Oil & Gas Measuring Cups FAQ

What are oil and gas measuring cups used for in boating?

Oil and gas measuring cups (or an “engine oil measuring container” or an “oil gas mixer”) are used in boating to accurately measure the amount of oil or gasoline that is being added to the engine or fuel tank. This is important for a number of reasons.

• First, it is important to use the correct amount of oil or gasoline in order to ensure that the engine is running smoothly and efficiently. Using too much or too little can cause problems with the engine performance and can even lead to damage.
• Second, accurately measuring the amount of oil or gasoline being added with an oil measuring bottle can help to prevent spills or leaks, which can be dangerous and potentially damaging to the boat and its surroundings.

Oil and gas measuring bottles are typically made of a durable material such as plastic or metal, and have clearly marked measurements in fluid ounces or milliliters to make it easy to accurately measure the amount of oil or gasoline needed. They may also have features such as a spout or handle to make it easier to pour the oil or gasoline into the engine or fuel tank.

What should I look for in a 2-stroke oil measurement bottle?

When looking for a 2 stroke measurement bottle, there are a few key features that you should consider:

1. Accuracy: It is important to choose a bottle that is accurate in its measurements, so that you can be sure you are adding the correct amount of oil to your fuel mixture. Look for a bottle with clearly marked measurements in fluid ounces or milliliters.
2. Durability: A 2-stroke measurement bottle should be made of a durable material such as plastic or metal, so that it can withstand the rigors of use in a marine environment.
3. Ease of use: Look for a bottle with features such as a spout or handle that make it easy to pour the oil into the fuel tank or measure out the correct amount.
4. Compatibility: Make sure that the bottle you choose is compatible with the type of oil you will be using. Some bottles are specifically designed for use with synthetic oils, while others may be suitable for use with any type of 2-stroke oil.
5. Capacity: Consider the size of the bottle you need based on the size of your fuel tank and how often you will be using it. A larger bottle may be more convenient if you need to add oil to your fuel mixture frequently, while a smaller bottle may be more portable and easier to store.

What should I look for in a gas funnel for boats?

When shopping for gasoline funnels for boats, there are several factors to consider:

1. Compatibility: Make sure the boat gas funnel is compatible with the type of fuel you will be using. Some funnels are designed for specific types of fuel, such as gasoline or diesel, while others are more versatile and can handle a variety of fuels.
2. Size and capacity: Consider the size of the funnel and its capacity to hold fuel. A larger gasoline funnel may be more convenient for filling larger tanks, but it may also be more cumbersome to carry around.
3. Material: Look for a funnel made with durable materials that can withstand the harsh conditions of the marine environment. Plastic funnels may be more lightweight and less expensive, but they may not be as durable as metal funnels.
4. Spout design: Consider the design of the spout, which is the part of the funnel that goes into the fuel tank. A spout with a narrow, pointed tip can help prevent spills, while a wider spout may be easier to use but may be more prone to spilling.
5. Ease of use: Consider the ease of use of the funnel. Some funnels may have features such as a built-in screen to filter out debris, or a flexible neck that allows you to reach into tight spaces.
6. Cost: As with any purchase, consider your budget when shopping for a gas funnel. Higher-priced funnels may offer more features and better quality, but you'll need to weigh these benefits against your needs and available funds.

Why do 2 stroke engines use a gas and oil mixture?

Two-stroke engines use a fuel-oil mixture because the oil serves two important functions in the engine.

First, the oil provides lubrication for the moving parts of the engine. In a two-stroke engine, the crankcase is not separated from the combustion chamber, so the oil must be mixed with the fuel in order to be delivered to the parts of the engine that need lubrication.

Second, the oil helps to seal the combustion chamber and prevent the fuel from escaping. In a two-stroke engine, the fuel is burnt in a single stroke of the piston, so it is important that the fuel is completely burned in order to get the maximum power output from the engine. The oil helps to seal the combustion chamber and ensure that the fuel is burned completely.

It is important to use the correct ratio of fuel to oil in a two-stroke engine in order to ensure that the engine is running smoothly and efficiently by using a 2 stroke oil measuring cup. Using too much or too little oil can cause problems with the engine performance and can even lead to damage.

What absorbs motor oil?

There are several materials that can be used to absorb motor oil, including:

1. Oil absorbent pads, absorbent mats for oil, and rolls: Oil absorbant pads are made from materials like polypropylene or cellulose, which are highly absorbent and can quickly soak up oil spills.
2. Clay-based absorbents: These are made from bentonite clay, which is highly absorbent and can effectively soak up oil spills.
3. Oil-only absorbents: These are made from materials that are specifically designed to absorb oil and other petroleum-based substances, but not water. They are often used in marine environments to prevent oil spills from contaminating the water.
4. Boom barriers: These are floating barriers that are used to contain and absorb oil spills in bodies of water. They are made from materials like polypropylene or polyurethane, which are highly absorbent and can effectively soak up oil.
5. Sorbent socks: These are long, tube-shaped absorbents that can be placed around oil spills to contain and absorb them. They are made from materials like polypropylene or cellulose, which are highly absorbent and can quickly soak up oil.

It's important to use the right type of absorbent material for the specific type of spill you are dealing with. For example, oil only absorbent pads may not be effective for certain types of spills that other sorbents are designed for.

Is winterizing my outboard engine important?

Properly winterizing your outboard engine is the best way to prevent damage during the offseason from both lack of use and cold winter temperatures — depending on where you live. It also helps you with a smooth start to the beginning of next season.

There are seven basic steps to a proper winterization of your outboard engine:

• Thoroughly flush your engine with fresh water
• Stabilize the entire fuel system with fuel stabilizers
• Fog your engine
• Change the spark plugs
• Change the lower unit gear lube
• Disconnect your lead acid batteries
• Cover your engine with a fitted outboard cover
• Secure your outboard with a motor lock

With your engine properly winterized, there shouldn’t be any harmful debris or materials in the engine components that can cause damage over the off-season months. Plus, with new spark plugs, oil, and fluids, your outboard should start up right away when boating season starts in the spring or Summer.

How do I choose the right marine fuel for my Yamaha outboard engine?

Using the right marine fuel for your Yamaha outboard engine is essential for reliable and optimal performance on the water.

Because different makes and models of boat engines require different fuels, using the wrong boat fuel can cause significant damage to internal outboard engine components as well as your boat’s fuel system.

For many boat owners, it’s common to feel a bit unsure as to which type of marine fuel is right for their engine(s). Choosing between different ethanol levels, mixing oil with fuel, and even using diesel can be downright confusing.

The following are the most common types of marine fuels for your boat:

• Ethanol-Free Gasoline
• E10 Fuel
• E15 Fuel
• Oil and Gas Mixtures
• Diesel Fuel
• Marine Gas Oil (MGO) and Marine Diesel Oil (MDO)

How do I service my 2-stroke outboard fuel system? 

Use a filter wrench to loosen the existing filter element and use caution when removing it as it will be filled with gasoline. A clear plastic or glass container is helpful to dump the filter and examine the contents. A small amount of debris is common, as is a small amount of water after the fuel has had a moment to settle. More significant amounts of water would warrant further investigation.

If your filter’s mounting location allows it, pre-fill the replacement filter with some gasoline to make re-priming the fuel system easier. It is also advisable to use a small amount of marine grease or engine oil to lubricate the o-ring before installation. Spin on and hand tighten only about a half turn to snug.

Move back to the engine and locate the filter element(s) on the engine. The scope of this service will only include the low-pressure fuel filter and fuel water separator if applicable by model. It’s recommended by expert mechanics that owners do not service their high-pressure fuel filters. Depending on your engine model, the water separator filter (or castle filter) may be removed by using a wrench, standard tools, and a little caution. Unplug the water-in-fuel sensor if applicable and spin the cap off of the housing. Replace the filter element with a fresh one, lube the o-ring with grease or oil, and carefully reinstall the cap.

For most other models, the low-pressure fuel filter is inline where the fuel supply line passes down the side of the cowling. On applicable models, locate the Schrader valve on the fuel system. Cover the valve with a rag or towel and depress the valve stem to vent the pressure from the system before service. With the pressure vented, remove the inline filter and replace it with a new one paying attention to locate the clamps or zip ties securing the hoses to the filter.

Locate your engine’s primer bulb if applicable and use the primer to pump up the fuel system. You should feel and hear gasoline entering and filling the filter cup. Check for leaks and prime until the bulb becomes firm.
