Re: What Oil do you use?
Walleyehead:<br /><br />I use synthetic lubricant in my GMC Jimmy but adhere to the manufacturer recommendation of 3 months or 5,000 kilometers in ultra severe conditions or 6 months and 10,000 kilometers in severe conditions. <br /><br />In Europe Mercedes and Volkswagen claim that with synthetic lubricants and newer and improved engine engineering you can go up to 24 months or 25,000 kilometers without an oil change! Perhaps my Vortec 4.3 will outlast the transmission and rear end drive, but I have no other means to prove it other than with motor oil analysis and a good interpreter.<br /><br />Synthetics were invented and used by the German Army in the Russian campaign to impede that the oil in their tanks to become gelly during the winter, even with synthetic lubricants, they couldn't win as their logistics were insufficient and the Russians fought with their lives.<br /><br />But in terms of two stroke lubrication I have no other means to assess the importance of synthetics other than what the manufacturer says. If they could break down faster after being expelled from the motor and cling better to the metal parts of the engine than conventional motor oil that would be the real success of the synthetics. But I will only trust the results from an independent laboratory that will do the tests in a scientific manner.<br /><br />And if this independent laboratory wants to buy my 69 Chrysler to make the tests, then you can contact me here.
