In Reply to: oil loss on cruising????? posted by Paul on September 14, 1999 at 14:13:37:
: I have a strange problem with my `91 525i 24 valve E34 manual. When cruising around short journeys around town the oil level is o.k but as soon as i do long distance freeway driving for say a 400 mile round trip i loose about 1 1/2 litres of oil and the warning light comes on. I can`t see any leaks on the engine and no oil patches on the drive. the car has done 140,000 miles and has full service history. Please help!! Thanks in advance!!
The higher revs produce greater pressures and you are probably blowing your oil out somewhere because of worn seals or bearings.
