Many thanks to all for the replies and input. With having nearly 50K KM's and over 30K miles, I guess there's not much point in trying to extend the OCI. Makes me wonder what the longest OCI is on BITOG. I'll book the Volt at the dealership for some fresh lube and filter.

Originally Posted By: Spector Sounds like you have not read the owner's manual? Son in law has one, I believe the manual on his states every two years, not sure if there is a mileage mark like two years and X miles whichever comes first. 30,00o miles on a 2014 is a lot of driving, hard to...

Hi. Looking for comments/input on when to drain the factory fill on my 2014 Chevrolet Volt that we purchased new in June 2014. The OLM is at 18% with 30,000 miles (48,500KM) on the odometer. Of those miles we have done 22,400 EV miles (36,000KM), or about 74% electric. I'll make it well into...

I have the GM 3.6DI (LLT) in my Outlook. It's had high iron as well. There was a timing chain issue with these engines for certain model years (VIN breaks apply). An OLM recalibration was also circulating for applicable VIN's. The OLM is far more aggressive now and has pretty much precluded me...

Originally Posted By: cp3 Hi BTV! Thanx for sharing! Looks good! Your best wear/km so far. I'm shooting for a 1 year OCI as well. Thanks. I'm really happy with how things are going with the Pursuit. Apparently I can now rate my stash level in years. By my math, I now have 4 years worth of PP...

Originally Posted By: dnewton3 The wear data shows that the longer OCIs are really paying off. Your wear continues to drop even as the OCI is extended. As for the TBN, I'd not worry. The TAN is the thing to watch; I don't know how much further you can go. I would think perhaps 12k miles would...

Originally Posted By: NateDN10 Oh, and I should add - thanks for posting this! I am always interested in Ecotec UOAs, and this one did very well. You're welcome. I share the same interest in seeing UOA's that are related to Ecotec. Furthermore I stand corrected, to that end thanks for pointing...

Originally Posted By: chubbs1 I think that 12k(mi.)/1 year is about the total limit I would push it. This is a great UOA, seems your engine is in great shape. If you could get ahold of PU I would definitely say 12-15k miles would be plausible in your case. I think that's about all I'd really...

Originally Posted By: hemitom Originally Posted By: cchase It's impossible, from this UOA, to say that the OLM is conservative since he was using an oil that has proven to be very long drain capable and the OLM is calibrated for a "baseline" conventional oil. I think it would help if we new at...

There are some short trips definitely. It's a mix of highway and city. Unfortunately I didn't get the opportunity to do a 'boil-off' run prior to draining. My preference would have been to give the car a good run up the highway and back before doing the drain. I seem to have fuel in both of my...

OLM hit zero on or just before Dec-02-2012 as my maintenance log has an entry for fuel on that date and I noted the OLM at that time. The OLM stayed there at zero for at least two weeks before I got annoyed and reset it. After that 'wrap-around' reset, the OLM went onto 65% which is when I did...

Hi. This UOA of PP (SM) is breaking new ground for me, a year long OCI with practically 10,000 miles. This for someone who was formerly on a 5000KM (3125 miles) regimen. This is a daily driver, mix of highway/city with a bias to highway. I've retained the old filter and will post some BITOG...
