HI,
I used Car Plan 5 star. It's supposed to be one of the best. It's red in colour unlike most others that are blue. Most people use about 2 litres !
Cheers

Don't mix different types (ie colours) of antifreeze. Whereas the antifreeze properties do not age with time, it is the corrosion inhibiter additives that deteriorate with time, and more importantly become ineffective if different colours of antifreeze are mixed. ie if you mix for example the blue and red antifreezes your car will never freeze, but the resulting mix will be ineffective in preventing corrosion in your engine.
Most Japanese cars use use low or no silicate formulation antifreezes and use phosphates rather than silicates to prevent corrosion. Silicates are abrasive and can result in premature failure of seal materials, therefore the normal blue stuff is a big no-no.
Therefore best to stick to the OEM coolants for topping up and for changes.

Normally, the blue stuff is glycol based where as the Red is Methanol based.
I heard that Methanol was more agressive and would cause the rubber pipes to soften more, possible causing leaks ?
I know most new cars use the red stuff but isn't that just because its cheaper ?

I tried to work this one out recently for an MY96 .... my owners manual says glycol based antifreeze ... but it also says use only Subaru supplied ... but local dealer said they just use normal stuff and another dealer that serviced my legacy charged me for two litres of shell glycol so who knows??

My 1998 Scooby uses green antifreeze, not sure what base that uses but as the car has a FSSH I hope it is Subaru stuff. I am also unsure if it can be flushed and red stuff added?!?
