The fuel ratio is 40:1. You can get the TRUfuel that comes in a bottle and stays fresh for a very long period of time. You should be able to get the TRUfuel at Oreilly's Auto parts stores or from Wal-Mart.

SOURCE: what oil gas ratio do

Hello rvan. the ratio is 50:1. the easiest way to achieve this is to buy a 2 gallon plastic gas can and a few of the 2 cycle engine oil bottles that are made especially to add to either one or two gallons of gas. Joe

Don't know that exact trimmer, but I always run 40:1 in all my trimmers, chainsaws, etc. That is 3.2 oz. of 2 cycle oil to one gallon of gasoline. I rebuild these machines daily and run that mix in everyting, except when it's actually specified on the machine.

Ratio of oil to gas?

Hi John:
Two stroke (also called 2-cycle) Mix at 50:1
Some of the Craftsman units were 4 stroke, supposedly environmentally responsible. They took straight gas and had oil in the crank case. Came with a dip-stick to check it.
Personally, I had one and it was the WORST piece of equipment I ever bought from Sears.
I'm back to a 2 stroke STIHL and it is GREAT!

My Craftsman 5.5 hp 14" rear tine tiller starts but doesn't run for long. It blows black smoke and quits. The gas is new and the oil is good.

Black smoke looks like it's burning too much oil. If it is a 2 stroke engine try a lower ratio of 2 stroke oil to gasoline mixture. Make sure you are using 2 stroke oil!
If it's a 4 stroke engine find out why and or how the oil is getting burned.

I have a sears 2 cycle mini tiller that worked great for the first hour but now won't start.

Do not use pre-mix fuel. Clean carburetor. Check age of gas. Cannot be more than 30 days old.
Make sure to use fresh gas w/synthetic 2-cycle oil @ 40:1 ratio (1 gal.) Gas to 3.2 oz. Oil) .Do not use old or stale oil/gas mixture. Always use the proper oil/gas mix. If you do not, your engine will suffer rapid, permanent damage.

Need to know the gas to oil ratio for my feather lite weedeater. Model FL21

"Echo Power Blend Universal 2-Stroke Oil can be used in all of our 2-cycle air-cooled equipment ever made. You may also use this oil in any other brand of 2-cycle air cooled equipment, but it should always be mixed at the 50:1 ratio whether or not it was a 32:1 or 16:1 etc. machine. This oil is the highest quality 2-cycle oil on the market today. There is no need to have more than 1 tank of fuel for your 2-cycle equipment any more."
The above excerpt is from the Echo FAQs (6) here:

Oil Mix Ratio:
The following ratios have been recommended for the last 10-15 years.
Dolmar, Echo, Efco, Homelite, Husqvarna, Jonsered, Makita, Oleo-Mac, Red Max, Ryobi, Shindaiwa, Solo, Spear & Jackson, Stihl & Tanaka; all recommend 50:1.
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.
McCulloch, Poulan & Wen; recommend 40:1.
1 gallon of premium fuel to 3.2 ounces of quality 2-cycle oil.

I just need to know if all gas weed eaters use the same gas/oil mix thanks

All 2 stroke motors use more or less the same oil/Fuel mix, BUT You MUST know the exact amount for your particular engine. I believe for your motor it is 40:1.
The commonest Ratios are about 5% (20:1) - 6% (17:1) and newer motors are usually 2% (50:1). I have also included 3% (32:1) because many tuned motors use this ratio.

I need to find out gas to oil ratio on 6.5 hp craftsman lawn mowe

This info is available at any dealer or repair shop. I would recommend contacting them to be sure. The lead says mini-tiller but your question says lawn mower. The 6.5hp motors, as far as I've dealt with were 4 stroke which means no mixture, but check with a dealer or shop, they'll know.

Waht is the engine oil to gas ratio for a mini tiller

The fuel ratio is determined by the oil and not the machine. Not all

oil is the same. When a manufacturer recommends a fuel ratio,

they are trying to direct you to the oil that they offer for sale. Over

the years 2 cycle oil has been offered in 16:1, 32:1, 40:1 and 50:1 .

Unfortunately for the user it is easy to get confused when selecting

oil. It is not difficult if you just think about it. There are two major

differences in 2-cycle engines. There are water cooled and there

are air cooled engines and the oils are entirely different. Water

cooled (outboard) engines run at much lower temperatures and at

much lower RPM's. It is necessary for outboard oils to burn during

the combustion cycle. In this situation the oil turns to smoke so

that the oil is not deposited in or on the water. Air cooled engines

run at a much higher temperature and must not be used with

outboard oils. In an air cooled engine the oil should leave the

muffler in liquid form. If the oil turns to smoke it is not able to

lubricate the engine and a very undesirable carbon deposit is left

behind leading to engine failure or stuck piston rings.

Since a top quality mixing oil will cost $12 or more for a six pack

(that comes out to well over $100 a gallon of oil) there is little

wonder that so many companies want a piece of that pie. Cheap

oils no bargain even if it is free. If the oil says it is for outboards,

lawn mowers, string trimmers, and chain saws, they are telling you

that they know nothing about 2 cycle engines and only want to take

your money.

You should choose an oil whose brand is that of an engine

manufacturer. Obviously these companies are not in the oil

business but they want to make sure that they do not cause

warranty claims from an inferior oil. The life of you engine is

dependent on choosing a good grade of oil. You should pick an oil

that you trust and that you can purchase on a consistent basis.

Unlike gasoline, oil does not deteriorate with age. It is better to buy

enough to last you a year or two than it is to change brands every

time you run out.
