I sure would! Rumor has it that gas engines don’t need to be “run in” these days but I believe that until you’ve put 30,000-50,000 miles on a new engine then it hasn’t been truly broken in. After that amount of time all the components have had a chance to run in and the engine is in the groove.

I change the oil in brand new gas engines when I hit 500-1000 miles. I like to make sure anything that is machining itself into actual running clearances has cleared out. This gets rid of any excessive wear metals in my oil. The first thousand miles I’m running the oil that came with the engine (usually conventional) and when I do my first oil change I use the real stuff, synthetic motor oil.

So after the piston rings have machined themselves to match the cylinder walls… lets get that oil out of there.

Is that how it has to be done? No, I think you can run synthetic motor oil from the get go but why waste the money? You’re going to dump the oil anyway so save the money and put the expensive synthetic oil in after the first change.

In my opinion mobil 1 synthetic oil is a superior synthetic because it is made with PAO basestock.  I really like mobil oil for this reason.  It has been around a long time and was almost first to market.  Though they did not pioneer the synthetic oil movement they do use PAO basestocks.

With modern engines and heat treat methods the engines are already run in from the factory anyway.  Just make sure you always keep your oil clean!
