Silkolene Silktran Syn 5 is great stuff if the gearbox is in good condition, if not any wear can become more obvious when using it. Motul Gear 300 and Redline Lightweight Shockproof are good if the gearbox has been showing some wear.
You have 3 Castrol Syntrax oils in the 75-90 section, which is best to use? In particular for my 99 Sti Ra Ltd, which has a Helical Front Diff (LSD I believe) and LSD in the rear diff as std. I have a post in another thread waiting for confirmation on this........... Anyone?
Just changed the oil in my 2.5xt Foz.
It had been grinding going into 4th both ways for the last 30k.
Bought 2 quarts of redilne shockproof and topped up with 75/90, it now changes silky smooth even under hard acceleration.

Someone put cheap rubbish gear oil in my old WRX and I had difficulty in engaging first sometimes, and it wasn't smooth at all.
Switched to Castrol Syntrax and the difference was night and day.
I've read brilliant reviews of Motul Gear 300 and Redline on Nasioc and MLR.
Just goes to show it's not worth skimping on gearbox oil!
Hi, can anyone please give me some advice about my 2006 Cat D Forester with genuine 7,000 miles. It had front damage (surprise!) which lifted and pushed back the engine 2 or 3 inches.
It jumps out of 5th gear with great force after being run at motorway speeds for 20 miles or so and does so continuously every few seconds until I stop and let it cool again.
I can run it around at 60mph without it happening at all.
Gears engage without problem and feel solid enough, but it's not possible to hold the gear in place when it goes.
The oil has never been changed and there are no signs of a leak
