Yeah, but it's 0W/20, not 30. I'd be more concerned with leaking $6/qt. oil than some possible gas savings when cold over the 5W/30. I tried the 0 before and where the leaks were acceptable with the 5W, the 0 leaked REALLY bad. Didn't notice any difference in gas mileage between the two, so I switched back to 5W/30 with that car and subsequent ones and can't say anything bad about it per my 250k tear down (because of a damn $12 valve). The 5W protected extremely well from New England winters to 100 mph+ in the summer desert, J-turns, high engine speed with low car speed sliding around in snow or dirt, and plenty of other high temp abuse.

Oh, wait I see you corrected the weights.
