I was perusing the gas engine uoa forum and a couple of them mention using some kind of oil and or gasoline additive.Can a "real" determination of a particular oil verse another be made when using additives???? If type A oil was used for the first uoa with no additives and less than stellar results is compared to type B with additives used, can anyone honestly say that type B is better for their engine??? If LC or any other oil booster type stuff is used how can a fair determination be made using a uoa on the actual oil itself???? To honestly see how any oil is for your engine should'nt it be used at each oci and maybe tweaked by using LC,FP,different filter, then compared to the previous uoa and so on???? If you flip-flop between brands and the use of or no use of additives no trending can really take place,can it???
