Pupils at Seahorse Nursery School in Southfields received a visit from a tanker from a national fuel supplier, Certas Energy.
They saw the vehicle and its safety features.
Alex Ward, London regional manager for Certas Energy, said: 'The children at Seahorse Nursery School have seen our tankers driving around their area before, so they were really excited to take a closer look.
'It was also a great opportunity to teach them about how the oil these tankers carry plays a vital role in their community.'
Julia Wolfe, principal at Seahorse Nursery School, said: 'Our pupils relished the opportunity to look around a real oil tanker and find out how it all works.
'This tanker visit gave them the opportunity to learn about oil in a hands-on manner, complementing our teaching in the classroom.'
