I am using Royal Purple synthetic with very good results. The standard fluid made steering very stiff in sub zero temps. I imagine any syn PS fluid would have the same results. 130,000 miles and pump still running good.

I switched to Royal Purple synthetic when I moved to MN. When below 0*F the steering was very stiff with the regular PS fluid. The steering would hardly turn when below -20*F. Now with the synthetic it steers very smoothly even when -30*F. It also steers much smoother in the warm weather. I...

I was able to find Royal Purple synthetic power steering fluid at the local Napa store. It works great in below 9 temps. The steering is much easier.

Well I just used it to fush and refill the PS fluid in my vehicles. There is a MUCH stronger pungent oder to it compared to the old formula. Not sure but, I think it is a sulfer smell?

The Motocraft 15W-40 has a good VOA. It high in silicon to prevent foaming. I read somewhere that the crankcase oil is used to pressurize the injectors in the Fords ( Not sure which diesel engine it was though.) The original oils foamed sometimes which cased problems.

Did you forget to take the turkey baster out?

I have a Chevy Silverado with the Saginaw PS pump. Thet are notorious for stiff steering when cold. I moved to Minesota and when in the minus degree temps the steering was impossible until it warmed up. I flushed with the Royal Purple synthetic PS fluid. The improvement was tremendous! It now...

I have used the STP fluid in my 2003 Chevy Silverado for the last three years. I change it once a year. Put about 20K miles/year It works fine. It actually steers better than the original fuild did in the winter.

I am using Havoline. It's one of the best VOA's arround for car motor oil. Good detergency.

Follow the same order.

To get most of it out with the turkey baster method you have to do it several times. I bought 2 qts of PS fluid. Suck out as much as you can with the tukey baster and fill with new. drive for a while and repeat the process until the 2 quarts are used up. It will be nice and clean by then.

Ops! Sorry folks. I did not mean to imply not to routinely change brake fluid. I was just wondering what the manufactures are claiming by stating their brake fluid is “synthetic.” I understand what synthetic motor oils are and their benefits. I do not understand what a synthetic brake fluid is...

DOT 3 and DOT4 brake fluid are not petroleum based so if you are thinking you are buying a “synthetic” (better?) in the same context as a PAO or Ester, you are not. DOT 3 and 4 fluids are glycols (similar to what is in antifreeze. Therefore, I am not sure what a synthetic brake fluid is. I am...

Motor Craft is at the WalMarts around here.
