Dunno how confidential this is, but a good source advised me that VW tested the first bit and the last bit of bulk oil coming out of a tanker that was dropping off bulk oil. The first bit was dark with additives that settled down, the last bit had insufficient additives. I know, not all additives settle, but VW was looking at premature engine failure and premature oil use (burning, smoking) and issued something to all its dealerships. All bulk oil ist verboten. The only way they can use bulk oil is in small tanks with a stirring mechanism going 24 X 7. Or, a small tank that gets a gallon added, from gallon (or smaller) containers, every time a gallon goes out. So they'd stock a thousand bottles of 4.5 quarts or whatever, and every time they did an oil change on a car, they'd pour more into the holding tank.
Furthur, another car company (I might say which via PM, but saying which wouldn't be too good for my source...but it's not a German company) got ahold of this memo and is looking at dictating the same rules to all of its dealerships.
So it seems a thorough study shows bulk oil can be awful for a car.
Comments? Anyone hear anything similar?
THANKS!
