Is your diesel a powerstroke or cummins or duramax? 15-40 is recommended for my truck. My injectors completely rely on High pressure oil to function properly. The Schaeffers oil is pretty darn good for start-ups and extended OCI’s. As far as Lucas products.......eh...I was told to stay away from that stuff.......many testimonials about Lucas entrapping air in the oil on another forum I go on. Just trying to find out if anybody uses MMO along with the Schaeffers.
I did not know both of your vehicles were diesels, and was extrapolating concepts of new technology valve designs on gas engines; even though, I know about the high compression requirements of diesels. And about the specific Lucas oil additive, carb/FI/gas additive, and power steering fluids too, no one told me anything: I experienced them successfully myself. I am real cautious about anything I hear on the web, especially if it is in chimed in groups. The only way to know anything is to try it, assuming it is a safe alternative. There are so many shades of gray, there is ‘no’ absolute truth.
here’s the report. Its a 7.3 Liter powerstroke engine.There’s 189k on the engine.Take into consideration this has been thru 3 truck pull’s along with 3100 miles, and this engine has injectors in that flow 250 percent more fuel than stock. Passed with flying colors.You will see greater numbers in the Molybdenum and Magnesium.....those are additives in Schaeffers oil.
Just think, if only had a deck gun on it you could invade a country. May I ask why you chose Schaeffer’s (a fine choice by the way, there’s no arguing about that) as opposed to another kind of oil more inline with a tank like the F-350 (say Rotella T-5 or T-6)? I ask because I am considering switching a much lighter truck (the original Ford Explorer) over to Rotella T-3 or T-5.

I did a TON of reading on Schaeffers before switching. I did use Rotella before and there’s nothing bad about it, I just felt with schaeffers was more inline with what I wanted for my engine. The molybdenum that is in schaeffers is mechanically plated to your internals....I liked that, and my blowby has decreased, telling me that the minuscule scours and voids in my cylinder walls have been eliminated somewhat, increasing compression and power. They list the main properties in their MSDS’s, amsoil doesn’t even do that. I think if you read up on them you’ll see why I chose to go with schaeffers. The oil is also very affordable. Just curious, did you have an oil sample analyzed yet? I think every engine can be tempermental to what type of oil you use, a UOA can go a long way for chosing the right oil for your engine, or atleast narrow it down. I have used Rotella 5w-40 and 15w-40 in my truck(with no issues), with the modifications on the truck. I just wanted something with alittle more umph. Schaeffers has proven that to me with every truck pull I competed in this year. 0 breakdowns, 0 engine issues. Hope this helps alittle.
UOA looks good Superduty! Some slight thickening, but excellent for the abuse it was put through and the mods it has.
Are you going to use MMO yet?
I used 16 oz on the last 200 miles before I took a sample. I don’t think it was enough to make a impact on the UOA. I just changed the oil 2 days ago, I’m probably going to run this oil for 4k( pulling season is over) with just oil, get another analysis done and go from there. I’ve always had good UOA’s with MMO, I just want to see what the results are with this type of oil. I regularly use MMO in my wife’s vehicle and will continue to do that. Updates to follow.
Discovered some shaft play with my turbo. This turbo is less than a year old and has less than 6k miles on it. I thought I’d take it off and send it to the dealer for warranty repair. He takes it apart and finds no signs of misuse or abuse. He sends it to the Manufacturer for warranty. The Manufacturer takes it apart and says they found signs of misuse and abuse. Now the dealer contacts me and says they want $625 to fix the turbo. I say, either it’s covered under the warranty or I’m coming to his shop to collect the full price of the turbo.
I inform him that I regularly have my oil analyzed and there is absolutely no indication that the thrust bearing (made of brass) was even wearing at all. Copper and zinc make brass, as you can see on my oil analysis, there’s only 3ppm of copper and zinc is within normal parameters. Only after I sent him my oil analysis he then conceded and told me that the turbo would be repaired immediately and sent back at no cost to me. Obviously someone was trying to be shady.
I’ll be taking another oil sample this week. I guess the point is.......watch it guys.
PS: I figured the play was a thrust washer, since iron levels were elevated alittle, not the bearing(brass part). Only thing that made sense was the dealer swapped out parts on my turbo to make it look really bad so the Manufacturer would warranty it with no questions asked.
Thanks for posting this. What did they say in the comments?
Depending on who you go through for oil analysis, they may not have any comments. afaik, only Blackstone will give comments.
I’m no chemist, but looking at the UOA, is this a good or bad run? Some stuff seems wayyyyyy high compared to the universal averages (Iron, Moly, Magnesium), then some items are wayyyyy low (Boron, Calcium)
Something I have learned from reading users UOAs at BITOG, that TBN is lookin good......you certainly could have ran that oil a lot longer
No water, no antifreeze looks good......next sample, may consider giving the vehicle a good 20-30 minute highway run before taking the sample......may help to burn off some of that fuel.
BTW, what’s with the flashpoint? Yours was 395oF, but the universal avg is 415......seems kind of low. Would that be considered good or bad? I’d think it being lower would be good, won’t have to worry about oil “burning” (flashing), or am I misunderstanding that concept?
Flashpoint is probably depressed from the large amount of fuel in his oil.
The things that are way high are inherent in his oil- the whole reason you buy Schaeffer’s is because you like the high levels of moly in your oil.
Iron is a bit high, as is magnesium, but unless I am mistaken he just recently had a new turbocharger installed and what we could be seeing is the break-in period for that.
A lot of the other elements listed are actually residuals from engine casting (though probably not now) and doping in the metal.
Yep, I just had the turbo replaced. I sent my oil to blackstone. Their comments go as follows.
“ Brass shows up in our reports as copper and zinc. Copper read low, so we don’t think you have any problems to worry about there. We can’t comment on zinc because zinc is used as an anti-wear additive in most oils, and that masks zinc from brass wear. In any case, all wear looks good, so we don’t see any signs of a problem here, though oil analysis doesn’t find every problem. Let us know what you find out about the turbo thrust bearing. Fuel at 2.0% is a borderline concern - maybe idling/cold sampling explains it. TBN= 6.7, still good. Go 2k more miles on this oil.”
Funny thing is, the day I pulled the sample, I was running some errands and every time I stopped somewhere I never shut the truck off. I’d put it in “whisper mode”, pull the keys and lock the doors to go into the buildings I had to to finish my errands. The truck was sitting about 2hrs before I pulled the sample. It was not hot. Schaeffers uses Moybdenum and Magnesium as anti-wear additives along with the other common ones, that’s why those numbers are high. The Iron may be characteristic with the oil, as long as it stays where it is and establishes a “trend”, I probably won’t worry about it too much.
