Oil

Can you mix full syn oil with semi syn oil. Also is there a problem from using semi syn oil & changing over to full syn oil at oil changes or vicaversa.

Now days you can mix the two with no problems, years ago or i should say decades ago thier were instances were compatibility was an issue between synthetics and fossils. As far as switching between simi and full synthetics on motor life or run issues no.
