Some more testing results on MPG-Pills:
The testing vehicle is a 1993
Volvo 460 GLE, with 2.0L benzine engine that has been fed with the MPG-Caps for 3 tanks incl. conditioning now.
The tank's volume is 60 liters (15.85 Gal.). I have also figured out that I'm adding a bit less to the fuel than on the instruction but still the results are becoming visible.
The vehicle is only driven within the city limits (almost no highway),
prior to the MPG-CAPs the consumption was:
12.7L per 100 km - (3.35498 Gal. per 62.1371 Mi.
[18.52 Mi. per Gal.])
after the 3 tank the consumption is:
11.5L per 100 km (3.03797 Gal. per 62.1371 Mi.
[20.45 Mi. per Gal.] ).
Which gives a nice decrease in benzine consumption by 9.44%.
I have added the correct dose with this tank and will report when the tank is empty.
