So I bought some OEM Yanmar gear oil to change out the final drive lube.
They specify GL4 and I usually use Valvoline GL4-GL5 oil but since it was not
expensive I bought the OEM stuff.
Had I known that using this magical oil in my excavators travel motors would also keep my engine running smooth,clean, quiet and with less emissions I would have never used that Valvoline garbage.
