Torco 5w-30 SR-5, 02,Jeep 4.0, 4000 miles.

[Chris142]

My ave 1st line, univ average 2nd.

27,400 miles on Jeep.
4k on oil
alu 4 - 5
chromium 1 - 2
iron 16 - 24
copper 7 - 2
lead 4 - 4
tin 1 - 0
moly 952(holy cow!) 80
nickle 1 - 1
mang 2 - 1
silver 0 - 0
tit 0 - 0
potassium 2 - 2
boron 16 - 104

silicon 20 - 12
sodium 15 - 6
calc 1629 - 2150
magnesium 10 -26
phos 1057 - 710
zinc 923- 975
barium 28 - 0

vis @210=63.4
flash=375
fuel=.05

tbn= .9

Kinda glad that I drained it at 4k instead of going 6k. The Torco did lower my iron count a little (24 with hav10-30 vs 16).

I knew that this oil would have lots of Moly and I wanted to see if Moly was the magic thing to lower the Jeep iron monster iron level down.

Looks like it lowered it just a tad.......Not $75 worth though. Replaced with Delo 15w40.

I'm a little disapointed in this oil for street use. It's definatly a race oil only?

I dunno whats up with the Silicon #'s. I have not touched the airfilter in quite a while.

Pretty good report, especially for a 5W30. It is almost identical to what I get with D1. I would like to find a reasonably priced and available xW30 that gives numbers as good as this. I would be very interested to see a UOA for the 4.0L from GC or Redline.

Thanks for posting. I have always been curious about this oil. I too am surprised that the TBN gave out after only 4,000 miles.

Chris142,
How many months was the interval?Your silicon is ~60% higher than your other Jeep UOA Topic: 02' Jeep 4.0 Havoline 10w/30, 3400 miles .If it was silicon leaching from gaskets,it would trend down.
Is this oil what followed the Quaker State 10w-40 that was used after the Havoline run?I'da like to have seen a back-to-back Torco run to minimize contamination from the previous oils "cooties".
Except for the TBN,not a bad looking UOA.Is this a Blackstone analysis?

My guess is that most of the higher Si is from Si which is found in virgin Torco oil.

Look at the total amount of moly difference Here

There was a recent thread about this oil and a member assured me Torco said this was a easy 7500 mile oil . I had my doubts in that thread but did not want to argue .

I think this analysis speaks my opinion for me but later on possibly another one will run through here to change my mind

Depending on the quality of the base oil , additives and actual type moly used 50-60 ppm is enough .

Thanks for sharing your analysis .

The oil was in for about 4 months. Yes I drained the QS 10w-40 early and did not sample that oil. I was really exited about putting $75 worth of oil in the Jeep

Yes this is a Blackstone analysis.

Sheesh - TBN was low.

You think the SR-1 ("Street" oil, as opposed to the SR-5 "Racing" oil) has better TBN retention?

I'll have a UOA of the SR-1 posted in a month or so, from the wife's Xterra.

Man o Man I feel tupid , tupid tupid

Thats the SR5 race oil and I take back my post and since I was such a bad bad
tupid man will not even post a retake on it

But here's an S to put in front of a few words that need it
