ACES IV additive experiment

ACES IV additive experiment
I'm going to start using this fuel catalyst in my '83 SC and see if it can extend my mileage thru increased lubricity primarily in my cylinders/top end/valve guides. I want to break 300K + miles with the performance and oil usage remaining about the same as it is now.
I've done as much reading as I can and want to give this product a run. I also talked extensively with Brian at BND about my car and circumstances.
I have driven the vehicle 2 thousand miles since purchase a month ago and have a record of the vehicles oil/fuel usage and the motors way of going.
This will be a test of oil/mileage and fuel mileage and seat of the pants.
I'm trying to keep my much less than 20k Porsche much less than 20K and just drive it.
I presently have 217 thousand miles on an unopened motor witha leak down test of between 4-6 psi each @ 215 K miles. The car runs well. Had the 15K svc done at the 215K mark.

The last blurb is from Dave Vizard a guy that I have great respect for as an engine builder/tuner/racer
I have no affiliation with the product or distributors.
I'll periodically update with my 'findings'...

As you dont have a control group or any way of really comparing with a well kept motor with regular oil changes i think it might be tough. Good luck with your testing. Should be a neat hobby. if you want to do it right you would have to do an oil analysis after each change and see how many wear particles are in there and compare to a time you dont use the addative.. its the only real way to tell..

OTOH, if my oil usage stabilizes and remains a constant over the long haul that would be a pretty good inicator of effectiveness (and what I'm hoping for).

Have about 300 miles on the car using the ACES IV product and nothing major to report. There is a much stronger carbon smell in the exhaust so making an assumption that some deposits are being loosened up and expelled.
Talking too the maker he says real results show after about 1000 miles and that equates to better mileage in the short term (better lubricity for the pistons) but the long term advantage is lesser wear on the top end valves and piston rings.
I'm still using 91 oct. (highest avail in Az) but will switch too 89 on my next refill counting on the octane boost of the product.
We'll see.
My purpose is to extend the viable 'life' of my motor and remain at the 600 mp qt. the car ran at when I got it so it is a long term deal.
The one gallon of A IV should last me a year anyway based upon dosage.

In your heat, I'm not sure I'd count on an external octane boost in lieu of the best pump gas you can get. Porsche heads are hemispherical and the spark pattern has a lot of shadow-not the most efficient burn pattern. Hence the shift to twin plugs as displacement and compression increases.
Detonation is just around the corner.

i was wondering about this. I dont know too much about internal combustion dynamics but thought it might be worth discussing. usually dark oil is of course signs of contaminates as the result of combustion. Is there not the possibility that if this stuff is actually effective and removes deposits gaps will increase and oil burning will increase ?

Then start checking oil consumption again.
My leak downs at 214k were all 4-6 psi across all pots....hope that all wasn't carbon sealing everything .

That is very possible and I'd thought about that prior to using it. My plan ( I think I had a plan) was to not worry about consumption fo rthe next 1k miles just top up while this stuff does what it does.

As for fuel additives, I have never heard of the one that you are trying but we haves used Swepco 503 and BG 44K for years on all customer cars with great success---we simply do not have carbon or clogged injector issues on our regularly maintained cars, whether carb'd, MFI, CIS or EFI. DFI engines will need periodic de-carboning of the intake valves as fuel additives will not do that job, but that is another story . . .
As for carbon "sealing everything," that simply does not occur. In fact, excessive carbon buildup will cause excessive leak down due to buildup on valves, and severely under-maintained engines can have carbon build up in the oil control rings and eventually cause excessive blow-by. We are seeing this on the newer Porsche/BMW/Audi engines where the manufacturers recommend the insane 15K-20K oil drain intervals. Modern synthetic oil is great, but it can only keep carbon and other combustion by-products in suspension for so long.
Keep us posted and keep driving your SC!

I've heard the same from a shop owner in Phx. His experience with broken head studs is mosltly on older low mileage cars that were babied. Moisture allowed to sit and degrade the studs.
This stuff is cleaning whatever carbon exists, shows in the oil and you can def 'smell' the carbon in the exhaust (dif than an oil smell)...it also spits black moisture on the first cold start of the day that leaves a residue. I'm using the stuff as an upper cylinder/valve train lubricant but was told it def cleans old carbon deposits too.
No issues with performance, runs fine.

Today I drove quite a way into Phoenix to visit a Porsche specialty shop to check my CO since I've messed with the emissions stuff and to meet the owner.
About 65 dif Porsches there for work and one perfect 356 Convertable.
The owner did the CO and it was on the money, said my motor sounded great (I thought there was some valve clatter- he said no, sounds perfect so very happy).
Aces IV, 218,071 miles. I've added the Carrera oil cooler/fan unit, runs much cooler consistantly (40 miles highway @ 72 mph temp locked at 194 bottom line).
I drove 273 miles (adjusted down for speedo/odo error on my car) since my last check and used 1/3 of a quart. This would equate to 819 miles a quart. Thats an improvement.
This is mostly highway at 3k rpms and some town driving.
Anyways, my oil use is going down not up but some of the variables might be the oil cooler but not sure.
Also decarbonising the valves could provide a better seal.?
Unscientific but still a good deal.

id say to early to tell , so many things can affect it , are you running a spreadsheet ? over 6 months would be a better estimate . Good start tho

I agree. Type of driving, temp etc. I'm keeping a log of miles and usage from the time I began using the stuff.
Could also be partially that the car sat for some months prior to my purchase and I'm driving it almost dailey....when I first got the car I'd have 3 to 4 drips under it overnight after a days driving. Now there is one drip.
I still have a strong carbon smell in the exhaust with no visible smoke.
