I'm really not trying to spend $20 on a gallon of BMW Antifreeze/Coolant. Prestone claims that their extended life antifreeze/coolant will work in ANY car or light truck. Has anyone used Prestone over BMW brand, and if so, can you mix the two or should you flush and refill completely of one or the other?
Don't get me wrong, I'm a BMW enthusiast to the end...but c'mon...this is coolant we're talking about here...it's not like the BMW brand has magical properties. It's not like putting a different oil viscosity in or anything. Prestone should work for a little top-off, right?
I've spoken to enthusiasts, dealer guys and independent mechanics, and they all seem to agree on using only the BMW coolant (mixed 50/50 with distilled water). the $20 is well worth it considering it will last you a good 2 years (if you do a proper flush) and the potential problems it will prevent.
I am hoping someone will also explain the "why" of it, but IMHO The $12 premium you pay for the BMW coolant is worth it.
Buy the BMW coolant.
Don't believe the hype. I use peak 50/50, compatible with all types of antifreeze... green blue, gold. It's safe for aluminum blocks. Your engine wont explode or dissolve into a mass of bubbling aluminum...
Zerex G-05 is what I use and have been using for quite a while. Low phosphates is what you want for whatever you use.

That's what I thought. Like I said, I'm ALL ABOUT BMW authenticity, but for Pete's sake, this is ANTIFREEZE we're talking about here.
I actually went into my local BMW Store to get some damn BMW Antifreeze/Coolant tonight. I looked at the retail racks and they were filled with BMW fluids. They had fuel system cleaners, windshield fluid, brake fluid, etc. I'm sure all of this shit was the run-of-the-mill stuff, but with spiffy BMW labels and a marked up price. They even had quarts of engine oil...and were there Castrol labels on them? Nope. BMW labels! Now, does this mean that a Full Synthetic with a BMW label on it is better than the same viscosity of another brand? I bet not.
Anyhow, after this long-winded rant, I think it's bull-shit they hype up fluids. Sure, I agree that you should always use the proper specifications, but I think adhering to a brand name is redonculous.
I agree, antifreeze is antifreeze. All name brand antifreezes on the market today are of the low-phosphate variety. Some claim to have better rust inhibitors and water-pump lubricants than others, but I feel you can not go wrong with any name-brand product. Don't waste your money!
I know that a gallon of BMW coolant is only $10-$12 dollars more than, let's say, a gallon of Prestone, but it's the principal of the whole thing that pisses me off. I would be more sympathetic if the BMW brand was similar in price. I hate that they think they're entitled to more money because they took the same substance and printed their own little label to sell the shyte. But I guess that's capitalism for you, and I'm one of the sheep.
Yeah I agree, Plus you spend all that money and then turn around and have a simple coolant leak like I did (radiator temp sensor leak) and what do you know 20 bucks DOWN THE FRIGGIN DRAIN. It's all about merchandizing and selling other shit besides the car itself, everyone is trying to make money off the consumer.
I dunno about re-using old fluid. Unless it's fairly new, like only a few months in, I wouldn't bother re-using old fluids of any kind. Why not just use new fluids for peace of mind.
I'm not so keen on the "use-only-BMW-coolant" idea either, but IMHO, $20 for BMW coolant and another $2 for distilled water isn't much for peace of mind either. Under $25 to last two years before the next flush isn't a whole lotta $$$.
It's not just BMW that markets their own fluids, etc. Walk into any Ford or GM dealer and you'll see the same thing.....
I always use BMW fluids, unless I can upgrade some, such as Liquimolly
I have heard this said before and i quote ''i dont think bmw has some special plant in the german mountains where they manufacture their own antifreeze for their relatively unreliable cooling systems''
In general, I agree.
But, the post I was responding to implied that he had just replaced the coolant very recently, then had to drain it all out to fix the leaking temp sensor.
"I spent $20 on coolant four years ago and now I have to replace it AGAIN?? What a waste!" ha ha ha.
I've used Prestone in all of my cars with no problem.
i've used almost every brand under the sun of coolant...never had a problem. low phosphate to protect your aluminum bits and you'll be fine
I just switched to Prestone any make any model! Same thing!!!
Whatever you do, for god's sake do NOT use that Dex cool crap that I think is/was popular for GM vehicle.
Well the dex cool stuff is known to sludge up if it is exposed to air like from a hairline crack, or even just opening the cap and leaving air in the system, and turns into a nightmare trying to flush that shit out.
The Prestone brand you guys are referring to is the 50/50 premixed one correct? yellow colored bottle I believe?
note - I'm new here. Trying to learn some things since I was never all that great with cars.
