1992 Import Trade Services MB 300SL: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 1992 Import Trade Services MB 300SL. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain.

Fuel economy at a glance

These are the EPA's official ratings for the 1992 Import Trade Services MB 300SL. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 1992 Import Trade Services MB 300SL compares

The 1992 Import Trade Services MB 300SL returns 17 combined MPG. Cars in the Two Seaters class for the same model year average 16.7 MPG, which puts this car ahead of the class average by about 2%.

The most efficient car in the Two Seaters class for the 1992 model year is the Geo Metro LSI Convertible at 30 MPG. The bar chart below puts the Import Trade Services MB 300SL alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 1992 model year (across all classes) returns 18.5 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 1992 model year is on its own page.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for regular gasoline, which is $3.99/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 882.4 gallons (the car's annual consumption at the rated MPG).

Specifications

The 1992 Import Trade Services MB 300SL runs a 2.9-liter 6-cylinder engine paired with a manual 5-spd, sending power through rear-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.

• How much does it cost to fuel a 1992 Import Trade Services MB 300SL per year?

  The EPA estimates an annual fuel cost of $3,500 for the 1992 Import Trade Services MB 300SL. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade.
• What fuel does the 1992 Import Trade Services MB 300SL use?

  The EPA lists the 1992 Import Trade Services MB 300SL as running on regular gasoline. Using a different grade than the manufacturer specifies can affect fuel economy and engine longevity.
• How much CO₂ does the 1992 Import Trade Services MB 300SL emit?

  Tailpipe CO₂ emissions are 523 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 7,841 kilograms of CO₂.
• What is the difference between the city and highway MPG of the 1992 Import Trade Services MB 300SL?

  City driving returns 15 MPG and highway driving returns 21 MPG, a gap of 6 MPG. A spread that wide is typical of cars with conventional automatic or manual transmissions, where stop-start city traffic eats more fuel than a steady highway cruise.
• What engine is in the 1992 Import Trade Services MB 300SL?

  The 1992 Import Trade Services MB 300SL has a 2.9-liter 6-cylinder engine (EPA description: (GUZZLER) (FFS)).

  The 1992 Import Trade Services MB 300SL comes with a manual 5-spd transmission and rear-wheel drive.
• How does the 1992 Import Trade Services MB 300SL compare to the best car in its class?

  The most efficient car in the Two Seaters class for the 1992 model year is the Geo Metro LSI Convertible at 30 combined MPG. The Import Trade Services MB 300SL returns 17 MPG, a gap of 13 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
• Does the 1992 Import Trade Services MB 300SL qualify for the gas guzzler tax?

  Yes. The federal Gas Guzzler Tax applies to passenger cars rated below 22.5 combined MPG, and the 1992 Import Trade Services MB 300SL falls below that threshold. The tax is paid by the manufacturer at the point of sale and is built into the sticker price, so you will not see a separate line item at the dealership. Pickup trucks and SUVs are exempt from this tax even when their efficiency is lower.
