Use mineral oil only, avoid semisynthetic.
For your gearbox either 10w40 or 20w50 are fine, its your engine that, being 20 yrs old, needs 20w50.
ok im going with 20w/50 and if its semi syinthetic then ill get the 10w/40 because if i rmber rightly that wasnt semisyinthetic but if i can ill go with 20w/50
i mean i dont realy know what differance it will make any way to me its just oil ive herd of people using some of the weirdest stuff to lubricate there old engines so as long as it proper engine oil it should be ok i mean its not gona be catstrothic if i used wrong one.........................
Im no expert but though Boris had a handbook with him saying use 10w40 id never put that in him
when we test drove him at the garage he was being sold at his
oil was old and gloopy i think 20w50,the garage did as promised a flush and
oil change but they followed their
autodata and used 10w40
The 10w40 they used was Synthetic
They thought they were doing us a favour but to be honest it caused leaks and the gearbox to slip
We have since Changed to Duckhams Q 20w50 Mineral and he doesnt leak so much and doesnt slip as much and is quieter too
All i can say is dont ever put synthetic/semi synthetic in a Mini and certainly not in an
Automatic Mini
regardless to what experts say i see it like this,boris may be a later injection mini but the engine and gearbox is more or less as it was launched and in those days they used 20w50 mineral so why change?
