Yes, BITOG (BobIsTheOilGuy) is an excellent forum for all things automotive that have to deal with fuel and lubricants.

The best short answer is there is no perfect short answer. I saw one oil analysis of a late-model Honda that used the on-board oil-life-monitor system to let him know when he should change his oil. For those of us that regularly get UOAs done (I too use Blackstone Labs) we thought the oil had been pushed too far. It was not a catastrophic result, but what’s the sense in trying to save $10 per year by pushing oil changes out 20% too long?

If you live in an area of the country that is very moist, sees extremes of hot and cold and/or you make frequent short trips, it’s a good idea to change it a bit more frequently. The OLM takes some of these things into account … but then makes a judgement I don’t agree with.

Without UOAs, I’d use 6,000 miles for a “conventional” motor oil and 8,000 for a synthetic such as Mobil 1, Amsoil, Pennzoil Platinum, Castrol Syntec, etc …
