Bilsport
A car magazine in
Sweden
Overview
Bilsport has taken a closer look at
XcelPlus (tested while under private label,
same formula). In order to carry out a comprehensive test, we turned to
Sweden's most advanced motor - testing establishment -
Nordisk Motortestcenter in
Vasteras, with it's
enthusiastic boss, Birger
Jonasson. The center is fully -
computerized and is combined with a rolling track ( 4
wheels and a fly-wheel capacity ). There were three test cars, a 1985
Opel Rekord 2.2 L, a
1985 Volvo 245 GLT and a 1980 Saab 900 Turbo S. The
Opel registered 7,100 kilometres; the Volvo ( a
taxi ), 51,600 kilometers and the Saab 149,390
kilometres.
The Volvo's engine and differential were treated with
XcelPlus after the first test run. Even
the front wheel bearing was cleaned and re-greased with
XcelPlus grease.
The
Saab's engine and gear box were treated
and so was the Opel's
engine, gear box and differential. At the follow-up test on
all the cars, a clear reduction in
in fuel consumption was noted. At a
steady speed of 97 km / hr, the
Volvo's
consumption fell by as much as 17.6 % - from 0.084 L/km to
0.0723 L/km. The car travelled 10,670 km between tests.
The
Saab's consumption fell exactly 10 %
at an even speed of 95 km/hr - from 0.0823 L/km to
0.0740 L/km. The car travelled 4,240 km between the two tests.
The Opel was driven only 1,730 kilometres
between the tests - far too little to achieve a complete baking process.
However, the fuel consumption fell at a
steady speed of 95 km/hr by 8.7 % from 0.0753 L/km
to 0.0687 L/km.
A new test of the Opel which was carried out
after a further 1,650 km showed that
consumption had fallen to 0.0667 L/km or by
11.4 %.
Great precision
In order to eliminate the human factor, special fuel gauges were used by
Nordisk Motortestcenter
for the tests. The gauge is made up of a pulse-meter (for pistons through
which the fuel must be forced). Each pulse represents 0.667
cL.
Then we measured how many pulses were needed in order to travel 2,000
metres at a constant speed of 95 km/hr or alternatively 97 km/hr.
When the milometer of the testing track had reached zero
the pulse meter disengaged automatically.
The same test was repeated until the number of pulses was established.
Another interesting finding was the coasting from 100 km/hr to zero. On
all three cars' driving wheels, there were notable improvements.
Take the Volvo as an example. Before the PfL
treatment, the left rear wheel coasted 629 metres. At the second test 1,021
metres were recorded: an
increase of
62 %.
The figures may seem both surprising
and sensational, but the tests in the U.S.A. and Great Britain show similar
results.

Comment:
Engine and gearbox is treated with
XcelPlus. At the second test, the rear
wheel-bearing was re-greased with
XcelPlus grease. Despite only twenty kilometres on the testing track, the
coasting capacity increased considerably.
*The peculiar value for right front
was caused by a faulty brake.

Comment:
Engine, gearbox, rear axle, were treated with XcelPlus. After 1,650 kilometres driving, another test was carried out. Then the
fuel consumption had decreased
to 0.0667 1/km, i.e. by 11.4 %.
the coasting level on the rear wheels increased
by a further 10 %.

Comment:
Engine and differential gears are
treated with XcelPlus. The front wheel bearing
was re-greased with XcelPlus Grease. A new test was carried out after an oil and oil filter
change. The same excellent results were obtained: XcelPlus maintains
its effectiveness even after an oil change. |
