You know I thought that too until I really paid attention... The Prestone 50/50 stuff is $6+ at Autozone ($6.50 I think) while G-05 is $11.95 at Car Quest and each gallon makes two...
One of my snowmobiles was having strange overheating episodes, not actually overheating but getting quite high on the gauge, higher than I thought it should be. I decided to drain the overflow bottle (which is actually the top radiator tank on a snowmobile) and refill with G-05. The quart that lives in that tank is a significant portion of the coolant total. When I drained the tank I thought "geez that looks awful thick". I *think* what happened is that somebody ran straight green anti-freeze and its so thick that at low engine speeds it has a hard time getting through the thermostat. With a quart of 50/50 G-05 in the tank almost all of the heating issues are gone. I need to drain and replace the system totally at some point, maybe in the spring... -Curt Date: Fri, 12 Feb 2010 19:39:48 -0500 From: Tim C <bb...@crone.us> To: Mercedes Discussion List <mercedes@okiebenz.com> Subject: Re: [MBZ] Another e-Bay seller liar Message-ID: <e5fe3f3d1002121639s9399b50hce5739630d088...@mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 I have noticed that straight Zyrex is much thicker than regular antifreeze, but if it leaks you're out a lot more cash. -Tim _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
