Synthetic oil

I know I ran full syn in my 03 Dodge Ram and would lose a quart before a oil change in which I would go 5000 miles. I would have to add here and there to make sure it stayed full. Put on brakes one day and it was so low the oil light came on!! Syn oil is to expensive to just keep adding. My boss had the same problem using syn. I have switched back to conventional motor oil and don't have to worry about it any longer.....it stays full!

The engine doesnt leak at all so it has to be burning it.

I understand the pluses of it but it isn't worth a damn if it will not stay in the engine!
