I would suggest runnign just normal 5w30 motor oil or a MTX oil such as redline MTX.
There is some concern about whether the synthetic is too slipery for the synchros. I had a 10k mile failure on the second gear synchro on my 568 when running mobil 1 0x30 a few years back so I stick to the cheaper conventional or MTL now. -Rich On Fri, 11 Jan 2008, Bill Schulze wrote: > Date: Fri, 11 Jan 2008 05:48:39 -0500 > From: Bill Schulze <[EMAIL PROTECTED]> > To: shelbydodge@imagilist.com > Subject: SD> Transmission oil > > What weight Mobil 1 should I use in my 87 CSX? > ___________REMOVE-FOOTER-WHEN-REPLYING_________ > ShelbyDodge mailing list > ShelbyDodge@imagilist.com > http://www.imagilist.com/mailman/listinfo/shelbydodge > ___________REMOVE-FOOTER-WHEN-REPLYING_________ ShelbyDodge mailing list ShelbyDodge@imagilist.com http://www.imagilist.com/mailman/listinfo/shelbydodge
