In general, I would say "yes" if the ingredient concentrations and specs are the same. The auto industry does not screw around (too much!) and it doesn't matter if you are Valvoline or Bob's House of Coolants, you still have to put out a good product. The only instances I can assure you where...

Yeah, I just checked out our chemical flush solution and I can see how it could be mistaken for an "ammonia" smell. It's actually a good product to use, you just need to flush thoroughly because the flush solution will have a pH of about 2.5 and that's not very good for your system. Further, the...

This is true, but it really can vary greatly depending on the formulation. Concentrate blenders are supposed to actually use "demineralized" water, or soft water. The cost of maintaining a DI system for an enormous blender would probably be a bit much. The main thing you need to worry about, as...

Ammonia (NH3) just isn't going to happen in your coolant. I think your sniffer may be off a bit?

It's been my experience that the "cheaper" brands actually perform just as well (or better) as the "name" brands. The blenders they sell to require them to meet the same specifications and performance levels as the name brands.

I've seen brown coolant! Fresh, not used either.

Silicate precipitates can result from many things. Low pH is most typically the cause. Another, yet more improbable cause, is poor blending by the toll blender. (Toll blenders are the guys that cut the undiluted syrup with glycol) If a blender were trying to save money by leaving out a...

G-05 is also manufactured under other names if you can find it. I know the only place we've shipped syrup to thus far is California.

My guess is it is probably silicate precipitate.

Sounds like you actually should go with G-O5 to me. If you are running an aluminum block, then a low silicate formulation (like G-O5) will work better than an OAT formulation to protect against corrosion.

G-05 may also be called HCA-4 if you can find that. It is the exact same thing.

We have found that using recycled glycol is NOT a good thing. Recycled EG loses its pH and RA rather quickly. After making premixes out of the concentrates, we have seen recycled EG drop 1-2 pH units in a matter of weeks. As a result, you get less corrosion protection (as stated above), and your...

What you said was technically true. However, most people will not experience conditions where PG will hurt performance. I wouldn't recommend it for canadians or other very cold places, however if you live in some of the warmer regions of the world, there should be no problems. In fact, in south...

What does this "oily" substance look like? I ask this because sometimes I think that people confuse the defoamer with actual oil. It appears as a clear "slick" that will often float atop the fluid in small patches. So... the defoamer looks like an oil in the coolant.

Could have been many things to be honest. When the syrup was made, it might not have had the proper amount of silicate stabilizer in it or not been allowed enough time to couple before adding the next ingredient. The pH might have been too low. The glycol that was used may have been recycled...

That really nasty taste is either the bitrix that is added to the coolant or it is the benzotriazole. BT tastes absolutely terrible: We were having a problem with our mixer for our powder production and I went out to inspect it. They had a batch that had a large amount of BT in it. The mixer...

I can tell you that off the top of my head density of EG@60F = 1.116 g/ml density of PG@60F = 1.038 g/ml It's a pretty significant difference.

Ahh... ok. The hydrometers for conumer use are calibrated for the density of EG and not PG. Got it.

Ok... I honestly don't get what the heck people are talking about with PG and hydrometers. I read that article and had a few more knowledgable people read it and we collectively decided that it was a good little advertisement for selling refractometers. Anyone care to clear up the confusion...

I have a question about flushing: Since the corrosion inhibitors and other chemicals coat the piping, etc. inside of the coolant system, if you don't flush, does that make it more likely that you will overdose your system when you refill?
