In the seventies honda made some V4 motorbikes which were blowing up all over the place once out of warranty, turns out hondas own oil fitted at dealer services contained moly. I used to put molyslip into honda ohc engines to overcome the 15 second delay in getting oil to the cam on a cold start, I also used gearbox molyslip in BMW boxer gearboxes which definitely improved the gearchange.

I've yet to see any convincing evidence that slick 50 does any long term good in an engine - Particularly a diesel where oil changes need to be regular and frequent. However, in a gearbox where oil hangs around for some considerable time and is relatively unpolluted by sulphur compounds, I'm sure it can make a difference.

Oils are good these days, so as long as you use a decent oil there is very little benefit to be had from adding an additive. The only time an additive will do any good is when your oil is lacking in some respect, usually because the engine it knackered.

Sorry to bring this topic up again but after reading though this topic i have to agree with some of the member that i also dont like useing addative in the engine but when it comes to the gearbox iam at a loss meaning i changed my gearbox oil in my 93 k reg aura TD about 6000 miles ago and at first things were smooth but it dosent fell as nice as it was so i was thinking about putting in this slick 50 this weekend to help things. Would it really help the oil in the gearbox ? and help keep the gearbox healthy? if yes then come satuday iam off to buy some.

As has already been said, I wouldn't use an oil additive in the engine unless it was very worn. I've used Slick50 in gearboxes before with good results - my ancient AX still has a lovely smooth gearbox at 180-odd K miles. I was surprised how expensive it was when I brought some for the Xantia, and I'm wondering if I'll try another product next time. Unfortunately, I brought the wrong oil for the Xantia gearbox and with the Slick50 it is ok but not good. I think I'll always use an additive in my gearboxes since the difference it made to the AX.

Having seen the result of using Slick 50 in a friends MGB GT I wouldn't go near it with a barge pole. The treatment itself didn't seem to do anything, but when he changed to a semi-synth oil at the next change, the new filter got blocked within a day - on inspection we found great flakes of some deposit (teflon?) floating around in the oil. Luckily he managed to stop and drain the oil (and flush the engine) before any damage was done.

There are dozens of websites about oil-oil additives, etc etc.. Google finds them in seconds..
Personaly I have used molyslip in every car engine I have ever owned and never had a major mechanical engine breakdown, whether the molyslip had any effect on that I really don't know.. I just like to know its in there.. [^]
When I was young it was common to use sawdust in back axles, nylons in gearboxes, and raw eggs in radiators to cure water leaks.. [:I] [:o)] We are spoilt for choice now. [:)] lol..

Well I tried flour in the diff, eggs in the rad, lard in the brake fluid and sugar in the power steering. It didn't cure any of my motoring problems, but a great cake popped out of the exhaust!!![:D][:D]
Sorry, As you were.

I have tried various additives and "wonder potions" over the years.
The only ones that worked were Morey's (Lucas oil stabilizer) in an older engine to reduce oil burning and a product called Pro-Ma MBL (metal based lubricant) that quietened hyraulic lifters very effectively.
If your engine is sound the extra money you would spend on additives is better spent on better oil or more frequent oil changes in my opinion. Oils contain so many additives these days anyway - adding more may upset the chemical balance of the oil or so the oil companies say.

I think I've given my views on these snake oil treatments before; won't cop them in engines but always use in transmissions as I've found some pretty outstanding results in them.
I've watched this one from a distance since it was re-born but Scott just used the magic words; Pro-Ma....[:(]
Back in the days when I had my business, I didn't have the time or inclination to do my own servicing so I paid a goose to do it for me; this one had a reputation but unfortunately for me, it wasn't until it was too late that I discovered that teh people who recommended him didn't use him (ask why?)
Had the car in for a service and am told he's put this special stuff in the engine; soon after I notice the engine begins to burn oil. Car a CX had done a few miles so I put it down to wear & tear. I buy another CX, later model and after a couple of years, I take it to same goose for service......"I've treated it with angels p!$$" he tells me when I collect.....a few weeks later I find it also is burning oil but to compound the felony, he has sent me home with a bottle of this wonder engine elixer to use in my almost new mini tractor I use on the property. About the same time as the second CX clags out, the new tractor also decided to lose all its compression and goes in for a warranty repair. The engine is sent to head office and I get a call; "You've been using an additive haven't you?" to which I tried to duck the issue expecting the worst, and it came; "It's ripped the guts right out of the insides of the engine; what did you use....Pro-Ma???" when I asked why he said that it seems that I wasn't the omly one and they have a policy of rejecting warranties on engines with additives in them. I eventually told him that the guy who sold it reckoned it was suitable for that application and he just laughed and said it wasn't suitable for ANY application.
I had done an oil change on the engine before it went away & they could still pick it, in fact they reckoned they could tell each engine with an additive in by a combination of damage done and residue left, so, it'd be a braver man than I who would use it in a modern faily hi-tech engine.

Hi Alan. VERY interesting about Pro - Ma. I assume this was the MBL8 product. A friend of mine used to sell it and it did really work to sort out noisy hydraulic lifters. I used it once in an older car with success. But I would never put anything but what the manufacturer recommended in any newer high tech (eg. VVT or VTEC) engine. Just not worth the risk.

Yeah Scott,
I eventually got to the bottom of what it was all about.
It was being manufactured down the gold Coast at either West Burleigh or Ashmore/Molendiner area and was sold by using a pyramid/MLM type of system.
Being a "specialised" mechanic/repairer he just simply put it into cars and added it to the bill and after the event would then produce all this propaganda about it before he presented them with the invoice with it already charged out. I discovered he had gone a long way up the chain and was a bit cunning in that he didn't try to sell everybody on the idea of selling it for him, (a la Amway style) rather he retailed it and got his profits plus overriders which made each sale worth while and then sold the idea to retail it to other professionals so he kept both his number of downlines growing as well as group turnover and was guaranteed of direct sales every time someone brought a car in for a service.
He never admitted that was what he did but I met one of his downliners by accident and he gave me the story and a few other horror tales to go with it.

Additives for engines are a total waste of time. How many times do you need telling?
