Lots of talk over on the SubaruForester forum about this stuff for use in the subie front manual transaxle. It's a synthetic GL5 with no limited slip friction modifiers. Where does one buy this stuff? Is it available only from mail order? One "eggspurt" over there says it's a lot better than Redline 75W90NS, which is also GL5 synth with no limited slip friction modifiers. Subaru says specifically not to use oils there with LSD modifiers because it interferes with the tranny synchros (too slippery). The Eggspurt's recommendation is a cocktail of the Motul mixed with a quart of Redline Lightweight Shockproof. Anybody have any experience with this shockproof stuff? Thanks.
