I always thought that synthetic was a super oil and you could NOT return to the old stuff .

There is no incompatibility between conventional oil and synthetic oil - if there was, you couldn't have synthetic blends - but why would you want to go to non-synthetic oil when synthetic oil is definitely better?

And, about blends - I have never seen any blend that says what % is synthetic - 2 drops per quart?

My personal opinion is you'd do better to change oil every 4,000 miles with synthetic oil, rather than 'dino' oil every 3,000 - to keep the cost the same.

There are likely a hundred oil threads on this forum. This is the most unique. My take, stick with synthetic, buy a lot of it when on sale at Walmart or wherever, and change it every 3K to 5K miles. The cost difference over the long hall will be negligible. If you are crawling under the car to change the filter you may as well change the oil.

Fresh, top quality oil is the cheapest engine insurance you can buy.
