As of today, January 24th, 2017, there will be no further updating of "The Motor Oil Bible" ebook, and there will no longer be a charge for the longer "updated" edition (which is no longer fully up to date).

Although the vast majority of the information within this book is still very useful and accurate, there is too much of it that has become a bit outdated as the oil industry has moved forward in recent years, and I simply do not have the time to invest updating the book (especially since this is no longer my field of occupation).

Not enough people have a desire to actually pay for an updated edition to make it worth my time to tackle the update. Therefore, there will be no more updates, but, on a positive note, you no longer have to pay for the current full version of "The Motor Oil Bible". It is available below absolutely free.

It's been a fun ride. I enjoyed it when it was still my journey, and I am happy to have been able to educate so many people about motor oil and filtration. I'll keep this site up for as long as people still find it useful, but I no longer have the time or inclination to keep it updated. It's just not profitable enough to invest the kind of time it deserves.

Motor Oil Bible Ebook - Now Free

If you happen to want the book in paperback format, it can still be purchased on Amazon. However, just be aware, the paperback book is not any more updated than the electronic copy below. The information is probably about 5 years old now (last update around 2011, I believe).
