Use only Classic high detergent style Oils such as 'Castrol Magnatec' or 'GTX', do not use fully synthetic or oil additives.

If your engine is supplied with the Oil Pump base plate fitted, you can be assured that a priming agent (Vaseline) has been packed into the oil pump gears to ensure trouble free priming, if it has not been fitted then you will need to do this yourself to get oil to turn the engine over if the distributor is not fitted (the distributor drives the oil pump), but if you forget and the distributor is fitted you will need to re-prime the oil pump before starting.

The best way to do this is not to worry about starting the engine but to remove the plugs and the coil lead and have a highly charged battery available. The engine (with the distributor fitted) will crank over at a speed that should allow the oil priming to be achieved in seconds (oil Light out and a visual check), and, unless you remove the oil pump again, no further priming should ever be required.
