I've used pentosin E for full flushes of two Golfs (2015 and 2017). No issues. Prior to that, I used it for topping off. It's the right stuf being G13 regardless of slight color variation pink/purple.

Pros: no issues, right stuff

Vehicle: Volkswagen Golf

Proton original radiator is of very poor quality. Rust prone. Change it as soon and use premixed Toyota Coolant bought from Toyota Service Center to avoid fakes. Toyota SLLC and an aftermarket radiator will last the remaining lifetime of your Saga.

Pros: Toyota Coolant avoids fakes

Cons: Proton radiator poor quality

Mods: None, staying showroom stock. TCL Buyers Guide Negatives / future ownership issues: A) Valley Plate coolant leak: Look for pink crystals (dried coolant) underside of engine near where transmission meets up w engine. Also check upper radiator hose where it connects to radiator. Workaround: 50k/5 year coolant maintenance.

Cons: Valley Plate coolant leak

Vehicle: Lexus

I used 3 of those Pentosin blue with a bottle of Water Wetter and the rest is water.. my temp is 30 degree higher than it was before and I don't know what the heck it was in there before which is this yellow/green milky stuff, it sure kept the engine mostly below 180. But now I hit 220-230 easily

Pros: kept engine mostly below 180

Cons: temp 30 degree higher
