Oil change Hi I am about to change my oil for the first time. I have a 6.5 craftsman lawn mower. I was told to use a universal oil.2.6 oz. (Echo Power Blend) I read the drections on the oil bottle and it said to mix 1 gallon of fuel with 2.6 oz oil. My mower was just about empty of oil. I pumped the mower several times and then pulled the rope to start the mower. It wants to start but won't, what should I do. Frances

STOP !

Your lawn mower is has a 4 cycle engine
It does not require oil to be mixed with the gas
The oil for the crankcase should be a 10W-30 or 10W- 40
NO GAS IN THE OIL
What you have is a 2 cycle oil that is mixed with gas for most weed eaters, chain saws, ect
Putting a gas/oil mix in your mower WILL severely damage it destroying the main bearings and could lead to an explosion or fire.
Please be careful

Craftsman 675 starts fine but runs rough all the time

I would suggest the following:

1. Either clean or replace the spark and make certain that the gap is correct;
2. Check the ignition wire for breaks or cranks, if found, replace the ignition wire; and,
3. Add about one (1) oz of carburetor cleaner to a full tank of gas.

2 or 4 cycle oil for a Ranch King 6.0 lawn mower? What kind or type of oil should use?

If you mean oil for the crankcase use need 4 cycle oil Ususally 30 weight and don't over fill Most small engine do not even take a quart only about 20 oz.

If you mean to mix with gas ( I doubt this) but then you need 2 cycle oil depending on the mixture usually about 3 oz to a gallon of gas (3.2 oz / gal = 40:1 ratio, 2.5 oz/ =50:1)

Hi - I have a really old very basic lawnboy - Says it requires 1/2 pint lawn boy lubricant per 2 gallons of gas!! Or 1/2 pint regular oil per gallon. Cannot find lawnboy lubricant, so which kind of...

You need to use a quality 2-Stroke oil in the fuel mix. Do not use engine motor oil. They sell the small (like 2.6 oz) bottles of 2 stroke oil at the Home Depot and Lowes garden centers. Small lawnmower repair shops have it also. It may say Echo or Homelite or even a store brand on the little bottle, but please,again, don't use oil that you use in the engine of your car....use 2-stroke only.

I cannot locate my manual; can you please tell me how to change the oil?

Simplest thing to do. Remove spark plug wire for safety. Remove oil filler plug. Tip mower to the side the filler neck is on with a bowl waiting on the ground next to the mower to catch the used oil. When empty, tip mower back upright and refill with 20 oz of 30 weight non-detergent oil. Put filler cap back in and check level. Replace spark plug wire. Thats it!

My craftsman rotary lawnmower wort start i changed the spark plug

a mower will hold 20 oz of oil. however most times it is changed you do not not get it all out. so only 16 oz is needed. if you overfilled the oil. this would cause hard starting. or did you have the mower tipped on it's side for to long, oil can sometimes seep past the piston out thru your intake valve and into your carb as well as destroy you air filter. you might get by with a new oil change and a carb cleaning.


also has this unit been sitting for a while does it have fresh gas. and No water in the tank/carb
