From what I've read about Wal-Mart SuperTech oil, it's good oil but you may be changing brands with every oil change because Walmart as usual goes with the lowest bidder.
Some people feel it's best to pick one brand and stick to it because the additive package varies with each brand and some brands' additives aren't compatible with others. You never get all the oil out in a change and you might not get the same brand twice when it says Walmart on it.

I suspect you could run without an air filter and have relatively clean oil for 5k. Leave it in for 15 or 20k and then check it. I run my oil that long and haven't seen over 3 ppm silicon. I suspect I'd see 1 ppm for 5k. This is with a stock (Dodge) filter. So I'd say yes your filter is doing a lousy job compared to the stock filter.

Maybe someone can explain how I can take a motified 400ex worth about $12,000 with an open air box and run it in the dustiest conditions on a motocross track, filter " K&N" looks like you took it off and rolled it in dirt , and never have any dust, dirt or anything on the other side, clean as a whistle. I highly doubt our trucks take more abuse than moidified single cyl eng turning 7-9,000 rpm . Dirt is dirt I dont think if I had a k&n on my truck that it is going too see as much dirt as my racer.

But, I KNOW the CUMMINS needs WAY more air than your dirtbike. Lets compare apples to apples instead of apples to dirtbikes.

Yes.
Idling a Cummins for 3 minutes to let the turbo cool takes in as much air as running around the motorcross track 3 times.

Mobil 1 filter and Rotella T oil.

I can understand walmart oil and filters in a 1978 toyota corolla, but **** these engines get a heavy load and are expensive to service. Not worth it.

"apples to apples" K&N VS K&N , dusty motocross track vs hwy driving? Your right no comparison.

Single cylinder naturally aspirated engine vs a TURBOCHARGED 6 cylinder with way more compression and air requirements. An engine that hold at most 3 quarts of oil, more like 2 quarts vs an engine that holds 3 gallons.

Ive decided that Im just not going to bother posting in K&N threads...just like I do in the oil threads. Its your TRUCK

Now look what you did Dorkweed ! Mopar filter and Delvac for me, just like anything else, you get what ya pay for.

infidel

Well then a K&N costs more than a Mopar

Sorry Infidel, I was referring to the oil filter not the air filter. My truck has an All Fired Engineers drop-in and Torque tube on it.
