After run oil?

[Three6ty]

Hi,
Quick question. Does anyone here use after run oil in their engines? I am using Magnum 20% at the moment for running in. Will no doubt will be going to 30% as time goes by.
Cheers, Rich

You should only really need it Rich if it is not going to get flown for a while, just going a few days in between should not give any real problems.
