Will an OAT antifreeze cause problems with my 1978 MGB?
My 1978 MG MGB had an engine rebuild six months ago. An OAT antifreeze was put into it. I have read that this may cause a problem to older engines (water pump seals, gaskets, some solders and metal bearings). Is this likely to be a problem for my engine and should I have it changed for a silicate antifreeze?

As a rule of thumb, cars built before 1998 generally do not need an OAT-based antifreeze. Speaking from personal experience, I would recommend keeping it old school and using an anti-freeze that is non-OAT based and therefore does not contain silicate.
Is it true that antifreeze needs be changed at intervals these days.
I use Castrol XL30 monograde oil in my Ford E93A engine and bulk buying is cheaper. What would be the shelf life of the oil?
I am in the process of rebuilding an engine from the late 1940s. The recommendation, which I am following, is to use running-in oil for the first 500 miles...
