Just use the fuel injector cleaner right before an oil change then and problem solved.
Its probably vehicle, driving, oil and fuel dependent. If the product thickens the oil greatly, its definitely not good for the oil at all. It has been the only time my oil went this way so I just will not use it. Sure it will clean my engine but it kills my oil which I really dont ever want to do.
If you're getting enough PEA from your fuel system into your crankcase and oil to significantly thicken it as you say, you have MUCH larger problems my friend! How are you proving this "oil thickening" anyway? Do you have the viscosity tested after each treatment? Before and after? How many times have you tested and repeated this?? I'm just not buying it...
