The penrite will be fine. Just mix to the correct ratios.

G'day Kev.,
I've used the top of the range Tectalloy in both a 4.2d and 3.0 engine and am happy.
From what I can see the most important part of the exercise is to TOTALLY flush the old stuff out. Particularly if the new is of a different type. If you don't they can react and glue up and the donk's cactus big time.
Luck,
Col.

As above. You can get coolant that can last up to 40,000 Ks.
