When you need five litres of 15W-40 mineral oil, the choice often comes down to the badge on the bottle. The price spread between these three options is less than five dollars, making this a straight fight between a house brand and two established names.
The house brand advantage
Supercheap Auto's own SCA brand takes the absolute price crown at $39.99. It is the cheapest way to get five litres of 15W-40 oil into your engine from this lineup.
However, the savings over a major brand are surprisingly slim. Valvoline's XLD Classic costs just $1.24 more. For many buyers, paying that tiny premium for a globally recognised oil brand is an easy decision.
Paying for the Nulon name
Nulon sits at the top of this pricing tier at $44.98. That makes the SCA oil 11.1% cheaper than the Nulon.
Without specific industry ratings or performance data to justify the extra cost, you are essentially paying for the Nulon badge. If you are already shopping at Bunnings, the Valvoline sits right next to it on the shelf and saves you $3.75.

Verdict
If you want to spend the absolute minimum, buy the SCA oil. But for just over a dollar more, the Valvoline offers a major brand name without stretching the budget to Nulon's price point.
