I was just looking through the factory service manual, and under the chassis and body section it list various specs. Under the Technical data section they list "Engine oil consumption" It says "ltr./100km(miles/US qt).....0.25(262)". This is for my 300SD. Now here are my questions pertaining to this data. One, do they mean pt instead of qt. Second, are they serious that the oil consumption of 1 whole pint or quart, per 262 miles is within tolerences? Even if the "qt" is a miss print and is supposed to be "pt". That still works out to 1 whole quart of oil every 524 miles. Tell me this can't be right. Going through that much oil, you would have a constant cloud of blue smoke as you drove. For those who have this manual it's on page 00-020/16 of the service manual, series 116, volume 1. In the same section they list data for the infamous 6.9. It says the oil consumption rate for that car is one pint per every "196-118 miles" I know the numbers are backwards but that's they way they're written in the manual.
Now maybe I am reading this data wrong but it sure does look like that's what they're stating as being normal oil consumption. I tried to look up what the oil consumption rate was for the other engines listed in the manual but "oil consumption" is not listed. Can anyone make sense of this data.
