Quick answer: Castrol has three main ranges: EDGE, a fully synthetic and the top performer; Magnatec, with molecules that cling to the engine for start-up protection; and GTX for older cars and budget use. For modern and turbo engines choose EDGE; for everyday driving Magnatec is a balanced choice.
Castrol oil ranges
| Range | Type | Key grades | Best for |
| Castrol EDGE | Full synthetic with oil-film strengthening technology | 0W-20, 5W-30, 5W-40 | Modern cars, turbos, hard driving and high heat |
| Castrol Magnatec | Synthetic technology with molecules that cling to engine parts | 5W-30, 10W-40 | Daily use, city traffic and frequent stop-start |
| Castrol GTX | Mineral or semi-synthetic | 20W-50, 15W-40, 10W-40 | Older and high-mileage cars, lower budgets |

Why do so many people search for Castrol?
Castrol is one of the oldest and best-known brands and is approved by many manufacturers. But the name alone is not enough; what matters is the range, viscosity and approval. Castrol GTX 20W-50, for example, is wrong for a modern car that requires 0W-20, even though it is Castrol.
How to choose
- Modern car requiring 0W-20: Castrol EDGE 0W-20 with the required approval (e.g. dexos1 or ILSAC GF-6).
- Japanese or Korean car requiring 5W-30: EDGE 5W-30 or Magnatec 5W-30.
- European car: EDGE with the approval in your manual (e.g. C3 or VW 504/507).
- Older high-mileage car: Magnatec 10W-40 or GTX as the manufacturer recommends.
EDGE or Magnatec?
If your car is turbocharged or does long highway trips in summer, EDGE handles heat and stress better. If you mostly drive in the city with frequent stop-start, Magnatec gives excellent cold-start protection at a lower price.

FAQ
Is Castrol better than Mobil or Shell?
All three are strong brands. What matters is choosing the right range, viscosity and approval for your car, not the brand itself.
How many km does Castrol EDGE last?
Usually 7,000 to 10,000 km in our conditions, depending on driving and the manufacturer's recommendation.
Is GTX suitable for my new car?
Usually not. Modern cars need lighter oils such as 0W-20 or 5W-30; GTX is designed for older cars.
