If you need the short answer, use oil-only where oil, fuel, or hydraulic leaks are the main risk and water may be present, use universal for indoor maintenance with mixed fluids, and split the site by zone if both situations apply. The guide linked from the menu goes deeper on chemistry; this page is about the quicker buying decision.
30-Second Answer
What should I buy?
Use this page as the shortcut. If the answer is obvious, move on. If it is not, the matrix below will usually settle it.
Oil-only
Use this where oil, diesel, or hydraulic fluid is the main risk and water may be present. It is the better call near drains, bays, bunds, and outdoor storage.
Universal
Use this for indoor maintenance where you need one kit to handle mixed day-to-day fluids. It is the simpler choice when the spill is not water-adjacent.
Both
Use both when the site has separate zones. That is usually the lowest-friction answer for factories, estates, and multi-area operations.
Scenario Matrix
Where each kit belongs
The fastest way to choose is to match the kit to the space, not to the whole site.
| Environment | Best fit | Why |
|---|---|---|
| Fuel store or bund with standing water | Oil-only | Selective on hydrocarbons and less waste when water is present. |
| Loading bay or yard | Oil-only | Handles fuel or hydraulic leaks without soaking up rainwater. |
| Workshop or plant room | Universal | A practical default for mixed maintenance fluids indoors. |
| Warehouse aisle | Universal | Covers general leaks, drips, and handling spills in one kit. |
| Drain-side spill point | Oil-only | Better where contamination could reach drains or surface water. |
| Mixed site with indoor and outdoor areas | Both | Different zones usually justify different kit types. |
Practical Guidance
How to avoid the wrong purchase
These are the mistakes and trade-offs that usually decide the order.
Buying one type for the whole site
That works only if the whole site has the same liquid risks. Most sites do not.
Choosing universal for wet areas
Universal absorbs water too, so it can be the wrong call when the spill is outside or near drains.
Overspecifying chemical-grade kits
Chemical kits have a place, but they are not the best buy if your main risks are diesel, oil, and routine maintenance fluids.
If you only buy one
Buy oil-only if the biggest risk is outside or around drains. Buy universal if the biggest risk is indoor maintenance with mixed fluids. Then add the other type once the first zone is covered.
Refill compatibility
Keep refill packs matched to the kit colour and use case. Swapping grey refills into a white kit, or vice versa, muddies the response plan and makes restocking harder.
Cost logic
The cheapest kit is not always the cheapest response. A better question is: which kit reduces waste, restocking, and confusion in the area where it will actually be used?
Side By Side
Quick comparison
Short version: oil-only is selective, universal is broader, and the right answer often depends on the zone.
| Feature | Oil-Only | Universal |
|---|---|---|
| Main job | Hydrocarbons only | Mixed maintenance fluids |
| Water present? | Better choice | Not ideal near standing water |
| Typical location | Yards, drains, fuel areas | Workshops, plant rooms, warehouses |
| Colour | White | Grey |
| Refills | Keep white refills with white kits | Keep grey refills with grey kits |
| Cost logic | Best value where oil risk is concentrated | Best value where one kit must cover mixed indoor spills |
Need a site-specific answer?
If you are deciding between a single order or a mixed kit setup, we can map the areas for you and recommend the right split. That is usually faster than forcing one kit type across the whole site.
