Do I need to add oil to the gas? - Homelite 'Yard Broom' Leaf Blower

there most likely is no need to replace the oil as oil travels with the gas
it is normally put in through the compressor but the amount is critical as excessive oil will block the TX valve
now that you have replaced the evaporator, take it to an auto ac specialist shop , have the system evacuated right down , any oil required to be added and the correct amount of gas to be installed

??? Take a gallon gas can, pour the I/2 gallon oil/gas mixture into it and then add the correct amount of undiluted gasoline to the correct mixture. For instance, if you need a .2 oz/I/2 gal ratio then add 1/2 gal gas to what you already have. Remember, it is always better to have a little too much oil than gas.

The amount of oil moving with the gas is minimal as it is only what passes the pistons as lubricant that travels with the gas. The receiver dryer catches most of the oil that is moving. New compressors have the correct amount of oil so if you have the need to add oil check what is in the dryer and that will all that you need to add. If the system has excessive oil in it you will experience problems in the tx valve as the oil blocks up the opening.

Mix the oil and gas together first.
Or you can add some gas into tank, then add some oil, then add more gas, then bit more oil ... so oil-gas mixture is uniform.

Find out how many gallons your motorcycle tank holds. Do a little research on the manufacturer and model of your dirt bike. Also find out what ratio between oil and gas is required. Then, do a little math, and find out how much oil to add to each tank. Add the oil. Then add the gas. Adding the gas last will help stir up the oil in the tank.

If the engine is 2 stroke you need to mix 1 part 2-stroke oil to 50 parts gas, i.e. 2% oil

on the gas filler cap (if 2 cycle) there may be some writing telling the fuel oil mixture ratio. usually 40:1, if this is a 4 cycle engine, you don't need to add anything but if you are going to keep the sae gas in it over winter or for a long time without use, you should add some "gas treatment" available at any automotive parts store, this will keep the gas from turning to gel. other additives to gas are usually a waste of money.

I think you are saying that this is a 2-cycle motor (like most gas trimmers), that you already use a gas/oil mix, and you want to know how to add oil to the motor crank-case. If this is your question, then the answer is that you don't add oil to the motor. There is no place to add it. Unlike a 4 cycle engine (like in a car or most lawn mowers), the oil/gas mix is fed through the crankcase and is used to lubricate the engine, then is also used as fuel. good luck, Al K

You need to make your gas:oil mixture 50:1. 2-cycle oil bottles have instructions that tell you how much gas to add to them to make a 50:1 mixture.
