Lets not forget about those who think Transmission fluid is "filled for life".

Just thought it would be an interesting read for those who think Synthetic oil lasts forever:

"Earlier today, I saw a failed engine on a Jeep Grand Cherokee that is interesting to consider. All the engine bearings failed. The bearing inserts saw high heat. They and the connecting rod caps are black. The crankshaft is ruined. It looks like the fix is a new long block. The engine was using a synthetic oil which starts with the letter A and is distributed by independent distributors. The owner had the idea that this fabulous synthetic oil is good for many, many thousands of miles of around-town driving with filter changes every 6 to 7 thousand miles. The oil had 27,000 miles on it at time of engine failure. The tech believes that the engine failure is directly related to the owner's failure to change oil on a regular basis."

even A's best oil isnt rated for more than 25k in non-severe service.....he probably had one of the cheaper formulas for not-so-extended drain interval, and thought "it doesnt matter" <------ very famous quote, u here this alot while discussing the topic of synthetic lubrication ....

here's one that mike (specialdelivery) and i always laugh about, caus this guy we know recommends this mystery crap.....lol......(new york accent) "If you put IXL in your........you dont even need motor oil.......DOESNT MATTER !" LMFAO "If your "A" stuff is so good, then why cant u drain it all out and drive to Sarasota.......DOESNT MATTER !" LOL LMFAO

EDIT: oh wow, i didnt even notice how old the thread was.......oh well the facts still stand....

(disclaimer) (I have used "A's" diesel oil in my 2 diesels, for over 200k miles combined, over 11 years, driving many many deliveries......i do every 15k on the diesel oil.....filter every 5, its awesome...
