以下是摘錄紐約市VESPA論壇的對話:
scosgt:I change the oil in my SYM every 600 miles...
(我每600英里更換三洋機車的機油)
Brouhahaage 91 of the owner's manual.....Oil and oil filter, change every 3,750 miles or 12 months, whichever comes first.
(第91頁的偉士牌使用手冊表示機油更換時間為每3750英里或是12個月,以誰先到為準。)
papafern:maybe thats why some mechanics say that after 10k miles vespa engines suck. that means that at that mileage the oil has been changed only 3 times!!!!!!!!!!!(這也是為什麼有些技師表示超過一萬英里之後的偉士牌引擎的爛透了,這意味著在一萬英里以內,這台車只換過3次機油!!!!!!)
