Ok guys so my sc300 is wasting a lot of gas. I dont know the average mpg but I'm only getting around 250 to 300 miles from my tank. What is an inexpensive thing I can do to get better gas mileage? Or something that isn't so pricy?

how many miles do you have? you could have a bad O2 sensor... if one or both goes bad you will waste a ton of fuel... i had the same thing happen on my supra... i had a bad O2 sensor and was only getting 200 MPT when i would usually get around 300 MPT

Ive been having this same problem. I would be lucky if i got 280 per tank. Idk if its because i have an exhaust leak or what or if i need a tune up or something. maybe new spark plugs??

I changed one o2 sensor and it was on the exhaust manifold for cylinders 1-3. I haven't changed the other ones. Could that be the problem and the check engine light did come for that one. Should I change the 02 sensor for 4-6 on the exhaust manifold or the rest of them on the car? Oh and the car has 192,800 miles.
