Mobil 1.
Nostoc, I run Mobil 1 in every vehicle I own (8 at present time) and change it at 5,000 miles. Have had great luck thusfar. I've been buying Mobil 1 at WalMart for $19.82 for a 5 qt. jug. Just remember that your SSR needs one more qt. as it has a 6 qt. oil pan.
Brownhornet, The old advice not to run synthetic for several thousand miles no longer holds true. These new motors let the rings "set" much quicker. I drained my factory oil at 1,000 miles and went with synthetic. Corvettes, Porsches, Mercedes, and perhaps others, come directly from the factory with Mobil 1 in the crankcase. My Chevrolet Service Mgr. said he had heard that GM may start using Mobil 1 in most of their vehicles at the factory fill starting next yr. It costs maybe an extra $15 per oil change to use Mobil 1 over conventional dino oil but it's just a little extra protection, sort of like insurance. People who use it regularly speak highly of it and I've heard few, if any, negative comments.
