Makes a difference IMO
Adding into an almost empty diesel tank and then filling up seems to make a real difference to engine performance - in my opinion

As described
I poured half in my oil tank and half into my fuel tank and it made my engine run smoother

Started using Seafoam about a year ago when my 2016 Toyota Camry was burning oil. I was using about a quart of oil every 1200 miles. I started putting 5 oz in the crankcase and the remainder of the bottle in the gas tank 200 miles before every 5000 mile oil change. After two treatments, the oil consumption rate is about a quart every 6000 plus miles. Reduced engine noise and improved performance. The Camry is going on 340,000 miles with all original parts. It works for me.
