[V8] Oil Weight

[Scott Simmons]

I've never ever heard any substantial/proven evidence against switching 
to synthetic, only old-wives tales.  Some say "well it makes dino-oil 
seals leak" but most of the time those seals are leaking anyway.  
Synthetics have come a long way since they were first introduced and a 
lot of the sludge/build-up problems are long gone.  I'm going to be 
doing an oil change here soon, as well as a starter change, and will be 
putting in M1 0W40 because I loved how well it's worked in my other 
vehicles.  It acts just like a 10W40 (or a 15W40) at most temperatures 
but when it's below zero, it's thinner, flows easier, and warms up faster.
