Hello,

I just purchased a new 2018 Chevy Spark 1LT! I heard that the first oil change should take place between the 1000-1500 mile mark, to flush out any new engine shavings. My questions are:

1) Is that too soon to change the oil?
2) Does the 2018 Spark come filled with synthetic or semi-synthetic oil? The dealer said it was semi-synthetic.

(The new 2018 calls for OW-20 oil - not the 5W-20. I plan to use Mobil 1 OW-20 with Dexos.)

With 152 miles showing on the odometer, I decided to fill-up with 87 octane at Costco, a Top-tier fuel, with 10% or less ethanol added. I did the math and calculated 40 mpg. I'm a fairly modest driver, though I am meticulously varying engine speeds to break it in.

3) Will the Spark benefit - cleaner engine, better fuel mileage, etc. - by using premium fuel? Or is it a sheer waste of money?

Thanks!

DJ

I have always changed my oil and filter prematurely the first time. It's cheap insurance. As for the fuel, in my experience, mid grade gives you better mileage and the cleaners and additional octane are beneficial. The higher grade 'premium' has additional octane that, in my opinion isn't worth the additional cost
