For the last six years l have been running with G13 antifreeze in a 1983 T25 petrol. Is this ok ?

Yes. Some suggest replacing with new every two years. In fact you can use any colour, blue or pink, or, in fact, any grade. As long as it's phosphate free. Just dont mix grades or colours.

You can mix G12 and G13.

Yes. My dont mix grades is a bit misleading. G11 too.
