Hello!! I would go with Mobil 1,FULL synthetic.It's been the oil of choice for the Corvette for quite a few years now.It's a little more costly,but I really believe it's worth it!!

 

I use Castrol, exclusively!

 

If you are doing everyday driving, use any good oil (Castrol, Pennzoil, etc) and change it and the filter every 3K miles and your engine will last. I hear all this stuff about synthetics and the fact they last for 6K+ miles and it sounds good---but is the additional cost and length between changes worth it????? Now if you are going to race the car, thats a completely different story. Synthetics might be worth the additional cost under those extreme conditions.

 

I USE MOBIL 1 FULL SYNTHETIC

 

Mobile 1 fill syn. I change it every 5,000 miles, makes it easier to keep track that way

 

My 2 cents: I use Mobil One and with 118,000 miles, no runs, drips, nor leaks.
