I know what you are saying hora thats why i have moved it to a new garage and want this:
OIL CHANGE PROCEDURE ON ALL DV6 ENGINES
It is necessary to follow a specific oil change procedure on all DV6 and DV6U engines so as to ensure that no used oil remains to mix with the new oil.
The following method must be used:
• The engine oil temperature must be at least 50°C :
– the engine oil temperature is considered to be at 50°C when the water temperature indicator is between 80°C and 90°C or the cooling fan has cut in
• ensure that the vehicle is level (side to side and fore and aft)
• remove the oil filter to allow the circuit to drain completely
• remove the oil filler cap and the dipstick
• remove the drain plug
• allow the oil to drain by gravity for at least 10 minutes (DO NOT USE SUCTION METHODS)
• fit a new oil filter
• refit the drain plug with a new sealing washer
• fill the engine with quantity of oil recommended for the engine
• refit the oil filler cap and the dipstick
• run the engine at idle until the oil pressure warning lamp goes out (about 1 minute)
• wait 5 minutes
• check the oil level using the dipstick: the level should be as close as possible to, but not exceeding the maximum mark (1) so as to be between (1) and (3)
For information, the lower mark (2) = Min (0%) the upper mark (1) = Max (100%) the intermediate mark (3) = ¾ litre.
