Shell Helix HX7 ECT 5w-40 C3 Semi-Synthetic Engine Oil

Shell Helix HX7 ECT's synthetic technology formulation uses Shell's emissions-compatible technology to help petrol engine exhaust catalysts and keep diesel particulate filters clean, while protecting it from ash build-up that can block the exhaust system and lead to reduced engine performance. 

Shell Helix HX7 ECT 5w-40 C3 can be used for modern gasoline engines, diesel engines with particulate filters and gas engines.

    SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
    We've tried to keep all other shipping costs as low as we can.

    Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

    • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
    • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
    • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
