CASTROL EDGE with SYNTEC
You can use Castrol Edge Full Synthetic ( I will at the first oil change)- The tight engine tolerances of the Spark need 5-20 oil and The tires came with 40 pounds , Many people are saying put in 32 BUT the frame on the front door has the tire specks and specifically reads 40 Pounds air pressure ALL tires. Less than recommended is only going to make the tire wear uneven and give you poorer mileage???
I love my New Lemonade LS 2013 model with the 5 speed stick shift its a BLAST to drive compared to the Sport Trac I traded in!!!
