What weight oil are you running and why?

I use Chevron 5W-30. Back in 2002, I sent an email to a Chevron Oil Co. engineer and asked him which Chevron oil met Ford spec. WSS-M2C153-H for the 2001 F150 I had. He replied that both Chevron 5W-20 & 5W-30 met the spec. (I still have the email on file after all these years)
If you dig back into the archives you may still find a TSB from Ford from back in 2001. I saved some of the text from that TSB.
TSB 01-4-7 actually mentions the reason 5w-20 in now recommended:
"ISSUE:
Engine oil recommended for use in 2001 vehicles is SAE 5W-20 motor oil. This oil has an improved formulation to improve fuel economy."
If you go back even further, to TSB 99-8-16, they recommended switching from 10W-30 to 5W-30. Tests have proven SAE 5W-30 viscosity grade motor oil provides the optimum protection and benefits for Ford gasoline engines. At both high and low ambient temperature conditions, SAE 5W-30 provides the best overall protection. It allows faster starts under cold ambient temperatures.
SAE 5W-30 also provides approximately 1/2% increase in fuel economy over SAE 10W-30.
It looks like the real reason for the change from 10W-30 to 5W-30 to 5W-20 is to gain a very small increase in fuel economy which allows the manufacturers to claim a tiny fraction increase in the CAFE.
So....I know I am going to get flamed for posting up 10 yr old info. I can only hang my hat on what the Chevron engineer said, what is in the TSB's, and the fact that I've always used a different weight oil than what the owners manuals call since owning my very first vehicle in 1972 and have never had an engine failure.
I'm sorta stuck with Chevron 5W-30 whether it is good or bad cuz I have 17 cases stored up and Costco has it on sale this month for $9.00 a case off, so I suspect my stock pile will get larger with my next trip into the city.
