Yes says Blackstone.

7400 miles on this oil and TBN is still 2.5.

5000 mile OCI is for fools.

 

Somewhat boring video due its length but its interesting for what it shows. Ho hum though since Blackstone wouldn't buy me a new engine if I suffered an oil failure leading to engine destruction. I myself find a 9K or even 7.4K OCI foolish but then again I'm paying for my engines etc.

Thanks for shiaring this Jshira!

 

my 2014 ford C-Max Energi has had 3 oil changes. 21,000, 40,000 and 60,000 all exactly two years apart as per the dash message to change oil soon. Manual says message may come on any time up to 2 years and or 20,000 miles. Car has 61,000 on it now. My only disclaimer is I do not know how many miles are with engine running vs electric drive but still oil is in there for 2 years! I have Ford dealer put Mobil 1 0w20 full syn in.

 

Yes well, most people believed that the world was flat for what, 20,000 years?

So you will get there. Give it time.

 

You're too optimistic JSchira----and I'm equally obstinate!

 

Bump:

Was re-reading this & it happened to dredge up a mid 1954 conversation happening, at the local garage I sorta hung out at, when something interesting was going on, like a engine opening up / tear down / rebuild, by the garage owner, a former Tech at the local Cadillac dealership, that had decided to leave to go into business for himself.

Anyway, Cliff was a Very experienced, savvy & Honest Tech & was talking to the owner of a brand new red on red Mercury with one of Fords new ohv Monster V8, about a early oil & filter change. This guy was a well known Electrician that liked the latest & greatest in vehicle technology & this vehicle had some going for it.
Spin-on oil filter & 10W-30 oil specified!!!! I walked in just as the oil part of the conversation came up. Cliff could have used & sold any brand oil he wished but chose Texaco oil & gas & the subject was about new Havoline multi-viscosity 10W30 & how Texaco & Ford said it was good for a 3,000 mile oci, which was 3X the standard 1,000 mile oci using straight weight 20w20, or 30 in summer if your engine was modified, or used oil. Anyway SAE 20 & 1K oci was the standard oil change interval & here Texaco & Ford were saying a 10W30 could be used in this engine & for 3K miles, It was mind blowing, because no one under stood the new multi-viscosity oil technology, refining, or oil additive packages that had been developed, tested & now coming on line that could make this happen..

I was skeptical that oci could be increased 3X without awful engine deposits based on what I had witnessed on engine tear downs, using other brand lubes at this garage & that a 10W could possily provide lube protection for such a large & powerful engine. All because none of us at the time, fully understood what 10W meant in a multi-viscosity lube, nor anything at all about engine oil additives & danged little about oil filtering or wear!!!!

Now fast forward 6 years to about 1960, after my Navy Air duty, being exposed to some of the Then latest engine & lube technology, I was back in the same garage, looking at the Same Merc engine being opened up for a internal refresh, after many miles of use. Off came the valve covers & it was squeaky clean under there, no gum, no varnish, no tar, no black gel, no black or grey sludge, or baked on hard carbon deposits, just clean metal, after the dirty oil was wiped off!!!! I was impressed....Impressed......IMPRESSED!!!!
I couldn't believe what I was seeing but the story doesn't end about No deposits on the top end, the oil pan was clean, no scraping or burn-out needed to clean it up. The piston ring lands, valve lifters & stems were clean. No wear ridge atop the cylinder bores, cross hatch still good in all bores, pistons weren't scuffed. All this puppy was going to need was new crank & rod bearings, rings & a mild valve regrind to freshen the seats a little. All this got my attention & made me want to know more about how this was possible. Maybe after all the years, what I had seen & heard about our then (1957) latest jet engine Synthetic aviation lubes & additives in the military, was Finally making its way down to us poor civilians!!!????
SO, for we poorly informed civilians, it seems we're still the last to be exposed to the latest & greatest technology, sometimes on some things, as much as 50 years behind!!!! lol

With the closer & faster computer control advancements in manufacturing engines, materials, refining of lubes, additives, filtering, engines find themselves tighter sealed, better lubed & filtered, thus running more efficient & Cleaner, so pollute less, over longer times, thus we don't have to change our oil & filter as often on New vehicles, as we learned to in the past on our older rides.
SO to know if we can run our newest lubes & filters longer on our Older higher mileage rides, don't guess, consider having a used oil & filter analysis performed, to see how our choice of lube & filter hold up under our drive cycle conditions & choice of extended oci.

 

February of this year I HAD to change my oil, 5.4 Ford reman'd engine with barely over 20K miles since the refresh install. Typically I don't run past 3-4K at most, this time weather was so bad outside, I was so busy working and driving the E350 there was just not a convenient time. It had gone 6,674 miles on Motorcraft 10W-30 direct from the dealer, using Motorcraft FL-820s filters. I didn't think to save any of the used oil which would have been a great way to test it via Blackstone or similar if only for my own peace of mind.

That engine is either idling for rather long periods of time or running at highway speeds so how that use affects oil properties at that interval would have been great to know. I doubt I'll ever go that long between oil changes but if I do the analysis will be top of mind.

 

No offense, but you have made it quite clear that you will change your oil every 3000-4000 miles regardless of what the science tells you. So why would you bother with a UOA?

If the UOA says you can go to 6000 miles, will you?

Seems like even more wasted money to me.

Unfortunately, the trees in my yard do not bear $20 bills.

Glad that yours do.

 

I agree, this oci would have been a Really good time to have at least performed a UOA. Idling for long periods is Severe Service But you mitigated it some by using a good semi-synthetic oil mixed with some highway driving if was long enough, could have helped tidy things up a bit so you might have been surprised how well this oil recipe held up.

Lots of public service, police, taxi vehicles do this every day. Some are never shut down between shifts, so run 24/7 between oci!!! So with the oil used, low engine mileage, I wouldn't be too concerned about a one time event of this length.

 

You've long advocated extended OCI's which is fine with me I'm not responsible for your vehicles. You're free to do as you please with your own vehicles, same for me. If I have an engine problem due an oil issue and I've followed your "advice" will you stand the expense?

Having just replaced the current engine to the tune of about $5k---massively cheap cost using nothing but Ford parts---that's one helluva lot more than a $30 oil & filter change every 3-4K miles. Simple cost comparison convinces me I'll do what works because it works for me. Like you I'm concerned to a small degree about money but $30 vs potential $5K + plus loss of vehicle use wins out every time. If a $30 maintenance step every 3-4 months is an affordable cost maybe I shouldn't be driving at all?

 

Yes, yes, yes. You have explained all that before and I get it. I accept it as fact.

But that was not the question.

Based on your insistence on a 3000 mile OCI, why would you bother spending the additional money, an expense that has nothing to do with the cost of rebuilding a burnt engine, on a UOA?

If the UOA says that your oil is good for 6000 miles or more, are you going to change? Your posts say not.

Your 3000 miles OCI is an artificial number determined by yourself, not science. If you are going to ignore the science, why would you spend money to find out what the science says?

Change your oil at 3000 miles if that makes you happy, but you cannot ignore the massive amounts of data that demonstrated clearly that modern oils do not need to be changed that often. Do you really need to pay $$ to Blackstone to remind you of that?

 

That statement, on its face, is inaccurate and I take it back.

Obviously, you can ignore the data because that is, in fact, exactly what you have chosen to do.

 

you can read my posts earlier in thread about my 2014 C-Max Energi on two years and 20-21000 mile intervals. I also own a 1987 Thunder Bird Turbo coupe that I bought used in 1995 with 37,000 miles on it. The previous owner that bought car new told me he changed oil at 4000 miles with green bottle 10W30 Quaker state. I was some what alarmed he used an oil known for gelling up and then using it in a turbo charged engine. I started using 10W30 Valvoline All climate that was newly marketed as Turbo approved since the old Valvoline Turbo IV formula was no longer available. at 2000 mile intervals. I found that if I drove the car the way they designed it, it consumed a quart to 1000 miles. Driven like an old lady used zero. I did that until about 50-55000 miles and switched to Valvoline 10W30 Dura Blend and car consumed less. Finally at 70,000 miles in year 2000 I decided to switch to Mobil 1 10W30. I then left on a 10 day 4500 mile trip, drove the car as was designed and it used ZERO Oil, didn't even budge on stick! Since then it has had either Mobil one or Valvoline full syn at one year or 5000 miles and has been High mileage version since about 125,000 miles. Last month I decided to change the valve cover gasket at 178,000 miles while I was doing the annual oil change. The under side along with top of head were brand new clean like it was built yesterday! Car also still does not use any oil at all. I kinda feel like I have changed it too often, I will continue on at annual oil changes but am not scared to go more than 5000 miles. I buy the oil and MI oil filter at wally world for about $30.00, this last change was Valvoline High mileage full syn 10W30. This Fuel injected Turbo charged Pinto 2.3L lima engine is stout. Put over 600 miles on it last week at 72mph and it returned 30mpg. My son will eventually get the car..

 

Correct on both counts----it is MY CHOICE! Why you continue to badger others into seeing your view or accept all this collected data escapes me. We've read it and CHOOSE to continue on our own path anyway. If you were paying for these oil changes I could see the interest otherwise STFU and let others maintain their vehicles to their own liking.

Again, MY vehicles, my money so MY choice!

 

I am not badgering you at all. I understand that you are going to continue with your 3000 miles OCI no matter what I or anyone else says. I have given up on changing your mind on that issue.

If you read my most recent posts carefully, it will be clear to you that I am responding to your most recent post stating that you were interested in what an UOA might have said on your oil that went 6600 miles, and I posed the question that if the UOA came back very positive, i.e. that the oil was good and could go more miles, would that influence your 3000 mile OCI.

Based on your reaction to my question, it seems that nothing in the UOA will make you change your mind. No big surprise there.

But, given your well articulated position on OCIs, I am bewildered as to your desire to obtain a UOA.

Maybe just plain curiosity, I suppose.
