new batch
« on: July 10, 2010, 09:41:51 PM »
This hot summer were having in the UK might be a good thing if my Lister is telling me correctly.
Sine I've finished burning the two stroke oil I had I've started burning the next batch of old engine oil I picked up from a couple of garages.
I always remove the compression blanking plug and clean off the carbon from the injector tip before the next run ,but since the hot whether and the next batch of  oil there has been no carbon for over a week and a half.
So I don't know if its the oil or the hot whether?
I am going to reduce the a mount of petrol diesel mix and see what happens.
I am on the look out for a regular source of petrol diesel mix from cars filled up incorrectly and then pump out by people like the AA but I was told by an AA patrol man that it had to go to an authorized company.
Has any one got any thoughts

I was fortunate to pick up 10 gal of RUG/Diesel mix. It seems one of the welders wife's accidentally picked up the green handle. It is being used to the thin the used hydraulic oil that also came from work. I've been dubbed the waste oil guy at work and am getting more than can be used!  ;D The hydraulic oil starts and runs well, however it does leave similar carbon deposits on the injector to what you describe. On my engine the COV plug is difficult to remove and the injector comes out easy so that is how I keep it clean.

You bring up a good point regarding the heat.
Many owners of Listers and Roids do not have a thermostat installed in the cooling system.
Perhaps hotter running (a 190f thermostat) would help reduce carbon when burning WMO or Hydraulic oils ?

On an auto-siphon cooling system without a thermostat, the engine could run cold for a long time. Prime conditions for carbon buildup.

There is a 180 f thermostat in mine. I've considered changing to a 190 or 195.
