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.

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.


What petrol do you use in a lawnmower?

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.


Can you use 10w40 oil for your ryobi 4stroke lawnmower if the manual suggests 10w30?

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
