I changed to synthetic fluids because of the SC. When I take the SC off later on, do I need to go back to regular fluids or could I still use the synthetic fluids?

 

Either as long as your engine is still mechanically sound. Sometimes it is touted the use of the hi-cleaning synths allow some dino ois to lek thru. I would only tell you this as I saw it once in Georgia the driver should have stuck with the synthetic quality not immediate cost savings of regular oil...but his case was with a moderately healthy engine...borderline.

 

Most synthetic fluids state that are compatible with conventional fluids. Well, the synthetic oils are...dunno about stuff like brake fluid.

Most people do not need the additional protection of synthetic fluids, even under extreme conditions. The exception is if you live in -30 or 120F weather, in which case synthetic motor oil will save your engine on startup and stop and go traffic. But if you do switch to synthetic fluids such as motor oil, ATF, MTF, etc...might as well stick with it. Once you get the best, you won't want any less for your car.

I've had good results (i.e. no problems) with Mobil One and Redline fluids.

 

Where I live, there's a lot of stop and go traffic, so I might just stick with synthetics. I also have to say that I haven't had any problem since I put synthetics in my car and I'm currently running about 10psi of boost on my car.

 

Synthetics will not hurt anything. In most cases just help out a little.
