Non scientific oil comparison

[riotwarrior]

I did this years ago with Amsoil 15/40 diesel full syn vs some non syn 15/40 just in my deep freeze....said lots then...this says more


Albeit wally world oil only has wee cap not big one...

Back in the day when I was a younger man back in Cleveland, I had several 2.3 liter Ford's including a Ranger, two different Merkur XR4Ti's and a Thunderbird Turbo Coupe. I always ran heavier oil due to engine heat (glowing turbo/exhaust is not uncommon after running a 2.3 turbo hard) and I remember a cold snap where I didn't get a chance to change the 20W-50 Mobile 1 in my T-Bird. It got down to near zero, and I was pretty shocked that I wasn't all that noticeable on starting. 10W-40 conventional in my normally aspirated Ranger was a totally different story. From that day forward I never put anything but synthetics in anything I owned. I justify the price by leaving it in longer.

There is a link to click in the video where they do 5 bottles all syn oil and same style caps.

Oil really does NOT wear out. It collects dirt and holds it in suspension. The filters "can" do a good job of capturing the bigger pieces but some dirt does pass thru the filters no matter what type you use. We look at our oils color and many times that tells us to change it. Or we watch miles on the oil and then change it. Some Amsoil dealers tell you to change the filter but not the oil. When oil "wears out" its usually has high miles or its contaminated. Think of the cost to change oil in the over the road engines at say 3000 to 5000 miles. If the oil is sampled you can learn what condition it is in. Has the additive package worn out or what is the oil holding on to like metals or anti freeze. Blackstone was what I used every oil change. It got expensive so I have not used them in a few years. Maybe every 6 months is a great way to determine what condition your engine is in. But oil will not wear out. It just gets dirty and we change it...

This was a guys response to changing the oil early on vw diesels. Vw recommends 10k miles.
Tell me what you think.

I've seen and done wear analysis on these engines and it's a fact not a myth.

5,000 mile oil changes were a sure way to kill the PD engine cam and lifters. I have several customers on original cams running 15k oil changes with more than 300k.

Dont believe me?

Wear plot test:
- Pull oil sample before changing oil
- change oil and filter, suction out filter housing, fill with Mobil 1 Turbod Diesel Truck 5w40
- start engine, run for a few minutes, shut-off and sample oil.

Sampling criteria:
- engine hot, running, intervals every 500 miles via the dip stick tube using an oil sample suction kit.

Place each samples data and mileage in a spreadsheet, and note the results.

Wear is computed in PPM per 1k, or you can plot wear in PPM per 500 miles for greater detail.

Run the oil change to 30,000 miles, topping off only when needed.

Prove the oil industry wrong that extended drains result in less wear...

Not sure whats being said there....sorry...

Not sure how that has much to do with cold pour point which was what video was about

Say what...missed it...dont just say it link it

Oops. Might have posted that in the wrong thread.
Basically the guy was saying if you do early oci's, you'll damage the engine more than extending it out longer.

How dat?

Of course he didn't have a explanation.
But he pulled the "if you all knew as much about lubrication as is do.... Yada Yada yada."

Ask and you shall receive

 

[riotwarrior]

He needs a more zecure platform he can load and flip simjltaneously...regardless

Mobil 1 and Amsoil again are the top 2 as previous with wally coming in a bit back for a 3rd spot...

Sweet.

That's why I am not really a believer in spending the extra money on synthetic oils. Yes it's a better oil, and if I had extreme conditions where I needed it, fine. What I don't believe in is the "extended" oil change periods they claim with synthetics. Like was said above, the oil is a vehicle for engine contaminants, and getting those out of the engine is what changing the oil frequently does. And just changing the filter won't do it either, just ask the guys that burn waste motor oil. They filter it and filter it and filter it again. Spin it out and whatever. And they still wear their injection pumps out on the used oil.

I would think IP tolerances are much finer than engine tolerances for bearings piston skirts etc and filtered well with bypass synthetic oil does and has proven to offer effective drain interval increasess over conventional oils based on science with oil analysis.

I would suspect a lesser oil would also prove to have an increased life with decent bypass but how long I do not know. Also the additive and dizpursant packages being different may break down sooner, again I do not know for certain. Oil analysis would prove useful here too.

Maybe @PwrSmoke may have somethi g to offer here.
