偈油會否過期?

唔係未開封果d

係之前果次只行左2000km,但已經是1.5年多前,期間很少用車
會否變質?

顏色上,好似無乜問題.....

其實換一次機油仲平個你入一次油

有咩好擔心

Modern engines are sealed in a certain way.
There are lab tests show that storage time has little to do with engine oil quality, especially with modern synthetic polymer and additives technologies.
2 years period is common to German cars, whereas 3 years is acceptable.

I know a few friends who change their oils every 3 years in their 1960s cars.
However most ppl in HK will tell u to change regularly because it is what they had been doing for years but car condition is shttier than a 50 yrs old.

香港濕重,如果你副偈係完美密封就唔係太怕,但奈何唔係
油會濕左酸左,尤其用全合成冇咁穩定,既然有懷疑,換又唔貴,點解唔換左佢

我都係一年or一萬Km先換偈油加油格,全合成係5k Km先係最佳狀態,唔明啲人咁就換咗佢

原來run-in左既偈油咁有用,唔怪得車房會收返我換出黎既油喇,我都就快行到5千,平平地賣二舊水有無人要?
