I have covid and today's the last day to pick up my paxlovid from the pharmacy for it to have any effect, but my car has a flat tire. I've been trying for 3 days to get the lugnuts off, and I just can't get them unstuck. I'm using the shitty 8-inch tire iron that came with my car, and can't get enough leverage. I've tried jumping on it, I've tried beating it with a hammer, but they won't come off. And it's made even tougher by my diminished breathing and strength due to covid.
A small can of penetrating oil will help a lot. PB blaster is probably best and easiest to get. You can make your own with half ATF fluid and half acetone shaken up before applying. Also thermal cycling can break rust. Use a torch to briefly heat nut and let cool. Heating and penetrating oil several times usually breaks the hardest nuts free. Last if you can get a proper lug nut wrench it will make a big difference. These are worth their weight in gold you can get them at wally mart or horrible freight cheap or pay more from advance auto / autozone. Walmart usually has everything I mentioned here in stock.
