![]() I know of the biggest offender being mixing green and Dexcool (red/orange), but I wonder if there's anything else I should look for if I ever mix any antifreeze. I wonder how much this will affect my car in the long run.Īnother question is if it's ever good to mix the antifreeze, given the ingredients are the same. much coolant in the system, then the compressor will have to work extra hard to move this coolant. However as seen in point 3 and 4, each of these antifreeze has their own extra ingredients. 5 oz - BK 7653507 online from NAPA Auto Parts Stores. I can't see spending 50 for 2 gallons of 50/50 colant. I need 2 gallons, so I'm going with the Zerex at 13 a gallon, half the price of the Toyota. ![]() The alternative antifreeze all have a Proprietary corrosion inhibitor agent, and some extra ingredients unique to each antifreeze.įrom that statement, it seems like these antifreeze are all appropriate purchase (with PEAK's potentially eliminated given it's designed for POAT). The Toyota dealers here want 26 for a gallon of of the Toyota pink SLL (Super Long Life) coolant, which as mentioned by Sayjac only comes in a 50/50 pre-mix. Toyota's Super Long Life Antifreeze has the following ingredients the rest do not have: Sebacic acid and potassium hydroxide. With the exception of PEAK's Coolant (which seems to be targetted at POAT coolant) the rest of them either use or are compatible with HOAT (hybrid organic acid technology). I'll list four examples, the first being the OEM Toyota antifreeze, and the rest being alternatives:Ī few things I can say after looking at them:Īll of them have ethylene glycol and diethylene glycol. I could just buy the OEM antifreeze in the local Toyota dealer, but I also want to know if I ever use an alternative, how would I be able to tell they fit. The car's owner manual say, " Only use Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology." So when it comes to my car, which originally came with a red-like antifreeze, I need some assistance identifying what is the correct antifreeze to buy. Apparently this was not true and that the ingredients matter more. I always thought when it come to buying antifreeze, as long as the color is the same it would be fine.
