I own an 1988 Honda/Acura Legend in Australia. the car has been siting in the driveway for most of the time. I haven't driven much, the last time I filled up was 2 months ago. I gave it a full tank, and now its I done 100 miles and its on a quarter tank, which is meant to be 60 litres. Something is wrong because people say that legends get alright economy. I changed the oil last week as well. Some symtoms the car has are a small oil leak from an unknown cause, and a tapping sound and spark like noise in the engine. It also has a big dent in the muffler. Any help on my problem would be much appreciated. Also would it be worth changing to gas as petrol is expense in Austraila.

I need some help here guys!!! I have a 1994 buick Century custom with a 6 cylinder, and as I was driving I noticed my temp gauge was starting to show on the hot side, never went into red, and the light never came on. I have owned this car for 5 years now and it has 85,000 miles on it. I have checked the hoses and clamps and I have not leaks anywhere. I drive this car back and forth to work, about 15 miles maybe so if there is a problem it maybe escelating now? Anyway, I am not mechanicaly smart but I cannot locate my thermostat housing I have read it is on the engine side where the upper radiator hose is at? The radiator has not been drained since I have had it so I thought it was time to change it anyway, but they say if you are going to do that then change the thermostat as well? It does not get hot on the highway, but does when I am stopping and going alot in traffic. I am just trying to catch something early before it does overheat on me. I also read that the heater has something to do with the radiator? I noteced the other day it took alot longer to warm up than usual and our weather in Gerogia is only in the 50's can you all help me first pinpoint what it might be, and then tell me where my thermostate is located so that I can do this right. thanks
