Just got a 2.2 diesel, and I try to check a few items myself eg air, tyre wear, washer levels and oil. I was always told when checking the oil to let engine cool as oil level will be as in sump but I was told recently that with a diesel it is best if the dipstick shows level halfway betwen low and max BUT I was then told check when engine is warm!! ie after a run, stop go inside wait a few mins then ckeck oil level and this gives a more accurate reading.
By the way I always had dipstick reading at 3/4's for petrol just to be safe.
Anyone have ideas on the diesel engine oil checking procedure? And why is it so expesnive for these diesel synthetic oils??
noah
