Found this Mobil 1 oil at WalMart and I have a question

[Six Guns]

Is this oil O.K. to use on our valks. It doesn't have energy conserving on the bottom half of the circle. I didn't see that it was diesel oil which concerns me. It says that it's for high mileage engines, and fully synthetic. It's priced right at $3.68 a quart. What do you oil experts think? Sorry about the quality of the picture, I took them with my cellphone camera.

I remember when other branded oils, Castrol, etc, came out with the high-mileage oils, there was an addition of something slick...  either zinc or moly.. ??

I'm getting old & have CRS disease....

Their product data page just says "extra anti-wear additive"

I and many others use Mobil 1 15w-50    .  Has the same empty bottom part of circle you referenced.  But as you know, there are many opinions vis a vis oil brand and weight    .  No doubt you'll hear from those who have a different view very soon

Six, look at the "API service symbols, usually SM, SL, CF can be used in diesel service. No energy conserving additives added.

On the bottle it states API: SM,SN,SL.....
