    Last year i started running synthetic oils in all of my 4 cycle engines, i love the stuff. A couple of weeks ago i heard someone say that once you run synthetic oil in your equipment that you cant put regular oil in after you have used synthertic because it bubbles and reacts. is this true or can i still put regular oil back into the machine.
    I at first thought that it was a way to sell more of the synthetic stuff but id thought id hear your opinions first

    Absolutely you can put regular dino oil back in. You can even mix most synthetics with dino oil, they are compatible in most cases.

    I switched back on a car I had, 2 oil changes before I sold it, no problems with it. Sold it to mother-in-law, she drives all over the place.
