I recently had the wings removed from my CTSW for inspection. I'd told the guys doing the work that there would be 60-70L fuel in the tanks. They called me to let me know that when they drained it, it all went into two 20L cans and they estimated about 35L. I was very surprised as I never run it this low due to the issues discussed above, so took more fuel with me when I went to collect it. As soon as I saw the level in the sight tubes I knew that the dipstick reading would be higher than 35. Sure enough, the dipstick figures indicated a total of about 62L. I knew the sight tubes were unreliable, but I thought the dipstick readings were a bit more accurate than this. Anyone else found this?
