“2020 was the year we picked to do the lap around Oz but from the outset I decided to have an extra insurance policy in the form of Fuel Doctor. Our vehicle is a 2018 Isuzu D-Max so didn’t have too many K,s on the clock but it was my resolve to use Fuel Doctor from the outset. Although not using every fill I believe it has assisted in easy starting (still running original battery) and no nasty black cloud from the exhaust. Our first real test of Fuel Doctor was when we met up with friends in Adelaide when I was presented with an edge trimmer that would start but die ounce the throttle was applied. Out came the Fuel Doctor and within minutes it was running like new. Next was a small quad bike of friends in WA, very hard to start but again within minutes of adding Fuel Doctor it was running beautifully. Fuel Doctor was in their kit the very next day. Last but not least our 15 Hp Yamaha outboard has not skipped a beat even after long layovers. Best thing since sliced” bread.” – Owen Davies from Queensland
