Differential Fluid
Hi guys,
In my 1990 300e, I run Mobil 1 engine oil and Mobil 1 trans fluid, both with good results. In the differential I currently run the recommended weight (forget what it is at the moment) hypoid gear oil. Anyone using synthetic in their differential? And, if so, to what result? |

It's your choice, but the result is more profit for whoever you bought the synthetic oil, tranny fluid; gear oil from.
Absolute waste of money. Conventional lubricants have carried many of us hundred of thousands of miles.

I just changed mine to Royal Purple synthetic 75W90. Guess I like paying more.
I run synthetics whenever I can. Chris

With all due respect to another's viewpoint, I prefer the chemical strength and longevity of synthetic lubricants. Especially in today's hotter running powerplants. I suppose it is debatable for differentials and transfer boxes. However, considering these get changed on a far less frequent basis, as compared to engine oil, cost per mile is not that much different and I get a more robust lubricant.

Here's another way of looking at it... OEM is going to synthetic diff fluids, I believe for CAFE requirements. Apparently the premium cost for 1-2 qts synthetic diff fluid is offset by the small increase in gas mileage.

in my W124 (87 260E). I was told by the mechanic that the noise from the back when I drive is from the differential which he says has been quite worn out. However he says you can still drive it for years without any problems. However the noise bother me sometimes. I wonder if I switch over to something synthetic it would reduce it. If it does the I think its worth teh money. |
