Topic: How often do you replace your fuel filter?
In the past we have changed the fuel filter between testing and the race in case it picked up some sludge from sitting.
I was just quoted $50 for a "napa gold" filter! I'm sure I can find one cheaper, but it made me wonder if it's pointless to keep changing the filter every race, which for us is once a year. I put stabil in the gas tank and ran it around the block a few times, but it still has the same gas from the track last year.
Do you think the stabil is good enough to prevent sludge formation, or would you still change the filter before the race, after doing some test laps to slosh everything around?
