Yeah they all have it and yes like stefan said it's hard to see due to undercoating.

regular gas line antifreeze is working and the car runs fine with it but I missed putting it in once and the problem was back so I add a bottle every fill .
I have also switched to gas with ethanol in it.

I have not had a problem with gas freeze-ups(or any other fuel related problem that I can think of) using ethanol blended gas, which has been about 20 years now. In Minnesota all gas has ethanol in it(at least all gas that you can legally put in modern cars anyway). Some gas stations carry non-ethanol blended premium, however you can't put it in modern cars. It can only be used in classic cars, boat motors, snowmobiles, etc. Ethanol is good!
