Common Pitfalls
Translation Traps (for Russian speakers)
- In Russian, 'бензин' directly translates to 'petrol/gasoline'. Do not use 'петрол', which is not a Russian word for fuel. 'Petroleum' in English is the raw crude oil, not the refined fuel.
Common Mistakes
- Using 'petrol' in the US expecting to be understood for car fuel (use 'gas' instead). Confusing 'petrol' with 'diesel'. Spelling error: 'petroll'.
