- the lubricant compositions used according to the invention have improved friction properties compared with lubricating compositions comprising either at least one molybdenum derivative alone or a boron derivative alone. These properties persist over time, even after aging.
- lubricant compositions used according to the invention offer improved performance to maintain a significant gain in fuel consumption over time, even after aging.
- the lubricant composition used according to the invention passes the sequence VI D successfully and therefore has good fuel efficiency. These performances persist over time, even after aging.
- the lubricating compositions are prepared by mixing the compounds described in Table 5. The percentages indicated correspond to percentages by weight relative to the total mass of the composition.
- Antioxidants (antioxidant combination
- Example 1 The Plint SRV test of Example 1 is applied to the new lubricating compositions as well as lubricating compositions aged under the same conditions as those described in Example 1. The results for new and aged oils are shown in Tables 6 and 7 respectively.
