atta boy justus, i only run synthetics in my vehicles too.. Amsoil, good stuff.. I'm currently building the new BG products facility in El Dorado KS. they make a damn good product as well, dont think they make oil though, Lucas is good stuff too!!

 

Mobil 1 for me, all the way!

 

I don't think brand matters all that much, however, for turbo applications, synthetic has always handled the higher temperatures much better. Just keep it clean and change it when it needs it

 

Royal Purple!

 

Royal Purple is pretty good as well.....check out AMSOIL when you get a moment

 

I've always been confused by the weight of synthetic oils. I typically use plain ole 5W30. I've never shopped for synthetic oils before. Do you use the same weight? I seem to recall only seeing 10W40 in synthetic when shopping at walmart. I assume 10W40 is for diesels. Am I correct. Do they make a 5W30 in full synthtic?

 

i'm sure they do!! try autozone in liew of wallyworld,prob getting crappy chinese oil there!! lol

 

10W-40 is not only for diesels, it’s often for motorcycles too, given it's ok for wet clutches, But I’ll try to keep on track here. If an engine recommends 5w-30 then that's 5w-30 for synthetic or dino oil. Synthetic oils just have better heat transfer properties and do not break down in the same way dino oil does. While we are talking about oils, 5w-30 is a multi-weight oil, unlike say, plain SAE 30 weight oil. Multi-weight oil uses polymers which allow the oil to be specific weights at certain temperatures. SAE 30 as well as 5W-30 and 10W-30, and so forth, 30 being the common factor here, will all have the same viscosity, or thickness, at operating temperature (around 210degF). The difference is in the Winter number. The 5 in 5w-30 means it acts like a 5 weight oil during cold temperatures, like in the winter, which is what the W stands for. The lower the viscosity, the thinner the oil and the less resistance to oil flow you will have. That’s why thinner oil is better for colder climates, you get faster oil flow during cold starts. That’s also why you may hear people recommending 5w-30 over 10w-30 in the winter time. Now, you may ask why is the oil a 5 weight at cold temperatures and a 30 weight when hot? Shouldn’t it be thinner when hot? Well there is a different scale for grading Winter viscosities than there is for rating SAE viscosities, which makes the numbers seem confusing if you are trying to compare them. Hope this helps, it’s a bit confusing at first, but it sticks.

 

Thanks for the explanation for those not familiar with the properties of multi-weight oils.

 

Never messed with syns in my vehicles but with my bikes I have tried Mobil 1, Amsoil, Bel-Ray and Redline. All had similar results but I have a preference to Redline and Bel-Ray. Though Bel-Ray is powersport specific so disregard that one. :wink: May give Redline a try in the Focus just for grins and giggles.

 

I remember reading that redline oil has zinc in it which isn't good for the cats. Put it in the gt500 and it ruined them. Unless redline has one that doesn't have zinc in it.

 

I will be using a Full Synthetic to help reduce the chance of coking form dino oil cooking in the turbos bearings.
And you always what to let the car idle for a little while after hard driving to let the turbo cool down some before shutting it off.

So I will be using Mobil 1 as it is easy to find and sometimes even on sale!:money:

Steve

 

yeah really,good advice, had no idea about letting the turbo cool down!!

 

Thanks a lot. Thats the best explanation I have ever seen on the subject!!

 

Here we go again... every auto blog has a discusion of oil. First thing first.... it is your car. Use the oil you want. Opinions are like belly buttons Everyone has one. Synthetic (unless recomended by Ford for the ST) is overkill unless you do serious racing all the time. In other words MOST of us will be driving to work having a little fun now and then. Using Ford recommended oil and filter changed when required will last just as long as synthetic use. As far as the turbo and coking go.... I doubt there will be any problems. The turbo is water cooled I do believe. And current oil technology makes coking very unlikely.

 

Haha. Yeah I know what you mean about oil threads. I am on a few auto and MC forums and they never end on a good note.

 

Agree with above.

I have used motorcraft synthetic in my mustang most of the time because that's what ford uses. I did use royal purple for a couple changes but the price is stupid, $7 a quart compared to $15 for 6 quarts of motorcraft

 

So when are most of you guys planning on changing the oil for the first time? I know it's probably not needed but I'm planning on changing mine at 1000 miles.

 

I'm hoping to be changing oil sometime soon, but not optimistic. Last week my dealer told me the car was going to be built yesterday, the etis web site says 11/30! I'm thinking definitely within the first 1000 to 1500 miles. Want to get the break-in oil out and some synthetic in.

 

I wouldn't trust that etis website. It had my VIN being built next year when it was built Aug. 30th.

 

Throw some AMSOIL in there after STdan. That stuff is awesome!

 

STDan, you'll have to let us know how the ST is for driveway oil changes!! Some vehicles can be a pain!. Chevy put the oil filter directly above the frame rail on my Colorado. You have to leave the drain pan under it for hours before it stops dripping.

 

I'll probably just take it to the dealership to have the oil changed. It gives me a good excuse to go cruise the dealer parking lot and look at new cars

 

My dealership said to wait 5000k miles. I was looking at the filter, which is in the front of the engine, but it didn't look easily accessible. For sure you'll have to remove the plastic under cover to get to it, but not accessible from above.

 

Ford reccomends Motor Craft Oil, Its a semi synthetic which i will not attempt to explain what that exactly means. Ford says you can go up to 10000 miles between changes in all the new eco boost's, but I dont support this. I think if you asked 10 different people you would get 10 different answers. I'll be sticking with what the factory uses and reccomends.

 

Full Synthetic, Blend or Conventional Oil?

Amsoil

 

Got my Tuxedo Black ST today, and looked under the car..... anyone changed their oil yet? Is that stuff under the engine easy to take off and put back on? I always change my own oil, but this looks like a pain every couple of months....

Mobil 1, save a bundle, buy it at Costco!

 

Yes, I did change my oil @1200 miles with the RECOMMENDED FULL SYNTHETIC Motorcraft 5w30 and a Motorcraft filter. Wish it were a cartridge. Anyway, the underpan comes off easily with a torx bit. You're all gonna have your opinions, but after running it hard on the track for two days I felt it was time to ditch the original stuff and replace it to get rid of the bits that were in the filter or hovering in the oil.

While oils today really do last I will not buy into the 10,000 mile interval. I believe it's all how you drive. You sit in traffic then you might consider more frequent changes. You drive on the highway then not so frequent. You drive on the track then you might conisder after ever other event depending on the time of year and location.

What I won't do is put heavier oil in cause cold startups will probably bury the oil psi gauge and cause some other unknown issue in the long run.This engine doesn't suffer oil pressure problems, but with a small turbo like this it generates a lot of heat which will break down the oil. Otherwise have fun putting in whatever you want. Although, I wouldn't put dino oil in any turbo car.

 

Just got my Tux-Black ST today, and looked underneath. Looks like a pain...... if you have changed oil, please post how easy it is to take the covers on and off.
Thanks

 

You guys should read the manual on break in procedure and first oil change and all that before you do something stupid

 

Pennzoil Platinum or Ultra
Rotella T6

 

ETA...9/19-9/22. They can't seem to get together on it!

 

either way you been waiting this long!! whats another week or so?

 

Forever??? I'm done being patient!!! I want my ST!!!

 

My dealer gave me Oil Changes for life so i do not have to worry about changing my oil (even though its so easy to do and i used to do it all the time on my old Focus)
