the NS is lacking the additive for limited slip diffs it may cause chatter. the 75W90 has the additive. read here: http://www.redlineoil.com/products_gearlubricants.asp?productID=35&subCategoryID=15&categoryID=6
I personally talked to a tech at Redline and they said just use the NS for our 308s... no need to mix or use additives of any kind. Mine is a QV and I've used Redline for about 3 years and it's GREAT.
Manny, I got mine at a local auto store. But you may have to go online to find a local distributor or order online.
i bought the redline heavy shockproof gear oil with a red label. is this the right stuff? it doesn't real say on the bottle. wasn't cheap either. 5 quarts was like 90 bucks.
Thanks Branko! I checked today with a parts store right down the road and they said they can order it and it will be here within a week.
I found this: "Red Line® Heavy ShockProof™ - a 75w90 GL 5+ gear oil with an EP250 rating. The lubricant contains a suspension of solid microscopic particles as an extreme pressure agent giving magnificent wear and film strength with minimal power losses. Perfect for large dog boxes, very heavily loaded synchromesh boxes, differentials under extreme load and any particularly high temperature gear train. Heavy ShockProof™ is suitable for gear protection in the most extreme circumstances. Suitable for use with all LSD types." Looks like its the right weight & says its OK for all LSDs so I would think it'll be fine - if not overkill even. If in doubt ask Redline. YMMV, on your own head be it, don't blame me...etc etc etc I.
I drained my car and I ended up with over 5 quarts coming out. I know it was done at the dealership last so I figured that there was a reason for puttin in the extra. When I refilled it, I used the method of refilling it through the clutch bell cover and let it drain to the pan. It took all 5 quarts before it started to dribble out. I took it out for a spirited drive on Saturday and it performed flawlessly. I never had much of a problem getting into 2nd gear cold, but it was even smoother after the change.
it sounds like the right stuff. there was a thread here awhile back about it. i just hope it's not to much. i suppose it can't hurt it. the temp down here is always pretty warm so i don't think cold is an issue.
anyone know where to get redline gear oil in houston? the usual places (o'reilly's, autozone pep boys) don't seem to carry the gear oil
I have used Red Line in previous non-Fcars with good results, particularly for cold weather shifting, and will be switching over to 75W90 NS in my '89 T during an upcoming gear oil change. The book calls for 4 litres, just over four quarts. I was able to order 5 quarts from http://www.synlubes.com/redline/gearoil.html that came to about $56.00 with shipping by UPS ground. They carry a range of Red Line products.
No, it's on the corner of Richmond/Greenridge, west of 610 loop. Greenridge lies between Fountainview and Voss/Gessner (I think!!) Greg
I ordered mine from Al Smith Automotive Supply yesterday and it was at the office this morning when I walked in, easier that driving down the street for it. http://www.synlubes.com/redline/gearoil.html
I had to special order Redline at the autoparts place. I got the NS, the regular, and the MT90 for the three cars. (Now I also need the lightweight shockproof for the EVO's transfer case, which can't tolerate the heavier oil when cold.) The 75W90 regular in the Alfa's (LS) Diff eliminated the whine it had developed. For the most part, you can't just pour the oil out of the bottle into the trans/diff case. I used a manual pump to push oil into the diff on the Alfa, but kludged up a pressure transfer gizmo for the transmission ... I got tired of pumping manually. But be aware: Gear oil is nasty stuff. Open only in a well ventilated space. Next change, I'm going in MOP-3.
Isn't that bizarre? Gear oil, unlike motor oil, doesn't get diluted with gasoline or have the tendency to get acidic, so it's not as time-sensitive... once a year is overkill in my mechanic's opinion, and I'd have to agree with him.
Not being an expert I tend to advise people to follow the manual, but in this case Im with you, Mike. As I recall my mechanic, who has a lot of Ferrari experience, suggested every 2 or 3 years.
