“Herewith my results with a caravan cruising to and from Warmbaths  at approx 105 – 110km/h with my 2 liter Nissan X-TRAIL Petrol 2008 . To Warmbaths with unit fitted: 116.6 km’s used 12.46 liters @ 9.36km/l From Warmbaths unit removed: 114.2 km’s used 14.51 liters @ 7.87km/l. This equates to approx 19% improvement – excellent!!! The above was all highway and where I experienced the most pleasure was the increase of torque on the long gentle uphill’s. You simply don’t have to engage 4th gear as much with fuel saver unit fitted.” – Dougie – Centurion
