>I am using "Mobil One" 0w -40w
Bob,
Page 10-9 of the 914 operators manual which covers Lubricants starts with:-
Oil: Motorcycle oil of a registered brand with gear additives. As far as I
can see from the Mobil.co.uk site, Mobil 1 is not a motorcycle oil.
Over the page on 10-10 fig 13 is a table giving multigrade weights according
to climatic conditions. 0W-40 is not listed.
In Rotax SI-914-019 there are two tables listing recommended oils. Read the
notes under the table and you will see that some are "recommended" while
others are "highly recommended" None of them are 10W-40. If you ask all
the UK 91x owners I suspect that you will find most are using Shell VSX4
10W40
