Full-syn Maxlife "different" than M-1 HM

[FastSUV]

I noticed tonight at Walmart that the Mobil 1 High Mileage 10w30 is a good-old non-energy conserving oil; as it should be with all the extra goods in its additive pkg just like all other High Mileage oils I have seen.

BUT the Maxlife full-syn 10w30 was marked "energy-conserving" to my dismay because it made me think maybe it did not have as much "goods" in it like all other High Mileage oils do.

I did not check to see if the blend Maxlife was the same or not but I doubt it is with all the phosphorus, etc. in the standard blend Maxlife.

That is interesting the 5W30 Synthetic Max Life I have is not energy conserving. I bought it about a year ago.

I, for one, am sorry that a symbol on the front of an oil container causes you to be dismayed.I hope you can find the courage inside to get over it.

I change oil for someone that is not able to do so for himself. He uses Valvoline MaxLife Full Synthetic. I went out to the storage and got a quart to double check. It is December 2008, and it is not energy conserving. It is API SM, SL/CF, ACEA A3, and protection requirements of ILSAC GF-4. I do know that there were some 5 quart jugs of Max Life full synthetic that were mis- labeled saying ACEA A1 rather than ACEA A3, and Valvoline admits this, but they were not labeled energy conserving.

Valvoline does not use high Phosphorus or high ZINC in Max Life or Max Life blend. They use 300ppm moly in the blend and 280 ppm in the full synthetic. They just reformulated in January and also lowered the SA and upped the NOACK of their oils.

Mobil 1 does have higher phosphorus and zinc but much lower moly.

If I remember correctly, Max Life synthetic has a HTHS of 3.56 and Mobil 1 10w30 HM has a HTHS of 3.66. Both to heavy for energy conserving specks of ILSAC GF-4.

Gessh, you can't go wrong with either of those oils.

I agree. According to the data sheet, it is not GF-4 energy conserving. It meets emissions system standards for GF-4, but not energy conserving standards.

Wow, they did reformulate it! Droped the calcium by 500 ppm, added 20 ppm moly, and added a whopping 490 ppm sodium! That's a significant formulation change.

They did the same thing with regular Maxlife.

Well slap my [censored] and call me Charley; they've reformulated all their oils like this, to include Synpower.

It will be interesting to see if edge uses sodium. Could that be the silver bullet that's beating Mobil 1?

The NOAKs are all much lower now as well. Valvoline is putting out some top quality product.

If sodium is a magical substance (it probably is) then I have no problem with them using it as an additive, even if it makes detecting a coolant leak slightly more difficult.

Most of the used oil analysis I've seen of oils that had high levels of sodium had pretty low wear numbers.
