I have a 2010 GMC Terrain SLE 2.4L w/Ecotec engine. I'm interested to see what sort of rate per 100% OLM others are getting since the software update.
Quick vheicle history. I had the fuel pump replaced in 2011 at around 42K. I did'nt really trust the OLM at that time and had gotton used to chaning oil around 5K. So I continued to do so with this car. It did'nt really matter however because the fuel diluting the oil for 20K or more miles caused enough damage to eventually require the engine to be replavce around 74K last October.
After the new engine was replaced I took it back to the dealer at 3K for an oil change. They reset the OLM at that time. The next change was in July at around 7K miles on the oil and 50% life still reading.
After reading a bit more about the OLM I wanted to test how accurate it works. I went full Synthetic Pennzoil Platinum and a K&N performance filter with that OC. I checked the oil at every fillup. Over the last three months clocked 12,294 miles on the sump and changed the oil with exactly 10% still reading on the OLM. That averages out to 137 miles per 1%
After I got to around 30% left I wanted to track the rate of OLM decrease with my driving patterns.
I use my car to and from work each day which is only a 12mi commute. I leave early and come home late so I'm usually always driving 55+. I also drive to job sites on an irregular basis. Sometimes 150-300 miles in one day. Again this is mostly highway speed driving. I am a fairly non-agressive driver and I usually keep the ECO setting on all of the time.
I had a period of heavy driving in August where I averaged about 230 mi per day 95% highway. The OLM was ticking down at 149 mi per 1%. Another period in mid September I did more city driving (which is rare for me) and the rate was as low as 72 mi per 1%.
I would appreciate if anyone else has tracked (or could quickly calculate) the average miles per 1% that they have experienced. I would like to compare and disucss those results.
I also sent a sample of this sump off to Blackstone for UOA. The new engine has 24,005 miles on it since replaced. I'll post those results once I get them back.
Looking forward to the discusion.
