Synthetic Rotella

Dargo.... I am curious... have you had any experience with Mercedes, BMW, Volvo, or any of the other high end cars? Is it mostly the newer cars or does this problem go back a decade to 1995????? Anything older than that??

I understand. Thanks for the reply. /forums/images/graemlins/smile.gif

Dargo,

I would be interested in the pics, what kind of oil used, the change interval , and the type of driving.

I would have to believe if this was happening than the motors were way over 3k using Dino.

Most dealers recommend 3k or 4 months (which ever comes first) no mater what the book says.

You don't need to be manufacturer specific. That doesn't really mater. Just generally if you think the oil was actually changed or not.

I would love to see analysis results on the used oil.

Here is a pic I got from an inspection today. The owner used Quaker State and claimed to always change his oil every 6 months or 6000 miles without fail.

Conventional oil has been all we have had for decades and has worked well. Whether it doesn't keep up with the current demands, or it is a mistake to not change it every 3 to 4 thousand miles. Either way, when there is too much time between changes of conventional oil, this is what you get. Now, you don't think a person would possibly lie to me and not tell me about missing an oil change or something, do you...? /forums/images/graemlins/smirk.gif

Looking at the last Pic posted by Dargo That waffle iron is a windage device.


Dargo,

Thanks for the pix. Maybe we should start a picture thread for blown up of otherwise wrecked engines, transmissions, and drive lines etc. At our plant we have a whole display of broken components, each with a story.

Now what do I think the average joe would do if he just cooked his motor???? After running 6k or 6 months on dino. O/K was it 6k or was it 6 months.
Fat chance of anyone in that situation coming clean.

The only car that I know of that gets it's oil changed every 6 months at low mileage is my grandmothers, because I do it. With mobil 1. Yes her neighbors did tell her that I was ripping her off because I charge her $25 to change her oil with mobil 1 and a Pure One filter. She set them straight in a hurry (My gran is great) /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

'The owner used Quaker State "

That explains it right there.

The 6 months in kind of long on a petro oil. The 6k is fine since 99% of manuals state like 5 to 7.5K mile miles for a drain.

I have used a 100% synthetic since 1994 and works well. All I will say is, get the oil tested since no 2 motors are 100% the same.

slowrev, you know, I don't have any stats to back up this statement, but I don't like Quaker State either. That sounds bad since I'm a "stats" guy, but for some reason I just don't care for Quaker State. Maybe in my minds eye, I've seen too many pics like the last one and have the Quaker State name associated with it? /forums/images/graemlins/confused.gif Yes, I looked, I don't have any stats against Quaker State; just a feel.

A neighbor bought a new diesel Mercedes in '81 and I bought a new Isuzu diesel. Quaker State was one of several oils recommended at that time by brand name in the Mercedes owners manual; used to have the "CC/CD" rating, and that's when I started using it. Of course, after a few years, we went back to gasoline vehicles, but I stayed with the Quaker State oil in everything until I got a diesel Kubota tractor. I noticed Quaker State no longer had the diesel API rating and I called and talked to one of their engineers who told me it would work just fine in a diesel, but would need to be changed more frequently. So I changed to Delo 400 for the tractors, but kept using Quaker State in cars and pickups until 2 years ago. Now I haven't racked up real high mileage on my vehicles, compared to some; 158k on the Isuzu, 106k on a Ford Escort, only 60k on a 454 Chevy one ton pulling a 35' fifth-wheel, about 40k on a 460 Ford engine in a 40' motorhome, etc., and to make matters worse, I used nothing but Fram oil filters during that time. /forums/images/graemlins/wink.gif Of course, I have always changed oil & filter every 3k miles.

Now maybe I wasn't using the best oil & filters, but I never had a head or oil pan removed from any of those vehicles, never had an oil burner, and never had an engine failure. So I guess Quaker State wasn't too bad. /forums/images/graemlins/wink.gif
