A “rethink” of the Fram Sure ( oil ) Drain

[aldive]

I just started doing it too. However, I use an entire quart of fresh oil.

I use an entire quart as well.

Have you ever used one of those oil detergents?

Not I; nothing goes in any motor of mine except synthetic oil.

I have been thinking about switching to synthetic. If I do, can I just change the oil like normal, or do I have to flush everything out real good. Will it hurt if a little dino oil gets mixed with synthetic?

All you need to do is change the oil as normal.

Goof luck....

Every syn oil I have seen states that the syn oil is 100% compatible with regular (dino) oil. You could mix them together if you wanted (I'm not suggesting that you do though) and it should not cause any issues.

re: Flushing with new oil

I have done this when opening the engine up (i.e. changing the valve cover gaskets or replacing the timing chain) but I don't think it is necessary for a normal oil change. It won't hurt anything, but I don't see that much of a benefit either.

re: Using a Oil Flush product

I have seen that some people on the Oil Board have a product that they like, but again, if you are changing the oil regularly and using quality oil (esp syn oil which is high detergent) I'm not convinced that there is a big benefit to the oil flush products.
