I have a ed 30, currently on the long-life regime.
My background is - I am an Engineer in the forces (20years) on Rotary Wing Aircraft.
Now I have read up on the long-life service regime, 24 months or mileage based dependent on driving style. The oil is specially designed for this.
But with normal usage rates of anything up to 1 litre/1000Km, then concievably the oil you start with is not the same oil you finish with.
Having seen the way oil can and does break down, and lose its properties, then I feel slightly uneasy about leaving my Pride and joy at risk in this way.
Has anyone changed from LL to the STD regime?
Cheers
