Rhino results, on an 18,000 mile 2.0JTDM (2010, 3 years old)
Computer Mpg: 36.0 Actual: unknown
Rhino triple dose
Computer Mpg: 37.0 Actual: 38.5
Rhino double dose
Computer Mpg: 37.5 Actual: 40.8
Rhino single dose
Computer Mpg: 42.0 Actual: unknown (tank incomplete)
So the MPGs have been going up with each dose of Rhino, but the biggest increase by a long way has been moving on to the single dose. I imagine that this is because the concentration of octane and cleaner in the triple and double doses is too high for the engine to maximise efficiency, but it seems that those high doses have had some positive cleaning effects.
The engine idles quieter, and now it's on the single dose it's pulling harder, most noticeable at low revs (where it might previously have bogged down), but also at the mid-top end where it is pulling harder than it already had been doing. So that suggests torque is up right across the rev range.
Most interesting of all is that this computer always underestimates the MPGs it has acheived. It's the only car I've ever seen that does more MPGs than it claims!
