I need to flush the coolant/antifreeze on old Brownie, my '91 F350. Truck is new to me and I don't know how old the coolant is, but it's green ethylene glycol and the truck has been off the road and used around a farm for about 10 years. Figure the coolant is likely 10+ years old.
I plan to use low silicate green ethylene glycol antifreeze and add SCAs, but I'm curious about what low silicate antifreeze y'all are using.
There's the Napa stuff, which some say is low silicate, but neither the website nor the jug say anything about low silicate, at least not that I can see. https://www.napaonline.com/en/p/NAF1GAL
Then there's Zerex, which states that it is low silicate on the jug. https://shop.valvolineglobal.com/products/zerex-original-green-concentrate-antifreeze
Am I missing anything or are these the only two out there? Other threads mentioned Motorcraft antifreeze but not sure it's low silicate.
Thanks,
Scott
