Owners and shoppers of the 2013 BMW 335i often want a clear picture of how many miles they can get from a tank of premium fuel. This mid size luxury coupe balances spirited performance with everyday usability, and its fuel efficiency plays a big role in ownership costs.
Because this car relies on a turbocharged inline six, the real world gas mileage can shift with driving style, climate control use, and fuel grade. The following sections break down what you can expect from the 2013 335i and how it compares to similar sport sedans.
| Metric | Value | Notes | Source |
|---|---|---|---|
| Fuel Type | Premium Recommended | Higher octane helps control knock from the turbo | BMW Spec |
| City MPG | 20 MPG | EPA combined driving estimate | EPA |
| Highway MPG | 30 MPG | EPA steady speed estimate | EPA |
| Combined MPG | 23 MPG | Weighted blend of city and highway | EPA |
| Tank Capacity | 15.9 Gallons | Usable fuel for range calculation | BMW Spec |
EPA Ratings For The 2013 BMW 335i
The official EPA numbers provide a baseline for how far the 2013 335i can stretch each gallon. These figures assume premium fuel and standardized testing cycles, so your mileage may vary in daily driving.
With a 15.9 gallon tank, the combined 23 MPG estimate translates to roughly 360 miles of total range under mixed conditions. The highway number of 30 MPG is a strong point for this class, while the 20 MPG city figure reflects stop and go traffic and accessory usage.
When you account for air conditioning, cold weather, or aggressive acceleration, real world results can dip noticeably. Planning around these variables helps you maintain confidence in your daily range and fuel stop timing.
Driving Style And Real World Mileage
How Performance Habits Influence Fuel Use
Because the 335i was tuned for responsive throttle and firm shifts, enthusiastic driving can quickly cut into gas mileage. Hard accelerations and high speed cruising push the turbo and engine load, raising fuel consumption.
Smooth throttle inputs, gradual braking, and using Eco Pro modes when available can noticeably improve your real world numbers. Many owners find that relaxing the pace while still enjoying the chassis balance keeps the experience engaging while saving fuel.
Highway Versus City Usage Patterns
On the highway, steady speeds and lower rolling resistance help the 335i reach its best MPG numbers. In city traffic, frequent stops, idling, and accessory loads reduce efficiency, even with start stop systems at work.
Understanding your typical route mix lets you estimate monthly fuel costs more accurately and adjust driving habits where possible without compromising the driving experience.
Maintenance And Technology Impact
Engine Tune Up And Tire Pressure Factors
Keeping up with scheduled maintenance, including spark plugs, air filter, and fuel injection service, preserves optimal combustion efficiency. Underinflated tires create more rolling resistance and can lower gas mileage by several percent.
Using the correct oil viscosity and fresh oxygen sensors also supports efficient turbo operation. Simple habits like removing excess roof load and limiting aggressive accessory use add up over time.
Cold Weather And Accessory Effects
Cold temperatures thicken engine oil and can reduce battery efficiency, which may temporarily lower MPG during winter months. The use of heated seats and defrosters also draws extra power, slightly increasing fuel consumption.
Planning warm garage parking when possible and moderating climate demands during peak heat or cold stretches can help you get closer to the EPA estimates rather than below them.
Comparison With Similar Luxury Sport Sedans
Placing the 2013 BMW 335i beside rivals from Mercedes C Class and Audi A4 highlights how its efficiency stacks up against performance claims. While outputs differ, most engines in this segment trade off power for economy in comparable ways.
Looking at combined MPG and tank range helps you gauge which car aligns with your performance expectations and refueling convenience. The table below summarizes how the 335i fits within its competitive set.
| Model | Combined MPG | City MPG | Highway MPG | Notes |
|---|---|---|---|---|
| 2013 BMW 335i | 23 MPG | 20 MPG | 30 MPG | Inline 6 turbo, premium fuel |
| 2013 Mercedes C350 | 22 MPG | 19 MPG | 29 MPG | V6 turbo, premium fuel |
| 2013 Audi A4 3.0T | 24 MPG | 20 MPG | 31 MPG | I4 turbo, premium fuel |
| 2013 Lexus IS 350 | 21 MPG | 18 MPG | 28 MPG | V6 naturally aspirated |
Fueling And Long Term Ownership Costs
Premium fuel requirements mean the 2013 335i typically costs more at the pump than similar cars designed for regular gas. This difference can add up over years of ownership and should factor into your total cost calculations.
Insurance, depreciation, and maintenance also play major roles in ownership expenses. Evaluating how MPG, range, and fuel prices interact helps you estimate realistic annual budgets.

FAQ
Reader questions
Will the 2013 BMW 335i get worse gas mileage if I use premium fuel incorrectly?
Using premium fuel is recommended because it supports the engine’s compression and knock control. Failing to use premium can cause the engine computer to retard timing, lowering performance and potentially reducing efficiency under load.
How much does aggressive driving lower the MPG of a 2013 335i?
Hard accelerations and high speed passes can noticeably cut combined MPG, sometimes by several points versus a smoother approach. The turbocharged six cylinder responds strongly to throttle inputs, so relaxed driving preserves both fuel and drivability.
Does using the air conditioner significantly hurt highway MPG for this car?
On the highway, air conditioning can reduce 335i MPG by a few miles per gallon at most. The engine’s power reserve helps absorb this load, but in very hot weather, fuel economy will decline.
Can cold weather drastically lower city MPG for the 2013 335i?
Cold weather and short trips can lower city MPG because the engine takes longer to reach optimal temperature and accessories like heating increase electrical demand. Planning fewer cold starts helps preserve winter efficiency.
