Any comments on AMSOIL's New Antifreeze?

[Lube Man]

AMSOIL just announced a new "breakthrough formulation" of a PG antifreeze that's good for 250K miles or seven years in passnger vehicles and trucks and 750K miles in over the road diesels. Anyone like to comment? Anyone talked to Cummins about this? At a dealer cost of $15. 25 concentrated this sounds like a really good deal.

$15. 25 dealer cost - so what's the cost to Joe Consumer?



I don't have anything against AMSOIL - except the price and multi-level marketing scheme they have going for their whole distribution chain.

$19. 95 retail. But why buy retail? Most people who buy any quantity, say $50 a year or more become preferred customers for $20 a year or $10 for half a year. Not any different than joining Costco.



Again, I'm looking for feedback on anyone who has spoken with Cummins.

I'm wondering how much different the new Amsoil PG anti-freeze/coolant is compared to their older stuff I have in my Ram and Honda generator?



BTW, I don't remember reading about this in any recent dealer mailing.

It's in the December 2004 AMSOIL Action News

I guess it's time for the antifreeze wars. Here are my comments:



The new Amsoil antifreeze is 2 to 3 times the cost of many other name brand products. It also has compounds in it designed to clog up leaks and who knows what else. It is a propylene glycol based product. Dodge reccomends using a ethylene glycol based antifreeze. I couldn't find anything on the Amsoil site on if the product meets Dodge or Cummins specifications or warrenty requirements.



Amsoil states the the antifreeze lasts 3 times longer (in miles) in heavy duty use than in light use. How do they do that?

Correction!

Dodge recommends using a ethylene glycol based antifreeze.

That is not quite true!



DC also does in fact recommend the use of PG based anti-freeze/coolant. The TSB dates all the way back to '97 if memory serves! And BTW, that would be CC back then.



Also, Cummins recommends the use of PG anti-freeze/coolant in both the 12v and 24v engines... and sells it as well (in two different forms no less).

Good responses. The concentrated price of the AMSOIL seems to be competitive with the FLEETGUARD. Question is whether it is as good or better. But why do they rate it 3 times furhter for the big rigs? What about the additive clogging question? Does it meet Cummins standards?



Yeah, lets get some healthy discussion going. That's how we all learn. And maybe this is a great product and maybe it isn't. Burying our head in the sand is not going to give the answers.

The Modesto Fleetguard dealer quoted me a price of $11. 92/gal for ES Compleat EG Antifreeze/Coolant in the premix.



The price for the concentrated was $8. 50/gal.



I told them to recheck as this did not make sense. The prices were correct and they agreed it made no sense to buy premix.



I then called AMSOIL tech dept and asked about the 250k vs 750K mileage discrepancy between small trucks and large trucks. Both carry the 7 year limitation. AMSOIL based the 750K figure on the added sump capacities of long haul trucks and special features on their cooling systems. Frankly I did not understand the answer.



Regarding meeting Cummins requirements they said that they will soon (within a week or so) be putting out technical data sheets showing the coolant meets all the ASTM standards required by Cummins.



Regarding possible plugging of orifices because of the stop leak additive they said this was not a problem since the additive was only meant for hairline leaks.



The product has undergone several years of development and intensive testing.



Now here is the really interesting comment. "The coolant can be used FULL STRENGTH". It is not critical to maintain the Cummins mandated 60% maximum concentration. Well, call AMSOIL for verification: 715-392-7101

One thing to remember if you're CHANGING from PG to EG or vice versa is that the two are not compatible. You MUST flush the old stuff WELL before you change. We flushed a generator of ours once with water (Cummins 4BT by the way!) and after an hour of run time there was sludge under the radiator cap. Three flushes and back to EG. This may be different in some applications, but if it says don't mix, BELIEVE IT!

Galen raises a good point. However, according to the AMSOIL literature this new coolant is "compatible with all ethylene and propylene antifreeze and coolant formulations on the market".

 

[CumminsAholic]

I may have to read the article again, but I believe that it said the amsoil coolant was compatible with any type of coolant on the market. . . Yep I looked at it again, From the Action News mailing . . "Compatible with all ethylene and propylene antifreeze and coolant formulations on the market, including DEXCool, Sierra, and Zerex. It is also compatible with fully formulated diesel antifreezes and other organic acid technology (OAT) and hybrid organic acid technology (HOAT) formulations. "

Makes it soooo much easier for SOME of us! You know, reading directions is for wimps! (until it costs A LOT to fix it... I read cover to cover anymore, and I even stop to ask directions if I'm REALLY lost)

What about http://evanscooling.com/index2.html looks pretty good.
