5/40 synthetic ..
( Granville Hypalube Fully Synthetic 5W/40 .. 5.ltr @ £16.32 )
went for the '40' as it were recommended for a ron-box equipped motor
'synthetic' as it has much less tendency to hang about a surface
and coke-up from heat ..
mainly had the turbo in mind .. and the sensors that may get splashed with hot oil
motor gets 60mil of extralube zx1 every oil change ( @ 6k mile )
currently 180k+ on odometer .. engine running and sounding fine ..
