You can use any high quality 5W-20 oil that meets Ford's specification.

The use of synthetic oil (my personal preference) certainly isn't required but it may be a good idea for extended oil change intervals.

 

The last paragraph is true, if you use an oil that doesn't meet the original specification could cause issues. A heavier weight oil is harder to pump than the specified 5W20 that was filled at the factory. Heavier oils could also increase friction reducing engine performance and decreasing fuel economy. If you stick to something that meets the ford specification that is 5W20 and is api certified you should be fine, but with dyno/fossilized plant oil you will need to run used oil analyses to determine the alternative change intervals vs the factory semi-synthetic oil or going with a full synthetic oil.

Warranty covers it should any problems arise.

Mobil 1 full synthetic 5W-20 in mine.

 

cooking oil with my own additives.

 

Hows that working out?

anyways as long as its 5w-20 you should be fine, but look for synthetic blend just because its recommended. Wouldnt hurt to have fully synthetic if you want, but either works

 

Mobil One Full Synthetic, Motorcraft oil filter.

 

What I have been doing is taking my car into the nearest dealer every 5K miles and having them do the oil changes with the Motorcraft Syn-blend... I'll keep doing that until my 36K warranty is up. I may switch to full Syn on my next (20K) oil change.

 

Pennzoil Ultra.

 

+1. Lowest volatility mass-market oil available = good for intake valves in a direct injection engine like the Focus..

 

Would 0w20 cause warranty issues?

 

Read the original post (or your owners manual).

 

For my first oil change I went full synthetic. (Pennzoil)
From what I have read on the net it's better then Dino oil
In every way. And since that I have done that I am now getting 7.4L/100km.
Went down .3L in fuel usage. I'm sitting with just under 9000km on the car

 

*for the record, I consider Pennzoil Ultra to be one of the very few over the counter lubricants I would use in a pinch.*



Ultra is not a full "true" synthetic. The API SM formulation was 100% group III hydrocracked "highly refined" petroleum. The API SN formulation is rumored to be group III+ GTL (Gas To Liquid) technology, bought exclusively by Shell from Quatar.

Ultra, from Pennzoil's statements, at one time contained no group IV PAO or group V Esters......and at one time did contain some group IV PAO. Pennzoil has changed the Ultra formulation more than once, so who knows what it contains these days.

+1. Lowest volatility mass-market oil available = good for intake valves in a direct injection engine like the Focus..

I'd still like to see a true lab report on this. Again, "rumors" state GTL has a slightly lower NOACK than a PAO/Ester formulation, but still simply talk. If it is true....we are only defining a .75% difference in volatility.

Even the resident experts on BITOG agree this information is too shady to trust.

 

Mobil1 5W20 full syn here.

0W20 shouldn't cause any warranty issues as it's actually rated better for cold engine starts than 5W20, but there's not real added benefits to running it unless you live somewhere extremely cold.

 

whatever 5/20 my oil change places uses (been going there for about a decade). first oil change at 3k and future oil changes at 5k miles. i've always changed my oil at 3k miles. this will be the first vehicle for 5k oil changes.

 

I'll go with M1 synthetic (used it in all my vehicles since '92) when Ford quits giving us our 5k oil changes for free which I thnk is for 3 years.

 

I just use whatever the dealership puts in there. I figure if I have a failure that they can't say I didn't use a ford filter or oil.

 

Amsoil

 

owners manual:

"Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the requirements of Ford specification WSS-M2C945-A, SAE 5W-20 and display the API Certification Mark."

 

Calm down guys... No need toget your panties wadded up over oil preferences

 

I agree, as my opinion is that Ultra is one of the best over the counter lubricants available. However, the experts are still questioning the elusive spec sheet.

And Redline?

Edit... Beast got ya LOL

 

Get ready for some more wadded up panties... I'm using Ultra 5w-30

 

Nooooooooooooooooooooooooooo

 

Mobil-1 Synthetic in everything I own that has an engine.

 

Mobil 1

During the winter I like to use the recommended 5w-20(Mobile 1 Full Synthetic) , but when it gets hot out I like running Mobile 1 Full Synthetic 5w-30 every once in a while. I Usually stick with the 5w-20 though just to stay on the safe side.

Just be aware that 5w/30 doesn't meet Ford's oil specification for the car (WSSxxx945) and Ford could contend you haven't done your part to maintain the warranty.

 

Good point.I didn't really think about that so thank you.
