Truth is good; truth will set you free. Is there anything more you could add? Not something I would use in any of my vehicles as they are not DI and clean without the use of additives. Simply good quality oil and filter with a reasonable OCI for the conditions I drive. IIRC your 08 Titan mentioned isn't DI either. We had a 10 Titan in the stable for about 8 years and it was not DI either.
I'm not challenging you on the gas mileage increase statement as I bet you did see an increase. But that wouldn't be the Motorcote directly, that would likely be the Motorcote breaking up some deposits. That can be good and bad depending....How long have you been using the Motorkote? If you haven't I would make sure to cut open the filter and check to see what is being caught. If you would, please share filter pics with us. I'd be interested to see the results.
Thanks for posting the video.
