Do engine oil additives actually work? (aftermarket ones)

Hey you're back.
So GTL based synthetics are more expensive than other hydrocracked oils at Walmart?

The Walmart branded stuff, not everything else on the shelf.
Oh and āboth carry the same service logo's and special service letters that the engine calls forā as you said?
And itās ālogosā not logoās. I thought you had both a degree in nucular engineering and a law degree from Harvard? Didnāt they teach you proper punctuation at either place?
I have used MMO as an oil additive (replacing 1 quart) as I thought it would help with additional cleaning of a higher milge vehicle . The result was inconclusive ... However I have used Rislone High Mileage (16 oz. bottle) and was happy with the results to clean / cure a sticky valve . *Using a good synthetic oil and oil filter at lower oil change intervaals seems to be the better ply long term for most anything you are trying to cure or improve in an engine .
I use Hyperlube (Polymer Ester) in a small quantity. Most engines don't need a supplement. Interesting thread though. I would digest what Molakule posts.....

Really; I guess I have been incorrectly formulating IC engine oils for the past 30 years.
I tried some Lubeguard Bio-Tech this last go around...

Nah. You been doing right the whole time.
How come the viscosity is so low? Gas? Shearing? Additive is low viscosity ?

The report notes it's not from fuel.
We all know BS fuel estimates
It seems to be a light viscosity and the this motor just about lives @ 7500 RPM. I have a thread with all reports on it in the powersports section. I do question B-S methods of fuel however.

You can get a better idea by finding the virgin FP for the lube and comparing it to what they are showing as I think Blackstone just "wings it". If this is the AMSOIL Marine 10w-40, the FP is 464F, so it has dropped ~80F, which is reasonably significant.
Using a visc calc, let's use a visc for gasoline of 0.550cSt. The visc for your 10w-40 virgin was 14.1cSt:

I end up with 89% 14.1cSt, 11% 0.550cSt to get to where your viscosity ended up so around 10-11% fuel dilution.
a match?
Pretty much, yes. Although back when I ran the test it was a gas flame.
Its what I used in the field ( and a blotter and a nose) before Dexil kits
