Filtering oil externally

[clemsonfor]

Where can I get a mobil1 oil and filter change for $30? 15 quarts plus of oil.
I've been using Rotella T6 at about $23.76/gallon w/ tax and the truck uses about 4 gallons with me rounding that to $100.


The regular filter only goes down to 20 microns, and I guess if you don't plan on keeping the vehicle long it's ok.

Well not for a 7.3 PSD or anything but i can at least a few weeks ago, it may be over now (special that is) you could get a FIVE qt jug of Mobil 1 and filter for like $29.95. Its the same way will all oil change special's they dont cater to those 5% of passenger vehicles that hold more than 5 qts.

My answer still stands. I would get the oil change special and 2 additional jugs from walmart for like $25/peice. That would make your oil change $80. I would change it once a year and be done with it. You were also talking about a TDI so i really was talking about it.

If you have one failure do to prolonging oil changes all savings will be wiped.

Very few, actually no people i know that do "too frequent" oil changes have ever had an oil related failure, regardless of brand of oil.

Post you vin numbers, that way it can protect folks from buying your vehicles when you deal them.

It's not so much the cost of the oil. It's all the rest and the work involved. I've 2 7.3's and a TDI that can really use the fine filtering to extend their life beyond mine. One system would work for all. The installation alone in the TDI is a bear because of the cramped engine compartment.

And if I can readily have my oil interval at 20,000 miles that would mean 1/4 the cost of oil, which 15 quarts ran about $100. Blackstone only costs about $25.

Reading some of the reports on bypass filters it seem that filtering down to 2 microns is very effective in keeping all the engines running better.

Without spending a bunch of time researching these bypass filter systems, and seeing just what you guys are talking about, I thought I would say something about the one part i read concerning pumping out the oil pan via the dipstick port, filtering it, and replacing it. I would be concerned that the oil deposits left on the bottom of the oil pan would pose a problem. What might not be picked up during a oil pump out might be shaken up and stirred into the mix while driving and pumped thru the engine. A continuous filtering might be better, but much more expensive, unless it is a simple oil line to the firewall mounted oil filter like I had on a p/u years ago. 3 oil filters every oil change wasn't cheap, but the oil did stay cleaner for longer (visibly cleaner). Don't know what th'at did for the additives but I didn't change the oil as frequently. Sold the truck, so if there was a problem, it became somebody else's problem. (a problem I would gladly take back, since it was a 1955 Chevy Cameo)

I was involved with a test of a synthetic oil in an N14, we installed spinner filters and an oil drain hose so we could fill the oil sample bottle without draining the oil or using the vacuum system Cat uses. when the N14's came out they had an injector problem they did not work, we were in the engines quite a bit every week and there were twelve engines involved 6 got the synthetic, 6 got Delo 400. after a very short time the engines with the synthetic were full of a black jelly, we did main bearings at 200,000 Kilometers the first go round, and at 250,000 after that.
When the trucks had about 500,000 K they did the cost analysis, when the costs of the oil analysis and the fact the oil usage was higher with the synthetics, I had kept all the bearings tapped together with WO numbers on them I asked everyone to write down the 6 sets of bearings that were in the best shape. They wrote down the WO #s the company rep from the synthetic oil company was there and precipitated. These trucks worked 22 hours a day two 11 hour trips over 2 mountain ranges pulling 144,000 lbs of chips.
When the chose the best bearing sets I read out the number that had used the Delo 400, not one person had chosen a set I did not read out. Every engine was converted to Delo 400 when the standard oil change intervals came up, a gallon of ATF was added 1/2 hour before they came in to the shop for the oil change to clean them out.
I like the use of a bypass oil system, personally I change my oil early, and use Shell Rotella 15/40 Dyno. I do not have a bypass filter system.

He is still using a standard spin on factory filter. So i guess he figures any small amout of oil there will just be filterd by OE filter.

Its kind of like doing a ATF change you only get the 4-5 qts in the pan and the filter, the rest is old, but do them enough you will dilute the old with enough new fluid to "renew" it.

And that is the best way of doing it. If you want to kill a trans, powerflush will take care of that.

I don't know if this covers the question, but I don't think you will get decent results by pumping the oil out and back in. I think a light duty by pass system filters 25-50 gallons an hr. So I think the only way you could remotely filter oil is to put it into a sump and pump it for hours or days under filtration. Not cost effective I would think...

This is really not a issue. Been done this way for 50 years in marine applications and stationary generators. Its also seen on some imports with no drain plug.

At what micron level do the filters start removing the additives?

Filters cannot remove additives, those are at the molecular level.

RE:removing oil thru dipstick
It seems to be quite common on Jetta TDI's, especially for those peeps who have put on a bellypan for protection.
