At which time all kinds of alarms should be going off such as low oil pressure often accompanied by overheating etc. OTOH, old worn out oil can be hard on bearing surfaces. I had a failure on a V6 cam, (right after the second lobe), after a run of 10K between oil changes including a few "check engine" lights. Car had 160K on it and it failed suddenly and took about a month of tryin' this 'n that before finally pulling the intake manifold which revealed the ugly truth. Thankfully, the rearmost bearing was ok but the others not so good but in a position to replace without pulling the engine. Now, I'm pretty fastidious with regard to oil changes... Usually about 5K with dino oils. JT |

It makes me feel better. dude, with respect, that's crazy. a quality synthetic is formulated to let you run long. the conditions to be met include: 1. base oil doesn't break down 2. additives don't break down 3. other additives cope with the chemistry conventional oil bases do break down, their additives break down, and because of the first two, they also have a correspondingly lowered ability to cope with chemical load like acids. given that #'s 1 & 2 are easy for synthetics to achieve, #3 is the one to look for, and it's /loaded/ so it can go way beyond your 3k. discoloration of the oil doesn't mean a damned thing since the filter ensures particles are below the wear threshold. my buddy who works for exxon-mobil has a chevy tahoe. the fall-back factory service interval on that is 3k. using the analysis resources he has available, he has the service interval pushed out to 25k. again, that's a 25,000 mile oil change interval based on analysis. conclusion: 3k on synthetic is crazy. |

My old '76 Coronet burned a quart between gas fillups.

Make a hard right turn, and if you smelled gas, you had some left (never could put in more then 5 or 6 gallons at a time)! Not sure what was worse with that one, the hole in the tank, or the brakes that needed to be pumped a dozen times before I could slow down...... |

I don't think I ever > "changed the oil" in the traditional way the whole time I had the car. Worse car for oil consumption for me was a $50 Torino that achieved a whoppin' 50 miles per quart. Then came a '76 Civic that average between 1-2K per quart. Of course, that car cost me $500! JT |
