German Moped Days Fuel and 2T Oil Guide
Fuel and two-stroke oil are separate tanks in German Moped Days. What each costs, when to fill them, and which pass removes the whole system.
German Moped Days runs on two tanks, not one. Fuel goes in the tank, two-stroke oil goes in its own reservoir, and the engine needs both. Empty either one and the moped stops, which is the single most common way a new player loses a session.
This page covers where both are bought, how the station prices them, what happens when you mix wrong, and whether the Endless Fuel pass is worth the Robux.

Two tanks, one engine
The official pitch is four lines: chill rides on classic German mopeds, kick-start, mix your fuel, cruise. The mixing is not decoration. A two-stroke engine has no separate oil sump, so lubrication arrives dissolved in the fuel, and the game models that as a second resource you buy and carry.
In practice the loop looks like this:
- Pull into a station.
- Buy fuel.
- Buy two-stroke oil.
- Leave with both tanks full.
Skipping step three is the classic mistake. The fuel gauge is the instrument you watch; the oil reservoir is the one that ends your ride, and it empties slower, which makes it easier to forget and worse when it does.
Where to buy and what it costs
Fuel and oil are sold at the station, at pumps with a price board. The official screenshot shows a display reading roughly 0.69 per litre, which is a themed number rather than a simulation of German pump prices, where a litre of E10 has been closer to 1.80 euros for years.
The game's own store confirms that fuel is a real cost with a real discount cycle. It sells a 30-minute 50% discount on oil and petrol, which means:
- Both are bought, not found.
- Both have a price the game can halve.
- A discount window is the cheapest time to fill up, especially if you plan a long job chain.
There is also a 15% discount on the whole store for one hour that appears as a temporary item. If it covers the station as well as the parts shop, that is the moment to top up. We could not confirm which shops the store-wide discount applies to, so treat it as a bonus rather than a plan.
The mixing ratio, in game and in real life
The real Simson S51 and Puch Maxi both run on a 1:50 mix, the standard for small two-stroke engines: 100 millilitres of two-stroke oil to five litres of fuel, or one part oil to fifty parts petrol. That is the number every German moped owner knows.
Whether the game asks you to mix manually, sells pre-mixed fuel, or simply drains two independent tanks is not documented. The description says "mix your fuel", the store sells oil separately, and the Endless Fuel pass says your mopeds "never run out of fuel or oil", which implies two consumable resources rather than one mixed product.
What that means for you:
- Treat oil as a tank, not a bottle. Buy it at the same stop as fuel.
- Do not assume a ratio input exists. If a mixing UI appears, the real-world 1:50 is the number to try; if it does not, the game is abstracting it.
- Watch the oil after a long session. Two-stroke oil is consumed slowly enough that players notice it only when it is gone.
In a real two-stroke, oil starvation seizes the engine. The game models the tanks and sells a pass to remove them, which suggests running dry is meant to be a real consequence. Carry oil before you need it.
When to refuel
The route logic is simple and most players get it wrong for a week:
- Fill before the job chain, not during it. A job that pays on completion pays nothing if the bike dies on the way.
- Never start a chain below half a tank. Half a tank is one long job plus a margin.
- Refuel at the station nearest your job board. Every station you pass that is not on your route is a detour you will not take later.
- Check oil at the same time, every time. Two gauges, one stop.
If a station is out of the way, the discount windows become more valuable: a 50% fuel discount justifies a detour that a full-price fill does not.
What Endless Fuel actually saves
The pass is blunt: mopeds never run out of fuel or oil. That removes three costs at once:
- The fuel bill. Every litre you would have bought.
- The oil bill. Smaller per unit, but permanent.
- The failure cost. The job you lost when the bike stopped, and the walk back.
For a player who rides every day, this is the highest-value pass in the store, and the money guide ranks it first for exactly that reason. For a player who logs in twice a week, it saves very little, because the fuel bill is proportional to how much you ride.
The honest calculation: estimate your fuel spend per session, multiply by the sessions you play in a month, and compare that to the Robux price. The pass is permanent and the fuel bill is not, so the break-even point arrives eventually for anyone who keeps playing.
Fuel and the rest of the loop
Fuel touches every other system in the game, which is why it deserves its own page:
- Jobs. A route is only profitable if the fuel it burns is smaller than the payout. Short chains near a station win.
- Tuning. A tuned engine is a thirstier engine in most games; the tuning guide explains the workshop side of it.
- Fines. A police stop costs euros that would otherwise be fuel. The police fines page covers the buffer you should keep.
- Garage space. More mopeds means more tanks to keep full. Three slots is a fuel budget, not just a storage limit.
How the 50% window changes your plan
The discount is short, so the way to use it is to plan around it rather than react to it:
- Fill both tanks at the start. A 30-minute window is long enough for two bikes if they are parked together.
- Ride a long chain inside the window. The discount only saves money on fuel you actually buy; if you fill up and log off, you saved money on a tank you were going to buy anyway.
- Do not detour to a distant station for the discount. A detour burns the fuel you just discounted, and the money guide treats travel time as the real cost.
If a second bike sits in the garage, the window is also the cheapest time to top it up. Two tanks, three slots, one discount.
When you run dry anyway
Everyone does it once. The bike stops, the job fails, and the walk back is the punishment. Two things make it less painful:
- Keep the phone on you. The store sells Phone Spawn Anywhere, which summons your moped, but a summoned moped with an empty tank still does not move. The pass fixes distance, not fuel.
- Do not abandon the bike. Ride back with fuel rather than buying a replacement. The garage system charges you for space, not for mistakes.
The habit that prevents all of it is the boring one: fill both tanks before the chain, every time, even when the gauge looks fine.
FAQ
How do you get fuel in German Moped Days? Buy it at a station pump. The display shows a price per litre, and the store occasionally sells a 30-minute 50% discount on fuel and oil.
Do you need two-stroke oil separately? Yes. Oil is its own tank and its own purchase, and the Endless Fuel pass explicitly covers both fuel and oil, which confirms they are two resources.
What is the correct mix ratio? In the real Simson S51 and Puch Maxi, 1:50, or 100 ml of oil per five litres of fuel. The game has not published whether it asks for a manual mix.
What happens if I run out of fuel? The moped stops and you lose the trip. Jobs pay on completion, so a dry tank can cost the payout as well as the time.
Is the Endless Fuel pass worth it? For daily players, yes: it removes the fuel bill, the oil bill and the stranding risk permanently. For occasional players, the savings are small because fuel spend scales with riding time.
Why is fuel so cheap in game? The pump board shows a themed price around 0.69 per litre instead of German pump prices. It is a game economy number, not a simulation.
