臺灣知名論壇散播美國Prestone產品的不實謠言，美國Prestone公司在臺灣的總代理商｢運利有限公司｣代表美國Prestone公司澄清不實謠言，並附上美國Prestone公司技術中心Dr. Bo Yang的詳細說明，以保護Prestone公司和產品的聲譽。
 

美國Prestone公司的有機酸型冷卻防凍液在按照產品說明正確使用下，絕對不會造成車內系統腐蝕而洩漏的狀況。

若有發言者散播相關負面訊息，請提出實際的直接舉證。如果不能證明僅是因為使用Prestone的有機酸型冷卻防凍液而造成車內系統損壞，請務必將所有不實謠言下架，並且承諾未來將不會再散波不實謠言以損害Prestone的聲譽。
 

請見以下美國Prestone公司技術中心Dr. Bo Yang的澄清原文：

The Prestone DEX-COOL™ Extended Life Antifreeze/Coolant was developed as a universal OAT coolant suitable for use in all makes and all models of cars and light trucks, including both modern vehicles factory filled with other OAT/HOAT formulations and older vehicles that came from the factory with conventional silicated (IAT) coolants. 

While Prestone is aware of the on-line forums and discussions on the compatibility issues between 2-EH (i.e., 2-ethyl hexanoic acid, 2-EHA, or its alkali metal salts) and certain gasket materials, these issues are not present in our extensive real world product testing nor have we received complaints or claims from the tens of millions of Prestone customers that have used this product in liquid cooled gasoline and diesel engines on the road today.  Prestone has marketed DEX-COOL antifreeze coolant and similarly formulated coolant products, containing 2-EH, for aftermarket use in North America and around the world since 2000.
 

It should be noted that Prestone DEX-COOL™ Extended Life Antifreeze/Coolant (AF888/AF850) has been approved by General Motors as world-wide factory fill and service fill coolant since 2001 (under GM6277M/GMW3420 for DEX-COOL™ Extended Life Coolant).  Prestone Extended Life Antifreeze/Coolant technology with 2-EH has also been approved by Ford Motor Corporation as world-wide factory fill and service fill coolant (as Motorcraft® Orange Antifreeze Coolant) since 2010 model year. In addition, Prestone DEX-COOL coolant has also been approved for use as factory fill and service fill coolant for use in vehicles produced by SAAB, Opel, Navistar international Corporation (Truck OEM), Vauxhall, Asian vehicle OEMs such as Daewoo (since 2006), Suzuki, JMC (Jiangling Motors Corporation) , and GAC Motor, etc..

 
It should also be noted that factory fill coolants containing 2-EH (i.e., 2-ethyl hexanoic acid or its alkali metal salts) have been widely used in the US since 1995 model years. The 2-EH containing coolants have been used in Europe and around the world since 1975. In fact, Opel approved the use of G-48 (a 2-EH containing coolant) in its vehicles from 1975 to 2000 and Mercedes approved the use of G-48 in its vehicles from 1976 to 2014. The overwhelming majority of the aftermarket coolants for sale in the US and around the world today contain 2-EH.  In addition to GM and Ford, many global vehicle OEMs including VW, Mercedes Benz, BMW, Opel, Volvo, Bentley, Land Rover, Mini, Mitsubishi Carisma/Colt, Skoda, Smart, Tesla, and Truck OEMs such as CATERPILLAR, Freightliner, Volvo, Mercedes-Benz, MAN, and MACK currently use antifreeze/coolants containing 2EHA as factory and/or service fill coolants (e.g., coolants such as G-48, G-11, G-34, CAT EC-1, etc. marketed by BASF, Valvoline, Chevron/Texaco, Shell, Exxon, and other coolant vendors).  Since 2EHA containing coolants are in such wide-spread use, many vehicle OEMs have designed engine cooling systems so that they would be compatible with the use of engine coolants containing 2EHA even though their own approved coolants do not contain 2-EH (For example, Chrysler had design changes in their vehicle cooling systems to ensure their compatibility with 2-EH containing aftermarket coolants as reported by SAE in 2012).
 

In the U.S. and around the world today, OAT coolants account for the majority of the coolants in use in modern vehicles (Chrysler was the last NA OEM to switch its factory fill coolant from a low silicate HOAT coolant to an OAT coolant). Ford made the switch for the 2010 model year. GM changed to DEX-COOL™ for the 1995 model year). Many of the Japanese and Korean OEMs use OAT coolants containing a low level of phosphate for factory fill since around 2003 - 2005. European OEMs have specified Si-OAT (i.e., HOAT), or OAT coolants for use in their vehicles since the middle of 1970. In other areas of the world, automakers typically use coolant formulations selected by their US, European, Japanese or Korean joint-venture partners.

Given this significant world usage, industry certified testing, and history, it is a realistic conclusion that Prestone antifreeze/coolant is not only safe, but is also a preferable high quality choice for engine cooling.

Prestone DEX-COOL™長效冷卻防凍液是美國Prestone公司研發的通用型有機酸冷卻防凍液，適用於所有汽車廠家生產的所有車型的轎車和輕型貨車，包括在原廠添加了其他有機酸/混合有機酸配方的現代車輛以及在原廠添加了傳統無機酸冷卻防凍液的老款汽車。

Prestone知道該網路論壇上關於2-EH（即2-乙基己酸，2-EHA或其鹼金屬鹽）與某些墊片材料有相容性問題的討論，然而這些問題在我們大量的現實世界產品測試中並未發現，也未收到已使用這種冷卻防凍液在液體冷卻的汽油和柴油引擎上的數千萬Prestone客戶的投訴或索賠。自2000年以來，Prestone一直在北美和全球汽車後市場銷售含有2-EH的 DEX-COOL冷卻防凍液和類似配方的冷卻液產品。

值得注意的是，自2001年以來，Prestone DEX-COOL™長效水箱冷卻防凍液（AF888/AF850）一直被通用汽車公司批准為全球工廠原廠配套和原廠維修冷卻防凍液（根據GM6277M/GMW3420，適用於DEX-COOL™長效水箱冷卻液）。自2010年開始，含有2-EH的Prestone長效水箱冷卻防凍液也被福特汽車公司批准為全球工廠原廠配套和原廠維修冷卻液（如Motorcraft®橙色冷卻防凍液）。此外，Prestone DEX-COOL冷卻液還被批准用於SAAB、歐寶、Navistar國際公司（卡車OEM）、沃克斯豪爾，亞洲汽車如大宇（自2006年起） 、鈴木和江鈴汽車（江鈴汽車公司）及廣州汽車公司的原廠配套和原廠維修。

還應注意，含有2-EH（即2-乙基己酸或其鹼金屬鹽）的原廠配套冷卻液自1995年已在美國廣泛使用。自1975年以來，含有2-EH的冷卻液已在歐洲和世界各地使用。實際上，歐寶批准自1975年至2000年期間在其車輛上使用G-48（含有2-EH的冷卻液），並且賓士從1976年至2014年批准G-48使用在其車輛中。目前在美國和世界各地銷售的絕大多數汽車後市場冷卻液含有2EHA。除通用汽車和福特汽車外，目前還有許多全球汽車製造商，包括福斯、賓士、寶馬、歐寶、沃爾沃、賓利、路虎、MINI、三菱Carisma /柯爾特、斯柯達、smart、特斯拉和卡車OEM，如CATERPILLAR、Freightliner, 沃爾沃、賓士，MAN和MACK使用含有2-EH的冷卻防凍液作為原廠配套和原廠維修（例如由巴斯夫、Valvoline、雪佛龍/德士古、殼牌、埃克森和其他冷卻液供應商銷售的冷卻液如G-48、G-11、G-34、CAT EC-1等。）由於含有2EHA的冷卻液使用範圍如此廣泛，許多汽車製造商在設計引擎冷卻系統時已經考慮到與含有2-EH的引擎冷卻液的相容性，即使他們自己批准的冷卻液不含2-EH（例如：依據2012年SAE報告，克萊斯勒改變了車輛冷卻系統設計，以確保與含有2-EH的汽車後市場冷卻液的相容性。

在美國和當今世界，OAT冷卻液佔現代汽車使用的大部分冷卻液（克萊斯勒是自2013年以來將原廠配套冷卻液從低矽酸鹽HOAT冷卻液轉換為OAT冷卻液的最後一家車廠。福特自2010年開始轉換。通用汽車自1995年以來改為DEX-COOL™。）大約從2003年至2005年開始，許多日本和韓國汽車製造商開始使用含有低磷酸鹽的OAT冷卻液做原廠配套。自1970年代中期以來，歐洲汽車製造商指定Si-OAT（即HOAT）或OAT冷卻劑用於其車輛原廠配套。在世界其他地區，汽車製造商通常使用其在美國、歐洲或日本或韓國的合資夥伴所選擇的冷卻液配方。

鑒於在世界範圍的廣泛應用，行業內已經證明的測試和歷史，實事求是的結論是Prestone冷卻防凍液不僅是安全的而且是引擎冷卻更可取的高品質的選擇。
