Yes, use the older style green antifreeze.

If you can buy the concentrate, not the premixed. Mix concentrate with distilled water. If you compare the prices, less expensive to mix it yourself instead of buying premix. If you save an used up container or 2 you can mix it up and have it ready if you have to add a little. Handy on longer trips to have some premixed in case you need it. Just remember to mark the container with a sharpie 50/50 mix, so you do not forget it is premixed.

Even though antifreeze really does not go bad if it is clean, some of the additives/rust protection/effectiveness has a life span of about 2- 3 years. Personally I drain/back flush every year before putting her down for the yearly winter nap, put the old back in with additive reconditioner. Change with fresh antifreeze every 4 - 5 years.
