Slick 50

[TiMiX]

Hi all, when i was looking to buy my Gen 6 Celica GT quite a few peaple said they

ran slick 50 in their engines which put me off alittle as i'v heard bad things about

it when used over long periods

quote:

Blue Corral, the manufacturers of the Slick 50 engine oil additive, have been banned by the Federal Trade Commission from making claims about reduced engine wear, increased fuel economy and lower running temperatures in it's advertising in America. The Federal Commission found the company's claims of increased performance and reduced wear were unsubstantiated, and Blue Corral has agreed to pay upwards of $20M in damages to affected customers.

But now i know you need to rev these engines to 7k to get them to peek power

i'm thinking twice as i want to make sure it has the best protection

Dude going by that link i would stick to good high quality oil, part of full synthetic for full protection. i use Castrol magnatec.... works great for me and i'm usually driving in to the red, only to the speed limit of course.....

toyota oil filters for the gen 6 have a built in valve which only allows the oil to flow back into the sump as it cools . chances are a warm engine still has 2 thirds of its oil in the engines top half , so reducing wear and tear from cold starts.

BAD!

General Remarks on Chlorinated Additives.

A number of ‘add-on’ additives intended to improve the performance of commercially available automotive lubricants have been marketed in recent years, under such names as ‘Xxtralube ZX-1’, ‘Metol FX-1’, ‘PPL Anti-Friction’ and ‘Activ-8’.All such products share the following characteristics with ‘X-1R Friction Eliminator’:-

1)They all contain chlorinated paraffin ‘exteme pressure’(EP) compounds first used in the 1930s in heavily-loaded industrial gearboxes, and in some automotive transmission applications, mainly hypoid gears.

2)They all corrode copper-based alloys at moderate temperatures, easily exceeded in all engine, and most transmission applications.This problem was recognised in the 1930s, and chlorinated compounds were never used in transmissions with bronze bearings or gears. No responsible manufacturer ever suggested using them in engines where their increasing activity at high temperatures could lead to piston ring corrosion and bore glazing. (For the same reason, modern ‘hypoid’ additives are not used in engines, even though they are much safer than any chlorinated additive.)

3)X-1R Friction Eliminator and its clones are based upon very outdated technology, which was abandoned by responsible lubricant manufacturers for automotive transmission uses in the 1950s. Chlorinated compounds still find applications in metal working, but their use is on the decline because of health and safety considerations.

4)When burnt, chlorinated paraffins produce corrosive hydrochloric acid, and organo-chlorine compounds including the highly poisonous phosgene gas. Apart from these corrosion and health hazards, with petrol engines the deactivation of exhaust catalysts is also a problem.

5)Unfortunately, these additives give spectacular results in simple EP test machines such as the ‘Falex’. As a marketing ploy, a demonstration of this type looks impressive to those not aquainted with the above facts. Also attractive is the low cost of chlorinated compounds, allowing profits of several thousand percent to be made.

Cheers Simon - that's really useful. I once saw an ad for ZX-1.....it seemed too good to be true and thought there had to be a catch. At the time, I couldn't see what the catch was and was vaguely tempted by buying some and whacking it in my old Fezzie. Am very glad I didn't......

Thanks for the explanation.
