Synthetic and Horsepower

I'm with **** on the benefits of the Amsoil Series 2000 lubricants when it comes to generating maxiumum Hp....

One of the benefits of the Amsoil 0w30 is that it can be substituted for higher viscosity oils (10w-30/0w-40/5w-40/10w-40), without compromising wear protection. This can and will result in small but consistent gains in Hp and/or fuel efficiency, depending on how you want to look at the effect.

Amsoil has shown printed dyno test results on 358 cid engines (ie Winston Cup cars), showing gains of several Hp wih their Series 2000, 20w-50 Racing oil. I've also seen a dyno run of their 0w30 on a 3.0L, Ford Taurus engine (140 Hp) showing gains of approx 3 Hp and 3 ft-lbs of torque, compared to a 10w30 Castrol conventional oil.

Dollars to donuts the weasel that gained 3 hp (HUGE % GAIN) in a B&S engine did the measuring when the engine was cold......and this totally validates what I posted.

A friend of mine noticed (did not test on dyno)a gain in power when switching from Mobil 1 5w30 in his Vette to Amsoil S2000. You'll notice even RL's testing (old test) on S2000 showed it having a very low coefficient of friction. The S2000 does have very good frictional properties. Redline does as well.

My car calls for a 5w-20, but so far the Amsoil I have in feels as good as the RL did. I think the GF-4 5w30 Amsoil has been improved. GC was sluggish. All the other 20wts were great.
