Engine oil AMSOIL or Total

I use Amsoil 20w40 in all of my semi truck motors. I change it according to what the lab says the condition of my motor and oil. I am going 100,000 miles on my over the road trucks. I go 25,000 on my power stroke and could go much farther.

I switched to 5w-30 instead of the factory spec 0w-20 and that slowed down my consumption. I use Amsoil to maximize protection with use of the "wrong" oil weight and I monitor wear with oil analysis and seem to have no change in wear from my 0w-20 use.

Total Quartz is really good value esp Quartz 9000 that is top rated API grade im 0w20 full syn

Io ho sempre fatto i tagliandi in Citroen e mi mettono questo olio:\n\nTotal quartz ineo 0w20 B712010(C5)

i use AMSOIL 0-20 in my Vezel. Runs great, maybe slightly better them LM.

I used Amsoil Signature when I was driving 1300 miles a week just so I could go two months between oil changes.

I change oil once per year, using a high-quality synthetic that meets specification 504. I generally drive 8 to 9 thousand miles per year. The maker of the oil I use (Amsoil) says to follow the car maker's change interval.

For me at least, I use a 5w-30 Amsoil on my TLX Type S.

I never ran Pennzoil, but I have Amsoil. Amsoil is good, but too expensive.

I don't like dominator because it's not colored have to be extra careful to not screw up the jugs or forget to put it in. At least that's what I remember, I could be wrong.
