How do I mix 2 stroke oil?

  1. Find out the correct type of fuel and fuel/oil ratio for your equipment. You should be able to find this in the Owner’s Manual or marked on the equipment itself. If in doubt, contact either the store you purchased the equipment from or themanufacturer.
  2. Purchase the correct fuel for your equipment in an approved container. Make sure you buy fuel in whole 1 litre units to make working our the correct/oil mix easy. Do not fill the container completely – leave some air space.
  3. Purchase Shell 2T oil. Measure the correct amount of oil based on the specified mix ratio for your equipment and the amount of fuel in your container, using the table below.

  4. Add the measured amount of Shell 2T oil into your approved petrol container. Seal the lid and gently shake the container to ensure the oil is mixed thoroughly with the fuel.
  5. Carefully add the fuel-oil mix into your equipment fuel tank using a funnel and you are ready to go! Remember to store your fuel container in a cool and secure location.

Other things to Note:

  1. Confirm that the equipment is fitted with a 2-stroke or 4-stroke engine. Some 2-stroke engines have a separate oil tank for the 2-stroke oil. They have automatic dosing pumps to treat the petrol in-line. In these cases the oil should not be pre-mixed with the petrol but used undiluted to fill the oil tank. Please make sure you know what type your engine is by referring to the Owner’s Manual, looking for the instructions on the equipment itself or contacting the retailer or manufacturer.
  2. Using the correct fuel-oil mix in a 2 stroke engine is critical to its operation. Too little oil could result in expensive engine damage. Too much oil could gum-up the engine and foul the spark plug, resulting in poor performance.

How do I do an oil change?

Changing your car oil is easier than it sounds and could also save you money in the long term. It shouldn’t take longer than 45 minutes – just make sure that you follow your manufacturer’s specific instructions and safety directions.

Firstly, choose the ideal oil for your car from the Shell Helix range by clicking here or using our Shell Lube Match tool here. Then check you have the necessary tools.

You’ll need

  • Shell Helix Engine Oil (4 or 5 liters – check owner’s manual)
  • New oil filter – check owner’s manual
  • Safety glasses and rubber gloves
  • Plastic container and funnel
  • Car jack and jack stands
  • Drain plug socket wrench
  • Paper towels and a rag
  • Oil filter wrench

What you have to do

  1. Prepare your car

    The car should be on a level surface with the parking brake on and engine off, leaving the oil to cool for a few minutes. If you need space under the car, jack it up and use jack stands to support it. Jacks on their own are very unstable – never get under your car without using jack stands. You could also put something underneath the engine to prevent spilling oil onto the ground.

  2. Unscrew the oil cap

    Locate the oil cap (check with the manual to locate it) and unscrew it. This is very important, as a vacuum will not allow all the oil to drain out.

  3. Locate the oil drain plug

    Get underneath the car and locate the oil drain plug. This is a lone bolt at the bottom of the oil sump.

  4. Place the container

    Place a container big enough to hold the oil beneath the oil drain plug and unscrew the plug, being careful not to let it fall into the container. Do not come in contact with the oil – it can be extremely hot.

  5. Drain out the old oil

    Allow all the oil to drain out. This can take several minutes.

  6. Locate the oil filter

    Locate the old oil filter with the help of your car’s owner manual. It should be identical to the one you are replacing it with.

  7. Remove the old oil filter

    Turn the filter wrench anti-clockwise to loosen the oil filter. The filter may be full of oil so take care not to spill any.

  8. Prepare the new filter

    Clean up the filter seat on the engine and place a light coating of oil on the gasket of the new filter.

  9. Install the new filter

    Carefully screw the new filter into place by hand, making sure it is not over-tight. Screw back in the oil drain plug and tighten it with the wrench.

  10. Fill up with oil

    Using the funnel, carefully fill the engine with Shell Helix, avoiding spillages. Measure the oil level with the dipstick after every two liters filled.

  11. Check the level is correct

    When you have reached the correct level, replace the oil cap. Turn on the engine for ten minutes and then off again. Check the oil level with the dipstick once again – if the level is low, add more oil.

  12. Clean up

    Clean up all oil spillages on your engine and check for any leaks from the drain plug.

  13. Properly dispose of the old oil and filter

    Used oil is highly toxic and must never be disposed of with domestic waste. It’s illegal to pour used oil into the sewage network. Put your used oil in a sealed container and label it. Then take it to an auto repair Centre, service station or recycling Centre. Most places will accept used oil for free.

Where can I dispose of my used oil?

You can take your used engine oil in a sealed leak-proof container to oil recycling drop-off bins throughout Auckland.  Visit to find out more information, and find a collection bin near you.

What are the features and benefits of synthetic oils?

Synthetic oils have excellent viscosity control and outstanding stability over a wider temperature range than mineral based oils.

  1. Low overall viscosity means reduced friction in the fluid, resulting in improved engine efficiency and fuel economy, and better flow at lower ambient temperatures.
  2. The viscosity of synthetic oils changes less with temperature compared with a normal mineral oil. This means that the oil does not become too thick when cold or too thin when hot, which reduces engines wear at temperature extremes.
  3. The good high-temperature properties of synthetic oils mean that they are less prone to thinning at high temperatures. This gives better protection at high engine speeds (rpm) and when heavily loaded.
