By *general* consensus on this forum, it seems dino can go 5K easily

So that leads me to... which motor oils can go to a 10K mile OCI?

Does this get into "you better do an oil analysis" territory?

Thanks
 
Most full synthetics will go 10,000 OCI's depending on your driving habits....but its as important to use a good upper-tier oil filter....stay away from those cheepo filters with paper media...and spend a couple extra bucks on a Purolator PureOne, Bosch Prem.,or Mobil 1

Using a quality synthetic with a cheepo filter, negates and messes up the quality oil you put in your vehicle, and wears out your engine much out faster.

Of the top of my head, Mobil 1 EP, EDGE, and Amsoil SSO can do it under normal conditions. Pennzoil Platinum could probably do it too but I would get a UOA done at like 7-8k to verify.

Not what we've seen with 5-block commutes in a chrysler 2.0.
 
It depends on driving habits and condition of the engine. Mobil1, Castrol Edge, Pennzoil Plat, and Ultra should all be up to the task.
 
The oils that meet BMW LL-01 can do 10K. Mobil 1 0W-40 and Castrol 0w30 being two examples.
The Mobil 1 EP line and Castrol EDGE both claim 15,000 mile potential longevity.

A small crankcase coupled with severe driving conditions would be a sound argument against 10K changes.

I first went 10K with M1 oil in 1978 in a 78 Dodge pick up slant 6 in the state of Maine. I have been doing 10K OCIs ever since in all kinds of conditions, even those Arco mentions. I know several people doing the same thing with M1 oil, and some going 12-17K OCIs. My sons 91 Ranger has 340K on M1 with 10-14K OCIs and often his work truck doesn't leave town for days on in. Is M1 oil good for 10K? Of course.

Yep, I've done 10k and more (15K once) for the last 8 years on M1. Vehicles run great and are spotless (when removed valve cover this year).
 
I don't waste money on oil analysis myself, however I should one day just to see what I have deep down in that there fill hole...

My lil Accord gets 7500 on conventional, so I feel comfortable even on the cheep synthetics to run 10k OCI's. I in fact try to give myself some room for oil change by running the EP type oils during the colder months, I have no problem pushing Edge or Mobil 1 EP oils out to 15k if need be, however most of the time they get changed around 13k weather permitting of course. So my point is the type of car you drive, oil sump capacity, and many other things do play a part in your OCI, that's why the manufactures vary so much when they state the specified/recommended OCI. I would first check the manufacture OCI, then you could be the judge yourself if a synthetic can extend your OCI out to 10k

Do you have proof that using a NapaProSelect other than a NapaGold or PureOne for example with synthetic will destroy the oil and will wear/destroy the engine much quicker!? If not, please refrain from making asinine statments. If you do, I would like to see this proof.
 
The answer also depends on the engine, no? From what I've seen here, seems turbo engines are much harder on oil and need very good synthetics to handle 10K OCIs.

Or maybe it's just VW/Audi's 2.0T that's really tough on oil.

Aren't diesels also hard on oil?
