[QUOTE=redassag00;1940682]WalMart Oil filters are made my Champion Labs (not the same ppl that make Champion Spark plugs).

Champion also makes the Oil Filters for STP, ACDelco, Bosch, Mobil 1 and K&N.

As far as Supertech oil, I doubt that it was causing your issues. Supertech oil, like all other oil you can buy at wal mart or your FLAPS, has to carry the API Diesel Rating of CI4. I dont see how this oil could cause your problems.

Did you save some of the old oil to send to Blackstone Labs for analysis to

What the heck is that little film with the lawn mower all about?

Now I didn't see this as a slam to the south. I saw it as a statement that the ones in the south are not creepy, which I took as a compliment.

first off, why would place cheap recycled wal's martz oil, it the worst product that ever placed in the automobile section, especially IN A MERCEDES BENZ!!!!! It has 0 capability to handle soot!!!!

Thats what it was ment to be.

When we get our project 300SD up and running it is getting an initial fill with "Coastal" dino oil from Autozone. We're going to run it maybe 30-45 mins of driving with that, then we're switching it over to synthetic Rotella (same day) and changing the filter again....we're looking at it as a "pre-flush" to get any junk in the engine out that may have gone in there.

The "coastal" stuff is certified diesel oil 15w40.....and its about $10 a gallon....since we're running it less than an hour....it shouldn't matter. :D

I just got a 1976 240D the oil was black just my other cars. I drained the engine oil and oil cooler over night to get everything out. I put in Valvoline’s Premium Blue diesel 15w/40. Several days later the oil is still clear. http://www.valvoline.com/pages/products/product_detail.asp?product=112
I have allways liked Valvoline oil I got on sale at Advanced auto parts.
The engine is vert quiet now.

I don't use dino oil, it gets way too thick when it is cold here. Synthetic is better. Ut oh....oil thread! :D ;)

Valvoline Premium Blue...

I noticed in AutoZone the other day that Cummins endorses it and recommends it for their engines.

That's a strong statement about something. I don't know too many people driving diesels and into technology/mechanical things who don't have a high regard for Cummin's diesel engines.

I wonder what that stuff is like.

Just perused the oil section at WalMart.
 

The Super Tech branded stuff was marked(obscurely) as an "Ashland Oil" product. I know nothing about Ashland other than their coal exploits in Kentucky. Just FYI.

I wouldn't be surprised if numerous suppliers fill Super Tech bottles depending on which masochistic company submits most readilly to WalMart's desire to whip any given market into complete submission.

I hereby offer an oath to you all that I will not get into the detrimental impact of WalMart's business practices on this board. There's not enough time or bandwidth to choke it all out.

I use Rotella exclusively in all my Diesel Benzes. The gasser gets whatever is on the menu since it burns enough, and gets topped up enough, to always show honey clean oil on the dipstick. Anyone want to grant me the time to change out the valve guide seals on a M103?

I tend to buy my oil at walmart only because they have the best price....however, I only buy Rotella Synthetic.

Walmart is a long ways from where I live, so if I am in need of oil and happen to be at autozone, I'll pay the extra $1.60 a gallon and get it there.

Autozone has been running an amazing deal right now on Mobil 1, you get 5qts of oil and a Mobil 1 filter (essentially the best filter out there) for $27....I bought enough to do my uncle's car, sister's car, and wife's car. None of them drive enough to exceed one oil change per year.

Minivan and uncle's cavalier get Mobil 1 5w30 Synthetic....my wife's Rav has been getting the 0w30 high efficiency stuff...it actually did gain us 2-3mpg almost immediately. Amazing!

My car has used Rotella since new, according to P.O's. I have about 4 gallons of Dino Rotella left, after that is used up I'll probably switch to Synthetic rotella. At 128k miles it's probably a good idea.

They probably just thinned some crude with gasoline to get the viscosity right :D

Just kidding, but your story does make me wonder if lower viscosity fractions were getting cooked out and burned off in these blowby machines of ours. Of course, if you have one of those rare no-blowby engines, then that theory is dead :)

I like the Shell Rotella 15W-40. It seems to make the engine quieter and it doesn't burn off nearly as quick :P

As for Walmart... I shop there. I'm not ashamed of it. I *always* make use of my CCW permit when I go there due to the other customers but people are generally friendly right? :D

The MB has replaced my Furd as my "Walmart" car as of late :o

Ever since I fixed most of the major leaks on my engine, it doesn't really lose or burn anything between the 4,000ish mile intervals I run the oil. The most I've had to add in that time period (on Rotella synthetic) was maybe 1/3 a quart. Thats it!

yeah my engine has no blow by its amazing, but its because the engine was recently rebuilt maybie 20k miles ago.

Ive been running it on that same mix of atf/synthetic to try and clean everything up. seems to be running fine with that mix so far Im going to switch to rotella or something and never use that stuff again, it was only endorsed for mack trucks (or something like that) they called it "universal" oil. It was 8.93$ a gallon, and mobile 1 delvac or rotella costs 9.50 its not worth it.
