Poll: Oil Pressure Build-Up Time And Oil/Oil Filter Usage??? - Diesel Forum

AllOutFirefighter13 · 03-10-2006, 10:50 AM

Maybe this poll will clear up a lot of questions from those (including me) who have questions regarding what oil and what oil filter they might want to use. Also, I'm particularly interested in the amount of time that it takes for the oil pressure to build up. To measure, please count the number of seconds it takes for the oil pressure needle to go from no pressure to full pressure AFTER the engine has fired up (this does not include cranking time, just after you hear it first fire up to when you see the needle move). This was my original question, but I'd also like to know what percentages of people are using 'X' type of oil and 'Y' type of filter. Thanks in advance for taking the time to vote!!!!

Also, on Question 1, please pick a weight of oil and indicate whether it is dino or synthetic and on Question 3, if you choose other, please include the brand.

Mine's kind of split.

Last 2 changes have been 15w-40 Rotella T but was Amsoil 15w-40 prior to that. After my recent UOA (results back yesterday) my suspisions were validated in that my cold idle, short trips were letting the fuel hang around in the oil and not cook out. I'm also still seeing higher iron, yet all other metals are well within check. I'm running Rotella for cost reasons as I'm starting to change more often, and UOA hasn't shown me any advantage in using synthetic. Cold start and drivability is the same as well; good.

Filter is still the same, Motorcraft/Wix/etc. All the same thing.

How do we access the information you gather using this poll? I have responded to other polls but I don't think I've ever seen the end results.

I'm not sure if I fully understand your question. If you are talking about seeing where everyone is voting at, all you have to do is vote yourself. If you are talking about information to the end result of the poll, I'm not sure that there will be an end. I created this poll to answer a few of my questions, but also to have that knowledge available to the rest of the 6.0L PSD community. There might be something I'm missing???

The results are useless as they are displayed. I can see that a high percent use motorcraft filters, and a high percent use 15-40 and a high percent see oil pressure in first 1-2 seconds. What I can't see is if the high percent that see quick oil pressure are the same ones using motor craft filters and 15-40 dino. There is no correlation feature in the poll and therefore, the results are useless as they are displayed.

For all intents and purposes, the results of the pole are useful to me. I did not intend to get each user's situation...had I wanted that, I would've asked for individual replies. If someone wants the information you mentioned, then by all means, create a way to do that.

stuckinthemud · 03-14-2006, 04:52 PM

Maybe you could share with us what you're trying to determine from the poll then. Maybe I'm reading too much into it and trying to tie data topgether that doesn't need to be tied. I'd be interested in results, but I just don't get what you're looking for.

Not sure what napa uses for filters, But the last napa filter i got was different from the normal donaldson ones i always use. it takes 3-4-5 seconds to build oil pressure now. Napa filter is comming out today. Every 6.0 i have,(4 of them) Have got pressure withing 1-2 seconds tops.

My original question was about the time it took for these engines to build up oil pressure after starting up from sitting overnight. After reading all the posts about who was running what weight oil and if it was synthetic or not, I decided to incorporate all that into a poll. Like you said, all it does it let us know the majority of people that are running synthetic vs. dino, and also what weight oil it is. I figured that for those that kept asking about what kind of oil they should run, they could take a look at what the majority of people are using. Maybe this would eliminate some of the redundant posts, maybe not. Like I said earlier, it would be nice to have everyone give specifics, but without them posting individually, we won't know that information. This poll is just like any other post on this site...you can use the information if you want, and if not, then read some of the others that interest you.

this poll will lend to incorrect assumptions. the oil pressure sender on this beast is an on-off switch energised when the key is in the run position. the injectors run from oil pressure originating from the high pressure pump. No pressure-no start. You cannot quantify oil pressure rise time from one on-off switch.

What about adding a question that asks if they have gauges? That may make it more useful.

Alloutfirefighter...I am interested in this information. Otherwise I would not have posted. I think you and I are looking for the same data. But I am a statistics junky and to draw a conculsion, I need to see correlations. Sorry if I'm getting too picky.

Wolf,

This poll could lead to incorrect assumptions, but only if one were to assume without proper knowledge. I am a firm believer that if I want to own and work on one of these trucks, then I'm going to take the time to learn the systems. Yes, this oil pressure gauge is actuated by an on/off switch (I personally don't like it, but getting an analog version wasn't an option when I ordered. I humbly disagree that I cannot quantify oil pressure rise time. What I originally asked for was when the gauge first registered pressure (movement of needle) after the engine started, not when the system reached a certain pressure (as these "switches" register good oil pressure at roughly 6-8 PSI). Also, as far as the injectors running off of oil pressure from the HPOP, that is very true. But, "no pressure-no start" is not an entirely truthful statement. The HPOP has its own little "oil pan" to provide oil to the pump. This pan will hold almost 1 quart of oil. I do not have rates as to the GPM flow of the pump, but if there is oil in this little "oil pan", she'll fire up. She won't run for very long, but still fire. Evidentaly the LPOP will keep up (volume wise) with the HPOP as far as flow goes, or we would have problems to where the truck would act like it is running out of fuel, when it's really running out of oil to fire the injectors. See post below for further explanation.

Nate,

I understand the pickiness, as I like to have as many facts on the table as possible. As I explained earlier, all that I wanted to know was when that little oil pressure needle moved after the engine fired up. I included the other information as to the weight and type of oil and which filter was being used for those who kept posting about what kind of oil to use (they could see the percentages and maybe come to a conclusion...maybe not). I didn't need to know specifics, more like popular percentages. Maybe we need to start a thread asking whoever wants to participate to list the things that we have mentioned, or find a way to dynamically include this information in a poll. Perhaps the moderators could start another thread about oils (as they do in the Biodiesel section of this forum). I'd really like to see this, as I too have many oil-related questions and am skeptical about switching. I hope this helps.

Later,

That does help, AOFF. What you're asking is two different non related questions. I assumed you were tieing the two together.

I would like to know if a certian weight, or dino vs synthetic, results in quicker acceptable oil pressure. I'm th8inking that may lead to quicker resposne after start-up. We've seen a lot of posts from people who comnplain that the truck has no get up and go until it's been running a while. I've pulled my truck into trafic before and almost been hit. Many say this is normal...just let the truck warm up a little longer...then someone will say don't let it warm up too long cuz you soot up your EGR system. Well...maybe the answer is oil viscosity...maybe it isn't. And that is where I thought you were going with this poll.

Still interstiong stuff coming up here.
