oil additives
Funny I haven't seen anyarguments about this on the forum I
KNOW all the arguments for & against, do not use them in our current Kombi & won't - have always used Nulon in the Humber BUT I would
not recommend them, it is personal choice & that is that
HOWEVER I can't argue with this,with our first Kombi a total shitbox with everything that you could possibly find wrong in a Kombi (except for
the heads) which was our training exercise, I was rather dubious about all the strange noises from the motor & the occasional oil warning light
coming on, l had not yet learn't that where I was checkig the oil at home - full on the dipstick was really the low marK!! so shoved a bottle of
Nulon in to extend the engine a bit, all went well until I went to lunch had to go a long way quick & THREW the kombi through a round-about - Oil
light came on & stayed on, there was nowhere to stop & I was going to a shopping centre anyway pull ed over over after 7 ks of heavy stop
start traffic (Old Windsor Road for those in the know!) & checked the oil - way below the low mark - no rattles- thought what the hell &
remembered the original Nulon demo of a Torana doing Sydney Melbourne with o oil in the sump & kept going, the way I felt the motor could blow up
& I would happily walk away- forever- went to Big W & bought 600ml Oil & oil light still would not go out so got a lift back to work &
organised a tow Truck Home, when I got back to the car to await the tow truck 3 Hours later I started the now cool motor still Oil light on & it
sounded like a Bucket OF Bolts (all the motor tolerences had opened up) hoisted the arse end up on the tow & $80 later home, started the to drive
in the back yard - oil light went out, quite motor & 3000 hard kilometers later it was still running strong the tow had primed the pump
interesting--- & true - or in other words if the bottom end
of your motor is crook & you want to keep going just that little bit longer you have nothing to lose except $10.00

basically I wouldn't use them in my engines. The additive manufacturer cannot possibly know how his additive will mix with every single oil, so I
don't see how they make the claims they do. Also the test rigs show at car shows display the benefit of an EP additive, pity there aren't
any Extreme Pressure parts in an engine. You would find EP additives useful in a diff, not an engine.
Or if you want a quick laugh at how funny the oil additives are, read below.
Agreement restricts claims for Slick 50 additive
WASHINGTON (AP) - The manufacturers of Slick 50 auto-engine treatment have agreed not to make false and unsubstantiated claims for the additive.
The Federal Trade Commission gave final approval to the consent agreement with Quaker State and three subsidiaries Tuesday.
In a July 1996 complaint, the FTC said Slick 50's claims that, compared to motor oil alone, it reduces engine wear, lengthens engine life and
provides a host of other benefits were deceptive and unproven.
The agreement bars any claims about the performance and benefits of any engine treatment, oil additive or Slick 50 engine lubricant without sufficient
substantiation.
It also holds open the option that the FTC may seek consumer redress if private class-action suits against the companies currently under litigation do
not result in at least $10 million for consumers. The FTC reserved its right to intervene in any class-action suit to oppose a settlement it believes
is not in the public interest.
At the time the complaint was filed, Slick 50 sold for about $18 a quart and Quaker State claimed to have about 60 percent of the engine treatment
market. The subsidiaries are Blue Coral Inc., based in Cleveland, and Blue Coral-Slick 50 Inc. and Blue Coral-Slick 50 Ltd.
The agreement was the latest in a series of FTC cases involving unsubstantiated claims for automotive additives and high-octane fuels.

I Remember about 30 years ago when Slick 50 had virtually the whole market here it was absolutely horrificly unaffordable & not really trusted at
all, its claims back then were totally over the top! I have heard about Teflon clogging oilways in some cases, as a super tech- dude do you know
anything about this?

well I have never been silly enough to use the additives, especially after my tribology lecturer back at uni told us how crap the additives were.
But that link I posted has some discussion about the teflon building up and clogging oil ways. I certainly think it's possible. My main concern
woulld be if I had an oil filter (type 4's), as there have been reports the teflon coats the oil filter effectly clogging it.
So I wouldn't bother using the "performance enhancing additives".
But if your engine is flogged and blows smoke like there's no tomorrow, additives like stop smoke can be of benefit. stop smoke I have seen used,
and it did work. But making the oil as viscos as honey tends to reduce the changes of oil getting past the piston rings

I used to deliver Pennzoil for the NSW distributer, based at our depot, and I asked the manager who was an industrial chemist if these additive's
were any good, and he said save your money!
Basicly he said the same as what Baja Wes said, and that the oil companys spend millions on R&D to get the best possible formulation for your
engine.
Just use a good quality oil, and that is all your motor needs.

someone told me that the best additive to help the motor was to add an enthusiast to change the oil regularly.Ha Ha

Yes, I agree with the sentiments. I was never interested in the oil additives until I looked into upper cylinder lubricants when the leaded fuel was
phased out. When I bought some they threw in a bottle of their oil additive (claiming all the usual benefits).
I never intended to us it, but my 2L T4 motor is VERY tired at the moment with loud grumblings in the bottom end. I currently suffer from over heating
oil on long trips which leads to low oil pressure (the oil light flickers at idle when the oil is very hot).
It’s now at the stage that even fresh oil has the same problem, so I decided to throw in the oil additive to see what happened.
Well, it made no difference to oil pressure and the oil heats to the same temperature in the same time as usual, despite claims the additive would
improve both. I have also not noticed any power improvement (another claim, but I have no measurements to prove this) or any difference in the noise
from the bottom end.
I plan to try one of the higher viscosity engine oils until I have time to finish re-building a spare motor.
