الموضوع: سؤال عن صوت الموتور ؟؟؟

الاخوه الافاضل عندى العربيه صوت الموتور بيكون عالى جدا بعد 90 كم وبحس ان العزل الصوتى مش كويس هل ده طبيعى ولا العيب عندى مع العلم ان صوت الموتور على السلانسيه بيكون هادىء و طبيعى بس كل المشكله لما السرعه بتزيد بيبقى صوت الموتور مزعج .. ايه رأيكم؟؟؟

it maybe due too many factors but noway it is because of the cold weather cause cold weather means less heat and more performance !! so it maybe of the cold weather in case u put an engine oid not for the cold weather notice the grading on the oil and u will notice that it will change when the summer comes they will change to the hot weather grade oil ! and try to put the fully synthetic oil cuase it withstands many variations in weather change ! this is a point
second one since ur car is new then we can exclude the airfilter as a reason !
so i recommand if it is really disturbing u
to check the words i said about the oil grade and if u wanna buy one i recommand shell ultra 5w-40
5w-40 it means that it works great with out losing it`s viscousty starting from the temp. 5 till 40 and that`s the climate temp. not ur engine temp it is exactly for the current weather or maybe mobil but i noticed that it`s written on it 15w-50 or maybe 10w-50 so the 15w or 10w means that u have to warm ur car alittle more at the morning before taking off more than that with the 5w grade
