 Re-Metallisers |
| |
| These types of additives essentially contain particles of copper, silver & antimonite (zinc & tin). |
| Unfortunately, these particles can not properly adhere to lubricated surfaces, which are subject to intense friction. |
| They may be able to locate in the crevices of score marks, but will not compensate for the overall wear & tear of the engine. |
| If such additives do show an apparent effect, this may not be caused solely by a re-metallising effect but by the fact that the added metal particles oxidise the oil, once it reaches temperature. |
| Such oxidisation translates into thickening of the oil and thus producing the same results as thickening agents. |
| Further, certain re-metallising particles create electrolytic effects with metals used in the engine (copper-alloys, aluminium). |
| As to lead, it is exactly what one wish to avoid,
particularly to protect environment. |
| Such products can show efficiency in old engines that smoke. They may, temporarily, prevent oil reaching the combustion chamber & reduce smoke emissions & render the vehicle more saleable. The new owner
will soon find the mask slipping & smoke emissions returning. |
