My car has Synchromesh – can I still use ZX1 Micro Oil Metal Treatment?
We understand your concern for the synchromesh, because of the way in which the rings work, however, it has been found that ZX1 benefits the gearbox and does not compromise the efficiency of the synchromesh. Our racing contacts have informed us that if you are an experienced racing driver used to many different gearboxes you might notice a few milliseconds delay in the gear change but in the last 10 years that has only been commented on by one very experienced racer who said he would rather protect his gearboxes with ZX1 as the very slight delay did not compromise his performance on the track and since using ZX1 has never suffered a transmission failure whereas, previously it was one of his major mechanical failures in endurance races.
