Just crank it up for crying out loud. It'll prime right up, build pressure and be fine!
I think the idea is to have those cranks occur under low-stress conditions. The amount of force exerted on a crankshaft bearing at, say 100 rpm is going to be a small fraction of stresses at 1,500 rpm. So theoretically the cranks occurring at starter motor speed will result in less wear until oil pressure builds than the same number of cranks when the engine is running.

Does this make a real-world difference: who knows? On the other hand, it's nice to listen to less start-up clatter.

Left and bought from Walmart. Next I took the filter off before draining the pan. Either there is always a lot of oil that spills out when removing the filter or that should be after draining. Lastly, the picture of the oil draining doesn't do justice to how far out it sprays at first, glad I had a mat down to catch it otherwise my driveway would have been a mess. Oh, also, I had to take the little brush guard thing off to get the cover off. Not sure how to do it otherwise.
As has been previously answered here, the S stands for Silicon ADBV. The silicon version is supposed to work better in the cold than the old rubber ones. Since the filter is located where it is, it doesnít really require any ADBV because the oil wonít drain back up into the engine. Iím still driving an 08 but may purchase a new Focus this summer. I currently have just over 140,000 miles my 08 and have changed the oil over 25 times on this one. I use the Motorcraft filter and the Motorcraft semi synthetic oil and have never had any problems. I use the same on my other 3 liter Ford which is now around 160,000 miles. Iíll probably be close to 180,000 miles when I get rid of my 08 Focus. The one thing that I do when I change the oil is poke a hole in the filter to keep down the mess when I unscrew it.

Certainly not a bad idea but I don't feel the benefit out weights the nuisance factor.
Consider yourself a very lucky man. Just think for a minute of the process that the lubrication system goes through, especially after an oil change. Before it lubricates anything in the engine it has to fill the element previous to supplying anywhere in the engine.

And THAT is oil change 101, precharge!!!

Of course by precharging the oil filter the first dose of oil your engine receives is unfiltered. I guess we all assume the oil coming out of a bottle is absolutely pure, but industrial things can go wrong (and are you really sure that bottle you bought was unopened?). Then there's that 1/4 quart of leftover oil that's been sitting on the shelf for a year that seems just right for precharging the filter...

Just did the 2nd oil change. Rotate tires and went through the entire under carriage with a keen eye. All looks good. Averaging about 3,000 miles per month. Car is doing what I bought it to do and doing it well.

Concerns: The key with these things is keeping them as far from dealerships as possible. I've found a dealer that I am willing to work with but man do you have to keep a close eye on them. Their mindset is doing things as quickly as possible and getting the next car in. Doing something "right" doesn't ever register on their meter. They are nice folks who have been sucked into a poor service mindset.

Comments: I doubt the pre-chargin hurts anything but modern motors are started for the first time EVER with a coating of manufacturing lube. The moment the motor is started, actually within about 5 seconds, for the first time the entire oil tract is coated in oil. During my career doing testing and development of high performance motorcycles I had the chance to be involved with the development of a new motor (Helicon) with Rotax in Austria. During testing the motor was run (we tried different oils), then the oil was drained, the motor was started without oil and run at redline for an hour to see what kind of wear we got. Bottom line is that the current crop (I use Amsoil, but they are all great) of lubricants, both synthetic and non-syunthetic, are absolutely amazing. Technology has really benefited lubricants.

It's nothing more than my PERSONAL OPINION but, absent something totally absurd (tossing in a handful or grit) you couldn't hurt a modern motor if you tried.

Milegae is great, handling is great, tires (with 15,000) look like they're due for replacement soon and the Focus is performing pretty much marvelously.

What a great idea ! I have always hated the mess when unscrewing the filter. What/how do you poke it?

Changed the oil with 1300 on the clock to get the break in oil out and it came out like water.

Thanks for the write up, made the job a breeze!
