03 Silverado,do not use OLM. 03 Impala,do not use OLM. Both get oil changes Nov 1 with an 0w and May 1 with a 5w....
quote:Have you done any UOA to see whether your opinion of the OLM's performance is as insane as you think? Run a google or two and review the technical stuff written on the OLM. You'll find that it's calibrated to be conservative (set to call for a change earlier than necessary) while using the most average of dino oil. In addition, it's calibrated to the performance of each individual type of engine-car combination. If your's happens to be one that's easy on oil, the OLM's performance will reflect that. You might try this experiment to see for yourself: do a UOA on a sample of oil pulled out at the time when you would normally change it. As long as it's in good shape (I'm betting it will be), press on until the OLM signals for a change and do another UOA (no, I don't mean for you to do this on every change of oil...). The OLM in the 98 Regal GS I owned for a while was one of the things that got me moving away from the silly wastefuleness of the 3/3 OCI.
I dont use it because I have no way of knowing what % my oil life is at in my camaro. So, I do a 3k Oil change because I drive 6mi round trip each day to school and back, maybe Ill go on a 10-15mi jaunt if I get a chance. My oil life monitor tends to kick the light on around 5500-6000mi under these conditions which is insane! The range of my monitor is 3000-7500. So I really wonder what on earth I would need to do to make it come on sooner. In my opinon the light is a worst case scenario light.

wonder when the "oil industry" will move off the 3000 mile changes?
