Hi!
We Ravenol there is one serious enough problem. Features fresh oils vary greatly from batch to batch. It all started after the winter testing amateur Ravenol VSI 5W-40, in which the oil is from the same batch had a good flow, and the other was more of a murky and there was less fluid. Then there were the tests Ravenol HCl 5W30, here's the first test of this oil: Ravenol HCL first test . Judging by the VOA - excellent oil. With the stock satisfies the Mercedes-benz 229.5, also in the possible presence of esters.However, not so long ago has been tested oil from the other party, after the change of packaging, the results here: Ravenol HCL second test . And here is the real problem is visible. The fact that requires 229.5 TBN > 8 (or 9 forgotten something I) whereas active HCL showed significantly lower value and is not entered in tolerance requirements. However, on the packaging of the oil is still written 229.5. This is the second time for a short time when oil Ravenol show completely different characteristics of oils with the same tolerances.

We tested the oil by other manufacturers (such as Mobil1), characteristics of oils from different parties were very close (at the level of measurement error.)

Sorry for my English, I use google translate.
Best regards

Yes, indeed, it is impossible to create exactly the same oil in different parties, however, among the VOA tests that we carried out on the forum, only ravenol kolosalnye showed such differences from the party of the party. And, in the second test HCL, oil banal fit into the requirements of admission. We've found some oils that do not fit into the CSS (some) by SAE J300, however Ravenol so far the only company that has not very stable characteristics, and not written in the manufacturer's tolerance.
A little later I'll look for the results of tests of Mobil from different parties, for comparison. There is minimal dispersion characteristics.
