WOW ,,, back then i remember so many Mercedes owners coming into my engine shop complaining about the noise just as a second opinion i always said that is the way they were and they were great.. much much better than the mercedes engines now... Back then i could count on my one hand how many MB engines we did and we are a busy engine shop today we always have at least 1 in my shop its nuts they were great engines then.
 
My Tribute, that calls for 5W-20, ran pretty darn good and smooth on Pennzoil Conventional 10w30 and a Fram PH2.

Might use it again this summer....
 
I run the Pennzoil High Mileage 10w30 in my Ranger and my engine has never been more quiet. Im sticking to it.
 
May have been a matter of what they were coming from.
A lot of traditional American car buyers bought MB diesels in the late seventies and early eighties.
This was a time when even higher end buyers were concerned about fuel economy, and a diesel Benz gave you both better fuel economy and more snob appeal than any higher end American car.
Besides, only pimps drove Eldos or Mk Vs.
The diesel Benz did have diesel clatter, especially at idle and was never a silent car, as a Caddy or a Lincoln, or even a Caprice typically was.
The Mercedes also had a hard mechanical note to it, unlike any traditional American large car of the era.
I always though our Benz diesels sounded good, but I had a different frame of reference from many who bought them.
I'd not be surprised if many buyers assumed that there was something wrong simply due to the lack of power.
Even the 300D Turbodiesel in the 123 was not really energetic and was even less so in the short wheelbase S-class in which it was also offered.
This was a time period when 80% of Mercedes' US sales were diesels.

I always wanted to try that oil - never had the courage though.

Its great stuff. Ran perfectly in my 3800 series ii and helped stop the leaks it had. I ran it in very hot temps with many hours of stop and go (car cruises) and aggressive driving as well. I'd happily run it again.
 
Due to a huge score of almost free oils, I had lots of Pennzoil Conventional 10w30 and some Pennzoil conventional SAE 30wt. In warm/hot south TX, I mixed the two with great success. Buttery smoothness and outstanding quietness.
 
Pennzoil High Mileage is great stuff i use it only in the summer because its pretty thick but it works great.. Its getting pricey if the price goes up any more i wont be using it.
