I finally got a new motor for my mazda 626, which had bad valve guide seals in it. I just did an oil change and used NAPAs 5W-20 oil. I am currently in Northern Minnesota where it gets as cold as -35 F on some days. As mentioned I just got doing an oil change and am interested in running at least 2 cycles of Auto -RX through to ensure the longevity and good running of my engine.
My question is that - as cold as it gets up here is it ok to add stuff in to the oil? Is this product designed to be used at temperatures as low as -30 F or will it freeze up again in the motor?
I would probably wait till at least July when the ice finally melts off the lakes up there. (just kidding)
I'm a bit confused. You say you have a new motor? Why would you need to do 2cycles if the motor is new? Did they just replace the heads or just replace the valve guides? Or did they put in a used motor? If it's a new motor you could probably just do maintenance doses. If it's just valve guides, heads or a used motor and you have over 100,000 miles on the motor you probably should do 2 cycles. Probably for clean and rinse cycles I would think that waiting till April when temps are warmer would probably be best.
Thanks for the reply. The motor is a used motor - but new to me :). Motor only has 80K miles on it, or so the junkyard man claims - so I thought it would be better to run 2 cycles through it.
I was also thinking of driving down to Michigan and putting some serious miles on the car and hence wanted to start the Auto-rx cycle as soon as possible. Guess it's best to wait till it warms a little bit in a few months
I have only put 10 miles on the car since the oil change - on Friday. I don't think I will be driving till Tuesday morning and could definitely put the Auto RX in it before I drive then. However the temperatures are going to be as low as -11F and the highs are about 3F for the middle of next week!!
Wondering what Frank Miller would have to say about the use of the product at these temperatures. Still a little worried about the way the product behaves in sub zero temperatures...
The product behaves the same way your oil does. Follow the instructions regarding pouring Auto-Rx into your oil ( these instructions are on the home page the FAQ please read them ) if your concerned your oil won't hold up in the temperatures you describe than you have to make a decision about changing the oil.
Auto-Rx once in the oil reserve takes on the characteristics of your host oil.
Auto-Rx does NOT change viscosity, oil chemistry it is a cleaner not an oil additive.
Please reread the web site it is full of factual information.
