Amsoil in 986?? Anyone using it? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

A friend of mine was a Ferrari mechanic and talked me into using this on my shovelhead (40wt racing oil). Says it extends the life of the engine and was amazed at how clean the engines were after using Amsoil.

I have had great success in my old shovel, runs cooler and always comes out clean.

Wondering if anyone has used it on a boxster.

thanks -c

I have not used it in my 986s, but I did use to always use it for my old MBZ 400e that was lightly modified, and yes I did notice a big difference when I switched to it, but my car back then was not on synthetic oil, that was the first taste to it. I don't know if it is any better than mobil1...definately much better than the non synthetic oil I was running

I have on my 2000 S and I notice a big diff in power and coolant temp very little noise on cold start I also have a cayenne and that as royal purple is ok but not as noticeable as the amsoil in the boxster

I use torco sr-1 synthetic: www.torcousa.com

Smoother engine, and a little power to boot.

Amsoil makes a fine oil.

1-I assume you are NOT talking about using the straight weight 40 oil in the Box.

That is a no-no.

2-Amsoil makes two versions of its oil. One is a G3 syn and the other, a G4. If you buy, makes sure you buy the g4 and in the appropriate weight.

For my money, Red Line is the best out there.

5W-40 is the deal.

Good luck.

Hi,

C'mon guys - a Power Boost from changing brands of Oil??? PUT DOWN THE METH PIPE! JUST SAY NO!

Even if that were true (which it isn't), show me a Dyno sensitive enough to detect the change...

Come to think of it, I have this pair of Chinos, and my car always has more power if I wear them...

I have to say that I have NEVER experienced this "my car runs smoother on oil X".

I have heard this said many times but I have never heard HOW that could happen.

Anyone know how an oil switcing from one quality oil to another could do this?

Obviously this is from the advertiser's site so it's a lot of slick marketing, but then again I know basketball players that always wear the same color socks on game day and swear by it.

Synthetic 20W-50 Racing Oil
Keeping friction low helps hold down engine wear rates and temperature. Which helps engines last longer. Reducing friction also conserves fuel. But the real benefit of superior friction reduction in a race engine is greater speed. Speed, after all, wins races.

Some of the energy produced by the combustion of the fuel-air mixture is consumed by friction along the way from the combustion chamber to the flywheel where torque and horsepower are measured. The more energy that escapes consumption, the more torque and horsepower there is available for moving the car.

Hes got you there Jim, i dont think an essay will get your past this one.

Oil viscosity is a complex subject.

In theory, you want just enough oil film and volume to avoid metal to metal contact and to cool the engine. Too much viscosity and you waste fuel and lose a bit of power.

Too little and you have premature wear or worse.

The 20W-50 MIGHT make sense in some applications but certainly not for Boxster street use.

Hi,

All true. Too much viscosity and you don't have good flow. Also, heavier Oils create more Drag on the Crank, robbing Power.

15W-50 MB1 is what I use in the Esprit, but it has the much harsher Turbocharged environment to deal with, and it's a 23 y.o. car - the technologies and metalurgies were different then. And, 15W-50 is what the Manufacturer (Lotus) calls for...

Indeed, I am sure the Esprit can use every bit of viscosity in that bad boy!

Hi,

Don't know how you figure that. Aside from stating the obvious, there isn't a whole lot of information there - it's just Hype.

Oil reduces Friction - there's a revelation - Stop the Presses, Film at 11...

A Racing Engine is an entirely different animal - purposely designed to much Looser tolerances. A Race Engine develops more, not less Friction.

And remember, we're talking about a comparison of one Oil to another, not whether Oils aren't lubricants.

There's very little friction in the Oil Bearing internals of a car - the Crankshaft, Big-Ends, Small-Ends, Pistons, even the Cam lobes have no metal-to-metal contact, at least in theory. All these components Float on a film of Oil.

Again, any quality Oil with the same viscosity will not create any more Power than any other. You can think so if you wish, but it's Myth.

A lot of people say that a new Oil makes the Car Smoother or Faster, but their comparison is to another Oil which is used, Broken Down and Dirty, not when that other Oil was new...

Happy Motoring!... Jim'99
