No, I am not a frequent short tripper. Most of the short trips involve the ICE engine entirely off while the electric motor does the work. Sorry if my initial post might have insinuated otherwise. Initially, RAV4 Prime drivers note the ICE kicking in randomly. Then they learn what tends to cause it. I fear Prime drivers that do not learn to avoid the random ICE use, and adhere to 10k OCI are going to lose some engines.................
Yes, the RAV4 Prime has a learning curve in terms of how to keep it from kicking the ICE on randomly. But i mostly mastered that.
Frequent oil changes are NOT without impact. There is cost, hassle and environmental impact. All of which I consider.
I am following the oil discussion, but you guys seem to split hairs and bicker mostly!!!! Using a better oil in terms of avoiding damage from fuel contamination (of the oil, to make Rand happy) would be a good idea indeed. Doubt there is much objective data on that............
