3 Klotz Oil Problems [Reasons and Solutions Explained]

Using Klotz oil to boost your engine can be great. However, Klotz oil can cause problems if not used right. 

So, how to fix Klotz oil problems?

Using Klotz oil you might run into problems like deadstick, or power failure. Also, there can be overheating issues. Hence you have to unclog the oil tank and clean the impure oil to fix it. After that, you need to refill the tank with well-measured oil. There might also be internal problems that need fixing.

Well, this was just a glimpse of the entire article. To know more in detail jump into the segment down below!

Mythbusting: Klotz Oil Can Not Damage Fuel Tank if Properly Mixed 

No, Klotz 2-stroke oil won’t damage the fuel tank if it’s properly mixed. The correct mixture will keep the engine functioning smoothly. That is by greasing the shaft walls and decreasing resistance.

Now if you have insufficient oil there won’t be enough to keep the engine running properly. Because less oil will mean there won’t be enough grease and can damage the motor.  

Moreover, the metals can thaw and possibly scrape against each other without oil.  There’s also a chance of motor instability due to a lack of oil. So, it’s important to get the right mixture of oil. 

Quick Fix 

Now insufficient oil can cause problems. But using excessive can cause much greater problems as well. So, here’s a quick solution for such a case.

Change Oil or Try Different Oil

Extra oil can develop a foggy exhaust, oil dripping out of the damper. Also, there can occasionally be a failure of power. Nonetheless, these problems can easily be fixed with the right blend of oil!

Usually, a two-cycle prototype requires a 40:1 gas-to-oil rate. For example, 3.2 liquid ounces of two-cycle oil for each one gallon of gasoline. However, some former types might need a 50:1 or 30:1 rate. 

You can check the motor housing for the suggested rate. Or a user manual can come in handy for the required rate.

Try Klotz Oil on Different Vehicle

Sometimes even using the right mixture can cause some problems. Then there’s a mix and match technique you can try to determine the cause.

Firstly, use the same oil in another vehicle. If it’s working then the problem is in the other vehicle’s engine. Otherwise, check your ratio and try using it again. 

Now there are a few problems you might run into with Klotz oil. Let’s check those out!

What Kind of Problem are You Running Into?

Now there might be some mechanical reason behind your problems rather than the oil. So let’s check out how to fix these!

Problem 1: Dead Stick Plane During Flight

During your flight, your plane has a deadstick. Now you might ask, why is my plane having a dead stick?

Your plane might have a dead stick due to motor loss of a single-engine airplane. This can be caused because of spark loss, air, or fuel. Moreover, this can happen when the engine isn’t getting enough oil or the tank’s dirty. 

Now, let’s break down the reasons. 

Reason 1: Clogged Oil Tank

Clogged oil tanks are one of the major causes of dead stick other than fuel shortage. Water, residue, and germs in airliner fuel tanks jam fuel stock cylinders and strainers. Eventually, the engines suffer from a shortage of essential fuel.

Moreover, the temperature might reduce during flight. This can result in water freezing at the base plugging the fuel channels. Fuel bugs develop a slime-like material that results in corrosion and can contaminate the structure. 

Reason 2: Impure Oil Mix

Sometimes even after you mix the oil right the engine fails to comply. Hence the question arises, is Klotz oil impure?

No, Klotz oil isn’t impure. However, the oil might get contaminated due to the dirty tank. Also, if the oil was exposed to surfactants it might become impure. For example, there might be truck cylinder cross pollution and fuel preservatives.

Moreover, there’s a chance of microbial expansion due to water exposure. Therefore, it might lead to corrosion in the fuel tank.

Fix: Clean the Fuel Tank & Line

Now the only fix to these problems is cleaning the tank thoroughly. Here’s how you can do it!

Step 01: Drain the Oil Tank

First, remove all the oil and slime from the tank. Next, set a pot under the valve. Pour water into the tank until the water runs clear. 

Step 02: Add Cleaner

You’ll now have to use a cleanser for the remaining residue. Usually, Trisodium phosphate is used for oil tanks. Because it’s strong on oil, mud, and slime and will definitely get rid of those. 

To help you out a bit, here are some great cleaners for your oil tank:

Now add the cleaner, fill your airline into the tank, and turn on the air tap. This will help the cleaner to reach every spot and get the slimes off. You need to run this for 12 hours.

After that, put a container under the duct valve and similarly rinse it with water.

Step 03: Dry the Tank and Refill the Oil

After running the water till it runs clean, you need to dry it. Otherwise, we’ll be back to square one with the corrosion and slime growth.

So to properly dry it you’ll first need 3 gallons of denatured alcohol. Pour this into the tank from every corner. This will absorb any remaining water. After that, install your air tube and turn the pump on. Now, set it for about an hour until the water has vaporized. Once your tank is waterless, reload it with fresh oil

Problem 2: Smokes Coming Out

Smoke coming out of your plane engine can be a sign of burnt oil. Or it could also be because of overheated exhaust. So, let’s check out the causes and fixes. 

Reason 1: Oil Burning Due to Overheating

Well, you might now ask, why is my engine overheating?

Your engine might be overheating due to damaged valve seals or piston rings. There can also be excessive oil in the tank or moisture in the exhaust tube. Moreover, there can also be damaged air filters, fuel injectors, or head gasket damage.  

You can identify the cause by seeing the color of the smoke. Here’s how:

  • Blue smoke: Damaged valve seals or piston rings
  • Black smoke: Excessive oil
  • White smoke: Moisture in the tube

Besides this, there’s another reason for smoke coming out. Let’s investigate!

Reason 2: Plane Overheating Due to Damaged Exhaust

A clogged exhaust would explain why smoke not coming out of exhaust. This is because there isn’t room for fresh air to get into the combustion compartments. Thus, excessive heat is generated in the engine and it won’t be able to run.

Now, this overheating can result due to a gap in the exhaust near the motor. The hot fumes can blaze right into different units causing heat damage and likely fire. 

Moreover, if engine coolant mixes with your oil it can result in overheating. This usually happens if you have a wrecked head gasket. So, you have to fix these!

Fix 1: Fixing the Exhaust and Engines Induction

Start by inspecting the exhaust and induction for possible leaks or damage. Check for corrosion, breaks, grains, or gaps. 

If the damage is minimal, use exhaust tape or epoxy to fix it. But before that, clean it with acetone. For rusts, spray the WD40 rust penetrator on the exhaust hooks to loosen the rust. Then just wipe it out with a cloth using a detergent solution.

However, if the damage is severe you might have to replace the exhaust pipe. Take help from a professional if you’re unsure about what to do.

Fix 2: Check the Coolant 

Now you need to inspect your coolant for oil substances. Check for a heavy, milky-like element. If you find any, you need to drain it completely and rinse the convector with water.

Furthermore, you’ll need to scan your oil dipstick. Use the oil suggested and refill your oil.  Also, apply “Hy-per Lube Oil Supplement” on your piston rings and valves. This will help to avoid any leaking issues in the future.  

Problem 3: Sudden Loss of Power or Torque

Now insufficient fuel or power can cause power failure or loss of torque. Let’s explore the whole issue in detail and find the solutions.

Reason 1: Not Meeting Fuel Requirements

Your engine might be getting less fuel and the mixture might be wrong. This can cause severe damages like inadequate condensation, jammed fuel strainer, polluted air filter, etc. Also, poor fuel pumps and bad injectors can be responsible for the failure. 

Reason 2: Improper Mix of Fuel

If your Klotz oil ratio isn’t proper then you’ll face some serious issues. There can be delay, stuttering, or failure of power in your vehicle. So to prevent any of this from happening we come with a handy chart!

Now, if your engine is not meeting these requirements, it might overrun. This can cause a delay in power.

Fix:  Proper Oil Mix for Plane

The proper mixture of oil can solve all your lagging or power failure issues. But when combining, can you mix 2 brands of 2 stroke oil?

Yes, you can mix 2 brands of 2 stroke oil. Any brands’ synthetic, semi-synthetic, and traditional 2-stroke oils are compatible. The only thing you have to keep in mind is the ratio. However, there might be a slight change in content in different brands’ products. So take that into account.

For a 2-cycle engine, you can use a 50:1 or 32:1 ratio. For a 50:1 ratio, use 1 gallon of gasoline with 2.6 US ounces of 2-cycle oil. In the case of 32:1 ratio, use  1-gallon gasoline with 4.0 US ounces of 2-cycle oil. 

Well, that’s about it for the measurements. 

Still Having Issues? Here’s the Final Step

Now, you’ve tried all the fixes but you’re still unable to solve this mystery. So, here’s one last thing for you to try out!

Disassemble Everything

First, disassemble everything in your vehicle’s engine. From cylinder head to fuel system remove everything. Check for clogs or dirt in the compartments of the fuel system.

Properly Clean

Next, clean everything properly. This includes the fuel filter, pump, injector, carburetor, fuel tank, etc. Then rinse the fuel pump, fuel pipes, and injectors by using the cleanser. Start the engine for the cleaner to run through like before.

After that, put the cleanser straight into the warm motor. The high temperature will loosen all the dirt. Then you can wipe out sludge and carbon residues from the combustors. 

Lastly, take the cleanser again to hand-rinse the air infusion. Use scrubs to peel off any ragged residues that obstruct airflow.

Make a New Oil Mix

Now make a completely new well-measured mixture that meets your engine requirement and refill it. By the way, you can also make a mix of alternative rc shock oils in this way. Now, refer to the user manual for oil ratio!

When mixing you might wonder, can you mix 2-cycle synthetic oil with regular?

Yes, you can mix 2-cycle synthetic oil with regular. Motor oil formulation is quite similar to synthetic oil. Hence when mixed, you won’t face any problem. However, performance-wise it might lag a bit compared to synthetic oils.


Finally, reassemble all the parts in the way you took them apart. Make sure the area is dust-free and clean. Then tighten all the pins, grease up the hoops and bolts before using. 

Pro Tips to Avoid Oil Problems

  • Use Klotz premix oil to avoid the hassle of mixing oil. Hence you’ll not have to worry about wrong measurements.
  • Prevent downpours while refueling. Also, make sure you leave room for oil to expand due to heat.
  • Change the fuel filter twice a year. 

Well, that wraps up all the problems you might be facing with Klotz oil!


Is Klotz Oil Good?

Yes, Klotz oil is good. Compared to store-bought fuel, this oil helps the engine to push harder and steadier. Besides, it causes no plug bowling, minimal heat, and decent rendition.

Can you mix Klotz and Amsoil?

Yes, you can mix Klotz and Amsoil without any issue. Since the oils’ bases are the same there won’t be any differences. However, try to maintain the oil ratio.  

Can you operate a car on methanol?

Yes, you can operate a car on methanol. This helps to consume extra heat and handles more pressure than gasoline. Thus this makes it ideal for incredibly hot-sprinting turbocharged motors.


Hope we’re successful in solving your Klotz oil problems. Additionally, you can use a secondary container made of concrete to avoid oil leaking. So that if the tank is overfilled or reserves water, the container can contain it safely.  

That’s all for today, take care!
