Proton SC insists pouring Petronas 15w50. Apa boleh buat. I bring my own EO ask them you want to void warranty issue a letter and sign it. I will accept the letter.why not compare with Petronas 5w40 also?
Inspira manual states 5w40. Idiots at Proton SC pour 15w50. Apa boleh buat :)You should've tried shell 15w50 too. Macam mana compare la.. And does inspira manual states 15w50 as its required EO? If not, you may wana burn down the SC or just think why 15w50 was even allowed to sip into your car lol
I had used both shell helix 10w40 and synthium 10w40 before. Honestly, no difference.
