In the past 10 years have mainly used Rotella because it still had ZDDP additive. However, Shell has reduced the amount of ZDDP additive so I increased my amount of additive. 2 years ago my engine was getting tired at 67,000 miles and I had the opportunity to have the engine rebuilt. After we took it apart it was sent to the local machine shop. Lamont indicated that the engine was in excellent condition with all parts within specifications including crank, cam, valves, etc. He said someone took very good care to keep the engine running with good oil, and changing it regularly. However, the cylinders were in need of .20 over which is not unusual for the age of the block and the crank was cleaned and polished It was reassembled with the same major parts and runs very nicely. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif;color:#1F497D'>I have not believed in buying high priced specialty oils for our engines or gear boxes when good old DINO or Conventional oil is good for them, of course, with an ZDDP additive.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif;color:#1F497D'>I have used the same ZDDP additive for years because the distributor I knew always had it in stock. When he went out of business, I bought his stock. The directions are simple add 5 oz. to a 4 cylinder engine so I used 7 oz. for our big 6 cylinder engine and at every oil change. I am using the last bottle of the additive now and will have to switch to another brand additive in the future.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif;color:#1F497D'>On the other hand, in my original transmission, the conventional oil was recently changed to Red Line MT-90.
