steve.sharratt Posted February 27, 2023 Report Share Posted February 27, 2023 Hi All, I have both the Lister parts book and Instruction manual but be b*ggered if I can find any reference to how much oil a JP3 takes. I want to order to oil but don’t know how much I need. Does anyone know? Link to comment Share on other sites More sharing options...
James Owen Posted February 27, 2023 Report Share Posted February 27, 2023 If it's dry sumped then that will depend on the size of the tank. Link to comment Share on other sites More sharing options...

frangar Posted February 28, 2023 Report Share Posted February 28, 2023 If it’s dry sump with the lister copper/brass tank I’d day around 42 litres. My JP2M is 38 litres ish. And you need to allow for a bigger sump length…it might be dry sumped but there’s a gallon or more of oil still in it. Link to comment Share on other sites More sharing options...

I have ordered 20 litres and will see how I go. Link to comment Share on other sites More sharing options...

I converted mine from dry to wet sump, as I didn't have an oil tank. I just poured the oil through the opening created when I took the side door off until it was at an appropriate level. I had already made a dipstick, so I marked it at 1, 2 and 3 gallon levels for checking purposes. Initially I put in 3 gallons, but as I put a squirt of oil on the valve gear every day, I now fill to 2/12 gallons and the daily squirt from the oil can gradually tops up the sump. 33 minutes ago, steve.sharratt said: Cheers.

I used to use Morris's, but I now have a paper oil filter in the sump so that I can use cheap ( well, not really, perhaps cheap-er) Halfords 20-50.

I do plan to take off the side door. Does it have a gasket or just use cement? I have been have some oil issues through the exhaust and I suspect overfilling so I will be watching that closely.

monkeyhanger Posted March 13, 2023 Report Share Posted March 13, 2023 It should have a gasket.---if you can get one! Be VERY careful removing the side door and you may not damage it. I bought a roll of gasket paper and make all my own. Link to comment Share on other sites More sharing options...
