I have been off the road for awhile, plus I'm dense as petrified wood. Chessmen say's FSC $1.15 8\20\19. How does this relate to a Transit type cargo van per mile?
If you want to treat your floor, there used to be a product used for Bowling alley Lanes called "Fabalon" (sp). When I worked for a custom home builder he used it on hard wood floors.
I have a little over 400,000 on F 250 super duty 7.3. Have run Mobil 1 since 100,000 miles. change the filter & add 2 quarts at 5000 miles then filter & full oil change next 5000 miles, along with fuel filter and air filter. So far nothing (knock on wood) has been done to engine.
For myself I cannot see how anyone after having a dog(s) then losing one or more could not get another. My parents got\had a dog when I was born, never been more then a few months with out at least one.
IF you lease a truck for say a year, why not install espar & build a bunk with partition in the van body. As long as you can open the overhead door from the inside.
I believe there's more then #1 company out there that will do an oil analysis. Call or E mail they send you a small container, send it back with $10.00 or so and they send you the results.
