An excellent article entitled "Comparative Analysis of Oil Filters" by Stephen Wynne was printed in DeLorean World Volume 7 No. 1. The article includes some very good photos of the insides of the DeLorean OEM oil filter and other after market filters, plus a description of the differences. This should be a MUST reading for ALL DeLorean owners. Copies are available in the DeLorean Store at: http://www.deloreanstore.com/ An index that includes this article and all technical articles that have appeared in the last 19 years of DeLorean World is available at: http://www.delorean-owners.org/dw/tech_index.html A wealth of technical information on our DeLoreans is available in the DeLorean World Special which includes ALL issues of DeLorean World magazine and an updated Technical Index is available in the DeLorean Store.
