Nothing comes close to redline 5w30 at killing tick. It's really too bad that it wasn't a different brand name that did this, as somehow mentioning that brand is near a cusword around here. Go to ram forum and find out that time and time again this kills the tick. Go figure that the one formula full of aw/ep additives and pao ester based actually is able to make that metal slide better then sparce api modern formulas. Lubeguard biotech has earned the nick name poor man's redline, as it is the same technology but because it is only a % of that in the sump, it hasn't been as good as killing the ticks, but most certainly worth a shot. Moly additives are the one additive that are NOT snake oil, of course assuming a "certain" formulation. Some so called moly additive contain no moly, such as molygen, some others have near zero moly and are oil thickners such as shaeffers. Warm idle tick is the most insidious of hemi ticks, you cam is being starved proper lubrication. We got guys tuning idles up as well. If you ever try redline 5w30 has had the most success, even over 5w20 and 0w30, and even 10w30. But, if you live in snow country many guys use the 0w30 as some of them have had start up slap on the thick 5w30. 5w20 redline killed my hemi tick since I first used it. I have only heard hemi tick three times since then, once was due to a filter, once was due to trying 10w30 redline that my truck didnt like, and one was when the truck sat for a month or two due to the CA fires. Most people that have success with redline and ticks it takes a while like up to 500 miles for the tick to disappear. If you are concerned you can go to ram forum and post a question, likely 10 different forum members will share the same experience with you. It is not 100%, more like 80%, but considering all we are talking about is an oil change, it is a pretty amazing result.
