I did the first oil change to me yesterday after I purchased a 2014 Acura TSX (K24 engine) with 25k miles. Since the prior OCIs were around 7k-ish miles but 2-3 years on average I wanted to start fresh and since VRP is the talk of the forum and affordable I decided to run that along with a bottle of HPL EC30 I had lying around.
I do not have the depth of knowledge as some of you so I’m curious how I - or any of you - could be convinced in your own car that 4 OCIs worth did “work”. Since HPL EC30 is part of my initial mix and since I asked Dave on its usage in another car I used it in, I will be doing a quite short initial drain/refill 2000-ish miles from now per his recommendation and changing the filter; will be cutting open the old filter for inspection. What else, short of doing a full tear down, would be a good test/evidence for its purported effectiveness after 4 normal OCIs?
