How much oil can you fit into a 380SL? :confused:

Sure the manual says the capacity is 8.5 qts with filter...but...

Somehow the bonehead I bought my project 380SL from managed to squeeze 14-1/2 quarts in. Probably closer to 16 when you include the oil that soaked my garage floor as i tried in vain to get the plug back in as my 10 qt recycling container filled at an amazingly brisk pace! Did he forget to drain the old oil before adding new at the last change...who knows. At least I now know why it belched oil out the breather when it ran for 2 minutes!

Maybe you have the wrong dipstick.
Or maybe the PO was a dipstick.

Four of your containers are no problem. One of them could lead to a dangerous accident.

If that container came with the car it could explain the overfilling. :D

It never ceases to amaze me that somoeone would do something like overfilling that much, not to mention that it would even fit. :eek:

380 dipstick length

Looks like you purchased the SL Valdez..:)

Overfilling can cause alot of problems, good you caught it now, Here's a few pics of my dipstick. Make sure you have the correct one installed. It's just amazing what some poeple will do. Good luck with your project, now I would question all the fluids, tranny and all......

It might smoke for a while when you get it started again, I have to believe it was blowing past the rings when it was running.

If the car was layed up for storage the PO may have filled it up as a percautionary measure. I have heard of filling the crankcase completly with kerosene before, but not oil.

I verified it has the right dipstick. I had noticed it was beyond the range when i looked at it, but didn't think it would be or could be that far above capacity.

The kerosene comment is interesting. This stuff was pretty runny for a car that had been sitting for a while, but the 20W-50 that I put in seemed more watery than I expected also. It had a bad odor, but i didn't think anything of it because of how long it was sitting.
