Also sued because all it contains is mineral oil.
The only oil additive the holds up to its claims is lubegard, and that for transmissions, not engines. (I received all of Lubegard's data and manufacturers recommendations enough to convince me that the transmission stuff is real. Also developed in conjunction with government.)
BTW-speaking of oil analysis- I should get the results of my oil analysis in my 2001 Sentra. First oil change at 30 with Mobil 1, second at 4K, third at 13K and the one I took ath oil analysis at-18+K. I did not change at this sampling-just put on a new filter. Hope its OK bc I put on a $10 K&N filter. I'll post results.
My son has a 1997 Mazda with the notorious CD4E transmission so famous for failure. He naively assumed that when he purchased the vehicle at 30K that the used car dealer had changed the transmission fluid. At 60K it would rev up to about 5000 RPM before it would shift. Then it was very hard. I took it to my Mazda Specialist (20 years with the dealership) They said that one of parts (solenoid?)was worn. The fluid was almost completely black and smelled really burnt. The mechanic completely flushed the tranny fluid and added Lubegard. It immediately worked correctly, and has been smooth for the last year. Total Cost $87.00 vs $2300 for a new tranny. For transmissions, this additive is real.
Increased cost $7-10 from Napa. A no brainer.
STP oil treating products contain olefin copolymer and zinc dialkyldithiophosphate, as does the Walmart Super Tech Oil Treatment. STP 6000 Mile Oil Extender additionally contains Molybdenum, according to the letter they sent me in response to my inquiry. I have used STP products off and on (as needed or desired) for many years, and with success. The gain is in barrier protection and anti-wear characteristics, as well as some of the products boosting viscosity at the same time.

All in all pretty OK. I'm extending this interval. Don't think I will go more than another 3K though.
Any thoughts??
You've had good results with Amsoil in your vehicles, but can you really attribute it to the oil? mrdetailer has had good results with Lubeguard. Maybe Lubeguard is partially or wholly responsible for that success; maybe not.
I have had many samples at the same miles on the oil much worse then yours and engine still strong at 145,000
Silicon is an element, symbol Si, found as oxides and silicates in sand. Hence silicon in oil is dust contamination. This silicon is NOT used for seals.
Silicone is a group of long chained compound with an Si backbone with hydrogen and other groups attached, similar to hydrocarbons, with Si replacing the carbon. This is a large group of compounds, also found in seals and rubberized products.
Thus Silicon and Silicone are NOT synonymous as far as oil analysis is concerned.
And Bottgers, the question for many additives is,"if they do no good, do they do no harm?"
In both cases, product Z is "manufactured" oil that mimics very tight fractions of molecules historically produced in cracking towers in the classic petroleum refining process. I don't see a problem here.
In fact, I see the market place demanding other than outrageous prices for "synthetic" motor oil, and Chevron (I think!) found the way to produce the base oils in a less costly fashion (if we presume the old way was costly rather than just grossly over-priced for huge profit).
As I remember from high school, synthesis is combining something simplier into more complicated. Would it be in chemistry, nuclear physics (fusion = synthesis), or in gnoseology (philosophy of knowledge), where synthesis is oposed to analysis.
On the other hand, words are used less precisely outside of science.
malachy72 Agree! My interest is in getting an engine lubricant that appeals to my own sense of the OPTIMUM, where quality of product and price are the major variables.
I also have full syn in all my transmissions, differentials and transfer case in both vehicles. Switched all fluids in my '94 4WD Toy shortly after purchase with Amsoil products when I sold the stuff. I still think Amsoil makes good products.
My 01 Sentrta(converted to syn as soon as I got it home) oil analysis turned out real well at 5.5K so I spun on a new filter and good to go.
I did though today stick a piece of tygon tubing in the dipstick tube to drain a quart and add a quart of 15W50 SuperSyn. It does have moly and a higher level of zinc than their other oils. I'm curious to see if it will drop milage.
I'm real interested in the full synthetic straight weight full syn made by Shaffer's. It has moly and oil analysis seem to do better than Amsoil and Mobil 1. Pout point is I think -40F-more than good enough. Delvac 1 is also a possibility. We'll see.

I also believe almost any SL oil is quite good and that branding of oil is often a way to get people to lay out extra $$$ for advertising.
For example, within the QS/PZ family, Pennzoil specs. very good indeed, almost up with Chevron. Quaker State specs. a bit worse than the Wal-Mart house brand Super Tech, and Wolf's Head does look like an inferior product. They can sell SuperTech for 79 cents a quart because a good portion of any oil's cost is marketing, plain and simple.
Does anyone remember Kliban, an earlier version of Gary Larson of Far Side fame? An old Kliban cartoon showed a rabbit, [non-permissible content removed] over a conveyer belt dropping pellets. The conveyor belt empties into a box labeled raisins. The caption read "Marketing". If you believe there's "welfare oil", you're buying those raisins.
"I'm past the stage of penny pinching."
when talking about buying synthetic. Do you not believe that you are actually saving money using synthetic? I know some here don't believe that but I have proved it to myself. The real penny pincher with any kind of intelligence and a calculator uses synthetic oil. I will save $300/year in gas and go to get my oil changed 4 less times/yr after switching to Mobil1 full synthetic. These cheaper synthetics have not proven themselves worthy to me yet but I do believe your throwing money away needlessly if you use dino.
That to me is the issue in a nutshell. When the conventional oil ie Chevron SL can go 12-15k with no problem at all, it will be time for me to switch on some cars but not all because of the GM 4178 standard. Even the most ardent admirers of the stuff won't do a 10-12k interval! Seems to me they are putting their money where their mouths are! Who am I to leap where even they fear to go!
