    Hey everybody,
    A few weeks ago I went to the Ford dealer for an oil change and ask if they had synthetic oil... They don't. But the technical advisor didn't recommend it to me for our car. He said that the gas doesn't mix with mineral oil and remains on surface. When we start the car, the fact that the synthetic oil doesn't mix with the gas would prematurely use the bearings. He told me that race cars do not use synthetic oil and if they do they change it every race.
    I don't know much about cars beside driving them, so please don't be too rude on me if it sounds stupid...
    He also told me that once you start putting in synthetic oil, you need to change oil at the same frequency as regular oil and if so, there shouldn't be problems (which is contradictory of his initial statement).
    Last thing, he told me that once you convert to synthetic oil, you can't go back to regular oil.
    So, what do you guys think?
    I know that many of you run on synthetic and haven't had any issues... but does what he is saying make any sense?
    Thank you again for your input, I need to do an oil change soon and am hesitating if it is worth it at all to go on the synthetic road. At least he told me that as long as the oil change are done regularly, the use of synthetic oil doesn't affect the warranty. So, there is no major risks other than spending money for nothing and not being able to go back to regular (that aspect is more for when I will sell the car, but it is in a few years anyway).
    Steve:thankyou:

    Synthetic is fine for your car. I ran it in my V8 SHO for years. I would think it would be what you should use.

    A lot of that info he told you is false.

    Synthetic is the only way to go. Been using in all my cars for the past 20yrs. There isn't one bit of truth in what you where told. And gas and oil do mix. I suggest you find a different dealer. They have to be the only dealer that doesn't offer a full synthetic oil change.

    Use the synthetic and don't look back. Been using it in my race motor for years and during a recent check of the motor I saw almost no wear on a 500+ HP small block Ford. Pretty damn good. If you have a LOT of time here is a great website: http://www.bobistheoilguy.com/

    Get ready to spend hours reading...

    I use it in all of my stuff. I change around 5-6k miles depending on conditions.

    They do offer it and it is the Motorcraft 5W20 full synthetic. I took an appointment for tomroow afternoon. SO, I have until then to see if I can find a better and cheaper oil. I would also like to use the 5W30 oil, but since on my oil cap it says 5W20, I don't want to have any issue if warranty needed... But I know the 2011 SHO is using the 5W30.
    Finally, I heard a lot of good about the Royal Purple (which I could get), so I am leaning on buying that one, but agsain, if they only have 5W30, I am hesitating... Could I use the Motorcraft this time and continue my searches and switch to a different full synthetic oil for next change?
    Thanks,

    Steve

    I use Mobil 1 5w-20 Full Synthetic. Wally World sells it in US for around $25. for the 5Qt container. I too wish I could run 5w-30 as my 2 G8's use that, and they take 8.8 Qts a time. Of course, if you own a Vette Gran Sport M-6 with the dry sump, it takes 11 Qts.

    I just sent an email to Ford Canada to ask if I could use 5W30 instead of the recommended 5W20 since they changed their recomemndation from 2010 to 2011 (other topic on that). I hope they can answer me back today... I could buy 5W30 Royal purple at my local speed shop for 9.90$/liter... we need 6 liters for oil change, so that would be 59.40$. I will have my oil changed at the dealer (just for the records if any problems) and they are going to charge me 25$ labor plus 6-7$ for the filter. So, that way I believe I would have better oil than the Motorcraft and the cost would be 91$ instead of the 119.95$ asked if I use their oil... The only thing is that my local dealer has the 5W30 in stock and would have to order the 5W20 and my appointment for oil change is tomorrow afternoon. I want the oil to be changed before leaving to my fishing trip with the gang (I will use my car and it is 400 miles of driving).
    I will let you know what their anser is...

    I wouldn't hesitate to switch up to 5w30. From what I was told about multi viscosity oils. They are both the same, there both 5 weight oils one has the characteristic of 20w and the other 30w but both flow like 5w oil. I use mobile 1 from walmart, with a motorcraft filter.

    that technical advisor is useless find another one however if you have a serious drug addiction he's probably the best guy to find the good stuff :rofl:

    nearly all race cars run synthetic and not all of them change after each race unless its some big sponsored outfit where each engine is worth almost as much as the car

    the SVT dealer here recommended me to use royal purple (which they stock at a really good price) its what i wanted to do asap when i got the car, and I have no regrets from switching over asap, i'm definately getting better gas mileage than regular motor oil

    if you have enough fuel going into the oil to cause bearing wear you probably have more problems to begin with, heavy blue smoke coming out the exhaust would be a good sign


    the only problem with royal purple is the colour is actually purple and can hinder as to how dirty the oil actually is (for the people that change oil based on colour)

    So, last question, can I switch from Royal Purple to Mobil1 to Motorcraft (considering they would all be the same 5W20 or 30)?
    Thanks a 1000 times!

    Absolutely. Some people even recommend switching up brands. There two things that are important about oil changes, 1 is that you change your oil when it's suppose to be. 2 that oil be API certified, this should never be a concern. Unless you buy your oil from a dollar store.

    I agree that that dealer mentioned above is smoking good stuff! Perhaps I should ask for some before my fishing trip lol! Did I just say that (replying to a Police officer!)?
    I only went there because it is 2 minutes from my home, but have decided recently to go back to the dealer that sold me the car in first hand (which I bought my last 4 cars!). When I called them back, he told me he had in stock... go figure! lol
    I will buy RP 5W30 as I am sure there won't be any issue since 2011 are running with it. BTW Mike, will you put 5W20 or 30?

    For those wanting to use a different weight oil, I'll say again, check out this website:
    http://www.bobistheoilguy.com/motor-oil-101/

    For those wishing to go to a 30wt oil, I'd say read this first. You may switch, but at least take a look at what this guy has to say.

    It is very interesting, but true that it is complex and very long to read... I would like to know for my use (daily driving it, but WOT many times every time I take my car) and drags about 6 times in 6 months and no drags from late October until April... From what I understand, the 30 is thicker, maybe a bit too much when colder temperature but i more appropriate when the engine gets very hot. So, my guess is that I'd be better with 30 during summer and 20 during winter, very cold, no drags, so engine will rarely get very hot.
    I receive an answer from Ford Canada and they basically wrote the portion of the 2010 owners' manual where it says to use 20... But at the end they say also that they are not technical and for that matter I should refer to the technicians at my dealer... As you read above, the tech advisor at my dealer is less than qualified... Ford Canada says that if there are not able to answer us, they, only them, can call a Ford division that would answer them directly...
    Anyways, I went to local speed shop and bought 6 qt of Royal Purple 5W30 and will have the oil change with it tomorrow. I will continue to read further and will adjust down the road, but will definitely stick with synthetic oil from now oon.
    Thanks all!
    Steve

    In short, you'd be better with the 5W20 all of the time. For road racing or sustained high temps MAYBE the 30 would help a bit. No harm in using the 30 in hotter weather, but I'd default to the 5W20 at the next change. It's not a big deal either way; you are using a good quality synthetic oil. Don't lose any sleep over it...

    I am using AMSOIL in my car

    The one thing when I drive on the highway I get close to 32 miles per gal

    This then I was driving a round trip about 120 miles, in all I do close to 24.5 miles per gal (only when I no not gun the gas) At all times I start off slow and place to cruise control at the speed limit.

    Steve, I've been using synthetic for almost 20 years and have never experienced any oil related problems. I had a 98 F-150 that I changed from 5W-30 to 5W-20 when Ford changed the oil recommendations and had no problem. I have used 5W-20 in all my Ford engines ever since. I would highly recommend staying with the 5W-20 recommendation, there has been enough miles put on vehicles that if there were problems they would have raised their head already. That said I just want to repeat that even though I use 5W-20 synthetic oil I still change oil and filter every 3000 miles. Just my two cents, and I have nothing scientific to back up my statements, other then I have seen a lot of miles put on vehicles I know personally and none of them have had any problem with the 5W-20 oil.

    THIS IS GETTING WAY TOO COMPLICATED....

    Almost makes me think I should just forget about the oil altogether.... LOL.

    Say... how much is a Nitrous system for the EB engine anyway???? Afterburners???

    Rocket propelled grenades?????

    Gotta be a way to get this brick into the 10's....

    I saw the engine oil refill for the manual equipped car -- that's just about double what my auto equipped GS needs.
    It says right on the filler cap to refill with Mobil 1 -- which just happens to be what I use in all my rides.

    The extra protection is worth every penny to me.

    Go for the full synthetic Steve.
