Mobil 1 vs the rest

You should've picked up the Fram Ultra, which is also good for 15k just like the M1 EP. That combo could be run to 15k.

You're not going to have any issues at 10k...in fact you could probably run the regular M1 for 10k but since they are the same price might as well run the EP for extra protection.

My Dad ran regular M1 in his Vibe GT for years on 10k intervals with never an issue.


The only bottle of Mobil 1 EP that I see that has 60-70% PAO is 0w20. All others have 20 - < 30.

I am on my first run of 0W-20 EP after two 15K runs of 0W-20 AFE. Both of those runs had 2.9TBN left and if memory serves AFE is good for 10K. If EP is truly a longer drain oil, it should be able to do 15K with zero issues (especially with highway miles).
 
The only thing holding me back from agreeing with you in running EP for 10,000 miles is the short trip drive cycle you have. That is usually considered severe duty and no matter what oil the car makers reduce the miles for an oil change. I am a Mobil 1 EP user myself and I am sure the oil is a perfect choice but me, personally, would drop from 10k miles to 7500 just because you don't get up to operating temp long enough to burn off condensation and such which leads to acids that the oil has to neutralize.

just my opinion though
 
I do 10K OCIs with 0-20AFE and my engines stay like new clean and both engines are smooth and quite. Also I use MC filters and they are more than good for higher mileage OCIs. Sorry a little fuzzy.

"Highway miles" is the operative word to extended drains of any oil, even EP.

Sadley, the average city driver thinks they can safely short-trip their car 15,000 miles and be be perfectly safe.

Highway driving is becoming more of the exception today than the general rule.

Yep, that's why many suggest at least one UOA at 10k even on extended drain oils. Short trip M1 EP to death and I doubt you'd want to run it 15k, same for gold bottle Edge or anything similar IMO.

My wife's badly short tripped KIA minivan had gold bottle Edge down to a TBN of only 1.8 in 7k. THAT is why you do UOA's.
 
I used M1 15W50EP religiously around 10 years ago back when they made it. I always felt it was a much better oil than the current 15W50. Wish they still made it.
 
Walmart could care less what the blend is, they likely require it to meet basic current specs and they want it at the best price they can get, period.

I did just check the 0W-20 because that is what I'd use on my Focus. My bad...still group 3 oil with extended performance additive should be able to 15k. Castrol Edge EP is all group 3 and is listed as 15k OCI's. If the vehicle is still under warranty the max OCI on a Focus is 10k which should be no problem on any Mobil 1 formula.

Good for another 3,000 miles then with a TBN of almost 2! Joking... am I?

I wouldn't worry about going 10,000 miles on a Ford filter. A lot of Ford vehicles these days have 10,000 mile/one year oil changes.

My 14 Mustang GT calls for this oil change interval or use the OLM and this car runs a fairly small FL500s filter.

The main thing to consider is if the engine is in excellent condition with all maintenance performed on time.

A Ford oil filter will plug-up just as fast as most others when adding a high detergent quality oil to a neglected engine and it's no secret that the majority of engines out there are getting more neglected / abused all the time.

This is where the uninformed customer gets in trouble thinking they can go for 10K - 15K on their somewhat neglected engine and try doing it on a standard oil filter.

I think it's the other way around. A lot of people are suspicious of long OCIs. On BITOG there are people proclaiming almost everyday to change synthetic at 5k or your car won't make it to 200k miles and keep repeating the old phrase "oil is cheap engines are not".
 
There have been a few less than stellar Motorcrafts lately IIRC, might want to check out the specific filter than fits the Focus.

Something does not add up, 7 miles a day 365 days a year is less than 3000 miles a year... yet a 14 Focus has ~8500 at the last time the signature was updated? Service may not be as short trip heavy as daily commute would seem to indicate.

At any rate I've run 5/20EP for 10,000 in semi severe service and it retains good TBN in most runs. Posters have stated TBN is not linear.

I think you're right. If you scan the 'Post Your Latest Oil Change' thread, most posters are going between 4,000-7,500 miles between oci, on synthetics.

I tested ST Syn and did UOAs in my '04 Jeep with the 4.0, along with M1, VWB and Amsoil. It held up at 5000 miles as well as the other oils so at that distance IMO there is absolutely no worry about using it. If you're not planning to extend your OCI.....

From the MSDS, the 0w20 does have the highest PAO % @ 70%. The ultra hi viscosity PAO's Mobil uses in their oils is being used sort of as an additive, varying %'s across their lineup depending on their formulating target/goal.

Interesting. How many months was it in service? Was this the EDGE advertised for 15k mi?

There is the 1 year or 15k postulation for M1 EP that I assume is meant to account for short trips. If you short trip a lot you will reach the 1 year long before you reach 15k mi.
