1957 Mercedes-Benz 300SL Engine Test

After final assembly of the 300SL engine, it is time to bench test. No only is this fun, but it checks for oil leaks, oil pressure, engine temp, timing, etc. The final run-up was only to about 3000 RPM since there was no load on the engine.

Do you think there was a British of Italian equivelant in the same era as the 300sl?

@neilious01

D-type and XKSS Jaguar and various versions of the 250 series Ferrari.

I have got a very good hint for you to keeping the nice old 300 Engine in good shape with todays ultra dry eco fuels: Use 1:100 API TC two stroke oil / fuel mix as regular driving fuel, that keeps the old fuel-system gaskets, rubber parts, alloy parts etc... and cast iron metal surfaces of those vintage engines in excellent shape...and it also lubricates the valves and upper piston regions. Most Porsche vintage owners in Germany do so :) Also keeps carbs and tank clean and rustfree

@Ruelpsgruetze

Thank you for the suggestion. Our fuels are terrible and getting worse. You suggestion is great.

Saw my first one in Germany the year it came out. It was a red one. Top was down and the driver was a nice looking blonde lady. I've always remembered the car and, as I was only then 23, the blonde too !!!

@wfs52 Runs a bit low doesnt it?

[2URBO2]

@Ruelpsgruetze God idea!

But as for the carbs, as you may or may not know, doesnt matter, the 300SL engine has DIRECT fuel injection mechanicly. :) Mercedes was the first who did this, it is geniously. You can see the injectors at 0:17 and fuel lines back to the mechanic pump.

@wfs52 great vid BTW. I never knew the 300SL was direct injection. Lots of people don't like the engine note on these but I think it's really nice..

[dynaco]

@wfs52 I've read the identical comment on many other classic car vids (about using a particular 2-stroke fuel mix), so that user is just spamming you tube with advertising.

That is a beautiful sound out of that engine. I have only seen one Gullwing 300SL. It was in a parking structure, and that car did not look like attention was given to it like the museum piece that it is.

I really wish I could hear a car like this in person.

Putting a bit of oil into fuel is a very good idea, I did this a long time ago when breaking in rebuilt MB engines in the State. I remember German Gasoline in the sixties as wretched stuff, often lots of water and crud, clogging the fuel filters completely.

[neilious01]

@wfs52 I would think those cars were fairly temperamental compared to the 300, then again I could be wrong.

[scwarzewaffe85]

that sounds beutiful,like a ww2 plane engine when it was 1st started!
