Redline heavy duty shockproof oil I would assume. Somebody may correct me.

Dark One is correct, Redline is what I was told to use in mine, awesome stuff.

Go the Redline way.
Resists water and keeps quickies cooler than ordinary gear oil.

Before you rush out and waste a lot of money on redline, I thought I might share an opinion.
The business I run is one of the largest consumers of oil in the south island, and we work very closely with our suppliers to keep upto date with oil technology. Over the past couple of seasons we have supplied and sponsored several superstocks with oils. At least three of these have winters quick change diffs. I did significant research on the oils which were suitable for these diffs. Winters even sells it own branded oil. Ultimately the results showed that any ep gl5 diff oil would do. Preferably with an lsd additive, although not critical. I approached Cardwells about redline, and I quote "redline (haha), that just sucks the horsepower". I know there is a preference for redline out there, but no matter how hard I looked non one could give me sound reasons for wasting money on it, as opposed to regular ep gl5 oils.
The conclusion was any quality brand ep gl5 oil does the job, the thicker the more horsepower drain though. Winters own oil is a simply 80/90
Cheers

Not knocking your research etc but Winters also recommend tearing down their diffs every 10 shows and replacing bearings etc.
After rebuilding many diffs and gearboxes out of racecars I have found the heat discolouration,distortion and overall wear is reduced by using Redline and similar race only oils.
You can get more life out of the gear overall.
The heat difference when operating is huge.My open wheel customers have noticed immediate difference under their bums when they have switched to Redline and the like.
As for being a HP sucker,yes its true....from stone cold!!!
Engine as well as drive train should be warmed up to operating temperature before racing where possible.

you wont get a straight answer out of Cardwells about redline oil as the distributer and cardwells went toe toe over the importing and advertising of redlne products ask the other suppliers of race car parts what they use and u will find most recomend heavy shock proff and yes warm your diff up it also makes it last longer also remember diffs need servicing just like engines quickchanges loose there sidebell preload once this happens kiss the gears goodby

With the risk of hijacking this thread a little. A couple of statements made in this thread highlight what I feel are the biggest issues. We, In NZ, tend to use products and parts for much longer than intended by the manufacturer. Maintenance, maintenance, maintenance, seems to be what is needed. Don't be afraid to replace bearings and oils regularly. I know of a super saloon driver who replaces the oil in his bert box, every 2 meetings (1.5l of atf bw, not a huge cost). He has never had a gearbox failure in twenty years. It always amuses me when guys change diff oil in the pits, and reuse the dirty used oil. Regardless of the brand, the dirt in the oil is still the same. Oils are a cleaning and cooling product, for such a small cost (compared to the car) changing them fequently seems cheap maintenance. The other thing I can see from this discussion is the need for rebuilding diffs etc. I for one think it is better to spend a bit of money freshing gear pre season, not forking out significant coin after a parts failure.
Ok hijack over

Ok hijack over Cheers DJared[/quote thanks for all info and input into this thread, Hi have taken your reasons for and against and have chosen to go with the EP gl5 lsd oil the reason being more cost effective than the likes of the redline brand i can do regular oil changes @ 3 to 1 . for the same $. Doing more regular oil changes over the season will reduce wear and tear hopefully. |

Have to agree with autopete on this one, have used a few `brands' in my 20 plus years of speedway involvement and personally would not waste my money on anything but redline oil especially in the diff
