Default Question After Open Track

GOT SMALL DILEMMA AFTER LAST SUNDAYS GINGERMAN

first of all i put 75w-90 like manual asks for and that was mistake, grinding and shifter felt like it is water inside

i put 80w-90 from amsoil and everything was fine until i did 2 sessions almost on after another, 4th gear started grinding little bit

my concern was it was pretty chilly out there so probably it will be much worse when it is gonna be 100 outside

my friend is pushing me towards motul, he claims all his problems went away when he started using that

car got 90k already,

do you think better/thicker oil can help or synchros are just starting to ear out??

It's not always just the oil's weight that affects the operation. I'd suggest draining the Amsoil out and refilling with Extra-S. See how that goes, it has worked for more than a few people. Motul is another that gets good comments but may not work in every case. Extra-S is slightly cheaper than Motul so why not? There are vendors taht sell Extra-S by the quart instead of the Subaru "mighty" pail.

the dealer is an idiot just like 99% are.....and yeah....you may wanna use a racing fluid for the track

the extra s may work but wont last long....and if ya gonna track the car, plan to change all the fluids a LOT more regularly

Lol I dunno I ran Mobil 1 75-90 and a qt of synchromesh in all my cars without an issue but I changed it almost every other oil change that's a lot of heat you're putting into that fluid and in the trans breaks down a lot more quickly hence the point of possibly switching to something race oriented

the synchromesh is quite thin and wont really hold up well...which is one of the reasons i changed 'the cockail' mix to reduce the quantity used

you could likely use 1/2 quart and still get the same benifit as using a full quart....and also beinifit from having a bit more regular lube in the trans

a little synchromesh goes a long way....my first experiment was adding 200ml of synchromesh to my trans and it was glaringly apparent that just that little bit had been added

^i agree with that the only reason I think I never ran the cocktail was purely do to price I had good results with Mobil 1 and synchromesh and had a friend who worked at autozone so it was basically free and I had good results so I ran it If I coulda got the cocktail stuff that cheap woulda done it to

Sort of, Extra-S is a Subaru product but it is certainly not the dealer fill oil (I'd only believe them if I saw them open a new drum and pour directly into my car). Extra-S is 75W90 as any 10 second Google search will find for you. Extra-S is non-synthetic that performs well with the 6MT syncros in most weather conditions.

As he noted, servere use will certainly use up the additive goodness in any oil, decreased drain intervales is a must if you do a good deal of track use. I also agree that the dealer is a moron who has probably never read the service manual.

v - As in "Subaru Extra 80w90" and "Subaru Extra S 75w90"? i've not looked that much into it, so I have only bought Extra-S 75w90 that is imported from Japan in the larger pails.
