<p>The invention concerns an alkaline reagent for use in stabilising motor oil and consisting of a tin-bearing component and a metal hydroxide. A novel feature is the fact that tin ore refinement products are used as the tin-bearing component, and the metal hydroxide used is a hydroxide of an alkaline earth metal and/or the hydroxide of an alkali metal, the respective proportions being as follows: tin ore refinement products (calculated for SnO2) 3-90 wt.%; metal hydroxide 10-97 wt.%.</p> |
