# Calculate the mixing ratio correctly: oil calculator!

Even in times of electromobility, Euro 7 discussions and OPF filters, many mopeds, motorcycles and even cars are still like that Barkas, the Trabant or the Wartburg on our roads with one Two-stroke mixture have to drive in the tank. However, a mixture may also be necessary away from vehicles. For example in a lawnmower, in a brush cutter (brush cutter), in a chainsaw and even various emergency power generators and RC burners are available with a 2-stroke mixture. So that you can mixing ratio don't have to do the math yourself, you can find one here Calculator for the oil percentage.

## Oil calculator - two-stroke mixture

 Petrol mixing ratio PM1:20PM1:25PM1:33PM1:40PM1:50PM1:60PM1:100 Amount of oil

In order to be able to determine the correct amount of oil, the following steps are necessary. In indicate the amount of gasoline that you want to fill up. After that, put the specific mixing ratio and select "Calculate". At the very bottom is the amount of oil you need for the specified amount of gasoline. And in some cases there is still a ready-mixed canister, but with the mixing ratio not fit. In this case the calculator is able to work out how much oil you are using still add have to. Of course it is necessary to know what the mixing ratio is in the canister. The perfect mixing ratio is determined by the manufacturer of the vehicle or the implement and can easily be found in the manual or on the Internet. In some cases it is too a sticker on the vehicle appropriate that provides information.

The usual mixing ratio for vehicle engines under normal load is included PM1:50. Broken down it means that 50 parts of gasoline are added to one part of oil. The proportion of oil is around 2 %. For engines under heavier conditions more lubrication is needed and the ratio is included 1:40 or even 1:33. For tools such as the aforementioned chainsaw, the brush cutter but also for RC burners the usual mixture is included 1: 25 or 1: 40.

### even calculating yourself is not rocket science

In case you want to test your math skills and the mix ratio want to calculate yourself, you will also find the correct formula for this. This is a simple division. To simplify matters, it is recommended that you put the gasoline part in Milliliters specify, i.e. the liters with 1000th multiply, After that divide The result with the larger number from the determined mixing ratio. The bottom line is that The amount of oil in milliliters that you need.

• Here's an example: With a mixing ratio of 1:50 and 5 liters to the petrol required, the following is calculated:
5 liters * 1000 = 5000 milliliters.
5000 milliliters / 50 = 100 milliliters.
So you have to 100 milliliters of oil add to your gasoline to achieve a mixing ratio of PM1:50 to obtain.
• Important: Forget about it cannotthat you are well off your canister or tank after filling it with oil shake have to. The oil must mix properly, otherwise the engine may not be adequately lubricated.
• Ready mix: If you don't want to deal with the topic, you can also choose the one you want directly Buy ready mix. Either in the online shop, at the gas station, the hardware store or a car dealership / car workshop.

There are also motorcycles, scooters or implements that require manual mixing is not necessary. Newer vehicles in particular have one Separate lubrication (also called fresh oil lubrication / loss lubrication). So one tank for the oil and one for the gasoline. The mixture is prepared itself and fed to the engine via a pump during operation. Often there are no constant mixing ratio, as the engine adds more or less oil depending on the load. In such a system, the dosage is regulated either depending on the position of the throttle grip or speed / load-dependent.

### Common oils for separate lubrication

• Motul 710 2-stroke oil
• Castrol Power 1
• MANNOL 2-stroke universal
• Racing Dynamic Synthoil 2-stroke
• Motul 800 Off Road 2T

Not every 2-stroke oil is created equal. The area of ​​application (scooter, chainsaw, classic car, etc.) is decisive. A motocross motorcycle should be refueled with a different 2-stroke oil than a scooter. And the 2-stroke oil for the chainsaw is usually different from that for the outrageously expensive old-timer at home in the garage. The greatest differences arise from the division into the varieties fully synthetic, partially synthetic and mineral. Mineral oil is the cheapest, followed by a semi-synthetic oil and the most expensive is a fully synthetic oil. In any case, it is very important: If 2-stroke oil is prescribed, then it must just such be used. So tilt no 4-stroke oil or gear oil as an alternative to the gasoline.
