Amsoil vs. Delo 400

More on the war

To follow up:

I don't recall exactly which Amsoil fluids I used, But I did use them throughout my truck - front end, rear-end, x-fer, transmission, engine. That is when I saw the MPG increase.



Gary - keep on speaking the truth! When I took statistics in college, the main idea was that all statistics can be "twisted" and still be valid - so can every study on oil.



Pictures of the inside of engines, 4 ball wear test, engines running with no oil at all, etc, all don't mean a thing to me anymore. I know that my rear end produced more metal flakes running amsoil than it has with Mopar or Lubrication Engineers Inc. products, and it also had the grinding problem. I know that my oil analyis showed higher levels of wear metals with amsoil than with delo - even with the amsoil bypass filter installed. I know that when I put the amsoil air filter in, the next oil sample came back with elevated silicon levels and a note to check the air induction system and change the oil immediately. I had no air problems before or since I trashed the amsoil air filter - and NO there was not a leak in the system. The air filter problem alone was enough for me to boycott amsoil.



Bottom line - do what you want, it's your truck. Take advice, consider the source - it is hard to know the source if you only see their post on a wab site. Remember, all companies say they have the best product, all test studies seem to be "independant", and nobody knows everything - and if they did, they could not put it in a post here.



Good Luck

draymorris: I was hoping to find out which products were used, where, to see if they were the recommended product for use in the proper application. Alternatively, if the wrong product was used in a given application. However, since you "don't recall" it makes it impossible to have a detailed and intelligent discussion. You obviously feel strongly about your experiences you had with Amsoil. It is just a shame that we can not discuss the particulars of what lead to you opinion.

There is a reason why Amsoil refuses to get their best oils API certified, I think maybe the post above yours may be one very big reason why.



Delo for break in, Royal Purple for life!

Good Luck

Sorry to hear you had such a bad experience with the Amsoil brand lubes... ... ... ... ... ... . all of them you used! They must have had you spotted.



I on the other hand, have been very happy with them, and I've used them now for some 25 years.

In all of my 70 years, I have found there are some things that work for us, and others that don't. And that is OK! Use what works for you, and be happy!

"Here is a picture of a bearing from an engine, (won't say what kind) after 226,000 miles and 15,000 mile drain intervals, NO BY-PASS, just regular "off the shelf filters". This is real world"



WAYNE, you're a great guy, and I love and respect you and your integrity - but as we BOTH know, one tree doesn't make a forest - and just because your neighbors Ford blows up at only 100 miles doesn't mean ALL Fords are junk and destined for an early grave. Just because MY Dodge gets 23 MPG doesn't mean ALL Dodges everywhere will do the same, etc. , etc.



Your examples are fine - but as I tried to make clear, my claim was based NOT upon a single - or a selected FEW - examples, but rather on 10+ years of interested observation of posted oil analysis samples provided by various brand oil users across several major diesel boards, SOME with bypass filtration, but MOST without.



All characteristics considered, synthetics are UNDOUBTEDLY the best and greatest for our engines and drivetrains, especially in extreme service and climates - but I stand by my own posted comments and observations...



Peace...

Gary,

You have to admit the pictures I posted show some very good results! The red rubber gasket was even very flexible as well. And just as a reminder gary, all Amsoil's claims are based on millions of miles of oil analysis, and 32 years in the synthetic oil business.



And I am at piece

NOT to be a wiseguy, Vaughn- but how many decently serviced 325,000 mile engines using Amsoil have you seen to base such a comparison on?

Hey Gary, I wasn't implying a comparison to Amsoil using my '96 as an example, just stating the Delo 400 did well on my truck.



What you say is true that wear metals will drop naturally as an engine wears in, however mine had leveled out fairly well at about 15,000 then dropped considerably as soon as I went to the Amsoil. It then stayed fairly level throughout the remaining 70k I had the truck except it went up when I tried Amsoil 5W30 once. Sometime I'll have to dig up the reports and give exact numbers but they're buried somewhere in my stuff to put away after moving.

Oils used

OK - I pulled the file and found one receipt because the rest are stored in last years tax files and it is not worth the time to go dig it out.

front end, rear end - 75-90 item TGR01 is a sure thing. The rest of the lubes are what Amsoil recommended and I beleive that it was 15 - 40 in the engine(the deisel/marine stuff) ATF in the x-fer, and some 40 weight in the trans.



Either way between the oil analysis, showing higher wear metals with the normal air filter, the analysis showing silicon with Amsoils wonderful air filter, and the grinding in the rear end and higher amounts of metal flakes(which I saved in the file) - I will never use another Amsoil product.



Wayne - sorry to hit your business directly, but these are true experiences. Sure, I use my truck harder than most. Most people driving these will never gross heavy weights and go thousands of miles, nor will they keep their trucks up to a point that added engine wear my shown during a rebuild. Just because an engine is clean does not mean that is lubed well, it just mean the stuff in the engine doesn't stick to metal.



As said before, "peace", and no personal attack is intended.

Well, I've been reading this thread from the start, and have to give you my experience with Amsoil. I've been using Amsoil since 1973, in everything from a 3 hp B&S lawn mower to a 350 hp Versatile farm tractor, and have had nothing but good experience with it. I deliver new RV's from fact. to dlrs. all over US and farm when I'm not towing. (10+yrs now) Have had it in 3 Dodge trks. , a 1996 V-10 2500 w/5spd, that I ran for 330K+ mi. (they wouldn't let us use diesel till Dec. 1999, and had to do a valve job at 182K, had to replace all the exh. valves) a 2000 3500 w/ 6spd. , which I ran for 227K+mi. , and now have 221K mi. on my 2003 3500 dually w/6 spd. I used the BMK-15 bypass on the first two, and went to just the bypass on the 03 because of mounting space problems. My 96 V-10 would use a qt. every 8-10K when I sold it. I had to change the oil about 35K on it cause of the exh. headers I had on it, it got so hot under the hood, it would cause the oil to oxidise, and samples said to change. BTW I sample my oil every 8-10K when I change a filter. I change the full flow filter every 8-10K, and change both the next 8-10K. I changed to synthetic on all 3 between 6-8K. I also used the Amsoil air filter on all 3 with no problems at all. I'm not saying Amsoil is the best, but with my experience with it, there is no way I will change. If I used dino I would spend more time on the lift changing oil than I do fueling up! I don't know if I gained any fuel mileage with the Amsoil, cause I changed to it before I got a check on my mileage. Right now I get from 19 to 23 mpg. running empty, I hardly ever check my mileage loaded cause one trip I may be towing a 30' 5er and the next will be a 40', and one trip I may have a tail wind, and the next a 40mph head or side wind. You just have to use the oil you are satisfied with, I'll keep using the Amsoil till I have some problems!!

Sorry this was so long, but I just had to get my . 02c worth in.

BTW I just returned from a trip towing a 36' toy hauler 5th wheeler 4K+ miles, have 30K+ mi. on oil, and it is 1/8 " below the full mark on the dip stick. I usually change oil at 50K to 60K, I have ran it 99K, and sample came back that it was OK to keep on running it. That was on the 00.

" If I used dino I would spend more time on the lift changing oil than I do fueling up!"



I had planned to stay clear of this thread for a while - but there it is AGAIN!



That constantly resurfacing FALSE notion that you can only employ extended drain intervals with SYNTHETICS...



That just AIN'T so! especially if a decent bypass filter is also in use. Most ANY of the better brand oils will go 10K+ miles in heavy use, and with a good bypass filter, 20K is no sweat.



https://www.turbodieselregister.com/forums/showthread.php?t=109166



This whole erroneous notion that only synthetics are capable of extended usage was started by users and sellers of those synthetics, as a work-around of the higher price of synthetics - "why shucks Rube, even tho this here "Snot-Slippery" lube IS 4 times the cost of a good dino oil, ya can run the stuff FOREVER, and NEVER hafta change - why this stuff will actually SAVE ya money over the next 20 years with no oil changes needed, ever!"



Yeah, you CAN run extended drains with synthetics, JUST LIKE you can with dino-based lubes! :-laf :-laf

 

[yogibear]

WHERE did I say that you could ONLY use extended drain intervals with SYNTHETICS?? THATSnot in my post RUBE!! :-laf :-laf :-laf

No offense buddy but you seem to have a chip on your shoulder. As to extended drains and synthetic vs dino oils, I have read many posts and followers of synthetic oil users going for hundreds of thousands of miles without changing the oil out. I am currently at 48+ thousand miles on Amsoil with analysis and plan on running it many more miles. I have read a few second hand reports of long term dino oils but nowhere near the number of synthetic.

Am I missing something? Even the test you did was not for hundreds of thousands of miles. I mean no disrespect and I would try dino oil extended drains but in my mind when attempting to run as many as 100,000 miles on an oil the extra cost of synthetic would not be that high. At my current pace of adding oil at filter changes I should be using around 26-28 quarts or around 120 dollars. Dino would be cheaper but spread out over 4-5 years in my case the price is cheap.
