This is a 1997 F150 with a 4.6 Liter V-8. Amsoil Dual Remote by-pass with an SDF 26 and a BE110. I have 9+ quarts capacity. There is 50,000 miles on the engine with 20,000 miles on the oil. I've done 2 ff filter changes with the same by-pass filter still in place.

Oil used is Amsoil Series 2000 0w30

 

I have seen several of these type of oil analysis posts. All state what to me is blah blah blah. This could be because I am not an oil analyst, but if you want to state your case for Amsoil then show us some comparisons. You know, like 34 for iron is really really bad, and 33 is ok.

 

Smithy makes a good point. All of that data is fascinating, except it doesn't mean anything.

 

Well since all I run is Amsoil, maybe some of those folks that use a different kind of oil would be willing to do oil analysis to compare results. Also since not all vehicles are used in the same way will you get comparible results.

For Instance, my truck sits for weeks at a time then it might get driven to wal-mart and back(about 5 miles) then goes back to sitting. This is very hard on an engine. In my sample the Lead numbers are higher than what I have seen, though I suppose that they would be the same or higher with anything else.

Most wear numbers on an oil analysis can be interpreted at ppm per 1000 miles.


Anyone intersted in doing a sample and get a kit for about $20 from various oil analysis labs.

 

Okay lets compare the last three samples. Most recent first with each one being at 10,000 miles and about 1 year. Orginial sample was taken at 30,000 miles on the truck at which time I had no by-pass and used Amsoil 0w30 and an SDF 11 stock filter with no filter changes.

Notice the Silicon was 24 on the first sample, I had a K&N on at that time, when I recieved the 1st sample back from the lab, I immediately through the K&N in the trash!
Secondly, the 1st 2 samples were done at the Oil analylizers facility and the most recent being done though the CTC facility who is on contract with OAI for sampling.

Overall I'm thrilled with the service of the new company. Oil samples cost $18.95 for prepaid shipping. Also I can retrieve my samples online throught the link: http://amsoil.ctclink.com/


As you can tell I'm not a really good candidate for a by-pass filter as I don't really drive the truck alot. Though I can say that since I havn't changed my oil in over 3 years. I'm getting closer to recouping my cost of the system.

The more miles you drive your vehicle the faster you will see the savings of a by-pass filter and synthetic oil. Though extended drains can be done with any oil and a by-pass filter it only makes more sense combining By-pass and synthetics.

 

My confusion with this type of thing has always been the same. Why would someone go through all of this hassle, and worry about the engine failing, just to save three years worth of oil changes? Not meant as a flame, just trying to understand the reasoning?,,,,98

 

Seems to me that it's no hassle at all. Think about it No oil Changes for the life of the vehicle. This is what's possible.

Also I don't have to think about it at all. Once a year I do a sample and change out my filters, top off with fresh oil. No waiting in line, no worries if I want to take a trip, but have 2999 miles on my oil and my truck will blow up 1 mile past that.

Plus I can figure in, that I'm saving money on fuel--which is about 3-5%. I don't have to worry about the price I pay for oil, so I can use the best oil. For me it just makes sense.

Though I'm also a person that doesn't understand why we still make houses out of wood?? Especially with the impending doom of Isabel knocking on my stick home. I just hope it holds together.

 

I see oil changes as an excelent time to check out the rest of the vehicle. Check tire PSI, tranny fluid, add any windshield wiper fluid, check air filter, check battery, etc....... The $24 in oil change might save a tranny or a blown tire one day. I guess its everyones prefference on wut they like for oil. I guess its like tires, some people use high performance ones while others use the cheapest tire they can find and drive 200000 miles on it. Guess it depends on how safe you want to be.

 

ms, thanks for posting your results.

 

Smithy,

I agree, I can't read them either. I have gained some understanding from reading comments. I like to read the comments made by those who have an understanding of what the numbers are and where they should be.

 

You ask a good question IMO. Here's and answer IMO.

1) It's just another mod for our trucks. I't exciting to buy, exciting to install, and exciting to see the results. That's why I'm so excited about it, I have the same setup. I put mine on at 5/31/03 34,250 and today I'm at 39,750.

2) This is more about the by-pass than it is about the oil. Changing the filter on the by-pass if much easier than changing the whole sump. I'll change three filters a year and with it three quarts of oil. It's a remote filter which easy to reach.

3) Test have shown that more oil is better, and I'm running 8 quarts. That's probably why Ford designed a 6 quart sump.

4) Since you only need to drain 3 quarts of oil it is more economical to run an expensive oil like Amsoil. It's a no brainer to pour in the best oil you can find.

5) When you combine a by-pass filter with synthetic oil the wear is barely measurable. True this makes it overkill for engine protection. Still, I like the concept of expecting full hp and compression at 200k even though is not likely I'll drive that far before 2011 when I get my next new truck.

6) The oil in the engine is always clean. There is no last 500 miles driven on dirty oil.

Once it's installed and working, it's a great mod.

 

How much make up oil did you use in 20,000 miles?

 

My truck requires no make-up oil between filter changes.

I did a filter change August of 2002 which took about 2 quarts of make-up oil.

I did another filter change Feb of 02 which took 1 quart(I used a smaller ff filter)

So I guess over 20,000 miles I used about 3-4 quarts.

 

msp,

are you going to change that by-pass filter now? You have an aggressive plan, as you should be changing out 3 quarts a year. Are you going to stick with this plan or change the ff every 6 months?

 

Actually I didn't change anything for the 1st year!

I think that this time I"m just going to change out the by-pass filter. Then maybe in the spring change out the FF filter.

I had been using the SDF 26(the big FF filter) Now I have an SDF 15 which is smaller so I won't have so much makeup oil to replace.

I'm going to try to change 1 or the other out every 6 months or so. As I'm thinking I need to keep the viscosity in check and the Additives in good shape(which they are by the way)
