Click on Uno-Lung's name, down at the bottom of his specs is his "check Uno-Lung's last 25 posts" -- when you review his entire post history end to end it is obvious that Uno-Lung only exists as somebody's sock puppet, so you understand a position of editing or deleting his comments upon sight as troll food, which I will promptly go and do.
Is there any merit to the excess detergency thing? Yes, there is history of people saying don't use full diesel oils in old V8's as the old pleated rubber main seals depended on a sludge build up to work correctly.
Removing all the sludge did cause oil consumption in these older V8 style engines.
Performance issues are a mixed bag. Muscle cars running actual races don't use any detergents at all, as their oil gets changed at races end and ANY performance loss is anathma to a racer. All race oils sold as race oils lack long distance detergent packages as racers don't need them and don't want them.
Top fuel dragsters making 2,000 hp out of a blow fueler actually have some decent discussions on the evils of detergent oil on their forums (to them a 1-2% potential loss in hp means not winning after all).
Filter Uno's real points through a few reality check filters though, first in Rotella we are using a HDEO instead of a full diesel oil and Rotella is formulated and approved for use in gasoline engines (and is tested and approved for motorcycle engines).
Next, the whole world uses this stuff all the time, and if any detremential effects were out there they would have page after page written on them on bike sites and on auto diesel sites and on BITOG.
So, let me go take care of my favorite sock puppet's excesses and all you nice folks have a good Saturday afternoon calmly and rationally discussing your favorite subject.
..... now if Uno is a sock puppet, whose hand is stuck up inside his arse ?
