Mobil oil change every 15000 miles - 116,000 Mi on it now let's take a look at the filter

[Quentin]

So. I am the owner and also sent the Fumoto valve. I changed jobs starting Monday from that commute to a much shorter one and plan my next change at 10k. Basic maintenance I do like oil changes and filters but I farm out bigger stuff to a local Pep Boys except the big one of plugs and etc. I plan a BG with them next oil change and they will let me scope it when I do that. Great people there.

So there will be before and after on that. The Mobile One changes said 20k but I stuck with earlier change intervals from once I started after the first year of free changes and Mobil One said 15k miles.

So plan on more from me sending things!

Anyone want me to add in my used 2016 F250 6.7l with light use for weekends towing my boat? It was a fleet truck I got early in the pandemic at 115k or so. I do have an Edge III tuner on it but it is my toy I replaced my rusted out 2002 F250 7.3L with because rust was winning.

Wife was in shipping so anything is sent proper per regs. I do IT but love wrenching when I can and maybe later can add my 1993 MR2 engine swap project if they ever fix my bad shoulder neglected due to covid.

I’ll stick with my 3000-4000 mile oil change interval…..I like getting under the vehicle and doing visible check on things while doing oil change.

We have a 95 Grand Cherokee with the 4.0. We got it with 40k on it in 2000. At the time my father did service work in the Maryland, DC, Virginia and West Virginia area. He put a ridiculous amount of mileage on it. We were doing 2/3 oil changes a month. When Mobil first debuted the 15k oil, we switched to that their M1-301 filter. Even with that we were changing the oil once a month and the filter every 7, 500 and topping off. It has 400k on it now, has been retired from daily service, it doesn’t use 1qt every 5k and other than a valve cover gasket has never been apart. Last time I did a compression test was at 350k and it was still at 150psi across the board.

The gritty you felt with gloves was the 6 miles of dirt roads 🙂

I personally think the cleanliness of this is due to the long trips per day at highway speed, with the engine getting to temperature and staying there.

Been in auto repair since 69.and I have to say that Wix filters are by far the best I've seen. Highly recommend them. They are a little pricey but it's your car, you make the choice.

I’m amazed at how good that filter looks! I think I would be very nervous going this long between oil changes! As the saying goes “oil is cheap and engines are expensive “ I think it needs a little updating “oil is relatively cheap “ still cheaper than a new engine! It’s still good to know that with good oil and a good filter it is possible to go that long between changes but I’m sticking with 5k changes good oil and filter. It’s just peace of mind for me. Thanks!

It would be interesting to see a spectroscopic oil analysis of his oil. I have done this with Amsoil Signature Series oil on about five different vehicles. All of them were run between 85, 000 and 110, 000 miles. I never had any engine problems with any of the vehicles. ( Chevys and Fords) By looking through the fill caps in the valve covers there were no evidence of any sludge or even a coating of tan varnish. I never added any oil in any of them between changes and none were ever more than a half quart low on the dipstick. I sent two filters to another filter examining technician who posts on you tube. His followers criticized my 15, 000 mile filter because it contained a minimal amount of black sludge within the fibers of the Amsoil filter. The other filter that I sent had only about 5, 000 miles on it and was very clean. It actually could have ran at least another 5, 000 miles, but I always replace oil filters when the oil is changed. I enjoy your videos and look forward to your technical expertise.

Years ago I worked for Wix at the time we made FOMOCO, NAPA, Volvo, Sears, and Wix. All the filters were the same except for the color, logo, and package. I still use Wix and NAPA filter because I know they are good even though they are not locally owned anymore. An oil change is a cheap maintenance item and is the life of an engiine so I stick to changing at 4K to 5K miles.

Hi Guys,
In Germany we only change our oil once or twice a year. I have seen this for short trip cars and long trip cars. I personally have never lost a car due to engine failure, just rust. I think the additive package might be different? The oil costs much more than the US and is either full synthetic or hydro cracked. I have never seen Dyno oil used in cars. It is a very interesting topic.
Thanks for doing this kind of stuff👍

Your presentations are some of the best on Youtube. Even though we do not agree about oil change intervals. The fact you that you made this video for us your viewers. Shows that you are a true automotive enthusiast. Not just some guy wrenching down at the dealer. Your home owner videos are pretty good too!

His driving habits work well with extended drain intervals .He’s racking up mileage quick so his engine hours per mile are low. He’s in Florida and running 36-46 miles at a clip so the oil gets good and hot so no condensation issues. He’s using good oil and a good filter.I’d like to seen an oil analysis of the oil especially the silicon, tbn and fuel dilution . Keeping his air filter and intake tract maintenance up is the key to long engine life in his situation on 6 miles of dirt road a day.

I was a long distance commuter (65 miles each way) for 30 years and found that 10, 000 mile oil changes with synthetic worked fine. Since retiring I don't exceed 5, 000 miles or one year.

[SHOKona-wpvr]

Everyone has their own preferences for maintenance. I have always changed my oil at 3k even with Mobil 1. Good channel for information like this.

I have a 2012 Honda Accord 2.4L with almost 215, 000 miles on it. I change my oil every 10, 000 miles with full synthetic and use Wix, Mobil, and Napa oil filters. I’ve had zero issues with that car.

[chrisrossman]

Some engines are easy on oil, some are very harsh. My Wife's 2.0L Ecoboost is pretty black at 4K. My old Taurus with the Vulcan V6 with over 300k on the clock would look great at 15, 000 miles. The body was rusted out so I wanted it to die.

My experience...In 2010, I bought a used 2005 Ford E250 van with the original 5.4 liter engine and 345, 000 mi. I had no exact record of the previous oil change history. The van was being used for contracted emergency freight pick and delivery from state to state. I used it for the same purpose, which was mainly highway driving. Often, I would get oil changes at Walmart and mainly used Mobil One Extended 15K oil and filter to cut down on the need for oil changes since I might drive 55-65K miles a year. I drove this van for another 5 years for work and kept it after retiring . I finally sold it in late 2018 with 725, 000 miles and no major engine repairs. The engine was still running well. Often, I did need to add oil between oil changes...maybe 1-2 quarts as the engine got older. And yes, I did sometimes mix regular Mobil synthetic or other synthetic brands. This oil change schedule worked for me. It might need to be adjusted for more stop and go driving. But the Ford 5.4 liter was one of their best, I think.

I use this same wix filter on my 99 chevy blazer 4.3....along with 100% synthetic oil (costco /kirkwood ). I am a retired truck driver, and most of the companies I have worked for over the 38 years used with filters on all the trucks and seemed to get maximum mileage and service regardless of engine. I will continue using wix filters until I can't drive anymore.

[joeythedime]

Very nicely made filter. It would be interesting to see the results if he sent a 15k used oil sample into Blackstone. Those Subaru 2.5l have the filter mounted on the very top of the engine... that's a crazy amount of dirt/sand for filter mounted so high. I would be changing my air filter every time I change the oil!

[ronaldrussell]

Of course the oil feels a little gritty, you've been handling the outside of the filter that is caked with dirt!
