Well, this is my personal opinion. I have nothing against lubeguard and Q8. I'm just trying to understand why we need it.
Engine oils like Q8 are specially formulated with specific cleaners and lubricant materials to work best at the indicated engine oil weight and temperature. Adding additives basically alters that structure and basically defeats the purpose of the oil's cleaning and lube abilities.. so why bother with good oil in the first place? Use the cheapass one and add lubeguard la like that.
It doesn't defeat the purpose....there're a few types of engine oil additives available commercially, as according to wikipedia.org
-Zinc dialkyldithiophosphate (ZDDP) additives, which typically also contain calcium, are available to consumers for additional protection under extreme-pressure conditions or in heavy duty performance situations. ZDDP and calcium additives are also added to protect motor oil from oxidative breakdown and to prevent the formation of sludge and varnish deposits.
-In the 1980s and 1990s, additives with suspended PTFE particles were available to consumers to increase motor oil's ability to coat and protect metal surfaces. There is controversy as to the actual effectiveness of these products as they can solidify and clog the oil filters.
-Some molybdenum-containing additives to lubricating oils are claimed to reduce friction, bond to metal, or have anti-wear properties.
-Various other extreme-pressure additives and antiwear additives
