Greg thanks for updating us, we want everyone who has tried it to vote, so please vote unless you are waiting to see the tick subsides. I encourage you to look at bolts again, but if your hemi is still warm idle ticking please vote as well, gives the forum accurate info.
side note every uoa of redline is heavy the first time, it could be to leaching ions or increased wear from anti wear additives. Anti wear additives create more wear at first, then lower, it is a fact, that is why we have zinc break in oils.
I am reading through this thread and have seen this mentioned a few times. What is meant by "uoa of redline"?
Sorry if this has been mentioned. I am just trying to figure out if this is the best course of action for me.
Read this thread, uoa = used oil analysis. It will tell you how bad the wear us, many guys like me with hemi tick have pretty crappy wear numbers. Multiple ones show you if your strategy is working or not. If you want one this place is great. If you do get one, let me know I'll walk you through a couple things.
If you are changing oils, I would wait til you found an oil you were going to use long term, so you can set your oci, oil change interval. If you send the uoa off anyhow, make sure you take sample a little warm and fill the container full. Usually you need tbn, but like I'm saying that is pretty much useless until you use a single oil long term. Two main reason for uoa's, set oci and see wear, and some other smaller things that they will let you know about.
sorry, remind me, it is a new truck? how many miles? what oil did you just run?
So yeah 56k miles would be a great time to do a uoa. The second and third uoa's of redline seam to be the best at revealing your wear patterns if you will do one with redline. Universally it seams the first redline run shows heavy numbers, there are some theories to why, leaching ion's or the fact redline has so many ep/aw that is knocks down some metal other oils don't, but if you see the uoa thread this trend doesn't continue, 2 and 3rd uoa's clean up nicely. At 7500 miles if you are staying with that as an interval, you may just opt for tbn once to verify, but generally speaking that is a pretty safe interval with freeway mileage.
Sorry for all the questions, but what does the text in red mean?
No worries brother, ask whatever questions you like, if fact I like when people do.
So TBN is total base number of a liquid, TAN is total acid number of a liquid, in our case oil. As you use oil, the TBN goes down, and the TAN goes up. So you decide what level is a good level to change your oil at, I prefer 3tbn, the labs say it is ok to go down to one tbn, I disagree. When you run out of tbn, acid eats your metal. TBN level is the best thing to use to set an interval, so at 7500 miles you send in your sample, and pay ten bucks for tbn, and blackstone will give you tbn level and they will suggest an interval for ya. cool?
Ok, most guys would say more uoa's the better, but I am budget oriented and I like to get value from my money. So saying all that, I'd skip this one since you committed to changing oils, brand doesn't matter, you are simply using a new oil. And we know the first run of redline would not be an accurate level to how your engine will be wearing. heres the thing, if redline didn't kill your tick because it's mani bolts are you still gonna run it? if so, I would do my first uoa on the second redline run. But, if you still have tick and decide on another brand, then once you settle on whatever brand you will settle with, do a uoa as soon as possible, perfect timing for a uoa with your truck. Only wait til second run if it's redline. Just my 2 pennies.
Yes, tbn is an add on.
