Hi, just now went to proton SC center ask about something.
Told them during my 25,000km service i want to use my own oil, is it ok or not? Then the guy told me that if the car still under 3 years warranty, then the warranty will be void if use your own oil. And i ask about headlamp, i told them i bring my own bulb, asked them to help me install can or not? Then he say ok, but with rm5 charge (thats fine), and AGAIN he said if the volt not same with the stock bulb, anything happen then warranty will void. I wondered is it proton that afraid of giving warranty to customer? Might as well dont give if so scare.
So i would like to ask is it my warranty will VOID if i bring my own engine oil and my own bulb?

ic so both warranty wont void, then next time when i go there with my own engine oil and own bulb, just dont care and ask them change only? Scare nanti they give look
