Why is my oil pressure low 07/25/2009
Often drivers will look at their oil pressure gauge and become concerned with readings that are below the halfway mark. ![]() oil pressure gauge I have often connected my trusted mechanical gauge and found oil pressure readings that were quite different than what the gauge was saying. If you are concerned with low oil pressure readings the first place to start is to find out exactly what the specifications are. Your auto service manual will provide oil pressure; specs for at idle, and also part throttle conditions. In some cases Diy car mechanics may be surprised that very low oil pressure is OK at idle by the manufacturer standard. Free Check Engine Light Diagnosis 06/20/2009
I wrote a page about free check engine light services and the problems associated with them. This brought on a question from a visitor that is going down the same road as many before him. You can see the discussion below. ![]() So I just read your article about free check engine light scams. I went to AutoZone they gave me the O2 sensor deal however they did recommend a friendly mechanic instead of selling me stuff. The reason I went wasn't because of the light though it was because my car was stalling out randomly. The mechanic offered me a free diagnosis just because we were from the same area of the country and he related to me. However he thought the problem was the engine temperature sensor and when he fixed it the problem stopped but then the check engine light came right back on. So I took it back and he said well I guess we can fix the o2 sensor and he did that but the light came back on again. Now during all this I already knew at the time that my catalytic converter was messed up but the person who inspects my car each year told me that I could get away without fixing it for awhile so I didn't fix it because before I met the "friendly mechanic" I got a quote somewhere else and the price was ridiculous.
