Be lucid!

All this has been confirmed to me by the many additive analyzes of John Rowland himself, the Fuchs UK chemistry leader with his 33 years of experience. He even agreed to analyze the gears of my gearbox in his laboratory. For him and this confirms the well-known endurance of Citroën BE3 / 5 gearboxes, these damages are typical of the known side effects of chlorinated paraffin additives.

I informed the manufacturer of these conclusions and other analyzes and then restarted the test under the control of experts including Mr. Rasan, and certificate of Citroën France since the manufacturer of this additive does not want to recognize his wrongs ... especially with a client as "special" as a technical journalist!

Let's hope at least that it was quite mischievous to withdraw from its recipe, not miraculous but certainly very lucrative, the famous chlorinated paraffins banned from car oils for more than half a century! I'm sure he will ... but the damning analyzes are already done ...



Of course, these analyzes and other authoritative opinions of this English expert, one of the few in this little-known area where sharks exploit ignorance, remain valid for other additives, cleaners and other miracle solutions to simply include in your oils. 'origin. On this subject, if and only if you use an oil according to that recommended by the manufacturer with correct mechanical maintenance, no additives in the world can do better !

It's obvious that some people still want to ignore them. Indeed, an oil contains between 300 and 900 different molecules in precarious equilibrium valid one or two years at most. If you add so-called "miracle" additives, you will unbalance the chemical formula. The oil then degrades very quickly and loses all its qualities well before the normal emptying interval. Sorry for the mechanical poets, gullible and other fundamentalists optimizations but there are no miracles in mechanics or conspiracy of bad oil at these levels !

It is undoubtedly a pity, certainly, but it is only the truth. The hope remains but on such a level that only the majors have the qualified personnel and the means of Research and Development adequate to go even further.

In conclusion, do not expect to do better than the long-time specialist who designed your oil with additives sold in the local business or even by correspondence!



Mixture of different oils?

Once again, JR assures us that modern engine oil mixtures are safe except for the ... beaver oil still used in competition for its very special qualities. The risks of chemical interaction are almost nil but still possible so officially, to avoid bad publicity, manufacturers protect themselves by discouraging blends.

What is certain is that your mixture will take qualities close to the least efficient of the oils. To finish on an optimistic note, let's go to the test of the Titan GT1 which will bring a modest (to measure!) But real more without compromising your precious and expensive mechanics.

Titan GT 1 Oil Test

Here we find the 206 1,6 90 9.2 CV Julien, delighted to be my guinea pig for a day. It can be understood because during a previous test with a Green Direct Intake Kit, it already gained 10 CV DIN, + 0.9% in power, and 6 m.kg or + XNUMX%, which is excellent and confirmed our fears about the poor engine performance of the original "European homologation approved" intake system.

By analyzing a little the power curves, the gain is increasing from low to high revs and side torque we are even entitled to a very good + 1.5 m.kg to 2000 rpm, + 13%! Knowing that its MA5 gearbox supports 15 m.kg maximum, no worries. Other Rotronics bench data, acceleration times from 2000 to 6250 rpm on the final report, foot to floor: Small 1.6 improves 8.026 examination seconds to 7.457 is a better of 8%. Logically, this average gain in percentage must be on the road and the usual driver has noticed immediately, significant gains, especially the takeoff in 1ère much more frank 2000 rpm where the torque increase reaches its 13% with a load noise finally virile!

Note that these high-performance Green filters are also available for 4 × 4, motorcycles and even classic vehicles! And it's French manufacture!

Appointment was then taken over at Chazel technology in Montpellier, well known in the world auto competition or Renaud, the boss, we are as curious as interested in the results on his power bench Rotronics before and after emptying ... Fuch surely a new potential customer!

In this February 16 2006, the temperature is raised to 16 ° c instead of the 10 ° c of the previous "shot" to validate the direct admission Green. Despite the DIN correction and the Rotronics bench integrated weather station, with the same SP 98 petrol, the 206 displays "more" than 103,5 ch. at 5680 rpm and 14.02 m.kg at 4841 rpm. Like what, I'm right to do all these tests as soon as possible the same day to overcome the weather variations.

These first results are achieved with one of the oils recommended by Peugeot, namely an Esso Ultra 10W40 "base synthesis".

Drain, change of oil filter and three liters of Fuchs Titan GT1 on 3.2 liters max. The operation is led by a trainee BTS Mava. Return of the boss for the bench. I'm serene because this motorcycle oil, the Pro R 0W20 evoked above, has already proven itself every time. The operator places the 206 guinea pig in 3ème and accelerates thoroughly at M.Chazel's signal to the control PC. A loud throaty sound is heard before giving way to those of the engine and rollers. At M. Chazel's second signal, the operator disengages and the losses of the transmission until the clutch are calculated to obtain a power "engine". Positive verdict at the plot of the curve in real time and the exact figures then fall: 107.1 ch to 5872 rpm and 14.33 m.kg to 3327 rpm, this time. That is a gain of 3.4% in maximum power and 2.2% in maximum torque. The curves obtained with the Titan GT1 are always above the old ones except towards 5000 rpm or they are very close. Note also, the acceleration gain following the torque increase with a time that goes down from 5.865 second to 5.735, is 2.2% better. Figures "credible" by specialists and perfectly announced by Fuchs.

Added to the direct admission kit, the average autonomy of this 206 is passed from 500 to 600 km, which is + 20%
In other words, average road consumption has dropped by 20% ! So who says better and ... without mechanical risks, of course?

In conclusion: be attentive!

Once again, the best is the enemy of good. So in doubt, refrain from adding miracle additives to your oils on more and more sophisticated machines sensitive to product qualityI would have warned you!

In case of breakage or damage, do not hesitate to contact an expert, a voucher, and a consumer defense service, like the UFC and even, with a little luck, if you regroup within a Association, Stop Scams.

"Respect your mechanics and your mechanics will respect you!"

Close-up on the labels of a 1 liter 0W20 bottle: In addition to a very special smell, this golden and very fluid oil keeps its promises!


On the right, M. Chazel orders the passage to the buried Rotronics Autoscan power bench to measure cars as low as Renault formulas, for example. This custom bench available for your personal measurements, is able to measure 600 cv to over 300 km / h with a cooling wind of 70 km / h ...



Click to enlarge. As you can see, the Titan GT1 keeps its promises with torque and power gains everywhere! It remains to verify the decline in consumption that already exists, logically. Indeed, the owner confirmed me an average autonomy of 600 km instead of the 500 km with 2 cumulative improvements of the oil and direct admission kit with Green air filter. 20% of gain!
