What are Prestone’s core product categories?
Prestone specializes in two automotive essentials: windshield cleaning solutions and engine antifreeze. Their washer fluids target seasonal needs – summer formulas remove insect splatter (AS257) while winter variants prevent freezing (AS659). Antifreeze products like AF2100 offer -37°C protection using ethylene-glycol formulas compatible with multiple vehicle systems.

Prestone’s washer fluids contain surfactants that emulsify organic debris within 30 seconds, with pH-balanced formulas preventing rubber seal degradation. The antifreeze line utilizes Hybrid Organic Acid Technology (HOAT) for 5-year/250,000km protection. For heavy road trip users, the 6-bundle washer fluid pack provides 12L capacity – enough for 24-36 refills in standard reservoirs. Pro Tip: Always match antifreeze color to your vehicle’s existing coolant to prevent chemical incompatibility issues.
How do customers rate Prestone’s cleaning performance?
Users report 90% removal efficiency for hardened insect residues with Prestone’s AS257 washer fluid. The citrus-based formula leaves no streaks while its -0°C threshold makes it ideal for spring-fall use. However, some note reduced effectiveness on tree sap compared to specialized solvents.
Field tests show the AS659 winter formula maintains fluidity at -25°C, though its 0°C rating refers to storage stability rather than operational limits. The antifreeze line scores 4.7/5 for preventing radiator corrosion, with technicians praising its silicate-free formulation that won’t clog modern cooling systems. A common analogy: Using Prestone washer fluid is like applying dish soap to baked-on pans – it breaks down organic matter without abrasive scrubbing.
| Product | Capacity | Price |
|---|---|---|
| AS257 Washer Fluid | 2Lx2 | ¥38.61 |
| AF2100 Antifreeze | 3.78L | ¥59 |
What distinguishes Prestone’s antifreeze technology?
Prestone’s HOAT antifreeze combines organic acids with limited silicates, achieving 5x longer service life than conventional IAT coolants. The AF2045CN variant offers -30°C protection with nitrite-free corrosion inhibitors safe for aluminum components.

Their Extended Life formula maintains pH stability between 7.5-11 even after 160,000km, preventing electrolytic corrosion. The fluorescent yellow dye (AF2100) enables quick leak detection under UV light. Warning: Never mix different-colored antifreeze – the AF2100’s red pigment indicates hybrid technology incompatible with some OAT formulas.
