Di figa manco a parlarne ma va bene così 

dopo una simile dichiarazione di amore da Emi....io starei accuort..

Coioni....

Se qualcuno ha voglia di leggere, qui c'è un test comparativo dell'impatto di 8 diversi prodotti sugli o-ring.

Parte 1:
(immersione nelle diverse sostanze per 24hh)
https://advrider.com/f/threads/chain-o-ring-wd-40-exposure-effects-study-and-results.345397/
Conclusioni:

Conclusion of short term exposure:
1. Carb cleaner and Gasoline samples swelled to significant sizes. Definitely not recommended to use these fluids to clean an O-ring type chain. The carb cleaner exposed O-ring increased in diameter by 29%! The gasoline exposed O-ring increased in diameter by 11%.
2. WD-40, and Kerosene seem to have negligible to no effect on the O-rings (+/-1%)
3. Brake fluid, and PJ1 chain lube seem to have a negligible to small effect on the O-ring's size.


Parte 2:
(immersione per 15gg)
https://advrider.com/f/threads/part-ii-wd-40-o-ring-exposure-effect-results.350310/
Conclusioni:

Final results for all soaked O-rings
Results of study:
All the chemical had an effect on the strength levels. Based on the reduction in strength after 15 day continuous exposure, it appears WD-40 reduced and had a detrimental effect on the the strength of the O-ring (20% reduction after 15x days). Whereas, the Kerosene reduced the strength level by 12%. More rigorous investigation is required, however based on these results I'll be using Kerosene to clean my X ring chain.

In sostanza... il cherosene, o petrolio bianco che dir si voglia, non produce nessun particolare effetto negativo sugli OR.
