Here are the results of my oil analysis from Terry Dyson, with 2394 miles on 10w30 Maxlife.
My car had 68,318 miles on it at the time of the sample, and I was running an AC Delco PF25
oil filter. This oil was in there from May 10-June 23rd, and most of the driving was my daily
commute to work (48mi round trip) It's mostly highway driving, however in rush hour, so one
minute I'm doing 85mph, the next I'm stopped. There were also 14 quarter mile runs on this
interval, plus a lot of full throttle blasts too. The previous oil before this was Mobil 1
Tri-Synthetic 10w30 (so a tiny bit of this oil would be mixed in with this bunch)
This is also the older SJ formula of Maxlife, and I added 1/3rd of a quart of oil during this interval.
Copper-4
Iron-15
Chrome-1
Lead-19
Aluminum-6
Silicon-7
Tin-3
Moly-1
Sodium-8
Magnesium-328
Zinc-1220
Potassium-0
Phosphorus-981
Calcium-2660
Water,fuel, glycol-all negative (the scale =neg, trace,positive)
Soot-0
Oxidation-80 on a scale of 199 (40%)
Nitration-57 on a scale of 199 (29%)
Sulfur-54
TBN-8
Vis at 100c-11.4
So the thing that disturbs me is that low moly number? Could it all have plated up? Or does
Maxlife not have as much moly as they claim? Or perhaps they only have moly on the new SL
formula? Or only in the 10w40? My next analysis will show for sure, and if I don't see higher
moly numbers I'm gonna be
I'm currently finishing up my Auto-rx treatment, and will put in the SL Maxlife 10w30 on Friday.
I will probably run that out to about 5k and analyze it again. That should probably be
sometime around October. (I hope someone else has analysis done on SL Maxlife 10w30
before then so I know if it has enough moly in it!)
The TBN number is encouraging, especially since the SL rated Maxlife supposedly has triple
the detergency, so I should see if that's true or not on the next analysis.
