I have a brand new shed I built for my wife. Brand new lumber no bugs. Every spring since I built it, the birds have come and drilled holes in the siding. The only bugs that have ever been in it are the bees that fly in the holes the birds dig. I use a pump pellet rifle with a scope.
That is correct for some models. I made my own dipstick from a parts car. Filled the oil levels, trans and engine to specs cold, made a mark, then ran it hot and made another mark. One side for eng oil and the other for tranny.
