Can i use zmax micro lubricant while using synthetic oil or it has to be used only with conventional?

zMAX will be compatible with conventional as well as synthetic. Don't worry. In fact, according to their studies, it does not even mix with the oil. Their claim is that the product soaks (i.e., gets absorbed) into metal surfaces. I have given you the link to that below.





So if you believe their claim, go ahead and use it with any type of oil. Be aware however that many of their claims were heavily challenged by the Federal Trade Commission some time back. If you are paying extra for synthetic oil, yous protection will be superior regardless that you may not need to pay for this. Having said all that, I have used zMAX myself in the past with Mobil 1 5W30 and 0W30. Did not notice if it helped, but definitely can't say it harmed either. I think you are pretty safe to use it if you want to.
