There's a snappy new moniker for Black Death now: sludge. The cause is the same as Black Death and it seems to be regardless of maintenance or mileage.

For their part, Toyota have the dubious honour of having the most complaints about sludge buildup in their engines - over 5,000 in 2008 alone. At the time of writing there is a class action suit going on against them. Details can be found at www.oilgelsettlement.com
Black sludge can be caused by a variety of factors... engine design, fuel quality, oil quality, never driving long enough distances to warm the oil through, oil getting too hot in turbochargers, whatever. My car (no not that one.... one from the other Swedish car company which had the enormous turbos) has a reputation for being sensitive for black sludge, and as such I only use high quality full synth every 20k and do all of the oil changes myself at a DIY shop. I have developed some mild trust issues when it comes to garages doing stuff to my car a few years ago, you see.Wage Slave wrote:Coligny wrote:Black or white sludge ?

Interesting. And a bit mysterious.
Black sludge - It can set in even when the oil isn't very old or overdue for change. Toyota engines of a certain vintage get a mention as being vulnerable. I did once come across this - I noticed SiL's Noah had a bit too much top end clatter for my liking and as she was due to take us on a 4 hour drive to the airport in it I had a look. And yep, there was some black sludge. The local garage put an oil change in it with some additive and ran it a bit. Drained it then put in fresh oil. It was fine but a close call and SiL was adamant that the oil had been changed by Toyota less than 12 months previously. It should have been OK.
Incidentally, does anyone follow the local recommendation and change their oil every 6 months or do you all follow the manufacturer's spec which is once a year or 15k or so. If I were doing 10k or more I would change the filter every year but as I do less than half that I change it every two years. I forget what the local logic on that is but they are constantly telling me it isn't really necessary.

Oil pressure is to an engine what blood pressure is to a vertebrate: the light comes on when there is none, and all of the bearings in the engine are no longer being lubricated. In that way it's almost literally like having a stroke or a coronary: it always does damage even though it may not be immediately apparent. I always keep an extra 1l bottle in the trunk just in case.

Yep, but the Missus didn't care. It was some 2 years ago and no problems have emerged since, so probably OK. But yes, nowadays I do have a bottle of spare oil in the trunk.
