Best type of oil for cold starts?

[Smallfry]

Might be that a cold start device has altered the timing as its extra cold. As it warms up it sounds less like a bag o ****e.

One of mine does the same. Best not to rev it very hard for the first few minutes, and on starting, let it run for a few seconds while the oil wakes up.

As far as I know the glow plugs on these heat up fully at first and then taper off after a few minutes, I'll definitely have a measure up and see if one of the new ones or the relay have failed.
I never rev the arsx off a cold engine especially this one
