Synchromax is recommended for manual transmissions that require automatic transmission fluid. Synchromax is formulated with Royal Purple's synthetic, proprietary Synerlec additive technology, which offers improved shift quality over a wide temperature range and reduced gear noise.
Synchromax is fully compatible with all types of friction materials and offers excellent corrosion and oxidation protection without affecting the soft metals commonly found in manual transmission synchronizers.
Synerlec Additive Technology-Beyond Synthetic
Synthetic oils enable Royal Purple to make superior lubricants, but it is Royal Purple's advanced Synerlec additive technology that gives its lubricants their performance advantages. Synerlec additive technology truly is Beyond Synthetic.
Synerlec additive technology forms a tough, slippery, synthetic film on all metal surfaces.
