I will assume you have the correct damper (vented or non-vented) for the application.Most people I know fill the dash pot damper tube by filling it up to the top of the tube. That is over filling. As soon as you insert the damper an amount of oil is displaced. When you remove the damper the oil level looks low, but it is not. To test the oil level insert the damper into the tube. At first the damper will go in easily, then you will sense resistance as you continue to insert it. That point is the level of the oil. Unless you are racing the car you should use the recommended oil for this application. Having to fill them every 2 tanks if gas, if they are actually loosing that much oil, is excessive. I would remove the dash pots, piston & damp. Examine them closely. Gary

A few years ago as my BJ8 carbs had been so molested over the years by numerous PO's bought a pair of new HD8 from Burlein.
They came with brass capped dampers.
For the life of me, cannot see any part numbers on the dampers
I am curious/suspicious as seem to have to top up more frequently than I remember with previous SU cars.
At least after every 2 tanks of gas driving time.
Not accurately checked standing time with no driving.
Where does the oil go ? Makes no difference what grade that I use.
Thoughts ?
