#4714239 - 04/02/18 03:18 PM Archoil AR9100 Additive Any Good?

Been reading a bunch about how wonderful Archoil is in late model ford Diesel engines and the nanoborate anti wear additives sound like great stuff especially in high performance/high load engines.

Some of my friends have used it with great success elimiating rough running diesel injector issues.

Always been a little skeptical of most oil additives watching many come and go over the years, but if this stuff is as good as advertised, I'm strongly considering using their oil additive in my 2008 Ferarri built Maserati 4.2l gasoline engine.

Any of you experts have experience one way or the other with Archoil?

Many thanks.

The Archoil additive is tailored for the injection system (that uses high pressure oil to actuate the injectors) in primarily the Ford 6.0 diesel (read 6.oh-no). Although several people swear by it in the 6.0 I don't know that it will do much aside from lighten your wallet in your gas engine over a well formulated Euro Spec engine oil.

Chromedome on powerstrokehelp.com sure swears by it. He is usually pretty reliable but can get a little preachy at times.

FWIW there are many, many previous threads on Archoil, some of which are very long and detailed. You may wish to search for them.

I hear some top fuel dragster mechanics swear by it as well to protect the bottom end.

So far I don't see a down side of trying it but wanted to see if any of the chemical engineers who frequent this site had direct first hand experience or had conducted any lab tests not funded by the manufacturer or their competition.

Every fuel car I've ever had the pleasure or turning a wrench on or talking to those who did got only one thing dumped in it... SAE 70 2-3 gallons depending on the era. We changed it every pass and after the in pit warmup before the pass. It always came out looking like yellow green frothy slime from the fuel dilution. No need to bother with additives when the engine gets 8 new pistons, rings, connections rods, and a full set of rod and main bearings every pass. No additives would have prevented the failures I've seen. Blackened bearings were usually the fault of the tuneup, broken rods and severed blower studs usually the same thing. For a while we had an issue with yanking all of the main studs out of the block.

Been reading this board for many years (without posting any questions) from the searches I've done nearly all the Archoil threads in the past 2 years pertain to how it works in Ford diesel engines or talk about one of their other products (except for the interesting Dutch Coast Guard article).

Was hoping to see if anyone had more current test results over the past few years on AR9100 in gasoline engines.

Thanks Again

The problem with all such additives is that people "swearing" by it, "first hand experience" and testimonials is all you are going to get. You can find various studies on the individual components or purported ingredients, but if you will not find actual and meaningful laboratory tests on the whole additive to either prove or disprove their claims.

The thing is, it's not as if such tests are unknown or impossible to run. You will find too that it's generally the claims are made in such a way that even if the tests were run they wouldn't positively indicate either way (lots of "up to" language).

No, you would find them in the same searches that you've already done. Besides, such tests are beyond the scope of anyone on here that I know.

It will be interesting to see the results without the additive as a comparison. Unfortunately it will be a different oil though? How will that be meaningful?
