bigdog said:Hey gblue- I was told that you can use a synthetic by my mechanic. However he said that you don't need too unless your engine is worth big bucks and you want the extra protection. My feeling is if you are changing your oil every 3000 miles it is not necessary to spend the extra money for synthetic.
Commo said:I'm considering using Mobil 1 in my Commander but I think I'll follow conventional wisdom and use dino oil for the first 10,000 miles or so -- there's some thought that engines want to break in a little more before using synthetic oil. Some even say that an engine might not ever break in properly if synthetic oil is used too soon; it's too slippery!
I _never_ know if any of this is true. One thing I wouldn't do is assume I can go far longer with synthetic oil than I can with dino oil. I'll still try to keep to the normal oil-change intervals.
