  2. 50wt engine oil
    Yes it is the same...close enough anyway. SAE 90 gear oil is equivalent to 50wt engine oil (SAE 80 = 30wt), so you could always dump that in instead if you want. 15W40 diesel oil is close enough to dump in there.

    Which gear oil is equivalent to SAE 90 gear oil?
    It’s North American equivalent is AGMA 5 R&O gear oil, or AGMA 5EP Extreme Pressure gear oil. Most modern SAE 90 gear industrial oil misses the KV@40 o C by a small margin, but it is close enough; you need it equivalent to SAE 110 gear oil, which is not available in almost all markets.

    Is SAE 90 gear oil thicker than SAE 40 or 50?
    While many motorists may assume SAE 90 gear oil is thicker than SAE 40 or 50 engine oil, their viscosities are the same, as this gear oil viscosity chart shows. One major difference between the two are in the additives they use. Motor oil contains additives such as detergents and dispersants to combat byproducts from gasoline or diesel ignition.

    Is 75W90 gear oil better than SAE 90?
    Thermal stability is a key factor to consider, as it indicates the oil's ability to withstand high temperatures without breaking down. 75w90 gear oil generally offers better thermal stability compared to SAE 90 gear oil due to its synthetic blend and additives that enhance heat resistance.

    Which sae90 oil was recommended?
    Can you find out which sae90 oil was recommended exactly? sae 90 has been split into sae90 and sae110 in recent years, so if they recommended a thick sae90 you could consider sae110 and be in spec. I used to have a Wheelhorse and used a synthetic 75W110, a good wide temperature gear lube. This would be my choice…

      UNDERSTANDING THE DIFFERENCES IN GEAR OIL SPECS

      There are differences in the additive technology used for lubricants for each specification, and just because one type of gear oil works well for one type of gear application, that doesn’t mean it will work well for all.
