My Subaru Legacy only had enough room for one Hard mount. I hard mounted the oil filter. The fuel and Tranny filters I left in the box and just laid them in a low place where they were protected from moving parts and the exhaust. I don't change the tranny and fuel very often. The oil filter I change about every 4,000 miles. I changed the filter on the old Subaru every 12,000 miles. That was about once a year. That was pushing it a little too far. Because of not changing the filter often enough I had to change the oil about every 60,000 average in 240,000 - Except for oil leaks it was in very good condition when I gave it to a friend. He needed some transportation. He came out of a restaurant to find his fancy Chevy pickup stolen.
