Hi,
after my last post on this subject, even though the old oil level was on the top mark on dipstick, I also got an 'OIL LEVEL' warning displayed for a short duration.

I have changed oil and filter but am still getting the 'Oil Lack' warning frequently, even after putting in an extra 0.3l.

Having got two different warnings - Oil Lack & Oil Level, surely they must come from different 'senders'. The owners manual confirms engine oil for both, so have I got a blocked oil way or breather, a duff pump?

From previous experience, the red oil warning light is controlled by a pressure switch and operates at some 10 - 15 psi. What sensors control operation of these other two warnings.

Thanks

Fairly sure oil lack comes off a sensor on the side of the sump,right hand side as you look from above. Not sure if it is same as low oil, but I am sure it is seperate to the pressure warning on the dash. Think the low comes on when its about a litre short and lack .3 after that

Do you have oil in the spark plug wells??? If your losing oil then cam cover gaskets are a popular failure as a result of failure to clean breather system

Hi,
sorry forgot the TD in title, a tractor.

There is no useage of oil. The oil level before I changed it was on the top mark on dipstick. After changing oil & filter the 'Oil lack' warning still comes on frequently. It and the check light do go out. Thinking that the light may have gone out when on a decent, braking or tight l/h turn, I put an extra 0.3 litres of oil in - slightly above top dipstick mark, but still 'oil lack' warning.

I just can't understand why, as oil level is up, the oil lack warning shows. The car was standing for a year before I got it. I assume that the sender is a float in the sump, or is it some pressure sensor - possibly indicative of a duff pump or blocked oil way. Anyone any ideas?
