Changing your car’s oil is a necessary, messy evil of vehicle maintenance. But what if we told you this “waste” is one of the most powerful, infinitely recyclable resources we throw away?
The amazing truth is that motor oil never wears out, it just gets dirty.
The contaminated oil sitting in your drain pan or a back corner of your garage has the potential to protect our unique environment and conserve massive amounts of energy. Here’s why you need to start treating used motor oil like the valuable liquid gold it is.
🤯 The Staggering Environmental Cost of Improper Disposal
The biggest reason to care about proper disposal is the sheer environmental devastation that even a small amount of oil can cause in New Zealand.
- The Waste Contamination Crisis – Used motor oil is loaded with hazardous contaminants like lead, arsenic and heavy metals. When it’s illegally poured down a drain, into the general rubbish (red/black bin), or onto the ground 0 It is guaranteed to cause harm to our waterways and soil.
- Shocking fact: Just one gallon (approx 3.7 litres) of used motor oil (the amount from an average oil change) can contaminate up to one million litres of fresh water. That is enough to provide a year’s supply for 50 people!
- The Energy Drain – The process of creating new motor oil form crude (virgin) oil is incredibly energy-intensive. It involves drilling, transporting and multiple complex refining processes. When we simply throw away used oil, we force the cycle to start over.
✅ The Powerful Case for Recycling (Re-Refining)
This is where the good news and the true meaning of sustainability comes in. Because oil only gets dirty, not worn out, it can be cleaned and re-efined into a new product again and again.
- Up to 90% Energy Savings – Recycling used oil into a new base lubricating oil takes up to 70-90% less energy than refining crude oil from scratch. By recycling, we significantly reduce the carbon footprint associated with oil production.
- A True Circular Economy Product – Re-refined oil subject to the same stringent performance standards as virgin oil, meaning the product you get it just as high-quality. Once it’s cleaned, the used oil can be:
- Re-fined into new lubricating oil (the best outcome)
- Processed and used as fuel for industrial heaters and boilers.
- Distilled into marine fuel or diesel.
How to Become a Motor Oil Recycler Today in New Zealand
If you do your own oil changes, proper recycling is easy. The key is to keep the used oil clean and separated from all other liquids.
- Drain & Store Cleanly: Drain the used oil into a clean, sealable containers. The empty plastic oil bottles you just bought are ideal! Crucially, never mix the oil with antifreeze, brake fluid, solvents or fuel. Contaminated oil can be difficult or impossible to recycle.
- Seal It Tight: Put the cap on tightly to prevent spills during transport.
- Find a Drop-Off Point: Take your sealed container to an approved collection facility. Great places to look across New Zealand include:
- Quick Lube Centres: Many service centres accept used oil for free.
- Auto Parts Stores: Retailers like Supercheap Auto and other independent motor factors often have drop-off points.
- Local Council Transfers stations/ Resource Recovery Centres: Check your local council’s website (e.g., Auckland Council, Wellington City Council) for your nearest public collection facility, as they often have dedicated storage for used oil.
Don’t forget to recycle the used oil filter and the plastic oil container too. Many of these places accept both.)
Making this one small change protects our drinking water, saves enormous amounts of energy, and closes the loop on a critical resource. Next time you change your oil, remember: you’re not throwing away waste; you’re harvesting a resource.
