Older series vehicles are fine with good quality oils and frequent changes. So do oil additives work? Usually yes but they’re only effective on cheap oils. If oil is even half decent, additive will probably upset the chemistry. Better just to buy good oil to start with. Water may have been pulled in to the axles cold water creates a partial vacuum in the warm axle, and water is pulled past the seals. Water trapped in your axle sinks below the oil loosen the drain plug and check for water or creamy oil.

    

Best avoided, because it can wash oil off the bores, allowing wear and it ends up in the sump, diluting your oil. Gun it at high speed down the motor way, turn straight into the service area and stop the engine. Your turbo runs a higher temperature than the engine itself, and it’ll sit there cocking. If it’s too hot, it’ll carbonize the oil which will block the turbo’s small oil ways. Instead, drive the last two or three miles steadily or let the engine tick over on arrival, so the turbo can lose temperature. Cheap oils are most likely to harm your turbo use a good quality semi or fully synthetic. Made with synthetic technology may mean simply that it’s semi synthetic
