What type of engine oil do you use?
My 2006 has about 48,500 miles on her and I've been using 5W-20 like the user manual has recommended. Do any of you use anything different? And is it safe to start using a thicker oil once I hit a certain millage?

I am currently running Motorcraft Synthetic Blend 5W20. I got a pretty good deal on a case of Amsoil 5W20 so that will be next. I have a 2002 Ford F 150 that has 135,000 on it, and I run Motorcraft Synthetic Blend 5W20 in it with no problems at all.

Amsoil 0W20 full syn at 8k-10k mile changes w/Amsoil's Ea filter here but I've read that 5W30 is just fine in these engines. I may go to 5W30 Pennzoil Ultra since: 1) I don't put 8k-10k miles on the Stang within a year anymore (not my DD), 2) using 5W30 would standardize the oil that I use in my other 2 vehicles and 3) I have the Pennzoil Ultra sitting in the garage for the Stang or the SUV, whichever comes first.

I stick to OEM 5W-20 simply because of the VCT on these engines. They utilize oil pressure to adjust the timing . You start messing with the weight of oil you will affect the efficieny of the VCT system.
Cars that don't have this system I generally go to a 10W-30 or 10W-40 (during spring summer fall only of course) to help with the engine wear over time. I have no clue how the VCT system ages over time so I'd rather not guess.
