Reply to "What Oil to run in the Pantera?"

The bigest thing we were taught in college was you could go from detergent to non-detergent but NOT non-detergent to detergent. Detergent will break up deposits otherwise undisturbed by non detergent. The problem being most automotive oils do not put on their detergent qualities. I would gather from this that all have some detergent qualities but differ some what based on the type of additives used. For this reason it is important to pick one oil and stick with it as a different oil can cause problems down the road. This is not to say one oil is better than another, just that swapping oils can caause problems.
