Although this most recent OCI was the shortest of the three it was the most severe as can be seen from the OLM #. It began in cold winter weather and finished up...still in winter; lots of short trips and cold weather idling. I think this choice of Esso XD may well be as thin as possible and as thick as necessary i.e. the highly regarded M1 AFE 0W30 did not do as well and so I can right now conclude that this engine is best protected using a more robust (HDEO), thicker oil.
