Peak Final Charge Pro-Series for Kubota?

[Fredward]

Hey, guys. I have a bunch of equipment maintenance to do this fall, and I'm going to start stocking up on fluids and filters. I've been using Peak Final Charge Global in my Kubota M7060 and two RTV-X900s. I do a radiator drain-and-fill every 2 years. I've never done an actual flush.

When I started checking prices and looking up products, I noticed that Final Charge Global isn't being stocked by Wal-Mart or any of the usual auto parts stores in my area. I started reading up, and it seems Global is being phased out in favor of Pro-Series. I can still buy the Global Concentrate on Amazon for a reasonable price, but I'm not sure if I should just go ahead and make the switch to Pro-Series.

I've pulled up the spec sheets on both coolants, and both products claim to be compatible with ALL heavy-duty diesel, gasoline, and natural gas engines. Global explicitly claims to be Kubota compatible while Pro-Series does not. Global is nitrate-, phosphate-, silicate-, borate-, and 2-EHA-free. Pro-Series only claims to be nitrate-, and 2-EHA-free. However, I've read that phosphated coolants tend to be desirable for Asian engines, as long as they aren't mixed with hard water. On the other hand, I've read that silicates can cause problems due to deposits and scaling, and that Asian manufactures tend to recommend against them.

I've gone through previous threads on Kubota coolants, here and on other forums. The consensus seems to be that they aren't too picky. They don't have sleeves or use unusual metals or seals. Kubota gives very vague coolant recommendations. "Ethylene Glycol Long-Life Coolant" is about the jist of it. So, what do you guys think? Should I buy some Global concentrate online, or just switch over to Pro-Series, which I can pick up at local retailers? Which do you guys think would be better? If I switch to Pro-Series, is it fine to do another drain-and-fill, or do I really need to perform a flush?

I'm not a fan of the PRO's composition, I would say avoid it. I find it intriguing that the silicated PRO has a longer service life (1.5 million miles) compared to the silicate-free Global. Silicates are really something to be avoided and it's weird to me that they're making a comeback in the coolant industry with these new PSi-OAT formulations. Silicates create a thermal blanket in the cooling system and heat transfer is compromised, permanently because it's dang near impossible to get the stuff flushed completely out safely. If you examine the descriptions again, you'll see that Global mentions superior heat transfer for engines that have EGR/SCR, while PRO makes no mention of it. Global is the superior product here.

For what its worth I've had the standard Prestone All vehicles 10yr/300k in my Kubota since 2020 with no issues. I did a full flush with distilled water and converted it over. No issues to report and the 2-EHA hasn't turned anything to jelly so far as I can tell.. Why do a drain/fill every 2 years with a long life coolant?? I think you'll be fine with either coolant choice and that the internet is right.. Kubota's aren't picky.

It sounds like you have good feelings using your current Global. If your only decision point at this moment is easy availability at Walmart, etc., my decision would be to stick with the Global for now and develop a plan in case Global should disappear in the future. Easy, peasy - put your mind to rest on this topic.

In my quick search, I can still get Global locally at Oreilly's, NAPA, AutoZone, and Advanced Auto. Mail order from Amazon or Zoro are easy options also.

Another reason to stay with Global is that you won't have to do a thorough flush - I think most here agree that its best to do a total flush when changing coolant chemistries. My workplace tractors accumulate low annual hours (120 +/-) and

I use John Deere Cool Gard II in all my workplace tractors to avoid analysis paralysis. These tractors accumulate low annual hours (120 +/-) and I extend the change interval to 4 years.
