Castrol MAGNATEC Stop-Start 5W-30 C3 – Fully Synthetic Engine Oil (BMW Longlife-04 Approved)

Non-stop engine protection and improved fuel economy from every start

Modern urban driving with stop-start traffic puts constant strain on your engine. Even with the latest technology, stop-start conditions cause increased wear and reduce efficiency. Congestion has risen dramatically in the last decade, meaning your engine spends more time idling, restarting, and under stress.

Castrol MAGNATEC Stop-Start 5W-30 C3, with DUALOCK molecule technology and Castrol’s most advanced fully synthetic base oils, forms a powerful force field of wear protection. It dramatically reduces warm-up wear and stop-start wear by up to **50%**¹², while also improving fuel economy³.
