A Brief Comparison Table

My Experience With Prestone Vs Super Tech Coolant

I kicked off my coolant saga in April 2025, fed up with my pickup’s overheating after a brutal winter left rust in its radiator.

On April 15, I snagged Prestone All Vehicles coolant, a green jug boasting 10 years/300,000 miles, and after a thorough flush with my garden hose, I poured it in.

By April 20, my temp gauge held steady on a 2-hour highway drive to visit family—pure relief after months of worry.

Super Tech entered the scene on April 25, a yellow 50/50 mix from Walmart claiming 5 years/150,000 miles for my sedan.

It slid into the radiator effortlessly, and by April 30, my engine purred coolly, though I noticed the color seemed less vibrant than Prestone’s bold green.

May 10 hit with a scorching heatwave, and Prestone’s Cor-Guard technology kept my pickup’s aluminum parts rust-free, even after idling in traffic.

Super Tech did fine in my sedan, but I spotted a faint residue around the cap that I wiped off with an old rag.

On June 5, a rainy weekend drive tested their mettle—Prestone’s boil protection held firm at 265°F up a steep hill, while Super Tech managed but felt less confident on the same climb, making me sweat a little. July 1 brought a cross-town trip with both vehicles loaded for a picnic; Prestone’s universal mix adapted seamlessly to my truck and sedan, while Super Tech’s OE red variant for the sedan required precise matching to avoid gelling issues I’d read about online.

On July 3, I tackled a long haul in the pickup, and Prestone’s anti-foam agents kept bubbles at bay, unlike Super Tech, which showed slight foaming in my sedan’s overflow tank after a bumpy road.

 Now, at 01:55 PM +06 on July 07, 2025, after 83 days of city commutes, country drives, and garage tinkering, I’ve logged their strengths—Prestone’s longevity and versatility stand out, while Super Tech’s affordability tempts on a budget. You’ll see how they match your driving style, so let’s unpack my garage adventures in detail.
