Magna Flow 4in Exhaust System

remote oil filter kit

I have been using Amsoil 15-40w full synthetic diesel motor oil in my rig for two years and have had no problems so far. There ain't no API circle on the bottle and that bothers me. I was told that it cost about $400. k to get that certification so they did not want to suffer the expense and just rely on word of mouth and extensive advertising instead. Their choice, but $400. k is chump change for a company this size, so I smell something wrong not to mention warrenty implications from auto mfgs. Went into a NAPCO store and saw the Royal Purple oil and the guys there all raved over it. So I called the RP 1-800 # and talked to one of their engineers and asked him about his product. Well of course it is better than anything on the market and there API certified right on the bottle. Well hear it comes the guy said through independent tests that they beat Amsoil in every catagory including the 4 ball stress test by a long shot. By 1/3 less wear spot and the spot was polished after the test. I as I recall I have never seen the Amsoil grafts show RP in their comparisons and by the way they are competitive in price. ( mail order from oil town). API certification gets my vote and makes my warrenty feel better, hear say is just like weight loss pill adds. b:--) I am a retired Exxon guy and RP is in my opinion a superior product because they passed the tests. :-{} Oo. :D
 
badams1,

You have been using this product for two years you say. Just to ease your mind a bit, Amsoil has had the "Full" synthetic 15W-40 Diesel oil on the market since 1982, with no "Donut" on the bottle. They also had a partial synthetic 15W-40 Diesel oil on the market in 1979, and it too did not have the "donut"! Not a BIG deal to me. Their testing is certainly not based on "HEARSAY", but rather extensive lab tests as well as hundreds of field tests, and the products are also tested using the ASTM standards, such as the ASTM D 2270 (Viscosity Index) used for calculating Viscosity Index. Viscosity Index indicates how much a lubricant's viscosity will change according to changes in temperature between 40 C (104 Deg F. ) and 100 C (212 Deg F. ), which roughly define the NORMAL temperature range of most operations.



What does this mean?



The smaller a lubricant's viscosity change as a result of temperature change, the higher that lubricant's Viscosity Index. High Viscosity Index lubricant's protect better in operatons with temperature variations. The Amsoil 15W-40 (AME) Viscosity Index is tested at 164.



Being a retired Exxon employee, you may already know about these ASTM tests.

The amsoil 15w40 is a good oil... spend $15 and do an oil analysis yourself if you really want proof. Delvac 1 is a little bit better but costs quite a bit more.



I agree amsoil should get api certified, and are being plain cheap. It doesn't cost $400k, its more like $25k. Amsoil is a sleazy MLM organization in my opinion, however they do make good oil.
 
speaking of delvac 1

I run the delvac in my sprinter.



I cannot fid it anywhere, even the truck stops don't have it.



Where is a reliable place to purchase it now.
 
badadams, ttreibel's brother John used to be an avid RP user in his '98. 5 CTD and always analyzed the oil religiously. He then switched to Amsoil 2-3 years ago using the 15W40 HDD/Marine oil and continued his sampling regimen. There was enough difference in the sampling results to convince him the Amsoil was the way to go. Maybe he'll get on here and go into it in more detail.



It's always been my belief there is no "right" oil for everyone and that a certain brand may work better for one person and something else is better for another. I've heard some swear by RP and Redline, other think it's low quality inconsistent stuff. One thing for sure. . . when it comes to oil, everyones got an opinion! :D

I'm with VAUGHN, everyone has there own opinion. I remember the first time I was introduced, and convinced about the benefits of synthetic oils. I think the year was 1988, we had just put a large industrial air compressor in, I think it was suppose to draw about 180 amps at 480 V 3 p. When we started it up, it blew the fusses and we could not get it to run at the name plates amp draw. It took somewhere around 225a fuses to run, everything was checked and it was right, just was taken alot more juice then it was suppose to. We were in the maintenance office talking about this odd compressor, and a salesman came in and overheard our conversation. He ask if we could show him the compressor, and we did. After some examination he said he would give us some synthetic compressor oil, and if after the installation, it didn't solve our problem he would eat the cost for the oil. I remember several people laughing at the ideal of "OIL" solving our problem, I didn't think it would work, but I admired the guy's confidence in his product. So we drained the compressor, I think it held about 10 Gallons, and replaced it with the synthetic oil. Before we did this, we took a AMP reading an it was drawing about 220 amps. We started it up, let it run for about 5 minuets, and took another amp reading, the thing was drawing 175 amps. We could not believe it, we put back in the original size fuses, and it ran fine. The only thing we did was change oil, and the oil reduced the friction enough to reduce the drag on the motor. Well I was sold, and the salesman got paid for his oil. As a matter of fact, the company (BORDEN CHEMICALS) WAS SO IMPRESSED THAT THEY SWITCHED OVER THE WHOLE PLACE TO SYNTHETICS. No small job, several 100 thousand dollars to do, but they saw immediate returns, in both reduced electric use and reduced maintenance cost (they on average got twice the life out of there equipment). I have been using synthetics every since. :--)
 
E7mack - getting cold up there in fairfield? ;)



You can get delvac 1 at www.avlube.com . they are out of the columbus area, if you are down that way... . they are competitive price wise and ship quickly... .



Sprinters are sweet!
 
Amsoil has a TECH line. call and ask about the rating and difference between it and ask about comparison of RP and such. Post their reply!
 
There was a fairly lively thead a while back about Amsoil and API certification. One of the Amsoil dealers got a reading on the issue straight from Amsoil. As I remember it, the reason that they do not have API certification on their full synthetic is becasue it does not fully comply with the API spec because of the additive package used for the extended drain intervals.



Amsoil does make a synthetic blend that does meet the API specs, but is not recommended for the looooong extended drain intervals of the full synthetic. Here is a link to the product. With API certification on this oil, you might be more at ease using it.

Look up the Royal Purple website (on the bottle), their testing was just as comprehensive and they beat Amsoil and still included API certification. The engineer that I spoke to on the phone (and that number is also on the bottle) said that the premium grade synthetic oils that were used in the comparisons are Amsoil. API is scientific documented testing data that is the only USA acceptable standard that is required for our mfg. warranties. Then there are the specified dodge product nunbers that you will find require an API rated product to match. If you call oil companies and ask them if their product matches the chrysler specs. and get a fax to that answer you are covered in writting to choose the alternate product. Yes synthetic's are better no doubt but all that I am saying is where's the beef? No meatball guys, "come on". Amsoil is too good for API testing? You have got to be kidding! You are right opinions are like a-- ------ and rverybodys got one but API data is the standard and it is a much higer standard than opinons. This is not the Fuller Brush man and I don't guarantee that you will lose 50 lbs in 30 days. Lets cut the c---p! This is not an opinion and I have all of the Amsoil data that has ever been published in a stack 2" thick but a lot of it does not meet API period! Are we having fun yet? Oo.
 
Here is how Amsoil answered the question.



"How Does AMSOIL INC. Ensure Their Products Meet Or Exceed The Minimum Specifications Of The Tests Required For API Licensing?"



First, AMSOIL INC. works closely with major additive companies to select the top performing, and usually most expensive, passenger car and heavy duty diesel motor oil additives. These additives have already passed all of the API licensing requirements in a petroleum or synthetic based formulation. Then we work with the additive company to maximize the amount of additive used and to boost the additive package in selected performance areas to achieve an optimum performing additive package for reduced wear and extended drain intervals. This is unlike the vast majority of companies who, because additives are expensive, use the minimum amount of the least expensive additives required to meet the minimum API requirements.



We then utilize a blend of synthetic basestocks with known performance characteristics as a replacement for the petroleum basestocks to optimize performance in areas of lubricity, volatility, viscosity index, oxidation and nitration resistance, pour points, flash points, deposit control, soot handling, emissions, etc. We also will utilize a highly shear stable V. I. improver to ensure viscosity retention throughout extended drain intervals. This replaces the inexpensive and less shear stable V. I. improver used in the API licensed petroleum formula. We do laboratory bench tests before running field tests to verify the superiority of the synthetic formula in actual use. We also continue to monitor the performance of the oil through close scrutiny of tens of thousands of oil analysis tests per year across a wide variety of vehicles all around North America and the World. AMSOIL INC. has been collecting used synthetic oil samples from passenger cars since 1982. No other oil company has such a vast data base of the performance of synthetic lubricants over extended drain intervals.



I have seen $0. 49 cent oils with API certification! I certainly wouldn't want to use one however. Can you imagine what the oil company has invested in a can of $0. 49 cent oil? I can!



As someone already said; "Everyone has an opinion!" That's what makes the world turn. NO ONE,especially me, is trying to change your opinions.

Delvac I.

Works for me. I've got other stuff to ponder without wasting time stressing over what's in the crankcase. :D



Lightman E300 --->



I notice you are from Sarasota. I get Delvac I from Bradenton Fuel Oil, Inc. 6116 21st St. E, Bradenton 34203. 941-739-2643 941-755-2636 Fax: 941-755-8142. You have to buy a case - 4 gallons. Price was $21. 15/gal. , $84. 60/case + 5-6 bucks tax. Not a bad deal, eh? BTW, if you're gonna go there call them first and ask for directions otherwise you'll never find the place unless you know where Donzi is in B'ton - they're right across the street.
 
Well folks - amsoil is a multilevel marketing company. Amsoilman, do you really think you're getting the straight story from them when they're MARKETING TO YOU as well? Think about that before you answer. I love how amsoil dealers believe everything corporate feeds them. For a while some folks said that amsoil contained too much ZDDP anti-wear additive to become api certified, but I believe that was just Series 3k, and I believe moreover that amsoil is just cheap and doesn't want to be locked into their formulation...



RT66 - thanks ... they used to be called Ryan Oil, on old 301 (15th), but moved... if those are the same ppl. I just order from avlube because after shipping and no tax, the price always turns out to be just about the same, and it saves me the trip of going to get it... Plus avlube has primrose(emulsifying) fuel additives and other good stuff that I generally order at the same time. Thanks for the info tho, and maybe I'll see you around sometime!
 
The extended drain and alternate filtration along with sample testing is all supposed to offset the extra cost of synthetic oil prices that we all spend hundreds of $$ on. Hay! API certified synthetic oil is worth the price(most brands-"opinions") so just use it according to the warranty requirements and count it worth it and the right thing to do. No body is taking advantage of anyone here it is all proper well thought out maintenance procedure. Use the best Cummins/Dodge flull flow filter and a good API diesel certified premium synthetic oil after break in and change it at 7500 miles. It's worth the price and forget about something for nothing. Do you really think that all of the petroleum engineers are stupid and corrupt? Oil sampling, $300. bypass filters, why do all of that stuff. It just give's D/C an issue if some thing happens to your engine. These Cummins engines are tougher that a sledge hammer and following their maintenance recommendations is the right thing to do and it is worth the price, besides I want a new truck every 300k miles or so anyway. :D I am not selling oil here like some of my contempories but I used to make it so go ahead and rant all you want but this is not rocket science as some would have you to beleive. I will admit that catagory 4 and 5 blendstocks and propriotary additive packages do make a big difference in quality but all of this data is easily accessed if you know where to look. I ain't lost a lb. yet darn it. {}
 
LightmanE300 - Yep, Ryan Oil... that's what they used to be. Now that you mention it I think I'd rather have it delivered to my door, too. Even if it costs a few bucks more. Time is $$$ Thanks.



badams - What you said. :)

This Amsoil and the API issue is getting old. If there was just one person who could say they had an oil related failure or was denied warranty while using Amsoil it would matter.

No one has ever claimed that here.



BTW I use Delo.
 
Oh MY GOD, you use valvoline??? When I bought a ford E250 work van, attached to the steering wheel in big bold print, with a yellow backgroud it read. DO NOT USE VALVOLINE MOTOR OIL PRODUCTS IN THIS VEHICLE, THERE USE WILL VOID MANUFACTURERS WARRANTY! I couldn't believe it , I thought Ford and Valvoline were kind of like partners. Hell they both sponsor Mark Martin, and are on the sides of his ford. I still have the tag.
 
royal purple for me!



i also have all the 2"thick of amsoil literature. and i still went with royal purple(API certified and lots of moylbdnuem). i dont like how amsoil sells itself. just put it on the shelf and i might by it. my buddy was running amsoil did not like it. (dont know why) but is running royal purple.



notice that turbo seems the spool a little better vs. rotella.





i any turbo charged vehicle i think syns should be used.



amsoil can say what they want if they dont have api cert's i will not use their products. no body likes a rebel.
