I'm new to gti's as a just got my 2005 1.8t and i'm about to change the oil for the first time. I went to the store meaning to buy 5w-30 or 5w-40 and got distracted by the sale price of the oil i just bought.... it's pennzoil full synthetic 10w-30. Is this oil ok for the 1.8t living in san...

can you guys help me out? i want an ecu chip for my '02 1.8t gti. my friend just turned me onto these things recently and i have no idea what to look for or where to start. any info would be helpful. thanks
