify the calculations. Use ONLY 2-stroke outboard motor oil with an NMMA (National Marine Manufacturer’s Assoc.) certified rating of TCW3. Never use automobile motor oil in your 2-stroke outboard!.
What is the fuel mixture for a Stihl chainsaw?
Using the right type of fuel is critical in the safe and efficient operation of your STIHL equipment. Most STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil. Knowing the proper way to mix your fuel is the first step in keeping it running strong and long.

Can you use regular oil for 2-stroke?
You can’t safely do it. Many years ago, you could use SAE 30 in place of 2 stroke oil, but since about 1960, the additives in normal engine oil will cause ash deposits in the combustion chamber of a 2 stroke engine. These deposits will build up and cause severe ignition problems and eventual engine failure.
Is it better to run lean or rich?
TLDR – running just a little lean could improve fuel economy and give extra power. However, run too lean and you risk engine failure because the engine runs too hot. Whereas running rich can waste fuel and increase pollution but will not damage the engine.
Can I run 40/1 in my Stihl chainsaw?
Can I Run 40/1 In My Stihl Chainsaw? It is fine to use the same modern oil at 40:1 as well. Oil concentrations in your saw will help protect your engine if you use it for heavy duty work such as milling.
Can I use any 2 stroke oil in my chainsaw?
Generic brand oils may not be designed to operate at the temperatures and rpm of modern two stroke chainsaws. To ensure a long trouble free life out of your modern two cycle engine, we strongly recommend using only high quality two stroke oil designed for air cooled high performance engines.
What is special about 2 stroke oil?
A 2-stroke oil will lubricate the engine components by association with the fuel (either by mixing with it or by spraying during combustion), so this oil contains components that promote its combustion.
How much oil do I mix with 5 Litres of gas?
Metric (Litres:Millilitres) Fuel (L) Oil (mL) 3 60 4 80 5 100 7.5 150.
How much oil do I add to 5 Litres of petrol?

What is a 30 to 1 mix ratio?
United States/Metric Ratio Fluid Ounces Per Gallon Milliliter Per Liter 30:1 4.3 33.3 32:1 4 31.3 35:1 3.7 28.6.
How do you calculate water mixing ratio?
Water vapor mixing ratio is unitless, but often we put it in g kg–1. The water vapor mixing ratio, w, is typically at most about 40 g kg–1 or 0.04 kg kg–1, so even for this much water vapor, q = 0.040/(1 + 0.040) = 0.038 or 38 g kg–1.
How do you calculate a 2 1 ratio?
For example if the numbers of boys and girls at a hockey match are in the ratio 2:1 , we know the following information: There are more boys than girls. There are 2 boys for every girl. The number of boys is double the number of girls, which is the same as saying there are half as many girls as boys.
