thanks im going to plug it and then fill her back up all the old oil has gone clumpy in there

put like half the bottle of oil in and then check the dip stick. Keep adding a little at a time until ur at the gravy zone.

To give the engine a good flush just put 1-2 litres of diesel in the oil tank then let it idle for 60-150 secs at 2500-3500 revs until it reaches medium to hot on the temp gauge then swith it off and undo the bolt to drain the oil.
The diesel thins the engine oil and removes clumps of dry/compacted oil.

Let it drain for around 8 hrs then pop the bolt on and fill it with 4100 ml of old engine oil then start her up.
Let it idle it for 10 min then take it for a spin.
