I just put a whole bottle of oil in. It blew white smoke both before and after the addition of oil.
What kind of oil and where did you put it?
White smoke is normally water vapor and blue smoke is oil. You dont have any water in your engine unless your gas had water in it. Was it out of oil or did you drain the oil and refill it?
Make and model of your mower could help.
Well if you dumped a quart of oil in and didnt drain any out, as in an oil change I would say your engine is burning a lot of oil and that is the smoke you see. These mowers are so inexpensive most of the time it doesnt pay to fix them. Worn piston rings and valves will let crank case oil into the combustion chamber and it will be burned as fuel and will make blueish white smoke. All you can do is live with it for now and buy a new mower or if your deck is really good change the engine out. It will keep getting worse and if you dont keep oil in it will get worse fast.
edit:
In thinking about it you could also be over full of oil if you dont understand how to read the dip stick. When you say you can look down the hole and see oil is the oil close to the top or down around where the lines are on the dip stick?
The last time I refilled my lawnmower, after I drained the oil, it took 30 ounces of oil, leaving two ounces in the bottom of that quart of oil. IMHO that is a poor design and it makes it complicated and a waste of oil.
Find the modal number, look up the amount of oil it should take, change the oil with the correct amount, measure with a yellow pencil and record that for future reference.
Oil will burn down to the correct level or a little above but the spark plug will likely need to be cleaned a few times.
My 25 year old Snapper ( Briggs & Stratton engine, 5HP) has been burning oil for a while. I just recently picked up an oil additive meant to stop oil leaks (Bardahl somethingorother) Too soon to know if it helps, but I will let you know.
Also make sure you are using SAE 30 oil. It is not the same as car stuff (not 10W30 etc.)
OP,
My neighbor had a pressure washer that his son had overfilled with oil because he had trouble reading the dipstick. It blew white smoke. Removing some oil was the cure.
Where do I buy specific parts for a lawnmower like spark plugs, air filters, etc?
