All those 3 are new in 5 L jug at my local walmart, the supertech is a good price, any good compared to the other two?

Thanks

Over a short interval? Likely the same results. Where the RP and EP will shine is with an extended interval.


I'm a thickie; but a 20 has its place.

I use AMSOIL

Those would be my OCIs running those 3 brands.
I have no fuel/coolant dilution concerns and I run a 50-50 mix of highway / city.

The M1 may have better Base stocks but who really knows which is better.
