I have just purchased a 2006 Electra with only 50 miles on it. The dealership has used Synthetic 20/50 oil in the engine before delivery. I drove home from the dealership with this oil for about 50 miles at a speed of about 60-65 mph. When I reached home, I read some information from Peter Snidal and the owners manual, which said that synthetic oil should not be used in Bullets. My dealer said it is fine to use synthetic oil with bullets. I changed the synthetic oil with regular 20/50 oil based on the recommendations from Pete Snidal and owners manual. Now, yesterday when I drove it for about 20 minutes at the speed of 60 mph on the freeway, looks like engine got overheated and blue smoke come out from the exhaust. So, first of all, should I use synthetic oil in my bullet or reglar mineral oil. Can regular oil sustain the heat from driving at that speed? Have I sustained any damage due to this blue smoke?
Any help would be appreciated.
