Hey Kale, I was just wondering how Amsoil holds out against Castrol fluids. Which ones better? (just curious)

 

I think you might get a biased answer there... He likes and sellsAmsoil... LOL!

This link should more than answer your question:

Thanks Bill <IMG src=smileys/smiley1.gif border="0">Im suprised castrol wasnt all that good... Amsoil it is then in the future!

 

Viper, just let me know when you're ready to get your AMSOIL, I'll hook you up.



Remember those tests are done by ASTM, not amsoil.



And yes we're a little biased, simply because it is the best<img src=smileys/smiley1.gif border="0">



take care



Kale

 

Thanks Kale, but its gonna be a few years before i even decide to get a car. lol. I dont want to dig myself in debt by having a car but no job, so im gonna get a car when im 18 or 19....when ive got a job. lol. </P>

Not sure if this is the right thread to post these questions since it is referenceing Castrol.

Is there any study/comparision between Amsoil and Red Line?

2nd Question - What is the difference between 10W30 and 10W40? I was reading on some other forums that the 40W will decrease Horsepower on my 1995 Nitro Yellow Green Dodge Neon?

The 2nd Question is because I wanted to run a High Performance Oil in my race car and Amsoil does not have a High Performance Oil in the 10W30 - so I am currently using 10W40.

Thanks
Greg P.

 

#1 Not that I know of.

#2 The difference is the Kinematic viscosity or Thickness. The 10w-40 is "thicker" than the 10w-30. When your oil is extremely hot, the 40w is less likely to thin due to its thicker viscosity. This provides increased protection in tough conditions such as sustained RPMs, racing, or driving with the A/C on, in traffic, and during the summer.

I highly recommend that you consider Amsoil's new European 5w-40 which is more performance oriented than their older 10w-40. Here is a link to it's specs: http://www.amsoil.com/flash/afl.htm

[quote]AMSOIL Synthetic 5W-40 European Engine Oil is specially formulated for the lubrication needs of European gasoline and diesel cars and light trucks. Formulated with advanced AMSOIL polyalphaolefin (PAO) synthetic base stocks, premium additives and a broad 5W-40 viscosity rating. AMSOIL 5W-40 allows motorists to take advantage of the maximum extended drain intervals recommended by European automakers while providing second-to-none protection and performance in the most demanding operating conditions.


Maximum Engine Protection
AMSOIL Synthetic 5W-40 European Engine Oil surpasses the North American SAE and European ACEA oil specifications for high temperature/high shear (HTHS) viscosity. It does not shear back to a lower viscosity oil in the high temperature/high shear conditions of today's smaller, high RPM automobile engines. AMSOIL 5W-40 contains high quality anti-wear additives for superior engine protection. It resists the damaging effects of heat, blowby chemicals and oxidation for extended drain intervals, providing cool, clean and
efficient engine performance.

Reduced Oil Consumption
AMSOIL Synthetic 5W-40 European Engine Oil does not vaporize (burn off) in the high temperatures that vaporize conventional motor oils. It provides consistent high temperature protection, improved fuel economy and reduced oil consumption and emissions.

Provides Low Temperature Protection
AMSOIL Synthetic 5W-40 European Engine Oil remains fluid at temperatures as frigid as -59°F (-51°C), permitting easy engine cranking for fast starts and immediate start-up protection, greatly reducing engine wear and prolonging engine life.

Prevents Rust and Corrosion
AMSOIL Synthetic 5W-40 European Engine Oil contains special rust and corrosion inhibitors to protect iron parts, as well as copper, lead and aluminum bearing materials.


Meets or exceeds the following specifications for domestic and foreign gasoline engines:

API SL, CI-4, CF
ACEA A3, B3, B4
BMW LL-01/98
