Redline 10w-40 on 2004 Dodge SRT-4 Comparison....

[Idrinkmotoroil]

Just got my second analysis back on this vehicle, engine is turbocharged 2.4 L, driven relatively hard, mixed driving. I also did one road course event on this sample. The previous sample is with a Mobil1/Redline 10w-30 brew, it had one quarter mile day visit on it, so I think the two samples should be similar in terms of engine use. Previous sample used 1 quart Redline with 4 quarts Mobil1 10w-30 visc, posted previously. This sample was 5 quarts Redline 10w-40. Mileage was similar. This sample seen a drop in iron wear but increased aluminum and a bit more copper. Lead is still zero, which I find strange, wonder if there is any lead used in the Chrysler bearings, two samples with zero lead on a turbocharged engine is wild.

First numbers are the Mobil1/Redline 10w-30 Brew
Second numbers are the Redline 10w-40 OCI.
5500 kms on first sample, 5200 kms on second.
Engine has approx. 13,000 kms at time of sample.


Here we go:

Iron - 5 , 3
Chrome- 0 , 0
Moly - 114 , 429
Aluminum-2 , 5
Copper - 1 , 2
Lead - 0 , 0
Tin - 0 , 0
Boron - not tested
Silicon - 12 , 7
Sodium - 9 , 20
Zinc - 784 , 896
Potassium - 1 , 3
Nickel - 0 , 0
Silver - 0 , 0
Soot - 0 , 0
Sulfation - 182 , not tested
Oxidation - 387 , not tested
Nitration 62 , not tested
viscosity, not tested, 12.9 cst

No antifreeze, no fuel dilution, no water in either sample.

Next sample to go in is a Mobil1/Redline 10w-30 brew with 2 quarts Redline and 3 quarts Mobil1. Right now I am running a full 5 quarts of Mobil1 10w-30. So I should have a good idea of how things are working once I get all the samples together.

This lab is having a hard time analyzing oxidation, nitration as the Redline mix is throwing off their infrareds. They said I should send in virgin samples of the oils being used as they need the information to do a full analysis. I got viscosity readings this time around but not the first sample. Still good information overall. Lab costs are relatively inexpensive so I dont mind.

any questions let me know , thanks.

I think you are right on the money with the Redline/Mobil mix. I have one quart of Redline mixed with Schaeffer's on my son's Acura. And I intend to do the same with my vehicle which has 2 quarts 5W-20 and 2 quarts 10W-30 Redline.

I think allowing for break-in for the first run that the brew of yours outperformed the pure RedLine. Good show

I think the two samples are relatively close in terms of wear metals, if anything I would call it a tie given the small differences. Perhaps if you consider the viscosity difference the Mobil1/Redline brew might be working better. The Mobil1/Redline brew is certainly more cost effective for me, and given the short OCI's I have to run with this engine its a better deal. I'm not concerned with TBN numbers as my OCI's will not be much over 3000 miles.

Hmmm...I would of thought the Zinc would of been in the 1200 range for this OCI?

 

[Idrinkmotoroil]

yeah zinc appears low in both samples, I thought it would have been higher. Moly also seems to have been taken up as all my other Redline samples were over 500 ppms.

Why are you doing 3k miles intervals when oil is clearly showing you could go 5k miles easy

mainly for warranty purposes, this engine calls for 3000 mile changes. I'd love to use straight Redline but its too expensive to dump at 3000 miles, I dont feel so bad doing it with Mobil1/Redline mix as its more affordable and it appears the wear is very low too.

Redline isn't API certified is it? I don't question that Redline is an excellent oil, but if your vehicles says to use API rated oil and Redline isn't API certified, you are technically not in compliance with the warranty requirements. Be sure you have enough M1 receipts to cover your oil use.

Your risk of a problem is small, you risk of them finding out you are using a non certified oil is also very small, but real. It's even smaller if you don't admit to it and have M1 receipts

that's one other benefit of using this brew, I have Mobil1 receipts, but get to pump up the additives with non-API oil. best of both worlds, at least until I can get a full run of Mobil1 tested in the next while, we shall see.

I run a non-API'd oil in my warrantied 03 Mustang GT. No problems with warranty here...of course I'm using straight Red Line, though.

I would try a different lab.

I dont mind this lab (SOS Fluid Analysis - CAT dealer system). For my purposes they seem to work fine as I'm most concerned with viewing the wear metals data. They are relatively inexpensive and it's easy to use as they courier the oil to the lab for me from their dealer locations once a day. They offer more detailed reports for added costs but I really dont need all the other info as I'm committed to 3000 mile changes for the most part.
