Quick answer: The higher the Shell Helix number, the higher the quality: HX5 is mineral, HX6 and HX7 are semi-synthetic or synthetic technology, HX8 is fully synthetic, and Helix Ultra is the top range, fully synthetic and made with PurePlus technology from natural gas. For modern cars choose HX8 or Ultra in the viscosity your owner's manual specifies.

What does "PurePlus" mean in Helix Ultra?
It is Shell's technology that converts natural gas into a very pure base oil with almost no impurities. The result keeps its viscosity in high heat and leaves fewer deposits, which matters in the Saudi summer.
How to choose the right Shell range
- Modern car (roughly post-2015) or turbo: HX8 or Ultra in the required viscosity.
- Japanese car requiring 0W-20: Ultra 0W-20 or HX8 0W-20.
- European car: Ultra with the approval in your manual (e.g. A3/B4, C3 or MB 229.5).
- Older high-mileage car: HX6 10W-40 or HX5 as the manufacturer recommends.
HX7 or HX8?
HX7 is a cheaper semi-synthetic suited to normal use. HX8 is fully synthetic, handles heat better and lasts longer between changes. If your manual requires a fully synthetic oil, do not drop to HX7.

FAQ
Is Helix Ultra worth the extra cost?
If your car is modern, turbocharged or drives a lot in the heat, yes. For simple older cars, HX7 or HX6 is enough.
How many km does Helix Ultra last?
Usually 8,000 to 10,000 km in our conditions, or as the manufacturer recommends.
Can I switch from HX6 to Ultra?
Yes. Moving up to a higher range in the same viscosity, or the one your manual specifies, is fine.
