Reviews of Carlube parts For Business

it was 5/40w fully systhic carlube ive been adivsed to run 10/30w genetic oil? i will also use a mk3 oilfilter huseing with the sensors because then i can wire the oil temp up as well which i can keep an eye on

ive been to a company regards this problem , with crank bearing failure , ive had the oil pump , bores, pistons ,rings,, oil ways checked etc were fitted correctly...all they recomend is fit a external oil cooler to help keep the engine oil cool
