its incredibley hard for me to find Red Line products here, no one seems to carry the, along with the purolator filters.

but royal purple abounds on the shelves of every store.

I know many of you use either or both of their products, but anyone think one has an edge over the other?

to be more specific im mainly talking about their 10w40 and atf fluids

 

I enjoy Amsoil ATF, Redline waterwetter, SI-1 and OEM filters.
I also enjoy Miller Lite and a stout once and a while.

I've heard of many car clubs in Houston, if you can get in touch with a member there, they can guide you around to where some speed shops are. You might want to buy them online. Trussville Mazda has discounts on filters. Pep Boys should carry Pure-One oil filters, ask the dude at the counter. Amsoil does mail order online and Redline is carried by many performance shops in Texas. Good Luck.
