Not normal, but within specifications. Generally, the harder an engine
is driven the more oil it will use. I've owned a 300SD for many years
and find it uses about 1 to 1.5 qts in 5K miles; its now at 108K. A well
maintained diesel should go 250K to 300K miles, much less if poorly
The best diagnosis of any diesel's condition is a compression check.
That WILL tell you whether that engine is in good condition (and has
substantial miles remaining before an overhaul is needed) or will be a
bad buy. Either way, YOU will know and then can buy or walk away with
confidence in your decision.
I'm afraid I don't know how much an MB 5 cyl uses or is spec'd to use.
I'm guessing that it's a fairly recent car. I also don't know what a
quart is :-)
I took my '98 300TD back to the dealer when it was less than six months
old because it was using about a litre every 10,000 miles. They said
that was perfectly within tolerance.
I'm sure if you call a dealer, they'll give you the expected oil usage.
I have an 83 300SD, engine is in perfect condition with 180,000 miles.
I have had this car from 65,000 miles and it uses about a quart of oil
every 2,000 miles in mixed driving. Highway speeds normally at 75-80
mph, city 35-45 mph. The engine actually runs betyter now than it did
when I first bought it. A quart in 1,300 miles sounds a bit excessive,
do a compression check. Take the oil cap off with the engine running,
if you have lots of blowby it will show up there. IMHO, at a hot idle,
the oil pressure gauge should read no lower than 1.5 bar. Good Luck,

Don't forget, some of this oil could be leaking also... Which is
usually a better deal since it's often easier to fix leaks that are
Take a good close look around the engine compartment/undercarriage and
you might see somewhere that some of the oil is escaping...
That's too high. I've owned two W123 300*Ds that were purchased
with over 150K miles on them and which both went over 200K. My
oil change inteval was 4K miles, and neither of them ever needed
any oil added between changes. The oil level in the first car
never decreased visibly at all, and the oil level in the second
car, which I still have and which now has 270K miles on it, just
barely drops between oil changes.
'91 300D 2.5 60K
'82 300CD 279K
'85 300D (RIP)
