Engine decking issue(help)

...use a 0-x oil for good cold flow (even in Arizona) after break in
when cold" that's when most of your wear happens
when hot--oil not only lubricates it cools so flow is important
do not even think about 20-50 unless you are old school 2.5 to 3 or a race build
check your oil pressure

I never understood this. I have always run 20w-50 or straight 30 in anything from a 64 Barracuda to a 96 Neon to a 2001 Jeep Cherokee. Hundreds of thousands of street miles in FL, SD, MD, SC. Hardly any wear on any part and the motors run like new for ever. I also get better mpg than most people. Isky says not to run thin oil on flat tappet cams. I'm not buying the thin oil argument in the everyday street world. Just food for thought...
