how much extra will petrol go up

Petrol could go up by a few pence per litre to around 7p per litre if the current oil-price pressure continues, but the exact rise depends on where you are and whether this is a tax change or a market-driven jump. In the UK context, recent reporting said every $10 increase in oil can add roughly 7p a litre at the pump, while some markets have already seen much larger short-term increases from policy changes or local pricing moves.

What the latest reports suggest

• In the UK, analysts said a sustained oil rise could push average petrol toward 136p, then 140p+, and potentially closer to 150p if oil stays elevated.

• One recent report said petrol had already climbed 7% over a short period, from 132.8p to 141.5p a litre.

• In South Africa, one June update reported a petrol increase of R1.43 per litre.

• In Australia, a separate report said the ending of a fuel excise discount could raise costs further from July.

Why the answer changes

Petrol doesn’t rise by one universal amount worldwide; it depends on oil prices, taxes, exchange rates, refining margins, and local policy changes. That means the “extra” could be tiny in one place and much bigger in another.

Practical rule of thumb

• Small market move: about 1p to 7p per litre.
• Bigger market shock or policy change: 10p+ per litre.
• Local tax/discount changes: can be more than that.

What to watch next

If crude oil stays high for several weeks, pump prices usually follow with a lag. If you want the most useful estimate, the country matters most because petrol pricing rules are very different across regions.
