Premium Canadian-made BOSS 50/50 prediluted antifreeze/coolants – choose from traditional Universal Green (conventional hybrid technology) or advanced Extended Life Red (long-life OAT formula). Both are ready-to-use ethylene glycol-based coolants pre-blended with high-purity deionized water and pre-charged SCA (Supplemental Coolant Additive) packages to deliver superior year-round freeze/boil-over protection, outstanding corrosion inhibition, and extended water pump life in passenger cars, light trucks, SUVs, heavy-duty diesel, fleet, agricultural, and off-road equipment – even under the toughest Canadian winter and summer conditions.

Both formulas provide proven protection against rust, corrosion, cavitation, liner pitting, scale buildup, electrolysis, and overheating while maintaining excellent heat transfer and compatibility with all cooling system metals (aluminum, brass, copper, solder, steel, cast iron) and gasket/seal materials.

✅ Key Benefits:

  • Ready-to-use 50/50 – just pour, no mixing required
  • Freeze protection down to –37°C / boil-over protection to +127°C (with 15 psi radiator cap)
  • Pre-charged SCA for immediate heavy-duty diesel protection
  • Superior multi-metal corrosion protection – including aluminum wet-sleeve liners
  • Excellent water pump lubrication and extended seal life
  • Prevents scale, deposits, and foaming
  • Outstanding heat transfer properties

Valuable perspective; moving; beautiful
Format: Hardcover
I loved this book. I devoured the entire thing in one sitting on a Sunday afternoon. It's a beautiful and tragic and warm story all at the same time. I feel like a lot of times when we hear about the Vietnam war in the United States, it's told from the perspective of American soldiers rather than the Southern Vietnamese who lost their home land. Really refreshing to see this diverse and nuanced perspective. I look forward to Thi Bui's future works.

This book healed me
Format: Paperback
Beautifully written and illustrated. Although Thi Bui and I have astronomically different life experiences, I still found I could relate on a deeply personal level. This book taught me empathy and forgiveness at a time in my life where I struggled to have it. Bui nailed the complicated feelings and emotions that comes with confronting abuse, abusers (who happen to be your parents), and the painful impact of generational trauma on both the parent and child. Highly recommend this book to anyone who is on a path of healing their own broken heart.

Powerful Family History
Format: Paperback
After the birth of her son, Thi Bui feels an increased sense of urgency about learning the stories of her own parents. Like all but her youngest sibling, she was born in Vietnam, though the children came of age in the United States. While the war itself haunts all of them, was the reason they left their homeland, the wounds her parents bear go far beyond the military conflict. This was only the second graphic novel I’ve ever read (both have been memoirs), and like the first was also selected by my book club. I feel like the limitations of the format mean it will always be a less preferred one for me, because I found myself wanting more words, more depth to the writing itself. But the story is deeply compelling, detailing her father’s brutal childhood, her mother’s much softer one, how they came together, and how the Vietnam War disrupted the future they thought they might have. It’s not as straightforward as “Americans bad”, and Bui is not afraid of the moral ambiguity of that time and place, where the best interests of the majority of the Vietnamese people was an open question for larger forces that seemed to have little room for consideration of what might have actually made regular lives easier to lead. And apart from the larger geopolitical machinations around them, the family had their own share of tragedy, including the death of their first child and a later stillbirth. But three living children and another on the way was enough for her parents to make frantic arrangements to leave, finally succeeding and eventually making their way to the United States. But of course, that was not the end of their story, just the beginning of a new chapter. Bui’s childhood as she depicts it makes it clear that it wasn’t the stuff dreams are made of, but what shines through is her tremendous empathy for her parents and how they became the people she experienced them as. Overarching the narrative is a meditation on parenthood, as it is the birth of her own child that inspires her to ask her parents more. They might have made major mistakes, but it is clear that they loved their children and did what they thought was best for them, making countless sacrifices to give them the best opportunities possible, even if that love was not always shown the way that they wanted and needed to feel it. Vietnamese perspectives on the war in their country were not something I was exposed to growing up (honestly the Vietnam War itself wasn’t something I remember being taught with particular rigor in high school apart from its connection to electoral politics), and I appreciated learning more about the history of the country and how the people who actually lived through the conflict thought about it. Even though this is not my preferred format, I think Bui uses it well to engage in some non-linear storytelling and to very literally illustrate what she’s trying to get it, like the way she parallels the way her relatively rural parents must have felt seeing Saigon for the first time with the way she felt when she first moved to New York, a sense of awe and possibility. It’s a powerful, moving work and I would recommend picking it up!
