Amsoil Signature or Dominator Series?

[Nighthawk89]

Which one for a DD car that can get rippen sometimes on the freeway and thru the canyons. I change every 5k miles.

Man to be honest with you if it were me i would go with the Signature series in either a 0w30 or 5w30..both have a higher TBN then the dominator series which in my opinion would be better suited for a street driven car...5k miles is also a very short interval for that oil, almost a waste of money..but i understand oil is much cheaper then an engine. But if your car is running stock engine internals i would atleast go 8k miles on the signature series...or wait until the oil life monitor is around 30-40% if that makes you feel better. Seriously though a conventional off the shelf oil can easily do a 5k drain interval...i would get my money's worth of the signature and atleast run it too 8k or so..Just my opinion..Either oil though is very good..probably about the best money can buy so you cant really make a wrong choice (especially if your adamant on 5k drain intervals)

Great Advice! Ive always been told 5k intervals so ive just stuck with that. I agree with the recommendation of the signature series.

Or if you are crazy like me you would grow balls to run it for 12000 miles,,, oh and by the by when I send the sample back to the lab its comes back with at least a few more thousand miles of life,, oh and 10 months straight.


I would agree that Sig series would be best,, and can be ran for 8k miles hands down... Dominator if you are looking for the best of the best protection while racing and heavy modified car

Dominator track only. I did however use it for a few days. More torque less cleaning detergents.

Just make sure you don't use a high end oil like Signature series and skimp on the filter

Signature series for sure. Dominator if you track alot and change frequently. It has hardly any corrosion inhibitors and is not good to let it sit for long periods of time. I spoke directly with Amsoil Tech on this.

I run Zrod and change to dominator for track use then change out back to Zrod. My motor is way different from yours however.

Signature series is perfect for you.
