1992 Nissan Maxima from North America - Comments

My problem is that my car consumes 19 L per 100 km.

Please give me an advice.

The current car, 1992 Nissan Maxima, 3.0 L, 4 doors, was a good car until this January 2004 when the temperature gauge on the board stopped to work properly. Practically, almost all the time indicated very close to C - Cold engine. I went to a mechanic who changed the temperature termostat. After that the temperature indicator started to point middle level (as normal) between Cold and Hot, but in the same time the fuel consumption increased. Before this change, the car consumed 8.7 L per 100 Km on highway and 12 L in the city.

I took my car to Nissan dealer for a computer reading, but the Nissan's mechanic told me that he couldn't identify any problem?!?

I was surprised, but I noticed that the car is still consuming 19L per 100 Km.

It is a nice car and I would like to fix it, but I do not know how.

I would really appreciate your help. Please e-mail it at.

The car is very comfortable and accelerates very well.

One thing I suppose that has happened is that your oxygen sensor is damaged, so the engine does not work in a close loop. When your mechanic changed the thermostat, may be some antifreeze solution has fallen on the ox. sensor, so that now it is partially or totally clogged and cannot function properly. (i mean clogged externally of course).Go to an authorized mechanic to test your ox. sensor. consider about replacing it, if your mileage is above 100000 km.
