I assure you roberto it is probably healthier than your car, had been actually owned by a BMW tech for the last ten years. I drove that for 14 hours straight from Texas I will stand behind my statement. Slug is overkill, but truth is I wouldn't race anything in it.
Also to BMW_LVR I always think of things as if it were on my car, so distributors and timing chains apply. It was a simple list of stuff that wears and maintaince. How many times do you do pulleys and, fan clutches a year? Lol
Has any one read up on the Bentley manual in the maintaince list in the begining lol It's a massive list.
