For most lawn mowers, especially those with a 2-stroke engine, the petrol and gas are mixed to ensure lubrication of moving parts. 4-stroke engines (as commonly found on ride on mowers), usually have the oil and petrol separated. If you have a 4-stroke engine, then you need to disassemble it and replace the piston rings to stop the petrol from leaking into the crank case.
probally bad rings.
Dump/siphon/drain it as best as possible and as long as you haven't tried to run it, you should be able to fill it with petrol and fire it up! The petrol will dilute the residue sufficiently.
Ordinary 87 gasoline, the same you put in a car. It depends if it is a four stroke or two stroke engine. If the engine has a separate filler for oil then plain petrol will do. If there is no separate filler the 25 to 1 petrol /oil mix should be OK.
I can't imagine that would make much difference. The different weights of oil affect the durability of the oil in the long term and its performance in high or low temperatures. hi just to let everyone know i went ahead and used the 10w40 oil instead of the 10w30 that is suggested in the ryobi petrol lawnmower manual and it worked perfectly i have a 140cc 4stroke petrol lawnmower model no RLM140SP thanks steed69
oil will run away from crankshaft and become dry on rod thus rod is is dry no oil rod breaks comes out side of block
Depends on which engine but most use SAE 10w30 weight. I recommend you use 100% synthetic oil in an air cooled engine.
The engine will overheat & seize due to lack of oil. A 2 stroke needs a fuel oil mix to lubricate it's moving parts.
Yes 10w30 is a good oil for snowblower or lawnmower.
Oil is petrol
If the wrong oil is used in a lawnmower, do not start it. Simply drain the oil as completely as possible and fill with the proper oil.
When you overfill oil in a lawnmower it will smoke when you tip it sideways while mowing,it has no harm
Petrol is processed oil.
