The packaging must say hot-dipped galvanized. Hot-dipped galvanized nails not used in a nail gun often have clumps of zinc on the shaft or sometimes have an uneven coating of zinc. Other methods of galvanizing leave a much smoother appearance on the nail surfaces than hot dipping.I use hot-dipped nails because I want no rusting.he best nails are dipped a second time in the molten-zinc bath. There are other processes for galvanizing nails, but they donât offer the level of protection that hot dipping does. Years ago, it was impossible to locate hot-dipped galvanized nails that would be compatible with nail guns.
Costs. High mileage motor oil is considerably more costly than regular oil, but the benefits to your engine can be worth it. It is always a matter of personal choice as to whether you decide to continue using high mileage oil.
A local oil change recently wanted to charge $80+ for an oil change using synthetic motor oil(Valvoline)I did not do this as I was prepared to pay $19.95 qat this location as I did on my 2006 Prius.I had them use 5w20 as previous.They also stated that the oil needed to be changed at 4000 miles,whether regular or synthetic oil was used.
