My gardner's rod (pictured) caught the giant.
My boat was a 42 foot Performance with three F225 outboards by Yamaha
I needed a forth angler and he was standing at my door arriving for work and I aked him to come

Don't use the ST Blue. It's Prestone

Zerex is good, and so is Peak OET. If you can find them, Pentofrost A3 and Recochem OEM Blue are good, too.

ST blue is now in a Reochem bottle

I've used peak asian blue for a few years now, it's better than the green rusty iat I dumped out.

Is there a Xerex or Peak version of the latest Ford yellow?

the new Ford Yellow is just Prestone Cor-Guard, the yellow one that claims 300k.

What about a replacement for Volvo Penta yellow (boat engine).

Check in with your dealership on OEM...I'm guessing the price per gallon is similar enough to be negligible. I recently got Honda Type 2 for $2 more per gallon than what I would've paid for Zerex Asian blue at the auto store.

When I looked it seemed to me Preston Cor-Guard was a technology not a specific product.

Get a coolant that meets the engine manufacturer specs. SuperTech or Zerex or OEM.

For my Ford PSD I found 4 gallons of Ford Orange online for a decent price.

This. ^^^^
Check the back of the bottle. Does the Supertech meet the Nissan spec? If yes, you should be able to trust it. If no, I'd stay with the Zerex.

Personally, I use either OEM coolant from the dealership or Zerex. I've never had much confidence in the off brand coolants. I guess if you test your fluid regularly, the cheap brands of coolant may be ok.

The Prestone Cor-Guard in yellow container and the Ford yellow don't have the same chemicals in the SDS.
