Most articles seem to say that current synthetics won't degrade your seals. I would be curious to hear if there are people who have experienced leaks in the last 5 years that strongly correspond to switching to synthetic oil. Its also really useful when people include the temperatures that their vehicles operate when giving oil suggestions as this helps put the recommendation in perspective. My goal is to find a synthetic oil that is the best weight for Seattle (Summer highs of 90 and lows of 50 and winter highs of 55 and lows of 25) that also includes some sort of zinc content. Any suggestions? |
