# FAQ: Do 85cc Bike Need More Fuel Oil Than A 300cc?

## How much oil do you put in a 2 stroke dirt bike?

How Much Oil Does Your Dirt Bike Need? The premix ratio that you use will depend on the kind of performance that you expect from your dirt bike. Most brands recommend a ratio of 32:1 for two-stroke engines, but some modern bikes work best with a ratio of 60:1.

## Does 32 1 or 40/1 have more oil?

32:1 means that there is 32 times more gas than the oil you ‘re putting in. One gallon of gas = 128 ounces. Therefore 128/32= 4 (ounces that is). Or, 128/40= 3.2 ounces.

## What is the oil ratio for KTM 300?

With an average fuel-to-oil ratio of 1:80, an oil capacity of about 0.7 liters is sufficient for at least five tanks of fuel. Pre-mixing 2-stroke fuel is a thing of the past for KTM XC-W TPI owners.

## What happens if you put too much oil in 2 stroke gas?

Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power. While not ideal, these issues can be fixed by simply replacing the fuel in the tank with properly mixed fuel.

## What is better 2-stroke or 4-stroke?

Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable. That being said, 2-stroke engines are more powerful. Two-stroke engines require pre-mixing of oil and fuel, while the 4-strokes do not.

## Can I use 4-stroke oil in a 2-stroke gearbox?

A 4-stroke oil will flow from the crankcase to the engine components to be lubricated and then come back into the crankcase. Using a 4-stroke oil in a 2-stroke engine can therefore disrupt combustion and cause smoke formation and engine degradation.

## What does 50/1 mean when mixing gas and oil?

The mix ratio is the proportion of gas to oil, expressed as a ratio. For example, 50:1 means 50 parts gas to 1 part oil.

## How much oil do I need for a 50 to 1 ratio?

For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas.

## What is the premix ratio for 2 stroke?

Use a 40:1 two -cycle oil mix ratio. One gallon of gasoline combined with 3.2 oz of two-cycle engine oil. Unsure of the age of your equipment?

## What is the best mixture for a 2 stroke dirt bike?

Most owner’s manuals will tell you, but ratios between 32:1 and 40:1 are common. Thus, your mix is 40 parts gasoline to one part oil. If you’re working with the metric system, it’s easy: 10cc of oil to 400cc of fuel.

## What oil does a KTM 300 take?

Recommended fuel/oil ratio is 60:1 using a high grade 2-stroke oil. Manufacturer recommends full synthetic.

## How long will a 2 stroke run without oil?

The presence of oil and its distribution is absolutely crucial to an engines continued operation. Engines can work without oil, but the effect is so damaging they are only capable of running for less than 30 minutes until failing – and in most cases, it’s a lot quicker than that.

## What happens if you put too much oil in an outboard motor?

What happens when you fill your marine engine with too much oil is the pressure inside the engine begins to build due to the windage in the crankcase and the oil pump. This places great strain on rear main bearing seal. Even after just a couple uses, the seal breaks and the engine will start to leak marine engine oil.

## Can you fix a 2 stroke engine that ran straight gas?

First of all dump out all the fuel from the tank. Then refill the tank with the proper fuel oil mix. Pump the primer bulb until you see fuel in it and pump it a few more times to get any straight gas out of the carburetor and back into the tank where it can be diluted.
