Frequently asked questions
Which treatment should I choose for my engine?
Start with your need: lubrication, fuel-system care, injector cleaning or preparation for an oil change. Then check the product label and the vehicle manufacturer's recommendations.
How do I use a Lubysil additive?
Where to apply it and how much to use depend on the product and vehicle. A fuel treatment must not be used as an oil treatment. Read the label and follow the recommended dose.
Can a treatment replace a repair?
No. A maintenance product cannot replace a mechanical diagnosis or a necessary repair. If a warning light or fault appears, consult a professional.
How are delivery costs calculated?
Delivery costs depend on your delivery country and basket items. Delivery costs and the total including VAT are shown before payment.
Can I ask for advice before ordering?
Yes. Have your vehicle model and engine details ready, then contact Lubysil with your question.
Need specific guidance?
The product page and its instructions take priority when choosing and applying a treatment.
