The Insight takes 0W20 oil. As I often do on my cars, I switch everything over to synthetic...engine oil, tranny, everything. However, nobody in Windsor carries 0W20...much less 0W20 synthetic. Ok..Honda carries 0W20. But I want something synthetic. I guess this means a trip to USA. I'm just wondering...how many cars take 0W20 and has anyone seen 0W20 oil in their travels through the auto parts store??
