So I've had my Rav 4-1995 model for about two years now. There's this problem that's been there ever since I can remember and it really bugs me out. The fuel gauge goes down soooo low when I'm on a slope and returns up just a little bit when I'm on an uphill. Just now as I write this, the gauge was just above E and I went through a constant uphill for about 3 minutes and it went up to a 1/4. What's happening with my Rav? Is it a problem that's fixable? I'm I getting correct reading and therefore getting the most from my fuel? I have fully serviced it by the way so consumption wise, it's ok. But I'm just wondering where the fuel goes when the gauge goes down without going back up where it was. Help. Thanks!
