Slight smoking issue, blue smoke, used a combo of Valvoline High Mileage 10w40 and Lubro Moly to fix this. Since then, no more smoke, and not losing any or burning any oil.
Transmission started to drip very slightly; did a flush, changed the filter and added a combination of Amsoil, Valvoline High Mileage and Lucas Trans Fix.
The car has a lot of power and torque!
All the room of a big American car, and all of the power and handling of a German car.
This car is rock solid. I want to share some advice for those of you who purchase any of the W126 cars.
If the car is smoking, "blue smoke", use Liqui or Lubro Moly!
Oil, Rotella T6 5w40 synthetic, Amsoil, Liqui Moly, Valvoline High Mileage 10w40.
Coolant, aftermarket "Zerex G-05" approved by Mercedes! About half the cost of the dealer stuff.
Differential oil, Mobil One 75w90.
Transmission oil, Amsoil ATF, Valvoline High Mileage.
I would have given this car higher performance marks, however I test drove a 1999 S500. Amazing!
Would you buy another car from this manufacturer? Yes
