Maybe I didn’t read enough. Was he saying don’t add water to motor oil? It must be an additive he’s talking about. I just don’t like thinking that hard. Damn it now my head hurts.

Chuck, people are not often swayed nor educated by data, facts, studies or how expertly those things are presented or how experienced the presenter makes his case. People believe what they NEED to believe in spite of all of it. 

 

People choose their oil and service that way. They base their choice of vehicle on connectivity, cup holders and does it have a lift gate, not the rational of it being a reasonable purchase or the data surrounding the platform. Sales guys can't even tell you anymore the particulars of the engine. People choose there leaders by NEED for some personal relief not some greater good, and their religion the same way. Whatever "tickles their ears". (2 Timothy 4:3) Even the mention of that fact will draw ire. 

 

For every person who will respond the the 'Truth" and use it in wisdom there are fifty thousand that will ignore it and act foolishly. Because? They NEED to. They will make choices based on the needs of their pocketbook (paint example). They will choose based on a NEED to be accepted by some person or crowd they hold in esteem. They will choose to uphold their esteem. They will choose to support a personal belief or give permission to a particular vice. They will choose based on some need to be spiteful, disruptive and hateful. But rarely will they choose base on the truth.

 

There is even an entire subset of people who don't want to 'think' or "Learn'. They want to be told and allow someone else to make decisions for them. They NEED it to be that way. Perhaps the need protects them by giving them a person or a thing to blame....

 

So, no, I really don't.....

To my point of view and the way I look at things in general I would say, I very much agree with your statement even though its very possible that certain comments I have said in regards to certain oil brands ( Mobil for example due to having used it and its former products bought out and eliminated from their lineup ) might make one assume I am blinded by the all mighty Mobil gods !. Its more like posing questions to know if the oil I have in stock in front of me is suitable or NOT for certain applications which as I brought up the old engine/flat tappet issue, something that I don't want to turn a blind eye to and go and ruin engines that could keep on running for the limited use they receive for years as long as I don't do something stupid and put the wrong oil in.  

 

Am I guilty of not running UOA samples much, you bet and yet I have to question the accuracy of the testing as has been talked about that not all labs are created equal in their test procedures and equipment they use and also missing certain tests that could have told a lot more about the oils actual life or used beyond its ability to have protected the engine. 

 

The main gist though to your comment which relates to how one thinks and reacts to information and so on, I think back to these last over 5 years and oh boy, has that ever polarized peoples points of view and how blinded so many are to "the system" shall we call it that forced physically or mentally the population like a bunch of sheep. Some woke up to what was going on while others are still in a hypnotized state. I've probably said too much without trying to say too much, but you probably get the point. Yes there are many out there that still think they can use two quarts of white paint watered down and cover a large red wall when in reality now its a pink wall but themselves and their friends all stand there nodding to each other just to fit in and not go against the crowd as to how wonderful that white wall looks.

So here's a question which I don't believe I had asked, or perhaps I had in a round about way. This premium blue, being that it is an SP rated oil, has it been tested with whatever method is being used to determine if it would pass the LSPI test and actually work without damaging the direct injection L8T or for that matter your 4 cylinder turbo 1/2 ton engine which might be more touchy yet because of the turbo ?. Obviously the oil does not carry the Dexos approval but the fact it is an SP oil, if it could work. As it just so happens you have the perfect test vehicle right in your driveway if the testing has not been done yet

LSPI protection is a requirement in obtaining the SP certification. Valvoline happens to have a lab other blenders use to certify their oils. One of few. Mobil also has their own.

 

The SP certification has a limit on the amount of calcium that can be used, the chemical that has been given credit for causing LSPI. So a new blend that meets the limit and has 'read across' on base oils can get a certification without actual testing if all other requirements have been met. Full testing cost ignorant amounts of money that would strain or break the resources of smaller blenders to this 'read across' is used quite often.

 

I have no direct knowledge which method was used for the product you are asking about. But it is Valvoline....

I do and your missive is Goldie Locks perfect in delivery.  

 

Chuck, do you have your manuals for the equipment in question. I know they are old but they should have some information on the requirements of the oil to use. What I'm saying is work backward from what data you can mine.

No, figured it was common sense to not run an oil with a 2.6-2.7 HTHS in a diesel that makes 300hp/500tq, tows heavy, dumps fuel in the crankcase with regens, and regularly sees oil temps over 250*.

 

BTW, your first comment about warranty…even the AMSOIL 0w20 operates in a grey area without any approvals, OEM or otherwise. So if someone was inclined to go down that road, they might as well go all the way…

Remember, AMSOIL is the only company that I'm aware of that warranties their oil as long as it is used per manufactures recommendations.  They are not in the market to pay for warranty work. So what ever application that AMSOIL states their product is for, you can rest assure it's going to perform better than the rest of the lubricants on the market.

I have most of the manuals as in operators manuals for the listed older engines. Having said that the theme really wouldn't change I expect as per the zddp requirement for the flat tappet engines ?. Cats have been eliminated on some vehicles that would have had them but the Jeeps I listed with the 4.0 engine would have the cats all in place and so its a good question with the one 4.0 that has been running up to this point the Mobil Delvac Elite 222 and if that has caused the cats to start to plug up. I skimmed through that article quick but will go back and read it more closely. 

 

That makes sense as far as a known chemical makeup of an oil that has gone through the rigorous expensive testing and a created limit on calcium in this case, and so basing a formulation to meet a spec by chemical components rather than retesting each and very blended oil out there with the same expensive test. One has to be on the inside to have that knowledge !. 

 

I think back to one of those 95 Chev pickups and that a chain of events lead to the turning of a con rod bearing and that was probably all on me because of listening to those that were selling engine parts as per a comp cam and what lead up to installing that aftermarket cam and the ecm didn't like it and I had a chip programmed for me so it would even run properly and the rev limiter had been set higher and ... hindsight is always 20-20 as I would have done different to solve the original issue had I known what would eventually happen. The reason I bring this all up is that the stock factory untouched engine developed a miss at lower engine speeds and might have been at around 200000 miles and after some talking and testing with mechanics it was felt that there was probably a lifter issue and doing some of my own testing I found an exhaust lifter that was leaking down when turning the engine over by hand. Also it was said through the years that GM had some issues with cams wearing out and so I decided to go full on and replace the cam and of course all the lifters. Upon pulling my factory cam out I was utterly amazed since I was expecting to see noted wear on the cam or the lifter bases. Its not like I work with engines much pulling them apart but had someone taken my cam and wrapped it up into a box and handed it back to me and said it was a new factory GM cam I would have had no reason to think otherwise by looking at the cam lobes themselves. That engine had run on the Elite 222 and the prior 0W-30 that Esso had out for years for most of its life, very few 5W-30 Mobil 1 oil changes. That cam could have run by continuing to use that oil to the end of time. There wasn't even a shiny area on the face or nose of the lobes, the oil had been doing its intended job perfectly for the cam. The one lifter leaking down internally, that I don't know or know how common of an issue that was as the miles accumulate.

So here's a question I will pose and of course there is only so much you would know as to how an engine failure that someone had and then pointed to Amsoil as a "potential" party at fault and how Amsoil the company would handle it ( like lawyers that sue everyone in sight automatically and then sort out who is actually at fault after ) . Lets say it was a GM 6.2 still on warranty and the owner was running Amsoil from since nearly new and then one day the engine locks up as the crank bearings seized, what would Amsoil do in that situation if lets say GM denied warranty because they found out that the engine had been run with Amsoil and does not have the Dexos 1 series 3 official stamp of approval. Now in the states there may be ways of dealing with that through your laws, but here in Canada it could be a very different story. The sad part is that the Amsoil from what I gather will meet that standard so it would be no more its fault as an oil over having used the genuine GM Dexos from the dealer and the engine having failed, just that GM could use that as their easy out to save a few bucks even though its their engine parts manufacturer that is probably the most likely at fault.  

 

By the way Nick I did finally find an Amsoil dealer in town that appears like I can deal easily with after making numerous calls to others that were listed on the Amsoil search form as dealers or store fronts but some were on their way out the door so to speak in ending their Amsoil sales or only brought in very specific items and had zero interest in bringing in anything else. I stopped in at said location which is actually a motorcycle/atv repair shop where I was able to order what I was after and at this point that was some gear oils and Dexron 6 equivalent but did have to prepay for the order as some of the items are not products they use in their shop and I totally understand they would not want to be stuck with unsaleable products. Obviously I paid retail price rather than preferred customer price but he then gets it shipped to his shop and I can pick it up at my convince and don't have to worry about trying to deal with the gong show of shipping out here in this rural area where its a total hassle or even possible to do at all. So figured I would give that method a shot and it helped that I was dealing with the owner of the shop and now I know where my brother can get better oil for his Harley as they definitely stock that air cooled engine oil.

Exxon/Esso Elite was formulated by my mentor at Cummins, Dr Don Carver. He was original formulator of Cummins Premium Blue before it was bought by Valvoline. Elite was exceptional.
