Hi

 

Just wondering if this would be good for running in oil...

It would only be in there for 100 miles then filter/oil change

Would be fine for 100 miles id imagine!

I use comma classic, but the oil pressure at idle drops within 8 miles from 60 to 40psi

Half of that is at 60-70 mph

I was advised by people much more knowledgeable than me to use Castrol Classic to run in on.

I certainly wouldn't put that Weasel P**s in a brand new engine just to save £10.

Always use a quality 20w50 mineral oil at all times in a Mini, even for running in.

What cooperman said.

Comma sonic is £18 ish delivered from amazon. What's the point of penny pinching over what is arguably the most important component ?

[jt19]

I thought that if you use good oil to run in with, it won't bed the bores in?

[Cooperman]

I've always used top quality oil to run in Mini engines for over 50 years and I've never had a failure of the rings to 'bed in'.

[jt19]

Fair do's just something I read about bedding engines in.

 

What's your method cooperman may I ask?

[HarrysMini]

Cooperman was actually one person to recommend Castrol Classic to me, for running in. Drop it after 100 miles and start using Valvoline VR1.

That's what I do with modified engines, changing at 100 miles and again at 600 miles. Then it's Valvoline VR1 20w50 mineral.

For standard engines I usually run in with Castrol 20w50 for 200 to 250 miles, then drain and fill with the 'good stuff'.
