Which Auto Transmission Fluid ?

[Arthur-UK]

My SVX is due for a transmission fluid change.
Should I stick with the specified dexron II or use a synthetic ?
What Sythetics are being used in the SVX ?

I don't know what's avaliable over in the UK, but everyone seems to like synthetics over here. Aside from Mobil 1, the only transmission fluid I've heard people speak highly of is called Redline.. apparently it's good up to a much higher temperature than most other synthetics..

the fluid I speak of is..............ROYAL PURPLE !!!!IF YOU NEED HELP FINDING IT LET ME KNOW..I run royal purple in all my vehicle's (2000 isuzu rodeo lse,94 mitsu galant ls, 94 svx l,92 svx lsl rico edition) and recommend it to friends/family/associates alike cause it really works and it's results are felt almost immediately !!I pay $5.25 a qt. for eng. oil 10/30 (winter) 10/40 (summer) and $7.00 for the tranny fluid and the beauty is with synthetic it last so much longer a prtects so much better it is perfect for the SVX... holla at me if you need assistance with it....

I'm using Royal Purple in the engine & tranny, I think the products are tops.

Subaru tech bulletin 9002006, Feb 1990, on tranny fluid hints that the lower the number for viscosity (cPs) at -40 degrees the better the fluid (Subaru stating the lower number indicates the quality of the base stock, or an expensive refinement method).

Anyway, a quick search from the companies own web pages found this data:

Royal Purple 7934

Amsoil 7150

Mobil 1 6200

Redline 45

I don't work for any of these companies - can't say how truthful any claims are. Redline's seems suspicious - or I have collected bad data - as Subaru goes on to state the best synthetics approach 5000. Draw your own conclusions. BTW, the Dexron II spec is 50 thousand or lower - according to the same Subaru tech bulletin.

I have been using the Amsoil with no problems.
