(T) do you use oil additives

Just wondered' as halfords has a shelf full being brought by weekend mechanics
You might want to read this first http://www.fordscorpio.co.uk/snakeoil.htm

this is very interesting ...any good machenic will tell you exactly this, in not so many words... i,m an oldy & anyone on here who knows
.. anything, spend the money on good engine oil..one of the best things you can do to your car is change oil&filter more often a lot cheaper in long run

Just hope it will save some of the young uns some cash
p.s i am a mechanic @ have been for 29 years i worked on renault 5's with column change, my first car was a renault 17 TL

i used to do all my own servicing & most of mechanicle stuff myself but i,m an old git now so i cant get under the car any more doing anything to the car now is a major hassle to me due to aches & pains eyesight not what it used to be etc etc .jings no much wonder i,m a moaning old git getting back to the additives though, i do hope the young team on here will take note, and repeating myself again using good oil & g change more often
happy motoring everyone

Total waste of money. A 'good' fuel system cleaner every 6months is worth it such as forte.


That reminds me mine needs doing

Very enlightening. Thank you.

i agree much soo

the only thing ill ever put in my oil filler cap is oil!

The sense of putting PTFE into a setting where it's likely to see the temperatures it sees in the combustion chamber never made any sense to me. A place I was working at had a major incident when a filter housing caught fire. It was an active charcoal filter, and that in itself isn't a problem. The problem was that there were small amounts of PTFE in the mixture.

Now, look at DuPonts MSDS for Teflon (PTFE) and look at the possible decomposition products and you will see hydrogen flouride. Hydrogen flouride, also known as hydouric acid!!!

Now, have a look at an MSDS for hydouric acid and see what a nasty little beast THAT can be. Here's a hint, it's used for glass etching as it's the only acid that will dissolve solid glass!

From a HF MSDS, (note the capitalization is on the MSDS, not mine!)

POISON! DANGER! CORROSIVE. EXTREMELY HAZARDOUS LIQUID AND VAPOR. CAUSES SEVERE BURNS WHICH MAY NOT BE IMMEDIATELY PAINFUL OR VISIBLE. MAY BE FATAL IF SWALLOWED OR INHALED. LIQUID AND VAPOR CAN BURN SKIN, EYES AND RESPIRATORY TRACT. CAUSES BONE DAMAGE. REACTION WITH CERTAIN METALS GENERATES FLAMMABLE AND POTENTIALLY EXPLOSIVE HYDROGEN GAS.

So, tell me again how it's a good idea to put anything containing PTFE into an engine?

did anyone know that it was ici that discovered how to attach ptfe to metals to form non stick frictionless coatings

they decided there was no use for attaching ptfe to metals and sold the idea to DuPont who later dubbed it Teflon and made millions selling cock ware lol

and i can tell you that under no circumstances will ptfe attach itself to your engine under normal engine operating conditions

i would say the friction loss and engine power gain in those tests on the article were probably due to engine wear we all know what new engines are like for the first 1000 miles take a wile to loosen up and a fiat fire with 100k on i can tell you is very nice and free
