you using conventional or synthetic oil in your truck? Ive been using synthetic in my grand prix now for about 3 years, i can get up to 5000 miles check the oil and its still at the same level as when i did the change and its still golden yellow color. I cant believe what that stuff does even at 5000 miles. I have 160,000 miles on here and still going strong as hell.. crazy

Just installed the Escalade instrument cluster (twice, MIL bulb was burned out, didnt notice till a code popped up P0650) .

Cleaned up cap and rotor, found 3 wires leaking spark (replacing tomorrow).

I got to install some 6.5" Hertz Energy components in the doors :) I also changed the oil and I put a quart of the Lucas oil additive shit in with it this time. Have any of you used it? It looks awesome

We use Lucas in our semi trucks at work...The cat engine in my semi always used a gallon of oil about every 5k since we started using Lucas it stays right on the full mark for the whole 8-10k between oil changes.
