Well I have been using Mobil 1 in my car since around 20,000 - 30,000 km and I am now at 293,000 KM and have never, touch wood, had any problems at all. I don't even burn oil.

I find all these posts funny (peculiar, not haha) because I asked a similiar question a few months ago and the answers then didn't say anything about synthetics accelerating an existing problem. My question was that with synthetic oil, I find that all 3 of my cars use oil. I check them each month and more often than not, I have to add oil, not alot, but enough to check. None of them leak, drip, puddle, smoke, etc. All the cars had 50K+ when I made the switch. I don't know if it's my butt dyno, but they all seem to run better now. I'll live with periodically adding oil, but I still don't have a concrete answer as to where the oil is actually going. Hopefully, there is not a problem in all 3 cars the oil is going to make happen sooner.

i guess because as said above the oil molecules are smaller a little bit of it is gettting burned off, just a guess dont know for sure, but i have heard that for the duratec's it is not uncommon for it to loose a little oil over a period of time, and that the engine is perfectly fine in it

Synthetic beats regular oil in every way. Will not go into the power or fuel mileage debate here, or even value for money, but it IS better oil.
Synthetic blend is basically just snake oil. Either use dino oil or synthetic.

I don't think anyone will argue it is superior oil. The argument is exactly where you said you won't go. Conventional oils will provide the same protection as Synthetic in 99.9999999999999999999999% of the applications it is used in and generally do it at a lower cost. Well, let's just say 99.9% to not exaggerate. If you want to spend more money on something that will have completely negligible results during a normal lifespan of a vehicle, then by all means do it. But don't do it because you feel you "need" to. My grandma driving 1/2 mile a day every couple of days probably has more of a need for synthetic than the most aggressive drivers on this site. I advised against switching to synthetics just because I find it difficult to justify the cost, not because of the potential leaking issue which leads me to my next quasi-rant

The argument about synthetics not causing oil leaks is technically true, but it's very semantical. I don't believe for a second that a major oil leak with conventionals was imminent with regard to the original poster. I'm sure there are cases where it will happen regardless of oil type. I belong to 15 car forums and have read countless threads about people switching to synthetics and finding oil leaks almost immediately. To think that each of the leaks would have happened almost immediately is foolish, in my opinion. Would they happen regardless of oil type in time? Of course, but it could also not show up as a significant problem for years.

I know some people who are pretty heavily involved in setting world and US oil standards who believe that Ford is treading on some semi-dangerous ground in order to acheive marginal increases in gas mileage.

I don't know about your leaking issues and what not but i used to use GTX 5-30 in my 1995 SHO with 131k on it. Car was a rocket! Switched to 5-30 Mobil one and the Engine almost instantly like 4 miles down the road started with a ticking noise. 24 miles later BLEW up.. Spun bearing cuased the #6 piston to stop rotating and in turn shattered the connecting rod. Could mobil one be the cuase sure i guess or it could have been that the Car would Rev to like 8300rpm everyday. Could be a wierd coincidence.

I used mobil one the whole life of My CSVT and noticed one difference.. GTX temp would be higher than with the Mobil 1.

Ok Tenzo 4 life!

Only time I have had a car with oil leaking problem was due to worn/torn rubber on the screw that holds the oil in. Replaced it and no more leakage.

I switched my SVT couple years ago and haven't seen any problems. Goes 5k miles without any noticeable drop in oil level.

gearhead,

I read your post, are you looking for my opinion on what I would recommend you run? Or is there something in there that I missed that may make me change my mind about 5w20?

No you just posted a link to a old post that stated Ford has deemed "said" engines to be able to run the CAFE/EPA improving 5W20.

Ford only picked 5W20 because it raised their average fleet MPG. This way they could sell more trucks and not have to make them actually run any more efficiently!

It is NOT because it makes the engines last longer. It actually causes a lot more long term wear on the engine to run with a much thinner, less protective oil.
Oil viscosity is a trade off between overall operating protection, parasitic drag, and start up flowability. (since most wear occurs at startup!)



Please get your facts straight because this thread is already chalked full with enough blatantly ignorant posts.
