2002 Honda Odyssey here (19.5 gallon fuel tank), turned 220,610 miles.
Car's been using 83 octane mostly from local grocery store brand blend. Very occasionally using Shell 83 (or 93) octane.
Haven't had the opportunity to inspect the pistons with plugs removed. Will do that.
Dumb of me, took me ~21 some years to notice this TECHRON cleaners. And i just had my recent oil change few days ago.
So, for next oil change plan to have the car on TECHRON at least a full tank or so before the oil change.
Question is, should i be going for HIGH MILEAGE, more "regular" uses?
Or, a COMPLETE version, of up to 2 uses before the next oil change ?
Thanks!
