I want to flush my system and replace it with the Type 2. The Type 2 is only sold in 3.78 liter (1 US gallon) containers and is already mixed. In Canada it costs $14.18 each. That means if the Legend holds 2.3 gallons, I will have to buy 3 containers which end up costing $48.92 including the tax. That's not cheap. I have heard the Peak is the oem supplier for Honda. I'm going to check out what they offer and prices.

There are too many opinions about this subject and I don't have any concrete information. I called Honda Canada today and the representative said use only the original one (green) or it may damage the seals and gaskets, mind you he thought that Type 2 was made by an aftermarket company- not Honda. I may have to call again and speak with another more informed representative. I called an Acura dealer and the parts manager also said use the green one. I called another Acura dealer and they said they have only been using Type 2 since it came out. He also said that there was a service bulletin issued about it. I don't have the number of that Bulletin yet.

I called Peak and they said that they package the oem stuff for Honda.
