Oil change

So your OLM comes on every 1,000 miles? I use mine, works great.

A great many years ago, engine tolerances and oil performance improved and recommended oil change intervals for cars and light trucks were generally set at 7500 miles. Lots and lots of diehards kept with the old 3000 mile recommendations. Some still do. I used the 7500 mile recommendation. My Izuzu died when the A/T quit at 290K miles. I sold my CRV at 190K when I retired. The engine seemed to be perfect with almost no oil consumption.

Now my Ram uses synthetic oil and calls for changes at 15000 miles. I will follow that recommendation. Anyone who doubts the manufacturer's recommendations can have the oil tested or just change the oil much more frequently than needed. Your shop will be happy to do so.

That's probably because you change it so often. You're bound to forget to torque the drain plug. ;) :B

Awwww man.....that’s salt in the wound! Lol
At least it was only a cold sieze and didn’t hurt any rotating parts.

Changing oil is obviously a personal choice, and just as obviously, it depends on personal interpretation of the owner's manual.

In my case, I change the oil every 5000 miles, regardless of what the OLM says. My owner's manual indicates the oil should be changed at 5000 to 7499 miles under severe use. My manual defines "severe" as Moderate to heavy hauling or towing, mountain or off road use, extended cold or hot weather operations. My 2014 truck has almost 69K miles on it already and over 50% of those miles has been towing. Also, since my 3.5L twin turbo engine is known to cause some oil dilution, I just change my oil at 5k miles. I've used Motorcraft semi-synthetic oil since the beginning.

Am I changing it too often? Maybe, but that's OK by me.

As mentioned, I drive a F150, 4x4, Supercab, 163" WB, with 3.5L EB & a 3.73 LS rear end.

I can tell it had Delo from the black streaks.

My 98 12V’s first 50k had delo. After I ran AMZ/OIL 15-40 Diesel Marine. I did the KILLER DOWEL PIN at 100k. The inside of the front had black streaks. At 120k we did my Dads 94. It was spotless ands golden color.

My Dad used AMZ/OIL from the first change on.

Does it matter? No idea but that is what Delo leaves behind.

5000 miles for me .

Perfect.

That is all the OP wanted is to hear what you did.
No cross comments, justification or dispute of others.

How many engines you had that spun a bearing or dropped a valve or any other number of catastrophic failures before their time to make you paranoid to send in oil samples?

I’ve driven more than 1.25 million miles since getting my license in 1977. I’ve had a variety of vehicles from some nice ones to some pretty crappy ones. I get a minimum of 150k out of a vehicle and either something else happens to the vehicle other than engine failure or one of my kids gets it.

I always follow manufacturers guidelines regarding maintenance. have never had an engine failure of any kind. Never. I can see no reason to do anything other than manufacturers guidelines, and since I’ve never had an engine failure, can’t see testing my oil. It wouldn’t change my maintenance habits.

Yeah that was a drunk post, sorry, but the message is the same....who cares....
And I’m not a metallurgist but I’m aware of all the things you’re talking about. Just don’t care. I guess if a person knew the engine was starting to go tits up from an oil analysis, then could sell it while it still ran well. Otherwise wouldn’t you wait until there were symptoms before dropping the coin on a rebuild?

Maybe I’m lucky but idk anyone else who’s blown a newer engine. Not all the miles I’ve driven. Is this a real problem or a solution looking for one?
