I recently bought a 1982 Saab 900(2.0 litre petrol engine), runs great. I want to keep it this way for as long as possible and am wondering if to use some additive like for example Xado from the Ukraine - has anyone used it and if so what are your impressions. What is the advice on oil aditives in general? Also, any advice on what oil I should use would be greatly apprecdiated, ie. mineral, synthetic based, etc.

I don't recommend oil additives, if the oil manufacturer didn't include it, it doesn't belong. Try a premium synthetic motor oil, the additives are already there. Best of luck, welcome to the board.

Vlado,

Ipquick is right.Lubricant companies use various mechanical methods/equipment to introduce additives in base oils. Apart from elevated temperature blending tanks have mechanical stirrers, baffles etc. All these operations have specific batch times as well. The combination of various additives and its compatibility is tested in advance. All this is carried out by the Chemical Technology groups which also calculates Material and Energy Balances (MEB) of the product.

It is hardly likely that these actions can be replicated by individuals at home or in a smaller scale. Hence the recommendation from "any Lubricant specialist" is, do not mix additives on your own.

Valdo - You asked if anyone has used XADO. Yes I have and really appreciate what it has done to the improvement of Gas Mileage. I have a 2000 Buick Century with over 100,000 miles on it. Most recently on a 1,100 mile trip, I average 28.5 Miles per Gallon. I believe XADO does work as advertised.

Maybe try an AutoRx flush for your engine...

Quoted from BITOG...
...Then a high quality oil. Ex: Castrol Syntec "Made In Germany", a very unique oil in its use of PAO base and esters with cutting edge technology.

I used to use Mobil 1 but now am a convert to Castrol Syntec. As with M1 use, I check my valve covers, they are clean. Quick high-spin starts in -25 C weather, good oil temperature, coolant temperature and my engines are quiet when they idle. What I like about this GC is the oil is towards the high end of the 30 weight scale, so when I run my car or truck hard it handles higher temperatures. Good for seals.

I would try to be more educated about "additives". Few offer return on investment, many deliver what they say they can but at a cost of reliability elsewhere.
Not too much as good as your choice of a quality oil. Pretty well any oil that is SL or the newly SM rating....does not require additives even for older engines. For older higher mileage engines a good conventional oil will do just fine when performing regular oil change intervals.

I would recommend a good 'high mileage' oil like the MaxLife formulations of Valvoline, High Mileage Havoline, etc.

Xado is not an oil additive in the conventional sense. Rather than reacting chemically with your oil, it uses the friction energy normally associated wear to trigger a reaction that restores and coats friction surfaces. Yes, I sell the stuff but I promise you it works like nothing you have ever seen, both in improving economy and operation.

Xado, how 'bout some more info. I simple statement that it works is not of much use. How does it work, what's it made of, how does one use it, how much does it cost, both initial cost and cost per dose, what can I expect, is their any warranty and were is it sold?

Hi Barkerman,
Sorry so slow to respond. I'll watch this forum more closely. Lots of info available at http://www.xado.com or http://www.xadoshop.com You can call my office at 888-399-9090 if you'd like printed matter.
