<p>EP lubes are formulated with an anti-friction additive especially for use in hypoid gear sets. That is because hypoid gears use a sliding contact rather than a rolling contact and the EP additive is required eliminate friction and to allow them to survive
in use.</p>
<p><br>
</p>
<p>EP lubes should not be used in mechanisms that require built in friction to operate properly such as synchronizer rings in transmissions or limited slip differentials.</p>
<p><br>
</p>
<p>Detergents in oils are intended to suspend microscopic contaminants such as soot particles in engine oil so it doesn't settle out and form deposits in oil passages. I will not suspend large particles such as brass or iron filings.</p>

<div class="moz-cite-prefix">If there are bronze/brass baulk/synchro rings in the gearbox it is best to be on the safe side and not use EP oils that contain halogens F, Cl, Br, I as these may attack the bronze/brass components. Sunbeam for that matter stipulated
to use SEA 30 or 20W50 engine oil. I do not see a reason to take the risk using EP oils. They do not ad much if anything. Straight or detergent containing does not matter much if you change the oil on a regular basis as prescribed in those days. Oil is cheap
so I change the oil in my gearbox every time I change the engine oil, i.e. once a year. Use a drain plug with a magnet.<br>
<br>
Modern gearboxes may not even have a drain plug as the oil is never changed and we have become used to that!<br>

non-detergent oil allows any wear particles to settle out of the oil instead of being continuously circulated through the mechanicals.</span></p>
