Can I use two oil additives at the same time?

If you want to use two oil additives, make sure to do so at an oil change interval. We also advise you to respect the recommended dosages to avoid over-additivized oil and engine runaway.

Which oil should I use for my engine?

Check the manufacturer car manual or find the information about the lubricant to use for your vehicle on: https://www.

Are all the additives compatible with all engines?

You cannot add oil additives in the following engines: PSA (EB) 1.2 PURETECH and (EP) 1.4 and 1.6 THP. The timing belt of these vehicles passes through the engine oil. Therefore, PSA prohibits the addition of any additive in the oil of the mentioned engines.

Can I add a larger dose of additive for a better result?

Overdosing an additive will not change the efficiency of the product. We recommend that you respect the dosage and the instructions for use indicated on each of our products.

Can I use an unopened product whose expiration date has passed?

We cannot guarantee the efficiency of a product whose expiration date has passed because its technical qualities may have been altered.
