Valvoline Restore and Protect Fuel System Cleaner??

As I stated, Honda's J35Y8 engines are prone to carbon fouling with reports of related fault codes being thrown as early as 20k miles requiring intake valve cleaning. No doubt the design of the engine is the major contributing factor, but my experience with Quik Trip, TT certified, 87 octane has shown me that just because a fuel is TT certified, doesn't mean it's the best you can buy. My switch back to Shell premium was my attempt to mitigate as much carbon deposits as possible. Based on the last oil filter inspection, I'm satisfied my approach is working for me in our Pilot based on how we drive.

Just sucks that you need to pay that extra penalty for premium in something that should be fine on regular 87.

Costco 87 has almost as much detergents in it as Shell premium so that’s another option

Our closest Costco is 4x the distance to the closest Shell. Otherwise, I'd fill with them to see how clean the oil filter stayed. Also, we don't drive a lot locally, but take trips to Wisconsin about four times per year. Trying to find consistent fuel stops can be difficult, but I can tell you every Shell station we regularly stop at on these trips.

Just came from local Autozone. Bought 6, came home with 12. Should be good for the next year or a bit more if I do one per oil change.
