For a few years now the automakers have been pushing 5w30 down our throats, and part of their selling point is that they say the 5w30 oil will flow faster and offer better cold start protection than good old 10w30. I believe this to be true in the cold wintertime, but is it honestly going to be any different in the warmer months? Have you guys seen any oil analysis data which proves that 5w30 provides better engine wear on the new cars compared to 10w30? I just feel that the 5w30 was brought out as a fuel economy oil only, much like 5w20 now too.
