Product Information
Full details
This guide is for owners and mechanics of high-performance 2-stroke kart and bike engines, particularly those using Rotax Max or Honda TM engines. The Millers Oils KR 2T SAE 40 offers a significant performance boost through improved sealing, clean burning, and maximum lubricity. A potential consideration is its specific formulation, which may not be suitable for engines requiring ashless oils.

FAQs
What is the correct mixing ratio for Millers Oils KR 2T?
Always consult your specific engine manufacturer's manual. A common ratio for high-performance 2-stroke engines is 2% (50:1) or 3% (33:1), but verify with your engine's documentation.
Can I use this oil in my lawnmower?
Millers Oils KR 2T is designed for high-performance, high-revving 2-stroke engines like those in karts and performance bikes. It may be overkill or not ideal for standard lawnmower engines, which may have different lubrication needs. Check your lawnmower's manual for recommended oil specifications.
Is this oil suitable for all 2-stroke engines?
It is suitable for most high-performance air and water-cooled 2-stroke engines, and some outboard engines not requiring ashless oil. However, it is not recommended for engines that specifically mandate ashless or different viscosity oils.
Why is the oil dyed blue?
The blue dye is primarily for visual confirmation, helping to ensure that the oil has been correctly mixed with the fuel before it is put into the engine.
What does 'low ash' mean?
A low ash formulation means that when the oil burns during combustion, it leaves behind minimal residue (ash). This helps to keep the combustion chamber, piston rings, and exhaust port cleaner, improving performance and reducing the need for frequent cleaning.
What is the difference between SAE 40 and other viscosities?
SAE 40 refers to the viscosity grade of the oil. Higher numbers generally indicate a thicker oil. SAE 40 is a common and effective viscosity for many high-performance 2-stroke kart engines, offering a good balance of lubricity and flow.
Troubleshooting
Engine runs poorly or hesitates
Ensure the oil-fuel mixture ratio is correct and thoroughly mixed. Verify the fuel is fresh. Check for any fuel system blockages.
Excessive smoke from exhaust
While some smoke is normal for 2-stroke engines, excessive smoke might indicate an incorrect oil-fuel ratio (too rich) or an engine issue. Verify the ratio.
Throttle sticking
This oil is formulated to prevent throttle sticking. If it occurs, check the throttle cable and carb linkage for mechanical issues or external contaminants.
Difficulty starting engine
Check fuel delivery, spark plug condition, and ensure the oil-fuel mixture is correct. A correctly lubricated engine should not be overly difficult to start.
Pros and Cons
Pros
- Enhances power and torque through improved bore sealing.
- Ensures clean engine operation for better throttle response.
- Provides excellent wear protection with maximum lubricity.
- Prevents common issues like throttle sticking.
- Simplifies engine maintenance with reduced crankcase deposits.
- Officially approved for CIK-FIA racing.
Cons
- Not suitable for engines that specifically require ashless oils.
- SAE 40 viscosity may not be optimal for all 2-stroke applications in extreme temperatures.
- Requires correct pre-mixing with fuel, which can be a point of error if not done accurately.
Setup, Compatibility & Care
Setup: Millers Oils KR 2T is a pre-mix oil and must be mixed with fuel according to the engine manufacturer's recommendations. Typically, this is a ratio of 2% or 3% (50:1 or 33:1), but always consult your engine manual for the precise ratio. Ensure thorough mixing before fueling the engine.
Compatibility: This oil is specifically designed for high-performance 2-stroke kart and bike engines, including Rotax Max and Honda TM engines. It is suitable for air-cooled and water-cooled engines. It can be used in outboard engines that do not require ashless oils.
Care: Store the oil in a cool, dry place away from direct sunlight and extreme temperatures. Keep the container tightly sealed when not in use. The blue dye aids in visually confirming its presence in the fuel mixture.
