You break in a car on dino. After the break-in period, you can use synthetic. You can switch back and forth all you like, mix them if you want. They're completely compatible. Saying they're not is 30 yr old advice, because that's about when synthetics were made to be compatible with dino oil. So, unless you're pouring 30 year old synthetic into your car, or you have 30 year old synthetic in your car, that information is just plain FALSE.
yea a mix is a pro blend
