Check your drain plug, also. I have a 93 T-bird LX that the oil gauge did the same thing. Come to find out that my drain plug worked its way loose somehow and it drained off slowly. The last time I had done an oil change, I didn't over- or under-tighten the drain plug. Come to find out I was 2 1/2 quarts down from a 5 quart capacity. I check my drain plug frequently now because of that. |
