Practical mileage guidance and tools

Get more kilometres per litre.

Start with the choices you make before and during a drive: plan the route, protect momentum and keep the car in good working order. Then use the calculators to plan a trip, compare fuel prices and measure your car's real mileage. Calculations stay on the page, and your optional mileage journal stays in this browser. Nothing is uploaded.

E20 mileage controls

Get more kilometres from every E20 litre.

An E20-ready car is engineered for the approved fuel. Preserve its designed efficiency through maintenance, route planning and calm driving. Your selected car's tyre-pressure panel stays specific to its sourced fitment and load condition.

Start before the next fillServiceTrafficThree-fill trend
01Maintenance

Protect efficiency

Protect the car’s designed efficiency

Keep the correct oil, air filter, spark plugs and service schedule. Use the fuel grade and consumables specified by the manufacturer.

Why this helps

An E20-ready engine relies on its original calibration and healthy sensors, ignition and air path. Regular maintenance preserves that designed condition.

02Route

Before every drive

Plan around traffic before you leave

Choose the clearer route and a sensible departure time. Use the efficient-route option when your navigation app offers one.

Why this helps

Fewer stop-start cycles mean less energy is repeatedly spent building speed and then discarded through braking.

03Driving

Every kilometre

Accelerate smoothly and brake early

Build speed progressively, look well ahead and ease off early when you need to slow down. Preserve momentum whenever traffic and safety allow.

Why this helps

Hard acceleration raises short-term fuel demand. Late braking throws away the energy already used to move the car.

04Driving

Engine control

Choose the right gear and revs

Move up through the gears smoothly without labouring the engine. In an automatic, use the normal drive mode unless the road or load calls for something else.

Why this helps

The aim is calm progress in the engine’s useful operating range, without high revs or asking a high gear to pull too hard.

05Cruising

Open-road control

Keep a steady, legal speed

Avoid repeated speed changes. On a suitable open, level road, cruise control can help; stay alert and use it only when conditions are right.

Why this helps

A steady road speed asks for fewer acceleration events. On hills or crowded roads, attentive manual control may be more suitable than cruise control.

06Journey

Cut wasted fuel

Combine short trips and avoid long idling

Group nearby errands when practical. Set off gently after starting, and switch off during a longer wait when it is safe to do so.

Why this helps

Repeated cold journeys use more fuel while the engine reaches normal operation. Idling consumes fuel while covering no distance.

07Load

Long-trip gain

Remove unused weight and roof racks

Clear out heavy items you do not need. Remove a roof rack or carrier when it is not in use, especially before a longer road journey.

Why this helps

Extra mass requires more energy during acceleration. A roof rack also adds aerodynamic drag as speed rises.

08Measure

Know your result

Measure your own result

Compare at least three full-tank intervals on broadly similar journeys. Note traffic, load, tyre check and service state with each result.

Why this helps

A single dashboard or tank result is noisy. A short, consistent record reveals the real range your car delivers and which changes are helping.

Mileage target

Turn the mileage controls into a number you can see.

Set a practical improvement target, see the monthly fuel and money difference, then take the plan into your next three complete tanks.

What is already under control?

My mileage journal

Turn every full tank into a useful trend.

Add the odometer and litres at each full-tank fill. FuelSaathi calculates the interval, builds a three-fill picture and keeps the journal only in this browser.

No car selected. This journal stays separate until you choose one.

The first fill establishes the odometer baseline. Your next full-tank fill creates the first measured interval.

Owner deadlines

Put the important car dates on your calendar.

Copy each date from the document or service record you already trust. FuelSaathi shows what is due and creates a calendar file, no account, upload or notification permission required.

Planning in this browser. Select a car to keep a separate plan for each vehicle.

Saved only in this browser. FuelSaathi does not upload, infer or verify the dates you enter. Calendar downloads include an alert seven days before each date; your calendar app controls whether it displays that alert. If you change a date, import the new file so supporting calendar apps can update the same reminder.

    Buy only what is needed to reach the destination reserve.

The plan assumes the entered mileage throughout, no detours and access to each listed outlet. Preserve a larger reserve for mountains, congestion, closures or uncertain outlet availability.

Use a reliable input

A precise calculator still needs a current price.

Use the price displayed at the outlet or your oil company's current retail price before relying on a saving. Prices can vary by outlet, so check the exact stop you plan to use. Route conditions, traffic, load, tyres and driving style can move actual fuel use away from the estimate.
