Model V2 engines, usually smaller, are smaller and operate under different conditions than actual motorcycle or car engines. Therefore, the special needs of the model engine need to be considered when selecting lubricants.

How to select model V2 engine oil?

1. Light engine oil: Generally, model engines can use light engine oil, such as No. 2 engine oil. This oil has a lower viscosity and is suitable for high-speed operation of small engines.

2. Special oil for model engines: Some manufacturers offer lubricants specifically designed for model engines. Please go directly to your local model toy store for consultation. These lubricants may contain special additives to meet the unique needs of small engines. Check your model engine's owner's manual or manufacturer's recommendations to see if a specific brand or model of oil is recommended.

3. Avoid using oil that is too viscous: Since model engines usually run at higher rpm, oil that is too viscous may result in insufficient lubrication. Choose an oil of moderate viscosity to ensure an effective oil film inside the model engine.

4. Refer to Manufacturer's Recommendations: Always refer to the manufacturer's recommendations for your model engine. Manufacturers usually recommend using gasoline and two-stroke engine oil. If it is produced by Retrol or Microcosm, please lubricate it according to 25:1. If it is produced by Cison, please lubricate it according to 30:1 to ensure that the lubricant you choose meets the requirements. these requirements.

How to Lubricate a V Twin Engine Model?

Lubricating a v2 model engine, especially for cosmetic purposes, is usually a simple process. The following are steps to consider when lubricating a V-twin engine:

1. Check the documentation: Check out the engine owner's manual, which you can find from the official Stirlingkit Facebook group , or any accompanying documentation provided by the manufacturer, Cison or Retrol, Microcosm. In our FB group, a professional user, called Engine Man, suggest: “there is some lube in the crankcase. However, you can add some Molly Lube to it. Just make sure you open the crank slowly and carefully so gears do not get out of timing alignment. For the first full tank, run the fuel-to-oil ratio of 40 to 1. Then reduce 50 to 1 and after the 4th tank you can run a 60 to 1 ratio. What I do with my v twins is after 4 tanks or so, I tip them to their side where the crankcase venting hole is, put some tissue, and let the old oil drain out. Another tip from me is to run the engine where there is a cool air circulation or use a fan. I always run all of my engines with a small desk fan behind to provide the airflow. so you can add a very small amount of oil (3 ml) through that vent hole, however, that doesn't get into the cam gear. Those are in the front cam cover held with lots of small screws. You can lay the engine to the side keeping the cover facing up and remove the cover. Add Molly lube to the gears carefully) and put the cover back. That should provide a good level of lubrication and protection to cam lobes and gears. The rest is lubed with the oil in the fuel.”

2. Identify lubrication points: In a V-twin engine, common lubrication points may include the camshaft, crankshaft, bearings, and other moving parts. Carefully inspect the engine to identify these components. Lubricating oil can be added to this hole, but the crankcase underneath is not completely sealed, and oil may leak out. The lubrication can only reach the bearing. If you need to lubricate the crankshaft cam, you need to add a section of hose, so under normal circumstances, the cam is lubricated. Just use 25:1 mixed oil splash lubrication.

Please note: If the circuit board of the sensor is soaked in oil, it will become non-conductive, leaving the current nowhere to be released and eventually breakdown the Hall sensor. For example, the Cison straight-four engine has its own oil pump. all you need is just add two-stroke oil to the oil pump.

3. Choose the right lubricant: Choose the right lubricant for your small engine. Light oils designed for model engines are usually recommended. Make sure the lubricant is compatible with the materials used in the engine components.

4. Apply lubricant to moving parts: Using a fine-tip greaser or applicator, apply a small amount of lubricant to designated moving parts. Pay special attention to areas where friction may occur, such as cam lobes and bearings.

5. Operate the engine gently: After applying the lubricant, operate the engine gently to allow the oil to spread and cover the moving parts. Rotate the crankshaft or other relevant parts to ensure even distribution.

6. Wipe off excess lubricant: Check for excess lubricant and wipe it off with a clean, lint-free cloth. This helps prevent dirt and dust from accumulating on the model.

7. Periodic Inspections: Periodically inspect to ensure lubrication remains effective and there are no signs of wear or problems. Regular maintenance helps extend the life of your model's engine and keeps it running smoothly.
