Thanks for the info on the kit Paul. (I’ve never used any additives.)

I used to use Millers Classic 20w50 when my engine was 1st rebuilt (perfo block with 11D Shell bearings) but switched back to a Castrol SAE 30 monograde last year and the car uses/loses less oil now and I don’t use any other ‘additives’

The reason for the switch back to monograde (me and James Geddes decided) was down to having a Roger Williams oil pump fitted as when cold idling I have 4.25 bar (61.5 psi) and whilst running hot down a motorway at 60 mph the car still runs close to 3 bar (43 psi) and the crankshaft front oil thrower appears to struggle to cope with the multigrade but the bonus is that bottom of the car is still mildly lubricated, keeping the underseal soft.  🙂
