Are extended drains really protecting the engine?

I have the exact opposite experience. Fresh oil always feels smooth to me. Very noticeable difference.


Which just proves that anytime anyone says they can "feel" a difference with an oil change (assuming same viscosity) then they're fooling themselves.


Read my later post.

I do hope that I gave some of you some food for thought on this.


No problem.I understand that you had a bad experience with M1 with your Escort. My daughter had a 86 Escort ESP with the hopped up engine and we did the 10K OCI with no noticeable problems. I think what ever you feel comfortable with is the way to go.


Thanx tig,I have since gone back to the synthetics,and so far am pleased with the results.(i gotta trow this in

) but only on 5k oci`s....

(I figured you could use a chuckle out of this)

Webfors had a good point with this observation:

"But forget about them. Honda and GM's OLMs are routinely pushing OCI's past 10k, and these cars are manufactured, designed for and sold here, with *conventional* SM oil listed in the manual. I for one would only follow the OLM with a quality syn, but that doesn't change the fact that Honda and GM are confident in these intervals with conventional oil. Definitely pushing the limits IMHO. But using a quality oil designed for extended drains and the OLM becomes conservative."

So there is some 'evidence' here that your thinking is generally NOT correct.

But, as you said, you are free to do what you want!

Why not? Just curious...

This has always been my experience. Both the Golf & NB make no difference in running at all with 'fresh' or 'old' oil in the crankcase.

Since when is 10k miles 'extended'? That's the standard interval on both my cars. The Golf will be getting a change this week with 21k km (~13k miles GO METRIC ALREADY) on this fill of Schaeffer 9000 5w40. Were my commutes longer, I'm sure I could go at least 25k km or more without concern.

I`ll tell you what would be interesting addyguy,you and I tearing apart the motor after 100,000 miles of those oil monitor vehicles.Especially the ones going that long on conventional oil.

fsskier, goes up to 20K on M1 0-20. Has been doing it for years with differant types of engines and puts 300K plus on them.

That's funny! I'm still laughing. I actually sent him a PM about this and he confirms he has done this on several engines. Interesting to say the least.

Hahaha!!,I`ve got issues.

When my tC was under warranty 5k OCI's were needed to remain within the factory warranty period(stated in the manual as well).

On dealer bulk synthetic the tC would feel smoother after an oil change, quieter etc. Towards the end of the 5k OCI you would hear the rattles and noise of the engine.

The Impala was quiet regardless of fresh or old, it just purred all the time whether at a 3k OCI or a 5k OCI.

The Xterra hates oil period, short or long the truck sounds like its punching the oil in its face. The only thing going for an extended drain is saving your money and possibly easing the strain on some of your components.

Wow,I`m picturing that in my head right now

My head is starting to hurt.

Well I have had plenty of experience with 10K OCIs and have never saw any differance.

If the manufacturer suggests 7500 or 12 month OCI. Is it ok to run 10k on Valvoline Synpower 5w-20, or would you only do this on a specified extended performance oil like M1 EP?

If you are under warranty I would go by the book. If not The Valv Syn would be good for 7500 miles. 10K+ is no problem for the oil I use.

Assuming it's a daily driver (darn, forgot one qualifier ..and just like my old union shop, if you didn't keep your behind covered, one of your fellow workers was there to shove something in it "Hey, you're lucky I did that to you. A stranger could have done that ..and then how would you feel? At least I care"

) there would be way too much loading due to fuel enrichment ..the biggest filter clogging material...insolubles.

Now one taken out ONCE a year for a 3000 trip composed of 400 mpd events? It and the oil might make it. I'd check the outside of the can for deterioration.

If the NY means NYC then you are in severe driving conditions unless you only drive Sunday mornings and at late night. So these extended oci really cannot be as good as shorter oci, which get rid of all that blow by etc. If you drive in Utah everything changes. Most of these thoughts should start

with how you drive and under what conditions.

The OLM in my Buick usually starts blinking after approx. 6K (sometimes a little more, sometimes a little less). About 30% of my miles are in NYC...and often in stop and go traffic. Recently I installed a full PAO synthetic and the OLM went off at 5800 miles. I was disappointed that I had to drain it at such a low mileage.

You hit the nail on the head. Until I joined this site I thought severe service was normal. I would love to live somewhere where I could drive 30 miles to work at 60 mph. Anyone that drives into NYC to be in work for a 9:00-5:00 job or lives on Long Island knows what severe service is. My wife works 26 miles from home, she starts work at 10:00, so she drives about 35 minutes. The typical ride home is about 1 hour. A Saturday night home trip can take up to 2 hours for her.

A typical Monday & Tuesday, the car sees, about half a dozen 1-3 mile trips, stopped for 30 minutes or more. I want the junk out of the engine, so for me everything I own is considered severe service. I would not run any oil for 10,000 miles under those conditions.
