How it works

More about the test
  1. Order your card

    Posted within 1–2 working days, with free UK delivery.

  2. Add one drop of oil

    Use the dipstick to put a single drop of engine oil in the circle on the card, as the instructions show.

  3. Let it develop

    The drop spreads through the card. Leave it for the time given in the instructions.

  4. Scan it at a testing point

    Take the card to an EngineIQ testing point, such as a partner garage or kiosk, and scan it.

  5. Read your report

    Your report arrives by email, with a plain-English explanation of what it indicates.

What the test can and can't tell you

It can

  • Give an indication of the condition of your engine oil.
  • Screen for signs that can point to problems worth a closer look.
  • Help you decide whether a mechanic's inspection or a laboratory oil analysis is worth doing.

It can't

  • Replace a mechanical inspection. It isn't a diagnosis of a fault.
  • Guarantee the condition of an engine, even when the result is normal.
  • Tell you about parts of the car that the engine oil doesn't reach.

What can the test tell me?

It gives an indication of the condition of your engine oil and screens for signs that can point to problems worth a closer look. [TO CONFIRM: supplier-approved list of what the test screens for] It isn't a mechanical inspection or a diagnosis, and a normal result doesn't guarantee the engine's condition.
