Transmission Fluid




Suppose Shell 134 is good, but than how much you can save on buying substitutes?








When MB does allow substitutes, they are still substitutes.
The differences can be subtle, but for years I am observing that each time MB owner comes to a forum with overheating problem - he is using Zerex substitute not MB coolant.
Something that we can't measure right away, but I am using MB coolants even in my Ford Trucks as they cool the engine with no need for fans.
Also I drove E300DT for 4 years with engine fan removed, hitting 114F on deserts without overheating.
Something people like Plutoe will never understand.
