change oil

[phenoyz]

The most common factor in sludge buildup is mineral oils combined with a lack of maintenance by the car owner combined with harsh driving conditions. But this isn't true in all cases. For some reason, a 2005 Consumer Reports article discovered that some engines from Audi, Chrysler, Saab, Toyota, and Volkswagen appear prone to sludge almost no matter how often the oil is changed.

For their part, Toyota have the dubious honour of having the most complaints about sludge buildup in their engines - 3,400 at the last count. At the time of writing there is a class action suit going on against them. Details can be found at [url]www.oilgelsettlement.com
