Effects of the Wrong Oil?

[dagosa]

All motor oils are pretty darn good and their differences lie in there ability to handle extreme conditions of heat, cold and long change intervals, not normal driving conditions. This is especially true of organic vs synthetic oils. You have done NOTHING to harm your car. Your car will turn over more easily in cold weather with 0-20 synthetic oil on start up. Some increase wear over the life of the car will occur if you don’t use it for it’s lifetime. Nothing measurable in one oil change. I might do the oil change a little earlier before too cold weather sets in. That would be he ONLY reason I would worry…slightly.
