Pretty much self explanatory. Am running Rotella T6 15w-40 presently. I have 10K miles on it. Will drain and sample it at 20K. I average 2K-2.5K miles a month, so I should have the next UOA August or September.

Wear metals look great at 10K.
Your TBN is already at 2.5. I'm curious to see it for the next 10K?

The highlight is that this is a Ford Focus 2.0..

You are shedding no metals... on a HDEO.

My only question is there any difference in MPG? Would you have the same report on 5w40?

Silicone (sand) is >4X higher in the second sample. Check your air filter.

HDEO oils are some of the best oils on the market. Great results are expected if the 15W start up viscosity need are met.

If you read report.. it was the first sample, and it notes the use of sealer.

Duratechs are great engines....I was under the impression that they preferred thinner oils?

Am I correct that you ran two 15K OCI's and are now trying 20K?

Yes pbm, this was my second 15K stretch. I pushed SuperTech 5w-30 Synthetic for 15K and Blackstone recommended I could try it to 17k! When the engine had Supertech in it, I replaced the valve cover gasket and used a good amount of RTV around the spark plug channel gaskets and the spark plug valley gasket as well as several junctions where the factory specifies its use. These are infamous for filling the spark plug channels and valley up! Not enough tension in the center of the cover apparently ! That is why the silicone was high on the last UOA. Even after repairing the gasket, the Duratec seemed to use oil, but not as much as my wife's Ford designed, Mazda built 3.7 V6. I bought this car to commute to work and it was used with 100K miles on it. Decided I'd experiment with oil for my entertainment as well as everyone else's. My first UOA showed that SuperTech is a great oil. The second showed that T5 is a great oil. I'm sure the next UOA will show that T6 is a great oil. I was planning on using a 5W-40 next go around. Probably Delo but will go with whichever has best promotion. I can't say for certain that the thicker oil burns off less because I don't know how much of the 5W-30 was getting pumped into the spark plug channels. I used a Ph3600 sized,double the capacity, oil filter. It was a Wix closeout from Rock Auto.

Sorry, but I don't believe internal drag from a heavier grade oil will make a difference in fuel mieage that is measurable outside a lab. If a car gets a street measurable difference in fuel mileage after switching motor oil grades, it's more than likely driver behavior and other forces at work. The ONLY reason that the thinner and "super thin/0W-16, 0W-20" motor oils exist is so that the manufacturers can squeeze an extra 1/10th of an MPG out of a vehicle on a lab dyno or treadmill during MPG testing. If I want to make my car get better gas mileage I pay more money and run 100% gasoline with no ethanol. My Focus gets 30-32 MPG on Ethanol. It gets 33-36 MPG on 100% Gasoline.

As somebody that currently owns 3 Duratechs (a 2.0, 2.3 and 2.5) and has a daughter with one (a 2.0)....I read most posts pertaining to them. Most agree that they are durable engines and easy on oil and several owners have mentioned that they prefer 5w20.
If you doubt it...that's fine...

I put 2500 miles a month on my Focus and will probably do so until I retire or get a closer job but I doubt it. The car is a hoot to drive. I plan on installing a STEEDA rear sway bar that is HUGE and that should make her corner even better. My plan is to driver her 300K+. I paid 4 grand for her and decided to use her as a rolling lubrication experiment. Am looking at going to a conventional oil after this 20K interval. I'll do a 7.5K interval. Change oil and filter with identical oil but add LubeGard additive. Do another UOA at 7500 and see how the samples compare. I learned 20 years ago that Lubegard works after watching our CVPI patrol cars get retired after 250K miles with the original trannys in them. Out tranny shop swore by LubeGard ATF additive. So I'll see how the oil additive does!

Thanks for great UOA's! What a great oil.

Heavier oil in a Focus? Sure. I looked in a 2006 Focus owner's manual published for UK model owners. The recommended oil grade was 5W-30 for the very same Duratec 2.0 that NA owners are told to use 5W-20 in.

Also the factory OCI over there for that car is 12,500 miles or 1 year using Ford spec WSS-M2C913-C.

Again, thanks for the 15K UOA's.

2k to 2.5k a month sounds like mostly highway miles. Did I get that right?
