Tonight I changed the ATF in my transmission. I had 5.5L of the Revenol JF506 oil left over from the last car I changed oil on. Unfortunately it's not available right now, so instead I made up the difference with Valvoline Import Multi vehicle ATF.

When pouring the oil into the transmission the Ravenol is noticeably thinner and less viscous than the Valvoline. The Valvoline sheet shows a cold viscosity of 36.3 cSt, which is a similar viscosity to Dexron III, so I suspect the original JF506 oil is a low viscosity oil. Unfortunately, technical data is scarce on the Ravenol, so I have no idea what the claimed viscosity is. It did drain through my funnel faster than the Valvoline though.

If I can't get the Ravenol in the future, I'd probably be looking for the Fuchs Titan 3353, or something meeting Mercedes 236.12 spec. The Fuchs meets the Ford spec our transmissions call for.
