Your lack of understanding and apparent lack of experience with DI is ridiculous.
Strong fuel odor in oil is NOT normal. It indicates the presence of fuel (you know...gasoline) in the oil. Having paid for one UOA with the oil in this condition, it was confirmed that fuel was present in the oil and shorter intervals were recommended by Blackstone. So I don´t see the need for spending $35 every oil change when the nose can detect it. It happened CONSISTENTLY when my Ecoboost was seeing only short trips. And predictably, when it was driven in a profile with longer trips where the engine was able to fully warm to operating temperature on a regular basis, the smell was either not present at all or mildly present. So it can be deduced that the presence of fuel in the oil is not as great. And so, I ran longer OCI´s when it wasn´t there or wasn´t very strong.
You see, your nose is an amazing instrument. It can collect data and your brain can analyze that data and make an analysis of that data. You can then make some decisions based on that analysis. It is very simple.
I think it would be fun to take a long trip with you and give you a little test. I would eat a bag of 10 White Castles and within a few hours, we would see if you are capable of making a decision to take action, such as evacuating yourself from the car, based on the immense amount of data data your nose would surely collect. In fact, it might be such pungent data that you would be tempted to vacate even while the vehicle is moving. I am sure you would then understand the concept. If not, then you can protect your pride and enjoy the clam bake.
