Changed the oil and filter yesterday. Last OCI, the filter showed a lot of carbon deposits. This time I used only Shell premium. Although this OCI is only 3k miles, everything looked amazing. The pleats on the filter are perfectly spaced.

I did make the switch from AMSOIL Signature Series to HPL Premium Plus PCMO, but could have saved some money and stuck with the Amsoil after seeing these results. Sample was sent to Wearcheck for UOA.

I dropped the gasket, so it has schmutz on it.

I stuck my borescope into the oil pan drain hole to look around. I was curious how much oil was remaining at the bottom. Best I could see, almost none. Here are a few shots from inside (engine has 13k miles). Ignore the date time stamp. These were taken yesterday.

Yeah, not much should develop that early but fun to peek inside. Filter looks flawless. You sticking w/3k intervals?
 
Looks good inside, but with only 13K miles it should. What borescope are you using, gives nice shots.
Got this one from Amazon. It has dual cameras and is articulated, so you can look just about anywhere. I like the length is not too long, so easier to manipulate. I have another that is so long it can be used in plumbing throughout the house. Also, its picture quality isn't as good.

Planning on sticking with 5k OCIs. After all the carbon in the filter on the previous OCI, I switched to only using Shell premium to see if it would help reduce the carbon. About 500 miles ago, I verified using Sport or Tow drive modes on the newer Pilots would prevent the VCM system from activating and my wife and I had started using only one of these two modes. Having made this switch during my Shell premium test, I opted to do an early OCI.

Besides only running in Sport or Tow drive modes, the Pilot will only be fed Shell premium. The owner's manual says use TT with octane 87 or higher, but Shell has proven itself to me.

Thanks for the cut! Looks great!

I know hot shoe Euro car owners love Shell V-Power, did you test 87 gas running the Pilot in Sport mode too as a control for carbon? Appreciate the info here.

No. I'm torn about trying it knowing how much the Pilot, and my wife, seems to like how it's currently performing. I may try weaning it off with every other fill-up using 87 octane Shell. It may just have been the Quik Trip I was using, although TT.
 
Everything looks great in the engine and filter!! No more carbon/soot in the pleats. Crazy premium fuel made that much of a difference.
 
I did something this oil change switching from Amsoil to HPL which I'd never done before. Our buddy, LSJR, recommends pouring a quart of the new oil through the fill to help flush out the old, acknowledging it's only going to get some along the way through to the drain hole, but helps cut down on the amount of residual oil, or as he calls it, cross-pollination.

Curious to see how much old oil may be pushed out before seeing the new oil, I set up a video camera to record the oil coming out of the drain hole as I poured through a quart of new HPL. Hint #1: don't blink.

Should anyone care to see how quickly a quart of oil goes through a Honda J35Y8 engine, it's posted here on my meager YouTube channel, which I use as a storage place for videos I may or may not care to ever watch again. Hint #2: the video is 1:40 long, going from a few remaining drips of Amsoil to HPL doing something similar. If you choose to watch it, the only guarantee is you will never get that time back. Ever!

What I failed to do was stick the borescope inside before doing this, so the pictures above are the after shots. The red-colored oil clinging to the heads of bolts is the Amsoil, and the brown-colored streaks are HPL, aka "skid marks".

What I learned from the exercise was it doesn't take long at all to blow through the cost of a quart of HPL with the very high likelihood the ROI is probably the worst overall percentage of any of my failed endeavors.

^^^ Yeah, the LSJr "quart of oil flush" is a total waste. If there are any sediments in the bottom of the pan that won't come out with a hot oil drain, then they aren't going to come out with an extra quart of oil put through the pan.
 
Here are the results from Wearcheck of the Amsoil sample taken via a pump through the dipstick hole a week or so before doing this oil change. It only has about half the mileage as the previous sample shown on the report, but looks like things are headed in the right direction.

I plan to run the HPL for a 5k OCI, but not do a used oil analysis until the following OCI due to the mixing of the remaining Amsoil (oil and deposits on surfaces) with the new HPL.

I agree that the LS Jr. waste a quart method is not needed. Why would anyone throw front $9 to $15 out the window?
 
I have done that quart flush method.... but it will be some leftover cheap half full containers of oil or a quart of Supertech.

I really only did that after a BG EPR engine flush just to try and rinse any leftover chemicals out.

I remember first time I saw it done on his daughter's car I thought, now that's hard core. Not something I would do, but imo in a 'similar/not same' realm as prefill, blowing/sucking on filter for adbv test etc. That said, agree more wasteful than anything else. Haven't followed it that closely but iirc it's only done on FF change.
 
^^^ Testing the ADBV for sealing integrity doesn't cost anything and is worth doing .... just do it in private. 😄
