okaythen nice so the engine runs smoother isn't my imagination...

ok so the manual says per oil change you should inspect the following: engine cooling system strength and hoses, exhaust system and heat shields, half-shaft boots, steering linkage, ball joins and suspension parts. lub if necessary.

engine cooling system you just look at the gauge inside right, if it's normal. hoses I am not even sure which hoses are those but just inspect hoses for any cracking, looseness, holes in the hoses. exhaust sytem and heat shields you gotta really get under it and look at it. most of the time they shoiuld be fine you don't really need to inspect those right?

Now I am not sure where those are: steering linkage, ball joints, suspension and tie rod ends, lub if necessary. But I am going to look it up but again most of the time they should be fine? they rarely go wrong and even if I don't know what they are just check under the hood and see if everything is normal like before, check for anything loose, anything unusual , etc? I am not really sure how to do those visual inspections.

If something is going wrong/bad and I didn't know since I didn't change oil at dealer and they didn't perform those per oil change visual inspections. Warranty should still cover it right? or engine cooling hoses, suspension parts what not.

block I agree - oil gets thinner due to the longer molecules breaking down. On my 99 Contour V6, I could hear the valves get slightly louder as the miles accumulated on each oil change.

Juicedz I'm looking forward to switching back to Mobil 1....unless penzoil wakes up and brings back the ultra. I don't care for their new full synth.

Elizabeth Years and years of doing my own oil change, and using Mobil One.

Yes the engine is definitely smoother right after an oil change.

okaythen Can you feel when it's new oil or different oil? or maybe it's just psychological effect lol. I feel the car runs better and smoother. (before I had syn blend from ford dealer, now I got mobil 1 full syn ) probably just happy that I did the work all by myself. thanks guys and girls for helping me with all my questions!

sailor Used isn't OK, even new that doesn't have the bad stuff in it can dry out your skin.

Old habits die hard though, I just try to keep clean & wash right away after getting any on me. Wipe clean/finish job/clean up.

No, it is not OK. Wear disposable vinyl gloves whenever you are working with used motor oil.

Not only will it keep a potentially carcinogenic substance off your skin, it will save you a lot of time trying to scrub the grime off your hands.

morrjr I've had two CELs in the past year, one on my 2011 Escape and the other on my 2013 Focus. Both were caused by problems in the emission control system, and both were evap system purge valve errors. My dealer replaced the valve in each vehicle under warranty, and that solved the problem.

sailor I obviously hit the wrong button when I replied to Marine, "I sometimes type too much" was the intended response....

It didn't make it to a post somehow.

The flashing CEL is a problem, you'd want to pull over & see if it went away or to a solid after a restart - then drive very short distance if it didn't.

Elizabeth covered it pretty well as usual for most CEL's that aren't making it run poorly, it also can light for a problem causing it to not run as well & those need quicker attention - sometimes not TOO fast depending on the problem. Getting it "read" so you can refer to info. on what it means is best for making a decision. Basic std. codes are even listed in the General Tech Chat stickies here. There's also a link to the full Ford discussion of how that works for each year in there when you need more info..

This year I had an intermittent involving the variable intake on mine, had to keep resetting the light as I looked it over since it took a while before the problem would STAY a problem when parked & running so I could trace it. Bad vacuum line was the end easy fix after a fair amount of figuring & checking - would have been VERY expensive to take it in for service while it was an intermittent to try & chase down.

It's nice to be able to take your time on occasion when the fault is minor & intermittent to aid in your diagnosis.
