The low fuel warning light now comes on after 245 miles. Before it was typically around 275 miles. This means there are 3+ gallons of fuel left in the car. I know the instrument readings are working, because I end up having to add 10 gallons of fuel when the light first comes on. Fuel tank is 13.2 gallons in volume.
I noticed this after switching back to conventional oil.
After using synthetic for 15,000 miles (3 changes after 5,000 miles), I decided to switch back to conventional oil, which I had been using for 40,000 miles. I switched back to con/dynoil, because the car was leaking twice as much with synoil, and there were oil spots below the engine, on the tarmac. This is likely due to deteriorating seals, and therefore switching to synoil was a big mistake as well as a waste of money, since I couldn't go 10,000 miles without having to add 4 quarts between each refill.
A check engine light came while I was driving home from work. Shorty before that, the car vibrated 15 seconds while it was idling at a traffic light.
I took it to a mechanic who said it was a 1399 error code. He cleared the code and said if it comes back on after 50 miles, the EGR would have to be cleaned up and a tune up would be necessary. The catalytic converter may need to be replaced if the EGR cleaning didn't work. I passed emissions testing last September. I notice gas fumes in the cabin sometimes. It's been over 200 miles now and light didn't come back on.
The fuel filter was replaced last year.(changed 20,000 miles ago).
Distributor, iridium spark plugs and cable (both changed 5000 miles ago), mid pipe exhaust, one of the engine bay gaskets (due to 2nd exhaust leak within a year), alternator, and PCV valve (less than 3,000 miles ago) were all replaced within the last 6 months.
I noticed better fuel economy when I changed the spark plugs, but this was only for 2 fill up cycles or so, and then back to 'normal' expectations.
