As a proud owner of a 1989 Mercedes-Benz 560SL, you’re not just driving a car—you’re maintaining a piece of automotive history. Whether you’re new to classic car care or a seasoned enthusiast, knowing exactly how much oil your 560SL needs—and how to change it properly—is essential for keeping your V8 engine running like it should.
Let’s explore oil capacity, the right oil to use, oil filter tips, common mistakes to avoid, and everything else you need to know.
How Much Oil Does a Mercedes 560SL (1989) Take?
. 1989 Mercedes 560SL, equipped with the 5.6-liter M117 V8 engine, requires:
| Oil Change Type | Oil Capacity (Quarts) |
|---|---|
| With Filter Replacement | 8.0 quarts (7.6 litre) |
| Without Filter Replacement | ~7.5 quarts (7.1 litre) |
Important Note:
Always check the oil level on the dipstick after refilling and running the engine for a minute or two. Top up as necessary, but don’t overfill—this can cause foaming and reduce lubrication efficiency.
What Type of Oil Should You Use in a 1989 560SL?
Your 1989 Mercedes-Benz 560SL was designed during an era before synthetic oil became the norm, but using modern oils is actually recommended for better protection—especially with today’s driving conditions and stop-start traffic.
Here’s a quick reference for oil types:
| Yağ tipi | When to Use |
|---|---|
| 10W-40 (Sentetik karışım) | Good for mild climates and classic engine protection |
| 15W-50 (Tam sentetik) | Best for high-temp driving or long-distance trips |
| 20W-50 (Geleneksel) | Close to factory recommendation for warm climates |
Uç: Always go with high-zinc content oil (ZDDP additive) to protect flat tappet cams in these older V8s.
How Often Should You Change the Oil?
Even if you’re not driving daily, oil degrades over time. Here’s what’s generally recommended for a classic like the 560SL:
-
Every 3,000 mil veya 6 aylar, hangisi önce gelirse.
-
If the car is in storage or only used occasionally, change the oil at least once a year to prevent sludge and moisture build-up.
Which Oil Filter Is Best for the 560SL?
Stick to OEM or high-quality aftermarket brands. A poor oil filter can cause pressure loss or let debris circulate.
Recommended Oil Filter Brands:
-
MANN (HU719/6x)
-
Bosch
-
Mahle
-
Hengst
Avoid no-name or ultra-cheap filters, as these often don’t meet the pressure or filtration standards for the M117 engine.
How to Check Oil Level in a Mercedes 560SL
-
Park on level ground and turn off the engine.
-
Wait 5–10 minutes to allow the oil to settle.
-
Remove the dipstick, wipe clean, and reinsert fully.
-
Pull it out and check the level—it should be between the two marks.
-
If it’s low, add oil gradually, about half a quart at a time, and re-check.
Common Mistakes to Avoid
-
Overfilling the oil – Leads to frothing and oil seal damage.
-
Using the wrong viscosity – Can cause poor lubrication and startup wear.
-
Skipping filter changes – Allows contaminants to recirculate.
-
Not warming up the car before checking oil – May lead to inaccurate readings.
