I have been bringing the jug inside at night to get house temp then outside during day probably should have brought it back in between funnel fill ups but I'm almost done now and gonna have to get another hug cuz it's not to the fill plug yet after 2 gallons added.

And do you mean if i set my wrench to 150 and double handle length it will click at 300 or I'm just suppose to know when to stop haha? Cuz I don't wanna strip my u bolts giving it all I got.
Should I just torque to my max torque I can do accurately then go around giving each of them 1-2extra turns then drive for a week and do all of them again 1-2 more turns? Then just check weekly for loosening and I guess after a couple months of them not loosening I can stop worrying haha. Changing u bolt s always makes me worry a bit after doing it but they always end up fine but I haven't had to crank any down with a higher torque spec then I can do accurately so I'm really gonna worry lol.
