Yes, but if its not smoking one has to ponder where its all ending up?
In the old days when i were a lad, running old engines was the usual way of
things on old bangers my father had. Nobody cared about smoking engines then
of course.

Hi All

I have an old Audi A4 which consumes a lot of oil and has done for years.
MOT test fine and no obvious leaks nor particularly smokey. We have been
using 5w30 fully synthetic oil and to be honest given how long a litre of
it lasts (around 400 miles for a litre) I can't imagine whatever we put
in it would make much difference.

I have looked online and some seem to say to use this oil and some
mineral oil. Also, I was wondering if a thicker one would be better
(assume 5w40 is thicker?).

Will changing to a synthetic 5w40 or even to mineral oil make any
difference?

Any oil / engine buffs out there?

10/40 prolly work best

But when you get to that stage, you are just getting the last out of te
engine so any old **** will do.

Prolly valve seals or guides gone


Thanks

Lee.
