What makes you choose one over another ? The thickest synthetic I've found is
from Sellina (Fiat) who do a 20W/60 for racing that should hold prssure better.
Anyone know about Motul ? I've been warned off thick mono-grades by others
with vintage cars.

In which case it is going to have a regular sized sump, thermostat, cooler,
and an external and adjustable pressure relief. I can always add a larger sump
or another tank later on.

They also do one offs and are based in Slough just west of London. Phone

Thankyou for the advice - makes sense.
