Booklet 3.2 Tips and Advice
Engine oil consumption
I n ord er to provide effective lubri cation and
cooling of int ern al eng ine compo nents, all in­
t e rnal combu stion engines use a ce rtain amount
of oil. Oil co nsumpti on varies from en gi ne
to en ­
gine and may change significantly over the life of
th e e ngine. T ypicall y engin es whi ch have a
break -in period, us e mor e oi l during the break ­
in pe riod than they do after the break-in period,
wh en oil consumption has stabilized.
Vo lksw age n recommend s that you use the ty p e
of oil that m eets th e s pec ifica tion s described

of a ll of th ese vn riabl es, it is not p ossible to sp ecify standnrd or rate o f oil con­

the oil level in yo ur en g in e a t regu la r int erval s,
pr efe rabl y every time yo u re fu el, a nd alwa ys be­
fore going on

The oi l pre ssure light i s not an indicator of low

out or flashes while drivin g (above 1500 e ngin e
a buzzer will so und. It indicates that the

ate ly, check th e engine oil leve l and add oil if
n ecessa ry. If th e eng ine oil l eve l is no rmal, but
th e light continu es to flash, do not continu e to
operate the ve hicl e. Engine dama ge ma y occ ur.
If yo u believe your engine u ses excess ive
