    Question Break-in oil

    Would using something like Amsoil's SAE 30 Break in Oil or Royal Purple 11487 High Performance Engine Break-in Oil be useful in a Mirage's engine?

    I'm sot sure how the average owner would tell.

    I have read here on this forum that the Mirage comes from the factory with synthetic oil in the crank case. I'm guessing that is good for engine break-in as well as providing a slippery environment for the engine parts to generate the excellent gas mileage.

    Agreed. Plus, I'm not a fan of fuel/oil additives and the like.

    Synthetic oil has longer change cycles than traditional oil. 7500 seems about right, and cost effective for the owner.

    I was meaning as a break in oil. Most aftermarket engine builders will give you around a 500 mile interval for the first oil change. You know so you you get all the break in metal out of the oil and the oil filter. But i guess the newer engines are built with better spec so not so much metal in the oil.

    Severe-duty schedule (most American drivers?) shows 3750 miles for the first oil change though ...
