hi Jim. Thank you for your reply.

That's exactly what I thought, it's just the manual threw me off a little bit. I must say that I'm extremely happy with Syntec. My 12 year old Saturn doesn't show any signs of aging as far as the engine is concerned. I never had to do any valve or piston ring jobs on it. All seals are still original ones.

Thanks again, Jim.

No, it won't hurt.

The only thing that sometimes gets said about synth oil is that it causes leaks, which it patently doesn't. Synth oils typically have a detergent additive in them to remove the varnish and gunk that builds up. Basically, it only uncovers leaky gaskets in that instance.

Anyhow.. I'd use it in the Vibe without any problems. Synth oil generally gives you better wear performance, and if you live in areas that get frigid conditions, you'll love synths because they typicall freeze at a MUCH lower temp than regular or blends... also, the oil helps dissipate heat better in warmer climes.

The only thing that I'd say is go for a true synthetic oil like Mobil
