Excellent!! It's worth mentioning that Ford redesigned the regen in 23+ trucks. Instead of injecting fuel on the exhaust stroke it injects it by the DPF thus reducing or eliminating the potential for fuel dillution as a result of regen. At least that's my understanding and Ford isn't the first to do this. It's always a science class with Lake Speed and always enjoyable and educational. Thank you for this and for your channel.

DEF consumption has greatly increased in 2023 Ford 6.7s. My friend goes through twice as much, if not more, than I do in my 2017. Not sure where it's injected though.

[@mikeskidmore6754]

With cars and pickups it's cheaper to change your oil more often than it is to pay for the oil analysis .. GM recommends 10,000 mile oil change Intervals for my 2003 Duramax with a 10 quart capacity. I see the newer Duramax's hold 7 quarts. Older class 8 trucks hold 8 gallons of oil .. The Murphy Diesel in my crane holds 12 gallons of oil . My Duramax tells you when to change your oil based on how hard you ran the engine. It shows % age of oil life left. The Problem is if your batteries get disconnected it goes back to 100%. It's a good thing I wrote down my milage when I last changed my oil 4 years ago. I am just over 10,000 miles right now and the oil looks really good yet.

[@powerstrokemaintenance]

Thanks for the comment!

[@RobertSmithandfam]

Great topic. Is there a case where the oil might be still good, but the filter clogged reducing its efficiency? In the case of the extended change intervals, would it be worth considering changing the filter say every other drain? And on trucks, what about a larger oil filter than factory spec? Or, a bypass kit?

[@powerstrokemaintenance]

Great question. You definitely want a filter that will last the interval. Bypass filters do help. I run an Amsoil filter that’s good for up to 25,000 miles (I would never go that long obviously). If the filter was clogging you would see it with a poor oxidation value in the oil report

One thing I found interesting is that the more load that is on the engine the less the EGR is active. So that might be one reason why I am able to go further distance is because of they’re always a decent load on the engine. Also anytime, my truck is in park and engine is running. The idle is 1200.

[@robm3357]

I see people sending in oil analysis with very high miles on the oil and the analysis comes back that they could go even longer. I don’t trust oil analysis after seeing this. I have seen dozens of these and never seen one come back bad. Also consider the amount of sludge in the engine with long oil drain intervals. Diesel oil is full of soot, soot is what turns the oil black. Soot is abrasive.

[@jasonkubitz9410]

@@robm3357 I can see both sides of this. I am still old school and change my oil every 5K. Actually, I usually don't even hit 5K because I rarely drive my diesel. I use Hot Shots Secret Green Diamond 5W40 oil since they have a lot of data to back up their product. So far zero issues and it runs cooler. I was actually told by them that could go 10k easily since their test trucks have gone that or even further. On their other test truck, they installed another filter system and they have over 100K on the same oil. They just add TBN booster. Not one issues. My outlook is, do whatever makes you happy. Oil isn't expensive and if you want to change it at 3-5K, go right ahead. If you want to reply on an oil analysis, that's cool too. Changing your oil more often does not hurt it. It doesn't induce more contaminants by pulling your drain plug and opening your fill cap. If you have to pull you engine apart every oil change, I could see that being an issue. The only problem I see with doing oil changes too early is the cost for the consumer, filled up oil repositories at local parts stores, more strain on factories to produce/recycle more oil, and also the factories to produce more oil filters.

At least while it’s under warranty that is. I run my diesel very hard and tow at and above the mfgs limits.. So lots of oil changes. That includes transfer case and diff oil every 2 years. Also I drop the transmission pan once a year and then add 6 quarts to keep the transmission oil clean. Over kill, maybe.

[@jasonkubitz9410]

@@robm3357 I think you're doing everything right. This is my subjective opinion of course. There is a lot of science behind modern oils and I do believe anyone can stretch their oil change intervals. On the other hand, I've never heard of any adverse effects from changing oils too often. The only thing that it would hurt is the consumer's pocket book. My outlook on all of this is, if you purchase an expensive product such as one of these high priced diesels, why try to save a few bucks on stretching your oil changes? If you're worried about maintenance costs, you should be driving a Honda. Even my Honda Accord I change the oil every 5K. Is all of this overkill? 🤷🏻‍♂️ Can I afford to do it to give me a piece of mind? Yup. Like I said, I can see both sides of this argument but there's one method that has been tried and true for many decades. Oh ya, I work for the government and I can tell you they don't care how much oil they use. Testing oil is usually done during R&D to find a happy PM interval. Typically to avoid catastrophic failure which could lead to loss of life. Not so much for mechanical longevity. Unlike the government, we don't tear our engines down and rebuilt regularly.

Part of why I change the oil at 5k vs 10k mi is b/c I don't trust the dealers I have a choice to deal with in my local area. I caught one flat-out not changing my oil filter on 2 occasions before. When I change my oil at 5k & then have the dealership change it at prescribed 10k mi, I at least know the oil & filter was 100% changed at least 1x during the year. Note: My car does not have a dipstick & does not have a canister type oil filter. Once my factory warranty runs out I will just change the oil myself & will likely run a lot longer (based on U/O analysis) but for now I don't trust dealerships as far as I can throw them so changing out early is the only good way I have to know I'm getting fresh oil & fresh filter at least once a year.

Since modern day synthetic oils do not breakdown the way old school petroleum mineral based oil does I go by how long the oil filter lasts. I have a system called oil filtration road dirt efficiency percentage ratio (OFRDEPR)/road dirt percentage ratio (RDPR) to put it in layman’s terms how much garbage the oil filter is filtrating versus how full the filter is full of dirt. So I recommend 75% or 75:25 to 95% or 95:5 ratio of maximum that the oil filter can last. Oil change intervals/oil drain intervals (OCIS/ODIS) is based on the oil filter not the oil. 🙂

If your oil pan is only 4 quarts on a V6 such as my 2003 Impala, I change it every 3 to 4000 miles. Filter, every other oil change. The large caterpillar and Cummins diesel engines hold about 45 quarts and spend a lot of time on the highway. That is a lot of oil. My Duramax 6.6 L, I’ll go about 7000 miles, but it holds 10 quarts.

[@EngineNoise305]

I want to hear more about that car that would kill oil in 3000 miles. So if you drive for example to the train station every morning and evening 1 mile in 35 degree F weather only going 40 mph max, you’re adding fuel and condensation to the oil, killing it. Then on the weekend if you drive 30 miles on the highway, you can evaporate that contamination out. The reason why your(power stroke maintenance) oil can go for so long is because you’re always doing hot highway miles, and you have a super filter right? What your saying is highway miles have the following benefits: Gets oil up to temp, and lower blow by because of the extra engine torque yielding higher cylinder pressures. The combination of these remove the contaminates from engines?

[@powerstrokemaintenance]

Yes that is a good summation. Oil has an optimal temperature. If I ever stop driving as much highway as I do, I will retest. This same truck and oil would break down faster with shorter trips in cold weather. But right now I’m driving 8 to 10,000 miles per month of mostly highway

My coworker pulls our 14’ enclosed tool trailer with a 3.5 ecoboost and is the exact opposite of me when it comes to maintaining a vehicle, I’ve had a 3.5 eco and the UOA told me 7k was max with full synthetic oil. However, he waits until the 10k light comes the dash and then tries to change it sometime soon. He’s always over 10k and mostly closer to 15k. He gets it changed at his local ford dealer so they probably not using too tier oil. Anyway, he’s over 250k on his 2018 3.5 now with no oil usage and it drives me crazy

Question.....Why are the Sample dates the same and the 'previous sample mileage' showing 0, on the report on the screen?

[@powerstrokemaintenance]

That’s a sample of Amsoil 5W-40 straight out of the bottle for comparison

[@nicholaspetre1]

Don't know, I would prefer to change oil more frequently. Would rather buy any other good brand oil instead of this hyped overpriced Amsoil and change it more often to be on the safe side. For $270 for oil analysis and Amsoil oil change, I would rather change oil 2-3 times with Pennzoil or Mobil instead. Many mechanics out there will tell you to not overthink and just go with any decent oil assuming it fits your application specs and change it more often based on the driving conditions. It is that simple. Engines usually break not because of the most expensive oil was not used but because the oil intervals were too extreme.

Thanks for the comment

[@frederickwoodard9551]

If you read my comment it is 75:25 or 95:5 and it is based on whether you have a 10K, filter which is the maximum amount of mileage that filter can last so 7,500 to 9,500 is when you should consider changing your oil so, 9,000 OCI/ODI is not a bad idea to change your oil because you don’t want to stretch it longer than 9,500 or 95% of a 10K mile oil filter. The reason why you don’t want road dirt or sludge backing up into your oil. What I say depends on whether you use a 10K, 15K, 20K, or 25K oil filters. I never base my OCI/ODI on engine oil because you could be throwing away perfectly good engine oil. 🙂

Manufacturers have to take the average customer in mind when recommending oil change intervals. Small print says different conditions can change the intervals. The majority of auto manufacturers recommend 10,000 miles with synthetic oil.

[@powerstrokemaintenance]

Good point!

[@skylinefever]

In addition, some manufacturers overestimate how far that oil can go. I think about how many Toyotas sludged up because people changed the oil exactly when Toyota said so. Going 3000 on conventional or 5000 on synthetic could have prevented some of that.

[@captnjim44smith74]

@@skylinefever In the 1950s, Quaker State non detergent oil, usually 30 weight was the oil most people used. The change interval was 3,000 miles. Full synthetic oil is light years ahead of that oil, and filters are better, so changing at 3,000 miles on today’s engines is crazy in my opinion. Why not take a taxi or a bus instead !

@@captnjim44smith74 You also had engines with 4 or 4.75 mm oil rangs and a huge opening behind it for oil return. With modern 2.5 or 2mm oil rings and a few tiny holes behind it, a small amount of sludge will ruin the ring.

[@jasonkubitz9410]

I respect wanting to know how your engine is performing by doing this analysis but I think it's a little excessive. I mentioned before on one of your shorts, I think, that my buddy has well over 200K on his 2016 and he does not follow any regimen. He waits for the sensors to tell him what to do for oil changes, coolant changes, etc. He hasn't had any major issues. He tows his dump trailer daily for his business and I know that think can get heavy fast. I'm sure by doing an analysis you can save a few bucks on oil that's still good and potentially find an underlying issue but what are the metrics on those who do oil analysis and those who don't? Do the ones that get their oil tested have a longer lasting engine vs those who don't? I'm pretty sure that the vast majority of people don't do an analysis and there are plenty that don't even know this test exist.

Oil analysis is just another tool. Use it or don’t, totally up to you. I like the peace of mind it gives me. Helps cut through all the nonsense on the internet.

Oil and filters are cheap, just change them regularly "3000mi. - 5000mi.and the engine will last longer than the life of the car itself. My Analysis is to keep an eye on the oils condition, if it starts to look dirty I change even if it is before my regular oil service.
