interesting link.

sounds awesome i'll need to look into those.

OK Mr. I'm always right. If I came across as arrogant, I wasn't trying to be. I don't do pissing contests so you can take you almighty attitude elsewhere, since it seems you believe as a new user to this forum I don't have any mechanical knowledge to offer. If you noticed I agreed wih most of what you said I just questioned some of the info you gave. If you take every comment as a personal assault of you knowledge, you must be a miserable person and I feel for you. I have worked on many engines so I'm no dumbass posting useless crap, but more big blocks than small blocks so that is why i posted the question about other cars using full syn from the start and thank you for answering that, it's nice to learn something new. touche what! I notice he makes no retort to most of what i say except that he's a "Motorcraft Oil Expert", so I guess that makes him always right! As for the 1,000 mile oil change it's funny that you say it's not necessary when every "engine" mechanic I know says they always change the oil on a new car is to remove any contaminents that could cause striations and other problems in the engine, as I have seen the results of this first hand. I'm sure it's not as big an issue as in years past because of improved machining processes, but it's never bad to be safe. Keeping the car well maintained is the key thing here and just because your manual says or doesn't say so doesn't mean it should or shouldn't be done. Do you really think your cabin air filter needs to be changed every 15,000 miles, no it doesn't but our manual says it should be. To me that's just a money maker and nothing more. Same goes for 5W30 vs 5W20, either can be used and it will not void your warranty if you use 5W30, since Ford knows darn well why they use 5W20. I come to these forums to exchange knowledge not to be dictated how stupid I am and how smart you are! Just because we haven't been on this forum for a long time doesn't mean we don't have knowledge of autos. It's a community to exchange thoughts, ideas and information in order for us all to be more educated on the vehichle that we own so that we can make sure we get the most out of it, not to engage is who know more contests. So please in the future remember this posting replies.

All well and good, but why do cars such as cadillac and lexus all use only synthetic fom day 1, if it caused glazing, they wouldn't do that. 5W20 is just thinner oil than 5W30 which is actually used by both Ford & Honda to increase their EPA fuel economies by fractions of a mpg for a specific model, but those fractions allow them to not worry about bigger trucks and such having lower mpg's, since all that matters is the company's average mpg not each car/truck. The worst part about 5W20 is that the dealers buy from the lowest priced seller, which doesn't give me confidence in the quality of the oil. My cougar has 98,000 miles and still averages 32-35 mpg on the highway and I've used full synthetic Mobile 1 5W30 and Purolator filters from 1,500 miles on and have not yet had a single engine related issue. Just repalced gaskets for the intake manifolds 2,000 miles ago and was nearly clean as a whistle inside and my friends at 40,000 was coated in thick black residue. I would tend to think the ringing has more to do with the way the quick lube is performed than the oil itself. "Sucking" the oil from my engine does not make me feel good about getting my oil changed by a shop, which could cause problems until the seal are properly worn in. I prefer the standard drain (gravity) when performing my own changes. This isn't saying you aren't right about everything seating, but I'm not buying it all. In the end the important thing is if you have a warranty and they say get a 1,000 mile change, do it, then you won't have any problems if you ever need any work done under warranty. Also, as everyone has said before teach the computer your normal driving habits, but don't be stupid and constantly hammer it as you will most likely have problems in the future. P.S. Ford's 1,000 - 3,000 - 5,000 is a crock. My salesman just told me that 1,000 was the most important for the warranty and after that just stay on the schedule of 7,500, unless you're always towing then 5,000.
