What Are the Benefits of Low Ash Oil?
What are the benefits of using "low ash" oil? I have some Mobil 1 low ash for my Mercedes diesel. Can it be used elsewhere?

Low ash oils typically are used for diesel vehicles that have a DPF (Diesel Particulate Filter) so the carryover oil that makes it into the exhaust system does not foul the particulate filter. We recommend you use the low ash oils for these applications. In the future, low ash oils will probably become more of a standard and will be acceptable for use in other applications as well.
