AMSOIL Introduces 10W-60 Oil

[Cronenberged]

I've been running their Signature 5W-50 for several years for it's high shear stability and reduced wear. I know how much everyone loves a good oil thread so thought I would share.

Back when I was a teenager I used to work at a machine shop that was owned by this old timer in his 80s, and he'd been building engines for 60+ years and did a lot of Ferrari heads and other imports, and he SWORE by Amsoil. Said it was way better than anything else.

Friend of mine swears by Amsoil as well. I've talked to their reps. I don't know what to think of it all, from valid chemistry and extended oil changes on their top end oils, to basically "it's the same as Mobil" on their entry oil. Castrol right now is cheaper on AutoZone, and at a 5k interval, I'm sticking with that.

I’ve run the same, because it is better than everything else. In the Allroad 4.2 it’s the only oil that doesn’t get smoked like Marlboro Lights. I spent far too much time analyzing the MDS on these oils, may even have a spreadsheet somewhere. I’ll check my computer.

But to PSUEng’s point, I’m also on 5k intervals on all the cars, mainly because it helps me remember and that’s over a year on all of them. So the Castrol Edge 5w50 that no one seems to know about is just fine in the Allroad.

If I used my M3 the way BMW marketed it, I’d definitely use Amsoil. But for my use the LiquiMoly is probably just fine. Any boosted M3 here should definitely give this a look. It was more sheer resistant and held up to heat better than almost everything. Back then it was just hard to find (had to be pre-Covid when I was looking).

EDIT… this is what you need to see… https://amsoilcontent.com/ams/lit/da...tins/g3395.pdf

Notice how the viscosity at boiling (100*C) is so much higher, as is the Flash Point, yet the water Weight Loss is very low (this is how engines smoke oil) and the Shear Viscosity is higher. Whatever tech they developed to get this, I’d expect to see it filter down to other weights. This looks like great stuff to me.
